Important results from the project
In the Rest till Bäst (residues to best use) project, we develop solutions for managing society´s organic residual products so that the environmental impact is minimized at the same time as a useful product, biochar, is created. By using pyrolysis technology, the nutrient phosphorus remains, but environmentally hazardous substances (such as cadmium) are removed. The water and nutrient holding ability of biochar means that it acts as a soil improver, which can be used in both urban and agrarian environments. Biochar is also very stable in the soil and therefore constitutes a carbon sink.
Expected long term effects
In the Rest till Bäst project, we have shown that all the residual products we have used as raw materials became stable biochar that acts as a carbon sink. We have also shown that biochar can be produced in such a way that the amount of environmentally harmful substances in the resulting biochar is lower than in the materials it is produced from. In addition, we have used biochar in urban green areas to strengthen the plants so that they are healthier and grow better. The result is a better climate, a better environment and greener cities.
Approach and implementation
In the project Rest till Bäst, 15 partners within the entire value chain for biochar have collaborated to jointly improve knowledge about the production and use of biochar. The properties of biochar have been investigated, the carbon sink has been quantified, cultivation effects have been measured, new products and a Swedish certification for biochar have been developed. The accumulated knowledge is presented on the website, www.biokol.org, in a biochar manual for users and in the project´s final report.
