Waste wood is a versatile raw material that is worldwide used thermally, and for the production of material. It is waste and biomass at the same time.
Some waste products are recyclable and find their use in industrial wood processing. The rest are converted into electricity and heat via biomass power plants and thus form a pillar in the energy transition as renewable energies. The requirement for high-quality recycling is qualified preparation of the material.
Waste wood is already materially processed wood that has come to the end of its useful life. After its utilisation, depending on its classification (A1– A4), it can be recycled both materially, e.g. for chipboard, and thermally for the production of electricity and heat.
Green waste is the term used to describe freshly cut, slightly woody or non-woody plant residues, which are often produced as waste in gardening and landscaping as well as in forestry. Through its processing, it can make a significant contribution to renewable energy supply.
Cut down and delimbed trees are also called trunk wood or rootstocks. The solid material needs to be roughly broken up first to ensure that it can then be shredded. The inexpensive fuel is mainly used for thermal recycling.
Due to their cultivation method, tomato plants are laced with additional plastic mesh which is intended as a climbing aid and are unsuitable for composting after harvesting. The only solution is effective volume reduction to obtain an end product for thermal recycling.
