The Klemetsrud Plant is now in the last phase of a national program to put in place a full CCS value chain in Norway. A 6-month pilot has showed that it is working! It will be decided by 2019 if the Klemetsrud Plant is granted the necessary funds by the State to complete the project. If so, the City of Oslo will have a waste management system that cuts GHG-emissions four times.
CCS from non-recyclable waste
Oslo is already considered a global front runner with its circular based waste management system. The core of the system is an extensive system of source separation where high-tech machinery and the inhabitants work together to recycle as much waste as possible. All that is recycled becomes raw material in the production of new products such as new plastic products, bio methane, bio fertilizer, heat and electrical power, which is then transferred back to the city.
Non-recyclable waste and waste that is not properly recycled is energy recovered at the Klemetsrud Plant. The Klemetsrud plant is one of Eastern Norway’s largest land-based industrial companies, and a major point source for CO2 emissions, with annual emissions exceeding 300,000 tons of biogenic and fossil CO2. CCS of these emissions will help cut 12 percent of Oslo’s fossil CO2 emissions.
In reality the climate benefits are far greater than the official statistics shows. Approx. 60 percent of the captured CO2 has its origin from biological sources making CCS from waste incineration “carbon negative”. When CO2 is drawn from the air and deposited, this reduces the emission to less than neutral, going from plus to minus in the emission calculation.
CCS + source separation cuts emissions four times
Introducing CCS to Oslo’s circular system of waste management helps cut CO2 emissions four times:
- waste diverted from landfills prevents methane emissions,
- sorted waste saves CO2 by replacing fossil raw material,
- non-recyclable waste displaces fossil CO2 in district heating and electricity production
- CCS from incineration of non-recyclable waste removes both bio- and fossil CO2 from the carbon cycle.
Global transfer value
Waste is major global challenge with several billion tons of waste generated every year. In the EU 30 percent of all household waste ends up in a landfill. The proposed Circular Economy Package from the European Commission aims to turn waste into resources and thus reducing environmental degradation, reducing CO2 emissions and creating new green jobs. With the introduction of a landfill ban, 65 percent of the waste will be recycled by 2030. The 35 percent non-recyclables will be incinerated and energy recovered like at the Klemetsrud plant.
