Oslo Integrated Waste Management System P책l Mikkelsen Director, Waste-to-Energy-Agency City of Oslo
City Climate Leadership Awards Conference, September 5 th 2013
Oslo - The Winter Capital goes Green
City profile
Population 613 000 The capital region 1.14 mill Population growth 2%
Policy development Urban Ecology Programme Environment and Climate Action Plan Cycle based integrated Waste Management Strategy Main principle: Waste Management Hierarchy
Waste reduction
Reuse
Material recycling Energy recovery Land fill
Actions: Efficient sorting and re-use of domestic waste for all the inhabitants from June 2012 94 % of all household waste is either energy recovered or material recycled 90 % of all inhabitants live within 300 m from a waste return station
340 000 homes >
optical sorting
Household waste: • Organic waste -> biogas and fertilizer • Plastic waste -> new products • Waste (RDF) -> district heating and electricity

Optical sorting plant (Optibag) World’s biggest, the only one with mechanical pre-sorting Line A and B; Haraldrud - 100 000 t/y (1. oct 09) Line C; Klemetsrud - 50 000 t/y (april 2012) Sorted food waste; 11 161 t, plastic waste; 3263 t (2012)
Biological treatment • • • • •
Food waste from households in Oslo Organic waste from the market Biogas plant capacity: 50 000 t/y Biogas for 135 buses/lorries Bio fertilizer for 100 farms
Plastic is recycled • Every citizen in Oslo produce 25 kg plastic waste each year • One kilo recycled plastic saves two kilos oil • Recycling in Germany
Energy from Waste (RDF) DISTRICT HEATING 840 GWh; provides heat for 84 000 households
ELECTRICITY 100 - 160 GWh el. for schools in Oslo TOTAL CAPACITY 410 000 t/year (100 000 t/year RDF import)
Challenges Communication: Meeting targets require citizens engagement – communications is key Technology : Industrial focus essential for the success Energy: Global trade in waste
Outcomes Running buses on biogas provides cleaner air and less noise in the city Recycling Oslo’s food waste reduces our emissions by 10,000 tons of CO2 per year
Oslo’s citizens help make food waste into biogas and fertilizer, and give plastic packaging new life.
Recycling 1 kg of plastic replaces product from 2 kg fossil oil District heating and electricity produced from waste replaces 1TWh of fossil fuel 3 – 5 years to see the final outcomes, Communication is essential !
Soon the whole city will
