vedrester

Vedrester is a Nordic term used to describe residual wood materials generated by forestry, logging operations and wood processing. It covers a range of byproducts such as branches and tops, sawmill offcuts, trim and planer shavings, sawdust, chips, bark, and other fragments not incorporated into primary wood products.

Sources and types: Vedrester originate from harvesting activities, lumber mills, carpentry shops, and pulping processes. The composition varies with operation, but common components include bark, small offcuts, and finely divided material such as sawdust. Moisture content and particle size depend on processing method.

Uses and value: Vedrester can be used as a feedstock for energy and materials. In energy applications, it supplies biomass for heat and power and can be processed into pellets or briquettes. It is also used as mulch or soil amendment, animal bedding, and a raw material for composting or fiber products. In some cases, residues are redirected to pulp and paper processes or engineered wood products.

Environmental and handling considerations: Managing vedrester as a resource reduces waste, but storage and processing require attention to moisture, temperature, and pest control. Wood residues can self-heat and pose fire and microbial risks if stored improperly. Regulatory status varies by country; some vedrester streams are treated as renewable energy feedstock, while others fall under waste management rules until valorized.
