Biochar
Stockholm's collected garden waste is turned into biochar which is used as
soil conditioner in plantations and renewable energy. The city becomes
greener while the residents make an important contribution to the
environment and the climate.

About the Biochar Project
Stockholm Biochar Project uses park and garden waste to produce biochar and
renewable energy.

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.
