In the organic waste refinery "BW2Pro“, one ton of biowaste is to be processed daily into high-quality products and raw materials.
By means of high pressure and high temperatures, the biowaste is split and separated into a fibrous solid fraction and a liquid fraction. Almost all parts of the biowaste are further processed or used.
Medium fibers are pressed into products such as flower pots. Short fibers serve as a carbon source for the production of cellulase, which is contained in many detergents, for example.
The liquid fraction is fermented to produce biogas, and its digestate is used as fertilizer. Part of the liquid fraction is used to produce biodegradable bioplastics.
The BW2Pro project will be integrated on an already existing biogas plant of the Waste Management Rems-Murr. Waste Management Rems-Murr was involved in the planning of the project consortium at an early stage. Associations also support the project locally.
The project shows how biowaste can be recycled in municipal biogas plants. Here, the modular structure of the project is of great importance, as individual modules could be integrated on existing plants and thus the existing technology can be supplemented.
