The sponge city concept<\/h2>\n\n\n\n

The Stockholm method with biochar<\/strong> contributes to the sponge city of the future and improves climate adaptation measures in cities, e.g. for green roofs and facade greening. In addition, biochar boosts urban tree health and improves soil quality.<\/p>\n\n\n\n

Root spaces are expanded with skeleton soil (coarse gravel, 100-150 mm grain size) under paved surfaces or connected to natural root spaces.<\/p>\n\n\n\n

The fine substrate of quartz sand, biochar and compost remains permanently permeable to air and water<\/strong>. Inlet shafts channel rainwater and support gas exchange. Additional root space can be used as a trench.<\/p>\n\n\n\n
