Regional charcoal production: From Stuttgart green waste, for Stuttgart trees

Stuttgart, Germany (2022)

Scale: Beyond City Level

We have been producing regional vegetable carbon from Stuttgart's green waste since the beginning of 2023. By producing the plant carbon, we not only create a large CO2 sink, we also ensure that Stuttgart's urban trees are more resilient to heat events.

Challenge / Goal

With the goal of climate neutrality in 2035, we want to make a supporting contribution, a C sink from and for Stuttgart.

Solution

Vegetable charcoal is not a new invention - but in addition to its real C-sink potential, vegetable charcoal offers many more advantages. For example, the charcoal's sponge effect ensures that it can absorb up to five times its own weight in water. The city of Stockholm already took advantage of this a few years ago and plants every city tree on plant charcoal. SCS GmbH produces plant charcoal from Stuttgart's green waste and offers the resulting plant charcoal as a ready-made substrate for use under city trees. We are convinced of this circular economy: regional green waste, processed into plant charcoal in Stuttgart, reapplied in the Stuttgart metropolitan region.
