Citizens and the city collect garden and
park waste
Biomass is turnedinto biochar
through public and private
collaboration
Biomass is turnedinto renewable heat
for the districtheating system
Biochar is usedin soils in
gardens and parks

How to produce and use more biochar?Why not an
add-on technology for
existingburners?
What to do with the heat when there is no need for heat?
Can we achievecarbon credits,
climatecompensation or EU
subsidies for farmers?
From a legal perspective,
what is biochar?
How to classifya biochar
production unit?
How to incorporateexpensive biochar
use on a farm?Closer to an approvalfor biochar in organic
production in EU.
