TECHNOLOGY
Biogas Plants produce biogas and bio-fertilizer from biological wastes of agricultural and food industries by means of oxygen-free fermentation (anaerobic digestion). Biogas plants – are the most active system of biological recycling. This system performs utilization, recycling and has the shortest payback period.
The following raw materials can be used for biogas production: cattle manure, pig manure, chicken dung, slaughterhouse waste (blood, fat, entrails, and rumen content), plants waste, silage, rotten grain, waste water, fats, bio-waste, food industry waste, malt remnants, marc, distillery slop, bio-ethanol plant slop, brewer’s grain (crushed malt remnants after filtration), sugar beet and fruit pulp, sugar beet tops, technical glycerin (after biodisel production), fibre and other starch and treacle production, milk whey, flotation sludge, dewatered flotation sludge from municipal waste water treatment plants, algae. Most of the raw materials can be mixed with each other.
Synonyms for biogas are such words as sewage gas, marsh gas, methane. The process known as decomposition or anoxic fermentation and follows food chain involves different microorganisms metabolizing carbon from organic matter in oxygen-free environment (anaerobically). In the process of fermentation, biological waste produces biogas. This gas can be used as natural gas for technological purposes, heating or electricity production. It can be stored, pumped, used as vehicle fuel or sold. In order to produce electricity no additional treatment of biogas is required.
A significant by-product of biogas plants is the production of high quality bio-fertilizer. Bio-fertilizer is a commodity. The quality of bio-fertilizer is higher than mineral fertilizers and the net cost almost equals to “0”. As a commodity it can be sold to anyone.
