Liquid additive METHAPRACT series

Product overview

MethaPract is an enzyme formulation tailored for biogas plants with a substrate focus on energy crops. The formulations act in the liquid phase and on solid substrate components to increase degradability and improve fermenter handling.

Key enzymatic effects

• Breaks down plant cell wall structures (notably cellulose) to make energy‑rich substrate components more available to fermenter bacteria.
• Degrades water‑binding hemicelluloses, reducing fermenter viscosity and smoothing surface structures to improve stirring efficiency.
• Helps prevent stratification by reducing floating and sinking layers, supporting stable plant operation.
• Overall effect: increases biogas yield (reported up to approx. 8%).

Available formulations

• MethaPract CS — general formulation for renewable raw materials.
• MethaPract CG — enzyme profile customized for grass and whole crop silage (GPS).
• MethaPract CS Bio — CS formulation in certified organic quality.
• MethaPract CG Bio — CG profile adapted to substrate diversity in organic farming.
