From the international enzyme specialist
More control, more power
DSM has developed enzymes specifically to improve the output of biogas plants. We build on our 100+ years of experience in the development, manufacturing and application of enzymes to best serve the biogas industry.
We have developed biogas enzymes for fiber rich substrates (such as maize, grass and manure), for cereal-based substrates (rye, triticale, wheat, barley) and we can provide case specific solutions for your needs.
Our products come in concentrated, liquid form, which makes them easy and safe to use.
Our products
MethaPlus®
Application: fiber-rich substrates
Examples: maize, gras, manure
MethaPlus® enhances biological activity in the digester, which increases the production of biomethane.
Continued use in biogas plants since introduction in 2005 makes MethaPlus® the best tested enzyme product in the market.
Benefits of MethaPlus®
- Increases conversion
- Reduces viscosity
- Dissolves floating layers
Axiase™
Application: cereal-based substrates
Examples: rye, triticale, wheat, barley
Axiase™ contains several enzymes that address the mucilaginous (‘slime forming’) properties of these substrates. These break down long-chain molecules (not soluble in water) into shorter, water-soluble molecules, therewith avoiding viscosity issues.
Benefits of Axiase™
- Enables use of (more) cereal-based substrates
- Avoids and dissolves floating layers
- Better flowability, for lower energy use and less wear
Case specific solutions
Application: Enzyme solutions specific to your substrate.
Examples: straw, sugar beet pulp, sewage sludge.
To address specific biochemical characteristics of these substrates that bring operational challenges.
Benefits of our case specific enzyme solutions:
- Enables (increased) use of complex feedstocks
- Can be used at low cost and without investing in equipment
Support in optimizing your plant
Working with DSM and our distributors means benefiting from a wealth of expertise in fermentation. Step-by-step we will support you in optimizing your biogas plant:
- Recording of relevant parameters
- Assessment of performance (substrate consumption, gas yield, process stability)
- Determination of improvement potential
- Recommendations regarding the use MethaPlus®, AxiaseTM or other enzymes
- Advice on additional measures for plant optimization
- Continued technical support, for example with substrate changes
How do enzymes work?
In each anaerobic digester, enzymes exist naturally. They play a crucial role in the digester’s biology: they release sugars from the substrate, which microorganisms require as energy source when converting the substrate into biomethane. However, the amount of enzymes that is ‘naturally’ present in the digester is insufficient to provide enough sugars to the microorganisms. This limits the conversion of substrate to gas.
DSM enzymes break down the long-chain sugars (polysaccharides) contained in plant fibres. This results in more biological activity in the digester. Enzymes also break down other complex molecules, so that these can be converted into methane and viscosity issues, such as floating layers, are avoided.
