Wood-like bio-mass is normally produced in forestry. Forestry biomass refers among other things to trunk wood, rough wood, bark, remnant forest wood and landscape maintenance material. Although the cultivation of fast-growing trees on arable land for energy production really counts as wood-like biomass, it is assigned to the agricultural biomass. This wood-like biomass is harvested or collected and channeled into suitable utilization routes. High-quality biomass such as rough or trunk wood but also bark are used materially as a rule. Other types of wood-like biomass occur as by-products in material utilization such as sawing by-products, industrial wood waste, old wood and black liquor. These can be used materially in turn as required, for example, for paper production or the manufacture of chipboards, prepared for energetic use and passed on for thermal recycling as a rule.
