In New Zealand biomass is derived from three sustainable sources: Municipal waste, agricultural and food processing residues, and plantation forestry.
Using the organic waste or residues from communities and manufacturing is a key objective of sustainable living. It also makes sound sense and can lead to economic benefits of new products and employment. We are good at producing waste and we do it 365/24 so it is a no brainer that we should look at the value that we can extract from it. Energy and the co-products of energy is one of those products.
Biogas technologies can be used to reduce animal effluent run-off to waterways and agricultural residues can be used to improve operating performance of anaerobic digestor equipment.
Because bioenergy is sourced from combustion of plants who absorb CO2 to grow bioenergy is considered to be near carbon neutral. It is not 100% carbon neutral as some CO2 is produced from equipment recovering the biomass, processing it into fuel and transporting it to a customer.
