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

Residual waste Optical sorting
Waste collection, sorting and treatment
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 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 !
Oslo’s citizens help make food waste into biogas and fertilizer, and give
plastic packaging new life.
Soon the whole city will
