Topic

The innovation of the project includes the combination and further development of digestion processes for the pretreatment of lignocellulosecontaining substrates. For the pretreatment, the
substrates are disintegrated mechanically and then chemically and enzymatically treated. 
Through the investigation of different residual materials a concept is developed, that enables the use of these residual materials in a biogas plant. It is taken into account that, depending on the
composition and origin of these residues, different substrate-specific process combinations may be suitable.

Aims

The projects aims for an concept for lignocellulosic residues that can be transfered into practice and complies with ecological and economic conditions. By developing a substrate-specific
pretreatment concept mechanical degradation, enzymatic treatment as well as basic digestion is taken into consideration. Thus previously unused residual material potentials for biogas production should be developed.

Measures

1. Development of the digestion strategy on a laboratory scale
2. Testing on a semi-technical scale
3. Carrying out practical tests

FH Münster

• pre-treatment of the residual materials
• batch-tests and continuous test to determine the biogas potential and thus the various substrate approaches.
• optimization as well as a selection of the applied digestion strategys for the implementation on a practical scale based on the first results

AGRAVIS Raiffeisen AG

• procurement of residual materials in the project
• preparation of the economic considerations as well as ecological evaluations based on the test results of the investigation of the biogas potential of different substrate digestions
