This work concentrates on the feedstocks which attract the highest commercial interest.
The feedstocks to be processed are selected based on availability and price. The first feedstock is characterised as white wood or clean wood which does not include bark. The second feedstock is residues: branches and tops of trees from logging operations which are called forestry residues. Forestry residues include bark and significant amounts of extractives.
All feedstocks are subject to mechanical harvesting.
Then, the raw material is transported, in general in a truck-trailer unit, to the pyrolysis production plant. In the fuel supply chain as a whole, transportation of fuel to the conversion plant can be a major cost, typically 30-50 % of the delivered fuel cost.
