A significant portion of resources is lost when passing through the urban biosphere. The implemented NBS for mitigation or treatment purposes shall become sources for a variety of resources to be harvested, used, reused and recycled. Therefore, possible sources and implementation strategies within the urban biosphere shall be investigated.
Identify, appraise and assess the available resources in the urban context, like waste- or runoff water, liquid and solid waste streams, materials from the other WGs, urban pollutants, etc. Combine innovative NBS applications like regenerative biological systems, phytomining or biomining, biofiltering, etc. The outcome will be the creation of new areas for urban farming, waste treatment, runoff treatment and so on.
