  • the invention relates to a plant for the simultaneous recycling of structurally poor and structurally rich organic waste, with which the most varied batches of waste can be processed and which can be flexibly adapted to the quantities and types of waste accumulating.
  • the invention also relates to a corresponding recycling process and a new biogas plant for the two-stage fermentation of organic waste materials, which is either part of the above plant or can also be used independently of the above-mentioned plant.
  • Organic waste occurs in different forms and compositions in municipalities and industry, which can be easily collected separately: organic components from the household waste bin, green waste and other tree waste (branches from horticulture, parks and street plants) - clean wood waste such as B. formwork from construction and pallets from the trade, wood waste from construction demolition contaminated by impregnating agents (e.g. tar oils and formaldehyde) and paints, but also from old track systems, Soils, food residues, food waste and vegetable waste from industrial kitchens, slaughterhouses, dairies, wholesale markets as well as other food manufacturing and processing companies or agriculture, sewage sludge contaminated by tar oils, mineral oil hydrocarbons or other organic substances
  • the biological processes have the advantage that they come very close to the natural decomposition processes and thus cause the slightest changes in the material balance of nature. Lignins and humus substances are preserved.
  • the products of the biological processes can be returned to the food cycle in various forms. Since biological processes have a lower degradation rate than thermal processes, a larger storage or reactor volume is required to implement them. However, the technical effort is generally much lower, which means that the treatment costs are significantly lower than those of thermal processes.
  • Two basic biotechnological operations are used for biological waste recycling, which have their specific effect and their preferred area of application: - Composting
  • Composting is particularly suitable for converting solid organic waste materials into soil improvers containing humus. It can mainly be used to break down structurally rich, difficult-to-decompose materials such as grass, wood or pruning.
  • the rotting process is very slow. If there is insufficient ventilation or too high humidity, the process tips and the desired humus formation does not occur. There is an odor nuisance. For this reason, composting requires considerable mixing or compression energy for ventilation.
  • the self-heating of the compost in the first rotting phase leads to a hygienization of the waste. There is a large, hardly usable amount of waste heat.
  • the aeration of the compost leads to mass losses, which are caused in particular by the evaporation of the water, but also by the conversion of organic matter into C0 2 and water.
  • Composts are used for soil improvement in agriculture, horticulture, for soil remediation, soil recultivation and landfill cover.
  • the anaerobic biogas process (fermentation) is particularly suitable for structurally poor, easily degradable, moist waste. With it, the best possible overall utilization of organic matter is achieved. This is predominantly in methane and only to a lesser extent in Converted carbon dioxide.

  • they cause additional difficulties in the process control: formation of a floating blanket or sediment, hinders complete mixing and homogeneous conditions with regard to temperature and concentrations in the anaerobic reactor. This means that more complex reactor designs, increased energy consumption and increasing operating costs for complex cleaning cycles are necessary.

  • a prerequisite for the functioning of the plant according to the invention and the associated method is that the waste which is easily perishable and almost 100% degradable is used in the biogas plant 1. This results in water containing minerals that contains almost no solids. This fermentation substrate is collected in tank 3.
  • the waste which contains structurally rich and therefore difficult to decompose components, is fed to the composting plants 5 and 6, which are supplied with additional nutrients to accelerate the compost through the drain of the biogas plant from the tank 3.
