Answer 2

Answer:

Biogas is a green energy source in form of electricity and heat for the local grid.

Considerable environmental advantages - less emission of the greenhouse gasses methane, CO2 and nitrous oxide.

Environmentally friendly recirculation of organic waste from industry and households.

Less odour inconveniences when spreading slurry on the fields - fermented slurry smells considerably less than normal slurry and the smell decreases faster.

Plants absorb fermented slurry better, increasing the yield on the fields.

Protection of subsoil water - improved nitrogen exploitation reduces leaching and thereby drinking water contamination.

Reduced costs for artifical fertilizer
