Purpose and goal
Rest till Bäst drives the development towards a climate-smart, sustainable and circular society by developing solutions to minimize the environmental and climate impact from society´s organic residual products at the same time as the useful product biochar is created and carbon storage takes place. The goal is to develop commercial solutions that create negative carbon dioxide emissions and to develop methods to utilize and treat society´s organic waste and develop the use of biochar. A biochar with low levels of pollutants used as soil improvement and cultivation substrates.
Expected results and effects
The use of biochar helps to reduce the amount of carbon dioxide in the atmosphere. It also helps to improve the growth conditions in the city and on agricultural land, as well as reduce the amount of environmental toxins. The short-term project goal is to show that it is commercially possible to convert several different types of organic waste into biochar, including phosphorus-rich sewage sludge. Other goals are to increase the use of biochar through a better match between the properties of biochar and the area of use and to add capital to the biochar system through trade in the carbon sink.
Planned approach and implementation
The third step of the project is both theoretical and practical and is carried out by a broad constellation of actors. It is about further developing how biochar can be produced from various organic waste, including park waste, sewage sludge and algae. Biochar is then used both as a soil improver and to purify stormwater. A method for removing cadmium will be scaled up. In addition, organizational and business effects as well as societal effects will be mapped and described.
