Motivation
- Strong growth of biogas plants
- Efficient pre-treatment and digestion of biomass, sewage sludge or animal by-products
- Enables higher grades of anaerobic degradation
- Production of storable energy with pyrolysis
- Extended added value (pyrolysis-oil, -gas and biochar)
- Increase of efficiency and decline costs of biogas plants
Conclusion and Outlook Summary
- Efficient pre-treatment and digestion of biomass is necessary
- Appropriate disintegration processes (like TPH) may be one option, since they allow a better bioavailability and homogenization of the input
- Biogenic residues must not be grown, fertilized and harvested – they incurred regularly and should already be reasonable recycled
- Energy supply based on biogenic residues which are not yet useable represent an advantageous option for efficient biomass use
- Intermediate pyrolysis – improving profitability and efficiency of biogas plants
