Description

Technical Field

[0001] The present invention relates to an indoor method for treating organic waste, preferably food waste, with minimal human intervention, in which the accumulated organic waste is stored and fermented for a given fermentation period under incomplete anaerobic conditions. The method is useful for treating organic waste, preferably food waste, in the living environment of humans indoors, such as an office environment. The present invention further relates to a waste treatment device for carrying out the method.

[0002] The idea of the present invention is that organic waste in such an environment is safely and simply treated in a closed device that provides incomplete anaerobic conditions without emitting odors, while on the other hand subjecting the waste to a fermentation process by applying a plurality of times a microbial preparation at a frequency that induces fermentation in a direction that can lead to the formation of products suitable for the composting process, specifically for soil improvement. In one embodiment, as a result, in an optionally closed (anaerobic) environment, a partially fermented product is produced that can be further fermented into a material directly applicable to soil improvement. The present invention further includes a waste treatment device for carrying out the method.

Background Art

[0003] Composting is an important and easy technique for minimizing waste and providing nutrient-rich soil for plants in several respects. 1. Waste reduction: Composting converts organic waste from landfill waste, thereby reducing the amount of waste that ultimately becomes landfill waste. 2. Soil fertilization: Composting provides nutrient-rich soil that can assist in improving the health of plants and gardens. 3. Reduction of greenhouse gas emissions: When organic waste decomposes in landfill, it produces methane, a potent greenhouse gas that contributes to climate change. Composting reduces the amount of organic waste in landfill, thereby reducing methane emissions. 4. Financial savings: Composting can save money on fertilizer costs and reduce waste disposal costs for local governments. 5. Improvement of soil structure: Composting helps improve soil structure and reduce soil erosion. 6. Safe and Sustainable: Composting is a safe and sustainable method of managing organic waste because it relies on natural processes to produce usable soil.

[0004] While traditional outdoor composting is widespread and used in numerous forms, indoor composting is becoming increasingly popular, offering the same benefits in a more manageable and convenient form. Indoor composting is particularly useful for urban dwellers who may not have access to outdoor space, or for anyone seeking methods to recycle food waste at home and / or in the workplace. Indoor composting also serves as an excellent teaching tool for learning about the importance of environmental sustainability and waste reduction. Nevertheless, indoor composting is critical from several aspects of environmental psychology. For example, office or workspace environments, or social spaces, are particularly sensitive to environmental sanitary aspects such as odor, accidental contamination, or other unpleasant effects. Traditional indoor composting methods were primarily suited for home and educational use because the methods used were not suitable for office / workspace environments. Most indoor methods require significant user involvement (such as composting methods or aerobic composting methods) or are unsuitable for the office market from a safety standpoint (insect or larval composting). Current disposal-level indoor electronic composting devices are not robust enough for professional use, and food waste needs to be processed relatively quickly and frequently to avoid the undesirable effects of untreated food scraps (e.g., odor, contamination).

[0005] Furthermore, most such electronic devices have significantly high power consumption, making them more environmentally unsuitable for processing organic materials. In places where a substantial amount of food waste is generated on a daily basis, professional and sustainable responses are possible, as the option is to remove the food waste daily and process it at specialized sites. However, in areas where the amount of organic waste does not justify daily collection (either from an economic or environmental sustainability perspective), and where food waste is generated at varying frequencies but collected only locally, such as urban offices or kitchens, traditional methods like vermicomposting or aerobic composting do not offer viable solutions.

[0006] In her review paper (Margit Olle (2020): Review: Bokashi technology as a promising technology for crop production in Europe, The Journal of Horticultural Science and Biotechnology, DOI: 10.1080 / 14620316.2020.1810140), Margit Olle provides a detailed overview of bokashi technology for food waste recycling and the use of its products in crop production. The authors summarize that "bokashi fermentation of food waste using effective microorganisms (EM) is a form of biological treatment that stabilizes biowaste and provides a nutrient-rich growth-promoting fertilizer for field and greenhouse-based food production systems."

[0007] In bokashi technology, when applied to food waste, the compost is removed from the bokashi container ("bin") after the completion of the bokashi composting process. Typically, mechanical treatment such as spindle shaping and / or pressing is required, resulting in the separation of the liquid phase, "bokashi tea." If the moisture is not removed, it condenses within the closed container of the composting bin, leading to increased temperature, longer composting times, and undesirable microbiological processes such as mold formation (Citation: L|ew, PS; Nik Ibrahim, NNL; Kamarudin, S.; Thamrin, NM; Misnan, MFOptimization of Bokashi-Composting Process Using Effective Microorganisms-1 in Smart Composting Bin. Sensors 2021, 21, 2847. https: / / doi.org / 10.3390 / S21082847).

[0008] A method adapted for food waste disposal in office environments has been proposed by Compocity Kft (https: / / www.compocity.help / en / technology;WMN ReStart:A robot,amely forradalmasitja a varosi komposztalast-A Compocity a Best Impact Award jeloltje-Szavazz!2022.majus 3.). This method involves using a device that includes a bin with a resealable door for introducing food waste, and the composting method involves semi-anaerobic techniques in a space that is often exposed to ambient air, while a mechanism operates inside the bin to separately collect the removed liquid.

[0009] Prior art publication International Publication No. 2016038518(A1) discloses a discontinuous reactor for the biotransformation of organic substrates under anaerobic conditions, and a process for the biotransformation of organic waste through dark fermentation under imperfect anaerobic living conditions. The reactor comprises an external tank and an internal tank coaxially positioned within the external tank. A hinged door is provided on the cover that seals the entire body of the reactor. A check valve mechanism located at the top of the internal tank has two openable valve leaflets, each having an area slightly larger than the cross-sectional area of ​​the internal tank and oriented at a downward angle between 20° and 60°. The holding structure of the check valve mechanism is connected to a lifting mechanism, which lifts the check valve when the door is opened, guiding the valve leaflets downward under the effect of gravity. Thus, when the reactor door is opened for the insertion of waste, the internal tank communicates with the outside through the downward-sloping valve leaflets. Furthermore, even when the door is closed, the internal tank is not completely sealed due to the inclined orientation of the valve leaflets.

[0010] The concept of the present invention includes providing a method for safely and simply processing organic waste in such an environment in a closed device under imperfect anaerobic conditions without producing odors, while subjecting the waste to a composting process, specifically a fermentation process by applying a microbial preparation multiple times at a frequency that may lead to the formation of products suitable for soil improvement (soil remediation).

[0011] The concept of the present invention further includes providing a waste treatment apparatus for carrying out the above method, which comprises multiple barriers for maintaining the waste in an imperfect anaerobic environment. [Prior art documents] [Patent Documents]

[0048] In a preferred embodiment, the present invention's method comprises the following steps: - The organic portion of the organic waste, typically consisting of household organic waste, is inserted by the user into the casing of the waste treatment device through the waste treatment device inlet. - Next, the first openable closure means provided at the supply mechanism inlet is opened, the portion of the organic waste enters the supply mechanism located inside the housing through the supply mechanism inlet, wherein the supply mechanism inlet may correspond to or be fitted to the waste treatment device inlet. - Within the supply mechanism, the supply waste is supported or held by a waste holding element until at least the first openable closing means is closed, - The step of closing a first openable closing means.

[0050] In one embodiment, the second openable closure means is opened after the first openable closure means is opened.

[0051] In a very preferred embodiment, the second openable closure means is opened after the first openable closure means is closed.

[0052] - More preferably, after a first openable closure means, which constitutes a barrier between the inside of the supply mechanism and the external environment, is closed, a second openable closure means, which is provided at the outlet of the supply mechanism, is opened.

[0053] - Preferably, the portion of the organic waste supported by the waste holding element is sent to the waste container.

[0054] Preferably, the portion of organic waste placed in the waste holding element is delivered from the supply mechanism to the waste container through an opening in the sealing layer or cover of the removable container or a supply mechanism outlet, preferably a supply mechanism outlet provided in the sealing layer that seals the waste container inlet.

[0055] - In a preferred embodiment, the organic waste stored in the waste container is treated by applying a microbial preparation, preferably a microbiological solution, from time to time (for example, as described above).

[0056] - In a further preferred embodiment, the portion of organic waste added to the waste container is treated by applying a microbiological solution multiple times to the waste stored in the removable sealed waste container, with the removable sealed waste container closed or open, in order to maintain the anaerobic fermentation process of the waste in the waste container using a spraying means located in the supply mechanism.

[0059] After removing the waste container from the enclosure, the fermented organic waste products present in the waste container may be further fermented to obtain a final product suitable for soil improvement.

[0060] definition Fermentation is a metabolic process that causes chemical changes in organic matter through the action of microorganisms. Preferably, fermentation involves the metabolism of carbohydrates via microbial enzymes in an environment isolated from ambient oxygen for at least the majority of the fermentation period. If fermentation takes place in a closed environment that is opened from time to time to add feed, such as a portion of waste feed, then fermentation takes place under anaerobic conditions, specifically incomplete anaerobic conditions, and anaerobic processes are dominant.

[0061] In one embodiment, fermentation, as used herein, relates to food waste fermentation, which includes a process in which microbial activity brings about a desirable change in the food waste and avoids the process of spoilage.

[0062] Suboptimal or imperfect anaerobic fermentation is an anaerobic process that takes place in a closed container for most of the time, where the material being fermented is temporarily exposed to ambient air or oxygen, for example, when waste material is randomly added to the container, but the anaerobic process prevails. Therefore, the aerobic process does not transform the fermentation from its fundamentally anaerobic characteristics. Imperfect anaerobic fermentation is characterized by oxygen-deficient conditions.

[0063] In one embodiment, suboptimal or incomplete anaerobic fermentation occurs when the waste container is in direct contact with the environment, i.e., ambient air (i.e., both the first and second openings, for example, the first openable closure means 41 and the second openable closure means 42 are open) for less than 5%, less than 4%, less than 3%, less than 2%, less than 1%, less than 0.5%, less than 0.25%, or less than 0.1% of the operating time in an indoor environment.

[0064] In one embodiment, the apparatus or device of the present invention is used (opened and closed) irregularly, for example randomly, even if it is used more on certain days or periods than on other days or periods, while suboptimal or incomplete anaerobic fermentation is still maintained.

[0065] As used herein, composting is understood as the process of converting waste material into a material useful for soil improvement. Traditionally, composting has included an aerobic process, as used herein, but this aerobic process is unnecessary in the present invention. Therefore, an anaerobic process, such as a suboptimal or incomplete anaerobic process like fermentation, as used herein, is a preferred variation of composting.

[0066] "At a time" is synonymous with its use herein and means that two events, such as actions, are linked or connected, for example, logically or in a timely manner, and when one event occurs, the other event also occurs or occurs within a limited period, for example, within one hour, within ten minutes, or within a shorter period. In specific modifications, two events occur or two actions are performed via a movable part of the device of the present invention that is in a timely manner. In specific embodiments, two events occur or two actions are performed sequentially, with the second event or action following, preferably immediately following, the first event or action. "At the same time" or "simultaneously" is a specific or preferred modification of "at a time" and suggests a time overlap between the two events or actions.

[0067] As used herein, “sweeping” is understood to mean removal by a series of forceful actions, preferably a single series of forceful actions.

[0068] As used herein, even when used in the singular form, the indefinite articles "a" and "an," and, for example in backreferences, the definite article "the," if the context allows, also include the plural form, that is, unless the context indicates otherwise, they carry the meaning of "one or more."

[0069] The terms “comprise,” “comprising,” and “including” are non-exclusive and should be interpreted here as allowing for the addition or involvement of any further features, method steps, or components to any item that possesses any of the listed features, method steps, or components.

[0070] The expressions “consisting essentially of” or “comprising substantially” should be understood as consisting of essential features, method steps, or components enumerated in a list, e.g., the claims, while permitting the additional inclusion of other features, method steps, or components that do not substantially affect the essential characteristics of the use, method, composition, or other subject matter. It should be understood that “comprise,” “comprising,” or “including” in this specification may be replaced by “consisting essentially of” or “comprising substantially” without adding new matter, where so required. [Modes for carrying out the invention]

[0071] The inventors have created an indoor method for processing organic waste, preferably food waste, with minimal human intervention and low energy consumption, wherein the accumulated organic waste is stored and fermented under anaerobic conditions, specifically incomplete anaerobic conditions characterized by a given oxygen deficiency, for a given fermentation period. This method is useful for processing organic waste, preferably food waste, in indoor human living environments, specifically workplace environments such as offices, kitchens, manufacturing plants, factories, laboratories, workshops, entertainment facilities, schools, etc., specifically in office or home environments where food waste is distributed at random intervals.

[0072] This invention is also useful in providing a platform that can educate and engage users in order to lead to a more environmentally conscious lifestyle.

[0073] In this method, organic waste is processed in a closed or closable device having an inlet that is opened for a limited time to allow the addition of a portion of the organic waste, while the waste is subjected to a composting process, specifically a fermentation process by potentially or preferably multiple applications of a microbial preparation.

[0074] In one embodiment, the microbial preparation is applied, or added, when the device is opened.

[0075] In further embodiments, the microbial preparation is applied, or added, periodically, for example, once or multiple times a day.

[0076] In alternative embodiments, the microbial preparation is applied according to the requirements of the fermentation process, for example, according to one or more measurement parameters. This embodiment is based on the state of the material to be fermented and when the fermentation requires the addition of a portion (or amount) of the microbial preparation. If the addition depends on a measurement parameter, such a parameter may be, for example, temperature, which may be measured, for example, in a removable waste container or upstream in the supply mechanism.

[0077] In any case, the microbial preparation is applied at a frequency that maintains anaerobic conditions where anaerobic processes are dominant, i.e., at least incomplete anaerobic conditions, or at a frequency that induces fermentation in a direction that may lead to the formation of products suitable for soil improvement (soil remediation). In one embodiment, the result is a partially fermented product that can be further fermented into materials directly applicable to soil remediation in an optionally closed (anaerobic) environment.

[0078] As a result, - The environment is disturbed at random time intervals. - Organic waste is collected in an environment where it is formed randomly, for example, in an office environment. - Users may supply the device at any time. Any type of organic waste, such as plant waste, meat waste, or processed food residues with varying moisture content, may be added, composted, and preferably fermented. - In an indoor environment, contact with the surrounding air is minimized, resulting in incomplete anaerobic conditions. - Fermentation is initiated and maintained throughout the fermentation period by adding a microbial preparation containing various classifications of microorganisms or microbial consortia.

[0079] The present invention provides a solution for indoor treatment of organic waste, such as food waste. The present invention relates to a fermentation method used as an alternative to conventional composting. The inventors have developed a method and device for processing organic waste, which is operablely linked to the introduction of organic waste into a device, and further, in a controlled environment to avoid harmful aerobic processes, such as decomposition, the organic waste can be sustainably collected and, if necessary, further manipulated to be converted into a resource beneficial to the soil, preferably a material containing components beneficial to soil improvement, such as soil fertilizer, for a sufficiently long period of time. The controlled environment is anaerobic, but is not necessarily incomplete, taking into account and depending on the frequency of addition of organic waste.

[0080] The present invention provides an easy-to-use, standalone, automated indoor composting solution that combines energy efficiency and natural methods similar to a bokashi system with significantly less human intervention, suitable for environments where users do not wish to be involved in the process. This technology further provides consumers with the data necessary to evaluate the environmental impact or benefits associated with composting. In this way, the present invention arrives at a solution that requires minimal energy and human input during use, yet is still safe and odorless enough to be used in indoor environments, such as office, workplace, or home environments.

[0081] The present invention will be described below through specific exemplary embodiments.

[0082] The device processes and optionally measures (and potentially processes based on the measured parameters) specific parameters of food waste introduced through an opening, particularly a waste holding element that is kept clean by either surface treatment and / or a mechanical cleaning procedure.

[0083] Food waste is introduced into a sealed container separate from the other components of this device. To keep the inside of the container as isolated as possible from the outside, ensuring an imperfect anaerobic environment with insufficient oxygen, while also preventing moisture and odor leakage and maintaining the internal structure, the organic waste enters the removable container through an opening or the outlet of the supply mechanism.

[0084] In preferred embodiments, the maximum mass of the waste to be treated is 10 to 100 kg, preferably 15 to 50 kg, more preferably 20 to 25 kg, and is stored in a container having a volume of 10 to 100 l, preferably 20 to 60 l, more preferably 35 to 40 l.

[0085] The storage and fermentation period before removing the container is typically 1 to 8 weeks, preferably 1 to 4 weeks, and preferably 1 to 2 weeks.

[0086] In the first step, the waste feed is inserted by the user into the feeding mechanism of the waste treatment device. The feeding mechanism is provided with an openable feeding mechanism inlet (optionally, an openable feeding mechanism that can be activated automatically) that communicates with the outside of the waste treatment device, and an openable feeding mechanism outlet that communicates with the organic waste container housed in the waste treatment device. The feeding mechanism constitutes a sub-chamber or lock gate that isolates the waste container from the surrounding air.

[0087] In one embodiment, both the inlet and outlet of the supply mechanism are closed in their stationary positions.

[0088] In a further preferred step, after the inlet of the feeding mechanism is closed following the insertion of the waste material, a microbiological solution containing anaerobic bacilli and anaerobic bacilli nutrients (in particularly preferred embodiments, EM-BIO1 base solution and EM-BIO1 activated microbiological preparations may be used, which may be purchased, for example, from Multicraft Productions-und Handels GmbH) is applied to the waste material by a spraying means provided in the feeding mechanism to initiate the fermentation process of the waste material. The volume of solution applied is preferably adjusted according to the mass of the inserted waste material, measured by a sensor integrated into the feeding mechanism.

[0089] In particularly preferred embodiments, "effective microorganisms (EM)," which can also be applied in composting techniques, are used. The mixed culture called EM contains beneficial microorganisms such as naturally occurring lactobacilli, actinomycetes, purple non-sulfur bacteria, and yeasts. Organic matter such as molasses is added during operation. Modifications may include other products such as foliage.

[0090] Waste disposal is typically carried out in closed bioreactors or uncleaved piles to create anaerobic conditions and suppress pathogens in the fermented compost. Therefore, lactic acid fermentation is the primary method of disposal.

[0091] In the next step, the outlet of the supply mechanism opens, and the waste material is delivered through the outlet of the supply mechanism to an organic waste container.

[0092] Preferably, removal may be by force, such as gravity or sweeping. As used herein, “sweeping” is understood to mean removal by a series of forceful measures, preferably a single series of forceful measures.

[0093] The waste material subsequently inserted may form a deposit at the bottom of the waste container. In one embodiment, the top surface of the deposit is sprayed with a predetermined volume of a microbial preparation (e.g., a microbiological solution) by a spray nozzle of the feeding mechanism in order to cover the top surface with an additional protective microbiological film layer. After spraying the solution, the outlet of the feeding mechanism and / or the opening of the sealed (covered) waste container are closed again. This outlet and opening may be in the same location or in different locations. This mechanical separation contributes to the development of an anaerobic environment within the waste container. In parallel, the internal parameters of the waste treatment device may be measured continuously in further steps. For example, a weight sensor and a humidity sensor may continuously measure the mass and humidity level of the organic waste stored in the waste container, and a temperature sensor may monitor the temperature inside the waste treatment device, either outside or inside the waste container. A preferred range for the target temperature value is 20-35°C. For example, the level of waste stored in the container may be monitored by a camera or by gravimetric measurement.

[0094] Moisture (water) can be discharged either through a water-absorbing layer placed at the bottom of the waste container, or through a moisture storage compartment formed within the container as part of the double-walled structure of the waste container.

[0095] In a preferred embodiment, moisture is absorbed by an absorbent material placed in the waste container.

[0096] Preferably, the absorbent may be able to work synergistically with the waste material stored in the waste container during operation. Alternatively, the stacked absorbent may be stacked at the bottom of the waste container having a double-walled structure, i.e., at the top of the moisture storage compartment.

[0097] If the measured humidity level is outside the target interval suitable for the fermentation process, a dry material such as powder may be applied to the waste material. For this purpose, a second spraying means, such as a spray nozzle (or a group of nozzles), may be placed on top of the waste container.

[0098] Temperature and visual data within the waste treatment device may be recorded by a camera. This method provides an indicator of the activity of anaerobic bacilli in the waste container, thereby providing an indicator of the competitive advantage of anaerobic bacilli over other competing microorganisms that are unfavorable to fermentation. These competing microorganisms are present on the surface of the waste material being inserted and in the surrounding air, and can be a cause of decay or mold.

[0099] For example, a temperature rise exceeding the target interval reflects the initiation of unwanted spoilage. In this case, additional amounts of microbiological solution and / or dry material are added to the stored waste material to return the fermentation to its equilibrium. In one embodiment, the container is removed and replaced.

[0100] The product is a stable fermentation intermediate product suitable for further conversion into soil improvement material. The fermentation stage depends on the storage period in the waste treatment facility, which is typically 10 to 15 days.

[0101] The waste treatment device of the present invention will be described below as an example with reference to the attached drawings. [Brief explanation of the drawing]

[Figure 3D] This is a front perspective top view of a drawer for a supply mechanism having a sweeping element according to a preferred embodiment of a waste treatment apparatus according to the present invention, wherein the drawer is in a closed inclined position and the sweeping element is in a sweeping position. [Figure 4A] This is a schematic cross-sectional view of the waste holding element of the open supply mechanism, which is equipped with a transport means, when inserting the waste portion into the supply mechanism during operation. [Figure 4B] This is a schematic cross-sectional view of a waste holding element in a closed supply mechanism, which is equipped with a transport means for delivering the waste portion from the waste holding element towards the outlet of the supply mechanism during operation.

[0103] cabinet As shown in Figure 1, the waste treatment device comprises a housing 1, which is, for example, spherical, and a waste treatment device inlet 11 provided in the housing 1 for inserting organic waste. The housing 1 may comprise two regions: a housing base 12 configured to rest on the floor, and a housing top 13. For ergonomic use, the waste treatment device inlet 11 may preferably be located in the housing top 13, and the housing base 12 may be raised from the floor by legs 14.

[0104] A waste container 2 having a waste container inlet 21 is detachably installed inside the housing 1 for storing organic waste. The detachable waste container 2 may be maintained in position relative to the housing 1 by a retaining element 121 fixed to, for example, the inner wall of the housing base 12.

[0105] The housing 1 may be openable, preferably along a surface that physically separates the housing base 12 from the housing top 13, for the purpose of removing the waste container 2 and for maintenance. The housing base 12 and the housing top 13 are preferably connected by hinges and a closing latch. The housing 10 may also be openable by an additional lift-up lid, which is not shown in Figure 1.

[0106] supply mechanism As shown in Figure 1, the waste treatment device includes a supply mechanism 3 located within the housing 1 between the waste treatment device inlet 11 and the waste container inlet 21 to deliver the organic waste portion inserted through the waste treatment device inlet 11 to the waste container 2. The supply mechanism also isolates the waste container inlet 21 from the waste treatment device inlet 11. The inside of the waste container is isolated from the outside as much as possible to ensure an imperfect anaerobic environment with oxygen deficiency, while preventing moisture and odor leakage and maintaining the internal environment.

[0107] The supply mechanism 3 has a supply mechanism inlet 31 for inserting the waste portion into the supply mechanism 3. The supply mechanism inlet 31 is provided with a first openable closure means 41 which constitutes a barrier between the inside of the supply mechanism 3 and the waste treatment device inlet 11, specifically a first barrier between the environment outside the waste treatment device and the waste container inlet 21. As can be seen in Figure 1, the supply mechanism inlet 31 may correspond to or fit into the waste treatment device inlet 11, and therefore the first openable closure means 41 may also close the waste treatment device inlet 11. Specific embodiments of the first openable closure means 41 are further described below in Figures 3A to 3C.

[0108] The supply mechanism 3 receives the inserted waste portion. forThe system includes a waste holding element 5. The useful surface of the waste holding element 5 may be coated with a hydrophobic or water-repellent layer to facilitate the transfer of waste portions to the waste container 2 at a later stage. The waste holding element 5 may be equipped with sensors for sensing the parameters of the inserted waste portions. For example, weighing sensors may be placed on the waste holding element 5 to weigh each waste portion individually. Alternatively, such weighing sensors may also be provided on the holding element 121. As a result, it may be possible to monitor the total mass of organic waste inserted or stored in the waste container 2.

[0109] The supply mechanism 3 includes a spraying means 6 for treating the waste feed by applying a microbiological solution. The spraying means 6 may be located above the waste container inlet 21. The spraying means 6 may also be located above the supply mechanism outlet 32. Furthermore, the spraying means 6 may be located upstream, directed towards the waste holding element 5 to treat the waste portion individually before it enters the waste container 2, for example. Furthermore, the spraying means may be connected to the waste container 2 to add a drying material to the stored waste material.

[0110] Ultimately, supply mechanism 3 is supplied from supply mechanism 3. Removable It has a supply mechanism outlet 32 ​​provided in the sealing layer 7 to allow the waste portion to pass into the waste container 2. The sealing layer 7 is Removable waste container 2 The entire protruding surface of the waste container inlet 21 is sealed. Similar to the supply mechanism inlet 31, the supply mechanism outlet 32 ​​is provided with a second openable closure means 42 that closes the supply mechanism outlet 32 ​​over its entire area. Consequently, the sealing layer 7 and the second openable closure means 42 constitute a second barrier between the environment outside the waste treatment device and the waste container inlet 21.

[0111] The first openable closure means 41 and the second openable closure means 42, which act as barriers, contribute to ensuring an imperfect anaerobic environment with oxygen deficiency within the removable waste container 2.

[0112] Sealed waste containers Figures 2A, 2B, and 2C illustrate a preferred embodiment of a removable waste container 2 having a sealing layer 7, with the supply mechanism outlet 32 ​​and the second openable closure means 42 in the closed and open states, respectively. The waste container 2 may typically have a cylindrical or flared cylindrical shape. The sealing layer 7 is Removable waste container 2 The sealing layer 7 may be a plate positioned in sealed contact with the waste container inlet 21 and its circumference. The supply mechanism outlet 32 ​​positioned in the sealing layer 7 may have a smaller area than the waste container inlet 21. The sealing layer 7 may also be provided with further through-holes 71, 72 with seals for positioning sensors configured to monitor the internal space of the waste container 2, or for connecting spraying means 6 or conduits for spraying means 6. As shown in Figure 2B, the sealing layer 7 may be provided with three spraying means 6, each provided in a hole 71, for suitable dispersal of microbiological preparations within the waste container 2. The second openable closure means 42 may consist of two complementary shaped wings 421 and 422, for example, rotatably connected to the sealing layer 7 on the side adjacent to or opposite the waste container inlet 21, and adjoining each other along their respective contact surfaces when closed. The rotation axes of the blades 421 and 422 may be perpendicular to the supply mechanism outlet 32, and thus the blades 421 and 422 may be configured to rotate in a plane parallel to the supply mechanism outlet 32 ​​between a closed state and an open state defined by an opening angle α. The plane motion trajectory prevents the second openable closure means 42 from coming into contact with the waste stored in the waste container 2 and thereby from being contaminated by the waste stored in the waste container 2. In addition, the plane motion trajectory allows for space saving in either the supply mechanism or the waste container 2, and thus contributes to a compact design of the waste treatment device. In other embodiments, the second openable closure means 42 may consist of one single blade or a plurality of complementary shaped blades. At least one blade may be slidably connected to the sealing layer 7.

[0113] The first openable / closed means 41 and the second openable / closed means 42 may have their own manual or electrical drive means.

[0114] Alternatively, the second openable-close means 42 may be connected to the first openable-close means 41 by an energy storage mechanism, which stores the kinetic energy of the first close means 41 to activate the second close means 42 in the next step.

[0115] The waste container 2 may have a compartment for collecting moisture (humidity) from the waste. In one embodiment, the waste container 2 may have a moisture storage compartment at its bottom, formed within the container as a double-wall structure for collecting moisture. Preferably, the walls are horizontal. One of the walls, for example, the upper wall, is in contact with the organic waste. Preferably, the double-wall structure has one or more holes (e.g., perforated) in the wall in contact with the organic waste to allow moisture to drain into the compartment. Preferably, the perforation allows moisture to move in only one direction so as to limit moisture from re-entering the main container. Preferably, the moisture compartment may be drained separately from the main compartment of the container after the container has been removed from the device. In one embodiment, the moisture collection compartment may be removed in a separate step.

[0116] Alternatively, the removable sealed waste container 2 may be equipped with an absorbent to absorb moisture from the waste stored inside the container. Alternatively, moisture is not discharged but simply absorbed by an absorbent layered at the bottom of the waste container 2. The absorbent is preferably, for example, hemp, straw, hay, sawdust, crushed corn cobs, wood flakes, etc., and preferably hemp or wood flakes, and may be an absorbent suitable for addition to soil. Preferably, the absorbent may be able to work in cooperation with or synergistically with the waste material stored inside the waste container 2 during operation. Alternatively, the layered absorbent may be layered at the bottom of the waste container 2 having a double-wall structure, i.e., at the top of the moisture storage compartment described above.

[0117] drawer As shown in Figures 3A to 3D, the first openable closure means 41 and the waste holding element 5 may be part of a slidable and tiltable drawer 9. The drawer 9 may be slidable and tiltable to the housing 1 via a guide system 95. The front of the drawer 9 may form the first openable closure means 41. The tray of the drawer 9 may form the waste holding element 5. The rear of the drawer 9 may be exposed to allow passage of waste placed in the waste holding element 5.

[0118] Alternatively, the drawer 9 may be a closed cassette with a closable opening to allow the waste portion to pass towards the waste container 2.

[0119] The guide system 95 is configured to guide the drawer 9 between a horizontal starting position and an inclined ending position relative to the supply mechanism. The guide system 95 may include guide rails and / or cam slots for receiving the corresponding cam and / or actuator of the drawer 9. The cam slots of the guide system 95 may have at least downwardly curved portions and at least horizontal portions, for example in the form of a switch curve, to provide sliding and inclined motion of the waste portion to place (or deliver or send) the waste portion into the container.

[0120] Sweeping element The supply mechanism 3 may include a sweeping element 55 for cleaning the waste holding element 5. The sweeping element 55 may have an outline that is at least partially complementary to the waste holding surface of the waste holding element 5. The sweeping element 55 may be rotatably connected to the supply mechanism 3, for example, to the guide system 95 of the drawer 9. Thus, the sweeping element 55 is configured to efficiently clean the waste holding surface of the waste holding element 5.

[0121] As shown in Figures 4A to 4B, in an alternative embodiment, the waste holding element 5 may be provided with a transport means 8 for transporting the waste portion toward the waste container 2. The transport means 8 may be connected to an electronic or manual actuation means.

[0122] The configuration of the sealed waste container 2 and the waste holding element 5 of the supply mechanism 3 prevents the placed waste from scattering within the internal space of the waste treatment device.

[0123] Control, sensing The waste treatment device may be equipped with sensors for measuring parameters within the supply mechanism 3 and waste container 2, such as a weighing sensor, humidity sensor, pH measuring means, temperature sensor, and camera.

[0124] The waste treatment device may include a control unit 15 for receiving, storing, and processing measurement data from sensors preferably located in the supply mechanism 3, and for controlling the electrically operated parts of the waste treatment device. However, to ensure minimal energy consumption, manual actuation means and kinetic energy storage means are preferred for operation. A user interface panel for communicating with the control unit. but It may be placed in enclosure 1.

[0125] The operation of the waste treatment apparatus according to the present invention will be described below with reference to the drawings.

[0126] - A portion of the organic waste, typically consisting of household organic waste, is inserted by the user into the waste treatment device housing 1 through the waste treatment device inlet 11.

[0127] - Next, upon opening the first openable closure means 41 provided at the supply mechanism inlet 31, that portion of the organic waste enters the supply mechanism 3 located within the housing 1 through the supply mechanism inlet 31. The first openable closure means 41 may be opened manually or automatically operated by an actuator. Preferably, the supply mechanism inlet 31 may correspond to or be fitted into the waste treatment device inlet 11. In this case, the supply mechanism inlet 31 and the waste treatment device inlet 11 may be opened in a single step by opening the first openable closure means 41. The waste portion inserted into the supply mechanism 3 is supported by the waste holding element 5.

[0128] In a preferred embodiment, as shown in Figures 3A to 3D, the first openable / closed means 41 and the waste holding element 5 may form a slidable and pivotable front and tray of the drawer 9, respectively. As shown in Figure 3A, the open position of the drawer 9 is horizontal with respect to the supply mechanism. The user may then place the waste portion into the tray of the drawer.

[0129] As shown in Figure 3B, the drawer 9 is then slid horizontally along the guide means 95, for example along the horizontal portion of the cam slot, relative to the supply mechanism 3, which is operated manually or electrically, until the drawer 9 reaches the horizontal closed position. As a result, the first openable closing means 41, which is part of the drawer 9 in this case, is in the closed position. The mass of the waste portion may be measured by a weighing sensor located in the waste holding element 5. When a portion of the organic waste is placed in the waste holding element 5 of the supply mechanism 3, which is the tray of the drawer 9 as shown in Figure 3A, it may be treated by applying a microbiological solution with a spraying means 6.

[0130] Within the supply mechanism 3, a portion of the organic waste is supported by a waste holding element 5 in a horizontal position until at least the first openable closure means 41 is closed. A first microbial treatment and some measurements of the waste portion parameters are performed on the waste portion in the supported position on the waste holding element 5. The supply mechanism 3, closed by the first openable closure means 41 and the second openable closure means 42, constitutes a closed sub-chamber for the waste feed upstream of the waste container 2. The sub-chamber supports an incomplete anaerobic environment and oxygen-deficient conditions within the internal space of the waste container 2.

[0131] - Preferably, after the first openable closing means 41, which constitutes a barrier between the inside of the supply mechanism 3 and the external environment, is closed, the second openable closing means 42 provided at the outlet 32 ​​of the supply mechanism opens, and the opening is driven by a manual actuation means, an electrical actuation means, or via a kinetic energy storage mechanism. 。

[0132] In one embodiment, the second openable closing means 42, provided at the outlet 32 ​​of the supply mechanism, is closed after the first openable closing means 41, which constitutes a barrier between the inside of the supply mechanism 3 and the external environment, is closed. In a preferred embodiment, the first openable closing means 41 is closed before the second openable closing means 42 is closed, more preferably before the second openable closing means 42 is opened.

[0133] In specific embodiments, opening and closing are driven by manual or electrical means, or via a kinetic energy storage mechanism.

[0134] - As shown in Figure 2C, in a preferred embodiment, the blades 421 and 422 may rotate until they reach an open state defined by the opening angle α.

[0135] - It should be noted that in order to maintain the separation of the waste container 2 from the external environment by at least one layer, namely the first openable closure means 41 or the second openable closure means 42 of the sealing layer 7, or both, the first openable closure means 41 and the second openable closure means 42 are never in the open position at the same time.

[0136] - It should also be noted that a separate waste holding element 5, positioned upstream of the second openable closure means 42 of the sealing layer 7, prevents cross-contamination between the waste stored in the waste container 2 and the currently placed waste portion.

[0137] - Subsequently, a portion of the organic waste placed in the waste holding element 5 may be delivered from the supply mechanism 3 to the removable waste container 2 through the supply mechanism outlet 32 ​​provided in the sealed layer 7.

[0138] - Therefore, as shown in Figure 3C, the drawer 9 may be pivoted so that the tray is tilted from its initial horizontal position to an inclined position oriented downward toward the supply mechanism outlet 32. The waste holding element 5 may be tilted by an actuator, or by displacing the guided cam from the horizontal portion to the downwardly curved portion of the guide means 95, either by an actuator or via a switch-curved configuration of the guide means 95. In this case, the feed may be operated by gravity. The waste portion slides on the hydrophobic or hydrophobic coating of the waste holding element 5. As shown in Figure 3D, the sweeping element 55 may sweep the waste holding surface of the waste holding element 5 to push the waste portion toward the supply mechanism outlet 32. The waste holding element 5 is then freed of waste.

[0139] - If the waste holding element 5 is provided with a transport means 8 as shown in Figures 4A to 4B, the first openable closure means 41 may be pulled out together with the waste holding element 5 until the waste portion is inserted into the transport means 8 through the supply mechanism inlet 31. The first openable closure means 41 and the waste holding element 5 may be pushed back together with the waste portion to the closed state shown in Figure 4B. After the first openable closure means 41 is closed, the waste portion is transported by the transport means 8 to the supply mechanism outlet 32 ​​and thus transported towards the waste container 2 located below by simply operating the transport means 8.

[0140] - After the waste material enters the waste container through the supply mechanism 32 and the waste container inlet 21, the second openable closing means 42 is closed. Subsequently inserted waste material may form a deposit at the bottom of the waste container 2. Parameters of the waste material stored in the waste container 2 or parameters within the waste container 2 may be monitored discretely or continuously as a function of time using sensors such as humidity sensors, pH measuring means, temperature sensors, and cameras located in holes 71, 72. The measurement data is sent to the control unit to Therefore, it is received, stored, and processed.

[0141] - The waste portion inserted thereafter may form a deposit at the bottom of the waste container 2. In order to cover its upper surface with a protective microbiological film layer, the upper surface of the deposit is sprayed with a predetermined volume of a microbial preparation (e.g., a microbiological solution) by the spraying means 6 of the supply mechanism 3.

[0142] - Treatment may be carried out by a spraying means 6 located above the supply mechanism outlet 32 ​​when the second openable closure means 42 is open, or by a spraying means 6 connected to the area of ​​the waste container inlet 21, the opening 71 or opening 72 of the sealing layer 7 when the supply mechanism outlet 32 ​​is closed. As described above, the organic waste portion may also be additionally treated upstream when it is placed in the waste holding element 5 of the supply mechanism 3.

[0143] In any case, the treatment action may be adapted to the monitored parameters, specifically pH, humidity, and waste mass.

[0144] - The user is the user interface panel. of Through this, measurement data and treatment data can be accessed.

[0145] - Since moisture can lead to the development of competing microorganisms unfavorable to fermentation, it is preferable to keep the waste stored in the waste container 2 as dry as possible. Therefore, moisture in the waste material stored in the waste container 2 may be absorbed, for example, by absorbents layered at the bottom of the waste container 2. Alternatively, moisture may be collected by a compartment provided at the bottom of the waste container 2. The absorbent layer may work synergistically with the waste material stored in the waste container 2. In another embodiment, moisture may be collected by absorbents layered in the waste container in conjunction with a moisture storage compartment formed within the container. If the measured humidity level is outside the target interval suitable for the fermentation process, a dry material such as powder may be applied to the waste material through an additional spraying means. This solution minimizes user intervention because the collected liquid does not need to be separately removed during the complete collection cycle.

[0146] - A portion of the organic waste is maintained in a removable, sealed waste container 2 under incomplete anaerobic and oxygen-deficient conditions for an incomplete anaerobic fermentation period. In parallel, additional portions of the organic waste may be placed in the waste treatment device 2 at random intervals. User Interface Panel teeth Further information regarding advancements in the composting process may be provided to users.

[0147] - Compression or agitation is not required within the waste container.

[0148] - After the incomplete anaerobic fermentation period, the waste container 2 containing the fermented organic waste product is removed from the enclosure 1. The waste container 2 may also be removed together with the sealing layer 7. The waste container 2 may also be removed separately and sealed in the disposable layer. The enclosure 1 may be opened by separating the top of the enclosure 13 from the base of the enclosure 12.

[0149] - After removing the waste container 2 from the housing 1, the fermented organic waste products present in the sealed waste container 2 may be further fermented to obtain a final product suitable for soil improvement.

[0150] In a preferred embodiment, the device enables a multi-stage indoor method for processing and disposing of organic waste, the device comprising a supply mechanism 3 which preferably includes a drawer 9 that can be opened while the (sealed or sealable) waste container 2 remains closed and thus isolated.

[0151] Preferably, the supply mechanism 3 is at a suitable height for user operation and mitigates the risk of leakage and item bounce-back that may occur if dropped from a greater height.

[0152] Preferably, the waste container 2 is sealed by a sealing layer 7, i.e., the surface or lid of the waste container.

[0153] As a further step when the user closes the first openable closing means 41 (of the supply mechanism inlet 31), the organic waste "part" is preferably sent to the waste container 2 by the guide system 95.

[0154] The waste is fed into a sealable waste container via a second openable closure means 42 that opens and closes synchronously with the drawer, preferably via two complementary shaped wings 421 and 422 that are rotatably connected to the sealing layer 7 on the side adjacent to or opposite the waste container inlet 21 and are adjacent to each other along their respective contact surfaces when closed, by gravity-assisted discharge of the supply mechanism 3, preferably the “drawer” 9. The function of the wings 421 and 422 may be as described in the examples.

[0155] Preferably, in the case of a supply mechanism 3 comprising a drawer 9, an additional sweeping element 55 may sweep the surface of the waste holding element 5, preferably the surface of the “drawer” 9, to remove dirt and prepare it for the next user interaction (i.e., opening the drawer). This can be further enhanced later if an anti-stick surface treatment is applied to the waste holding element 5, preferably the “drawer” 9.

[0156] It should be noted that when the drawer is open, the container containing the remaining waste is closed, and the container is only opened when the closed drawer blocks the airflow path from the waste area to the outside, thereby maintaining the system in a suboptimal anaerobic state and preferably keeping it as odorless as possible.

[0157] In this way, a) the area where the user places waste is always clean, b) there is no clear path for air to enter or leave the system, and c) the aerobic decomposition of the introduced organic waste is minimized by the lack of air introduction, and as a result, the conditions inside waste container 2 are kept as oxygen-deficient as possible.

[0158] Subsequently, the container can be emptied by removing the sealed waste container 2, thereby further reducing the possibility of undesirable odors entering the environment.

[0159] The operation of the "wiping machine" device, and the opening of the second openable closing means 42 that provides a seal to the sealed waste container, can be mechanically or electronically synchronized with the closing and opening of the supply mechanism 3, preferably the drawer 9.

[0160] The device of the present invention has an efficient and ergonomic design, enabling the method to be performed in a suitable environment with minimal user intervention and minimal energy consumption. The device of the present invention ensures the collection and storage of organic waste in imperfect anaerobic environments with oxygen deficiency. [Explanation of symbols]
