Waste flows

General information

TNO did a research for Almere on waste streams in the city and volumes. The central question was: which waste fractions have the greatest potential to make a better business case through another (new) circular production process for waste treatment?

Key indicators: What is the fraction of waste? What are the processing of the waste fraction? What materials contains a fraction of waste? Which products and product components contain a fraction of waste? What materials are most valuable? What jobs can be drawn to the region? At what scale should be collected? Who are the customers?
