Dumping of soil, building rubble, sewage sludge (- 340,000 t)
Recycling, composting of organic waste (+ 72,000 t)
Recycling of glass, paper, packaging and scrap metal (+ 41,700 t)

plus weekly kerbside collections
40,600 tonnes p.a. = 79 kg per inhabitant

14. Result at Kronsberg: Example Soil Management
700,000 m3 excavated soil re-used, making about 100,000 lorry journeys unnecessary and thus saving 1,200 tonnes of CO2 emissions

15. Example: Construction Sites
Waste sorting on site
Recycling of waste from demolition and modernisation projects
