Biochar is a fantastic soil conditioner that retains water, air and nutrients in the soil. Once in the soil biochar is a carbon sink that contributes to a greener city and that decreases the levels of carbon dioxide in the atmosphere for hundreds to thousands of years.
The energy becomes heat for the city's district heating network within Open District Heating TM – a project to recycle excess heat in Stockholm city.
Stockholm Biochar Project's goal is to produce heat for 400 apartments and to create a carbon sink corresponding to the yearly carbon dioxide emissions from 3500 clean cars. This way we are doing a small – but important – action to save the world.
