Usage of vegetative
cultures for biogas production became a new direction in European
agriculture. More and more cultivation areas are used for energy crops
that are suitable for biogas production. If company doesn’t have
any waste products but has lands and energy demand it can use renewable
energy sources.
Fertilizer expenses
are very low due to usage of high quality fertilizer produced by biogas
plant.

The biomass feeding into the reactor is batched, which preserves
sensitive methane bacteria from any harm. That gives process stability
and biogas production with high methane content. For biomass mixing
hydraulic mixing system is used. Produced biogas collected to outer
gasholders.

Peculiarities
From gas yield point of view
plants can give one of the highest biogas yield. Almost any green or
ensilaged plant is suitable for biogas production. From the economic
feasibility point of view the following plants are most applicable for
biogas production: corn silage of milky and waxy ripeness, Sudan grass,
poic silage, mixture of clover with other grasses, grains silage, sugar
and fodder beet with tops, potato, grains.
Hydraulic
mixing system
Today corn silage is most
effective raw material for biogas production. This plant gives good
crop yield from hectare as well as biogas yield from 1 ton of raw
material. Corn silage production costs are not very high and farming
machines for its cultivation available almost at any farm.
Energy crop rotations are practiced in Europe, it means that one energy
crop replaced by another enabling get green biomass twice a year,
suppress weeds growth and save costs. Two cultures can be grown
simultaneously, for example corn and sunflower or corn and millet
grass. That method increases nutrients content and stabilizes crop
yield during dry seasons.

Peculiarities
Due to high dry matter
contend bioreactor feeding unit is not equipped with pumps. Screw
charger are used for this material the transported to the screw charger
by tractor and fed into bioreactor by portions. For maximum biogas
yield fermentation takes place in two bioreactors. The second one is
called after-fermentation reactor and is also equipped with heating
system, control gauges, gasholder with inflatable dome. Usage of energy
crops gives high biogas yield that can be used for electricity and heat
production in co-generation unit. As an option the gas can be treated
up to biomethane and used as a vehicle fuel.
