A renewable energy technology that generates heat and electricity from waste
Anaerobic digestors follow the same principles as landfill gas capture systems, capturing the methane released by decomposing organic waste such as food or slurry and then burning it to create heat and electricity. The resulting residue can also then be used as a fertiliser.
The technology is becoming increasingly popular across the agricultural sector and advocates claim that it is more cost effective than many alternative renewable energy systems.
