 Workshop on:

Greenhouse Gas Aspects of Biomass Cascading -
Reuse, Recycling and Energy Generation

Jointly organised by


Background information

Scope and objectives of the conference

The reduction of greenhouse gas emissions is an urgent international target. The sustainable use of biomass  for wooden products and energy is one important option that might significantly contribute to the reduction  of greenhouse gas emissions by substituting the use of non-renweable materials and fossil energy. Given that the amount of sustainably available biomass is limited, the most efficient use of biomass is an important issue. Biomass offers a wide range of possibilities to reuse, recycle and to generate energy. The main objective to be addressed and discussed in this joint workshop was the optimal combination of the different aspects of carbon sequestration and biomass cascading to contribute to greenhouse gas reduction by substituting conventional materials and fossil energy. It provided a forum for government, policy and academic representatives to exchange  information on current knowledge regarding optimal use of biomass for greenhouse gas mitigation.
