  1. Cycle-Based Waste Management in Oslo

  2. A complete solution for a cycle based waste management system in Oslo

  3. Waste-to-Energy Agency (EGE) • Agency in the City of Oslo, organized under Department of Environmental Affairs and Transport. • Waste-to-Energy plants located at Haraldrud and Klemetsrud. • EGE recovers 250 000 tons of waste yearly, thereby 130 000 tons of Oslo’s household waste. • Destruction of infectious waste from hospitals, and fractions that demand special treatment. • The energy from our plants is utilised in the district heating net in Oslo and as electric power in the electricity grid. • Producing energy from waste is a socio-economic and environmental favourable way to treat waste that cannot otherwise be recovered.

  4. Political objectives in Oslo • 50 % reduction in emissions of greenhouse gases by 2030. • Plan for residual waste treatment - 2006 – 2009: • 50 % recovery of materials in by 2014. • Source sorting of food waste and plastic packaging by the end of 2011. • Increased use of renewable energy: • Basis for increased use of district heating, 1 - 2 TWh. • Change from fossil fuels to renewable fuels for the district heating system.

  5. Scope of development ”EGE 2010” • Optical sorting plant for food waste and plastic packaging • Biogas factory producing biogas (fuel) and biofertilizer from food waste • A new waste incinerator line

  6. Plan for EGE 2010 Phase Start End Pre-studies 01.09.06 31.03.07Specifications and Contract signing 01.04.07 30.06.08Planning and Building 01.07.08 30.09.10Take over 01.10.10 31.12.10

  7. Source sorting in coloured plastic bags – optical sorting Receipt pocket/transporters Optical sensors

  8. From food waste to biogas and biofertilizer Biogas factory

  9. Biogas factory

  10. Food waste + sewage = biogas

  11. Biogas production – key figures

  12. Waste incineration today: • Key figures for incinerator and boiler: • Capacity: 20 t/h – 160.000 tons/year – 2 waste incinerators (80.000 tons each) • Thermal power: 49 MW • Electric power: 10 MW • Energy delivered (GWh): 2007 • District heating 285 • Electric energy 75 • Total 360 • Produced steam – approx. 370 °C/40 bar • Electric gas motor: 12 GWh

  13. The new waste incinerator • Key figures for waste incinerator and boiler: • Capacity: 20 t/h - 160.000 tons/year • Power: 49 MWt 10MWel • Energy delivered (GWh): 2007 2011 • District heating 285 573 • Electric Energy 75 140 • Total 360 713 • Produced steam – approx. 400 °C/40 bar • Best available technology (BAT)
