Production of verbiogas

verbiogas is produced in an entirely new type of bio-refinery. It is made exclusively from agricultural waste such as distillery slop, a by-product of bioethanol production, and straw. No foodstuffs are used.

The distillery slop is pumped into fermenters with a capacity of 8,000 cubic metres. The straw is mechanically chopped up and also placed in the fermenters. The biomass is left in the fermenters with the addition of bacteria for about 30 days. During fermentation, raw biogas is produced comprising about 60% methane. It also contains carbon dioxide, sulphur and inorganic elements, which are removed in the next steps in first a desulphurization plant and then a CO2 capture plant. The inorganic components are also removed.

verbiogasThe resulting biomethane with a purity of 99% is then fed into the natural gas grid. Ammonium sulphate solution, phosphate and potassium are also produced and can be used as organic fertilizer.

VERBIO received the Biogas Innovation Prize for this technological development from the dena Germany Energy Agency.

VERBIO sells verbiogas at filling stations selling natural gas in Germany, which are largely run by local municipal utilities.
