The project aims at developing new distributed biorefineries and comprehensive concepts based on slow pyrolysis for SMEs. The research carried out in the project "Hidaspyro" will be continued in the new project. The goal is an optimised slow pyrolysis process for new applications of the products. The objective is to determine the effects of biochar and distillates on growth of plants, soil improvement, carbon sequestration and emissions of cultivation, to define the quality criteria of biochar, to determine the potential of distillates in odour prevention and to assess the environmental impacts of the products. Optimal process parameters to produce distillates and biochar of high quality will be determined by well-controlled laboratory-scale slow pyrolysis testing facility to be constructed. The main feedstock material will be birch wood, but comparisons with other biomass feedstocks will also be carried out. The efficacy tests will show the effect of biochars and distillates on growth of plants, use of water and nutrients, and biological activity of soil. Demonstrations of soil improvement and odour prevention will be done in co-operation with the partner enterprises. The environmental effects of different biochars will be compared by following the changes in the activity of microbes and the composition of nematode community. The amount and quality of distillate and biochar safe to the environment will be defined. All the results will be utilised in the techno-economic assessment of different concepts.
