  • Waste wood which is classified into different waste classes, is usually collected centrally, but in particular pre-sorted by non-professionals.

In a large number of countries with a recycling structure that has not yet developed, such pre-sorting does not even take place. As a rule, impregnated or tarred wood is disposed of directly and all other wood (solid wood mixed with wood-based materials) is sent for recycling in containers.
  • the collected and non-uniform starting material is subjected to an initial crushing, as is usual in recycling. Foreign matter is then removed from the shredded starting material until reusable waste wood can be recycled with the highest possible degree of purity.

  • the waste wood should be sorted into solid wood and artificial wood after an initial cleaning of foreign matter (metals, non-metals, plastics).
  • the separated solid wood provided it is in chip size, can be used in the production of high-quality panels due to its properties being the same as wood chips from fresh wood. It should be noted that the proportions are variable. Buffer options should be provided so that the ratios between solid wood (from recycling), wood materials (from recycling) and fresh wood remain approximately the same for the production of a batch of material boards in order to avoid quality differences in a batch.
