Примери за biogas

• This paper will focus on grass-clover leys for biogas-based electricity and rapeseed oil as replacement for tractor diesel.

• The enterprise combination for a marginal farmer under low risk levels was crop (0.25 ha), dairy (1 unit), fishery (0.25 ha) and biogas (1 unit).

• The authors recommended that biogas be used for electricity production instead.

• Contrary to the rapeseed oil this energy was not produced nor used on the farm, but farm scale biogas production is a possibility18.

• Each family requires a single biogas plant, but large farmers can accommodate more units.

• Animals also contributed significantly to an improvement in soil fertility through manure and biogas production was able to replace domestic fuel needs.

• Popularization of biogas is slow and caters mainly for heating (cooking, boiling, etc).

• The solid component is used for biogas production.

• The biogas would then have been passed through a specially developed tubular solid oxide fuel cell that generates electricity directly.

• The fertilizing effect of compost and biogas residues from source separated household waste.

• Producing and using biogas for traction would require unrealistically large, high-pressure storage facilities on the farm to meet peak season demand.

• Therefore, only slight variations were expected in the digested slurry and in the two fractions produced by separation immediately after the digested slurry leaves the biogas plant.

• Animal slurry is anaerobically digested in biogas plants with the purpose of producing energy.

• Biogas fermentation residue was the only soil amendment and the crops planted were alternated every year since 2002.

• However, at the highest risk level, the enterprise allocations were crop (0.75 ha), dairy (1 unit), fishery (0.25 ha), mushroom (0.72 units), apiary (2 units) and biogas (1 unit).
