Problems solved by technology

[0008] In the waste utilization methods described above, high-cost equipment technology is still necessary to carry out aerobic hydrolysis, so similar equipment requires a large space on the one hand and relatively high costs on the other hand
Therefore large quantities of highly polluting exhaust gases are generated and complex and expensive gas cleaning and incineration must be carried out according to 30th BIMSCHV

Embodiment Construction

[0044] Figure 1 exemplarily shows the rationale for the minimum required equipment for the boiling extraction process to treat organically contaminated waste such as, for example, residual waste, food boxes, waste from the food industry, vegetables and other recyclables Organic waste, sewage and fermentation sludge, biological residues such as mash from beverage production.

[0045] Organic pollutants 1 are supplied to reactor 2 and diluted with fresh water or circulating fluid 6 . The waste suspension 74 is mixed with the liquid with the help of the stirring device 8 and transported. Heat is provided by heating jacket 4 to reach the boiling point temperature.

[0046] In order to accelerate the heat treatment, it is also possible to continuously introduce pressurized steam 38 directly into the suspension 74 and / or via an upstream heating belt not shown in detail.

[0047] The major part of this residual waste consists mostly of short-chain compounds adsorbed onto the surfac...

Abstract

The invention relates to a method for processing unrecyclable trash and other organic-laden waste products and to a processing plant for said trash. According to the invention, a waste product containing organic components is heated in a reactor under vacuum to the boiling temperature of water so that the membranes of water-bearing cell structures are destroyed and the heavily organic-laden cell water can be removed along with the exhaust vapors.

Description

technical field [0001] The invention relates to a method of waste treatment according to claim 1 , and a treatment plant for residual waste according to independent claim 13 . Background technique [0002] Waste utilization, such as utilization of domestic waste, industrial waste, organic waste, etc., is regulated by the regulations of the waste ordinance and waste treatment is preferably carried out as far as possible. Waste regulations basically apply to any holder of waste as well as public entities responsible for waste disposal, such as cities and community cleaning companies. The waste regulations as well as the German Federal Environmental Protection Ordinance (BIMSCHV) specify that waste must be immediately collected, transported and stored, and disposed of by means of non-prevented waste utilization options. In order to comply with this utilization responsibility, waste utilization is beneficial to society from the viewpoint of materials and energy. [0003] Mater...
