The objective is the process development for the manufacturing of a solid, storable and emission-free biological product from unused organic waste and residual material fractions of the food processing industry with soil improving properties that may be modified. The Nutricoal product is based on biochar, which is obtained by pyrolysis from organic waste from the meat-processing industry and of which the industry has difficulties in disposing so far. Depending on the desired product properties, specific functional chemical groups are generated on the coal surface by special activation measures.
To charge the coal with nutrients, anaerobically processed slaughter waste, i.e. fermentation residue, is concentrated using an innovative low-temperature process (membrane distillation) and used as a nutrient supplier. In addition to the concentrate, pure water is obtained, which can be used as process water. The membrane distillation process is being developed by AEE INTEC as a part of the project.
In the project, the entire process chain will be tested at individual pilot plants operated by the project partners, the results will be evaluated in the laboratory and used as a basis for simulations. At the end of the project, the product quality and the energy efficiency of the process should be assessed and the dimensions of a possible pilot plant should be determined.
