Overall objective of the project is to build the public understanding about the economical and technical benefits on the use of biomass for energy production, based on studies of biomass availability, technical-economic aspects and environmental protection. In order to achieve the project aims there are defined following tasks: 1. To make the resource assessment analysis on regionally available biomass, determining environmental and technical-economic aspects; 2. To make the assessment of the biomass (forest), use satellite methods; 3. To make the territorial mapping of the regionally available biomass; 4. Prepare detailed regional biomass resource management plan, which includes the evaluation of territories from real biomass qualitative and quantitative coverage as well as technical-economic feasibility of using biomass for specific areas and financial analysis of the implementation of the results (including pilot projects); 5. To make quantitative and qualitative analysis of other regionally available biomass resources types; 6. Make the testing of the regionally available biomass to determine the technical-economic parameters (incl. pilot projects); 7. Prepare the informational base for the local authorities, public, biomass and energy producers about biomass as technically, economically and environmentally friendly energy source (ES) containing the guidelines detailed for the financial-economic calculations and business plan development.

Achievements: The PURE BIOMASS project set out to enhance public understanding with regard to the economic and technical benefits of the use of biomass for energy production, based on studies of biomass availability, the techno-economic aspects and environmental protection. The partners from Latvia and Finland worked jointly to evaluate all available biomass in the project region. They created biomass resource maps by using satellite methods as well as a model of energy supply and demand to understand the fossil fuel replacement costs with biomass. Resource competence tools were created to support the models implementation. Additionally, other regionally available biomass resource types were tested in order to determine their technical-economic parameters. The project promoted biomass as a technically, economically and environmentally friendly energy source, including detailed guidelines for financial/economic calculations.
