A flushable biodegradable pouch having water-dispersible fibers along at least a portion of the outer surface of the pouch's cover layer provided with a water-soluble hydrophilic coating. The pouch's cover layer is water-disintegratable, and the water-soluble hydrophilic coating is a lubricating agent capable of becoming slippery when exposed to water and, upon subsequent drying, again becoming water-soluble upon re-exposure to water. As such, the hydrophilic coating serves as a rewettable, redesolving lubricating agent.

A biodegradable film formable into biodegradable bags includes the blended product of polylactic acid and a suitable biodegradable polymeric resin. The blended product includes from about 5% to about 50% by weight polylactic acid.

A toilet that does not require water for use, which may be used in the home or which may be portable for use at locations outside the home, having a disposable, biodegradable bag for catching and storing human waste for disposal, and a method for disposing of said biodegradable bag.

A device and method for collecting organic waste is disclosed. The invention comprises a biodegradable bag that hangs inside a rigid container covered by a perforated lid. A filter lines the inside of the lid which rests on the rim of the rigid container. The biodegradable bag is secured onto an annular flange by means of a retaining band. The flange, together with the biodegradable bag, sits on the shoulder on the inside of the rigid container so that the biodegradable bag hangs from the flange leaving a cavity inside the rigid container between the biodegradable bag and the walls of the rigid container. The flange has a handle to pull the biodegradable bag out. The biodegradable bag aids in composting of the organic waste as it is permeable to both air and water and provides the largest possible surface area of any waste container to aerate the organic waste.

A biodegradable odor and moisture absorbing article and system includes a biodegradable odor removing agent insert formed as a pouch for use removing odors and moisture from articles such as a bag, enclosure, or environment surrounding the person. The biodegradable pouch includes activated bamboo charcoal enclosed with a 100% breathable fabric (linen or hemp. The system includes an inner-facing layer of a dry touch breathable material such as fabric that wicks moisture into the pouch and an outer layer comprising a waterproof material or barrier (e.g. 100% vinyl backed polyester backing) configured to face the moisture such as a bag, enclosure, or environment surrounding the person. The article eliminates odor by the adsorption process when the pouch is inserted in the bag, enclosure, or environment surrounding the person.

The present invention is a biodegradable bag used as a liner for a grass-catcher bag of a lawnmower. The bag is releasably secured to the grass-catcher bag using a clip. A compost accelerant is placed inside the bag to speed the decomposition of the bag and the lawn waste contained inside. Once filled with lawn waste, the bag may be closed using a drawstring cinch-top and then placed in a compost heap for decomposition. The bag is adapted for use with grass-catcher bags for side-discharge and rear-discharge lawnmowers.

The present invention provides a bag made of a non-woven biodegradable material comprising a body portion having at least one side wall and a bottom joined together to define a storage space therebetween and an opening at the top of the body portion, wherein the bag is biodegradable and non-toxic to the environment

This invention is a device for irrigating tree seedlings and other small plants, to ensure that said plants stay moist in the critical few weeks following their planting. The device uses a bag, approximately 1 gallon capacity, constructed of biodegradable plastic, such as cornstarch, which slowly degrades into the soil so as to not leave residue in the planting field. The bag has a top filling opening with an adhesive sealing flap, and contains a multi-layered disk which acts as a passive valve which permits the slow drip-release of water from the bag over a 2-3 week period following planting. The multi-layered disk is made of two layers of thin plastic, a layer of special laboratory filter paper, and a layer of adhesive-sided gasket material which attaches said disk to said biodegradable bag. The design of the hole patterns in the layers of the disk, and the assembly and precise compression of said layers during manufacture, result in a device that produces the desired slow-release flow characteristics.

A novel biodegradable label for use in connection with tubular biodegradable or compostable tubular bags for packing fresh produce. The label consists of paper printed with UV-cured or water based ink on one side of the label and biodegradable lamination on the other side of the label. The label is attached to the biodegradable bag by using heat of 175° C. from all of its four sides and the tubular bag is closed from its open ends by sealing the bag in between of two labels preferably by using heat.

The invention discloses a biodegradable packing bag. The formula comprises chitosan, cellulose, starch, an initiator and a coupling agent. A preparation method of the biodegradable packing bag comprises the following steps: freezing a sodium hydroxide aqueous solution with the mass fraction being 10-20% for 2-3 hours at the temperature of 12-16 DEG C; adding the chitosan and the cellulose, intensively stirring for 5-15 min at high speed, and then adding the starch and uniformly stirring to form a pretreated solution; washing and drying the pretreated solution and then successively adding the initiator and the coupling agent; after mixing the components uniformly, plasticizing and extruding the mixture through an extruder; and carrying out pelleting and film blowing on an extruded materialto obtain the biodegradable packing bag. A natural high polymer material is used as a raw material, the prepared packing bag can be completely biodegraded, and does not pollute the environment, by compounding of the cellulose and the chitosan, the strength of extension of the packing bag is further improved, the toughness of the packing bag is improved, and the problem that the packing bag is easyto crack is solved.

To aid in the spontaneous opening of closed garbage bags deposited in landfills, a biodegradable bag tie made from plant sources is described. The preparation of the tie material includes hydrolysis with an acidic, enzymatic, or basic aqueous solution, combined with microwave exposure, to make the strip amenable to rapid digestion by microorganisms indigenous to landfill environments. The strips may then be tied by knotting around the open end of the polyethylene garbage bag or by joining the two ends of the strip with double-sided adhesive tape. In this way, the closed tie is digested soon after deposition of the bag in a landfill, thereby also exposing its contents to local aerobic bacteria and fungi.

The invention discloses an ecological cultivation method of Manicure finger grapes, and belongs to the technical field of grape planting. The method comprises the steps of soil improving, seedling growing treatment, transplanting and field planting, shed erecting and film covering, top application and watering, tip fixing and clipping, flower and fruit shaping, fruit bagging, bag removing and quality improving, dormancy promoting and the like. According to the ecological cultivation method of the Manicure finger grapes, aiming at the growing characteristics and nutritional requirements of theManicure finger grapes, soil is improved, decomposed organic fertilizer and microelements are additionally applied, the top application is reasonably carried out, and plant dormancy is promoted in advance, so that chemical fertilizer use amount is reduced. When seedling growing treatment is carried out, root hairs are disinfected and sterilized, microorganisms for sterilization are added into fertilizer for transplanting and field planting, a rain shelter is adopted to replace outdoor planting and greenhouse planting, the microelements are regularly sprayed, and biodegradable bags produced bymass production of a factory are used at the same time, so that resistance to diseases and pests of the grapes is improved, and conditions of occurence of plant diseases and insect pests is reduced, thereby reducing the use of pesticides. Therefore, environmental pollution is reduced, and the environment-friendly grapes are produced.
