Residual material conversion

Generate energy from manure, straw and feed residues – ecologically, economically and with an eye to the future! Converting your biogas plant to agricultural residues offers numerous advantages and ensures that your plant complies with legal requirements and operates economically.

Ecological advantages: Using sustainable resources 

• No competition with food: By using manure, straw or feed residues as substrates, you are relying on biomass that does not compete with food production.
• Alternative to maize: Manure and other residues are a sensible and sustainable alternative to maize – an advantage, especially in view of the statutory maize cap of 30 per cent that will apply from 2026.
• Closing the nutrient cycle: The fermentation residues produced during biogas production can be reused as high-quality fertiliser in agriculture. This conserves resources and strengthens the ecological cycle. 

Economic advantages: Cost-effective and subsidised

• Benefit from the GHG quota: Operators of biogas plants that use residual materials such as manure, slurry, waste or residual materials can benefit from the greenhouse gas reduction quota (GHG quota) for the promotion of renewable energy sources.
• Cheaper raw materials: Compared to maize, residual materials such as manure are significantly cheaper, which means you can reduce your operating costs.

Solid substrates that are difficult to ferment place new demands on feeding technology and fermentation processes. With our comprehensive consulting and support services, we accompany you from the planning stage through technical implementation to regular maintenance of your plant.
