Biomass

Revision as of 11:35, 18 November 2019 by MCWaste (talk | contribs) (Edited reference)

Biomass is material, other than fossil fuel or peat, which is derived directly or indirectly from plant matter, animal matter, fungi, algae or bacteria (and includes any such material contained in Waste which is termed biogenic material). The proportion of Biomass in Waste Derived Fuel is the basis for the Renewable Qualifying Multiplier [1].

The proportion of a waste feedstock that originates from biogenic material can be used to classify waste into difference classes as shown in the table below[2].

Classification Property Unit Class 1 Class 2 Class 3 Class 4 Class 5
Biomass Content (as received) wt/wt% (mean) >=90 >=80 >=60 >=50 <50
