‘‘ Creating GreenBusiness together
94 % of all household waste is eitherenergy 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

Challenges
• Communication: Meeting targets require citizens engagement – communications is key
• Technology: Industrial focus essential for the success
• Energy: Global trade in waste
www.oreec.no
‘‘ Creating GreenBusiness together
• 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
