The group of biogenic residues and waste materials consists of a large number of individual biomasses which can be divided into five groups according to their origin (see table below).
Table: Aggregation stages of biogenic residues and waste materials with examplatory individual biomasses. Source: Brosowski et al. 2019
|Aggregation level||Single biomass (examples)|
|forestry by-products||logging residues (coniferous, deciduos), bark, by products of wood processing industries and wood shavings, black liquor, waste wood|
|agricultural by-products||cereal straw, cattle slurry, cattle liquid manure, beet leaves, rapeseed straw|
|municipal waste||bio waste from private households, green waste, kitchen and canteen wastes, sewage sludge from public wastewater treatment plants|
|industrial waste||residues from milk processing, vegetable processing, biodiesel production|
|residues from other areas||wooden materials from landscape management, stalks from roadside greenery, woody biomass|
|from roadside greenery, railway lineside stalks, railway lineside wood|
Currently, about 65-85 % of the technically usable biogenic residues and wastes in Germany are used for material (e.g. as animal feed or litter) or energetic purposes (Brosowski et al. 2019).
What could be the 5 most important biogenic residues and wastes in Germany (measured by the amount available)? The scientific paper by Brosowski et al. 2019 could help you to answer this question.
