As part of our portfolio, we supply enzymes to biogas producers. We import these enzymes into Europe from China. Enzymes are proteins that act as biological catalysts (biocatalysts). Catalysts accelerate chemical reactions. The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products. Almost all metabolic processes in the cell need enzyme catalysis in order to occur at rates fast enough to sustain life. Metabolic pathways depend upon enzymes to catalyze individual steps. Enzymes are known to catalyse more than 5,000 biochemical reaction types.
Our Cellulase enzyme supports the bacteria that convert cellulose found in for example fibers of straw, maize silage, etc. The Pectinase enzyme helps to convert pectin, found in for example rye.
Our customers use our enzymes to improve the gas production of their digester. With the enzyme, the reaction speed of conversion of the raw material, for example maize silage, is increased and the digestate contains less undigested material. More gas is being produced from the same amount of raw material. Or the digester already takes out all the gas from the raw material, but with help from the enzyme, more raw material can be added and still convert all the raw material to gas with a shorter retention time. In other words, a digester can digest more raw material than without the enzyme.
Even a short-term use of enzyme can reduce an unwanted floating layer of straw that originates from manure from barns or that is being used as a raw material.
