Forestry resources for biofuel production
Two main types of forestry resources are used for demonstrations of second generation biofuel production:
a) Residues from harvest operations that are left in the forest after stem wood removal, such as branches, foliage, roots, etc.
b) Complementary fellings which describe the difference between the maximum sustainable harvest level and the actual harvest needed to satisfy round wood demand.
Forest residues can be converted to BioSNG, biocrude or BtL through various thermochemical pathways. The world's first BioDME plant was recently initiated in Sweden, using black liquor from forest residues via gasification.
EuWood - Real Potential for Changes in Growth and Use of EU Forests is looking at biomass demand, supply, potential and constraints and review of policies. For further information, you may download all presentations (8Mb Zip file) from the EUWood Stakeholders meeting on 4 2010 June.
Futureforest project is a partnership of regions sharing ideas on how the forests of Europe could adapt to climate change using innovative natural solutions, contribute towards carbon sequestration and reduce risks caused by climate change such as flooding, drought, fire and soil erosion.
In Austria, M-Real Hallein AG is developing a concept to produce bioethanol from wood sugars derived from sulfite spent liquor (SSL), a by-product of paper and pulp production.
