The findings follow the City of Oslo’s decision in 2012 to make source sorting of food waste mandatory and work towards achieving 50 per cent food waste recycling by 2018.
The increase from 43.9 per cent in 2016 also points towards continued growth and provides hope that Oslo can meet its target before the end of 2018
The Municipality of Oslo claims that much of its success is attributable to its citizens’ efforts to source sort their household waste and Envac’s Optibag system, which is part of the city’s waste collection strategy. The system enables waste deposited in colour-coded bags to be automatically sorted at the end point using sophisticated optical sorting technology.
The report also highlights how food waste recycling, which is carried out in green coloured bags, has increased from 33.3 per cent in 2012 when the City of Oslo’s first of two Envac Optibag sorting systems now in place became operational.
Nils Finn Lumholdt, Production Director, Material recovery, at the Waste-To-Energy Agency, who is responsible for the sorting plants, comments: “This is a huge achievement not only for Oslo, but for Norway, too. We knew that achieving 50 per cent would be a challenge, however the Optibag technology has delivered pinpoint accuracy and enabled us to send food waste to be used in biogas and bio fertilizer production, and plastics to be used as part of a successful plastics recycling programme. We’re delighted with the results and extremely very pleased to have found a partner in Envac Optibag.”
The study also reveals how Envac’s Optibag system has helped the City of Oslo boost its plastic packaging, collected using blue coloured bags, to 29.7 per cent – up from 20.2 per cent in 2012.
Joakim Karlsson, Chief Executive at Envac AB, adds: “Envac Optibag is now leading the way when it comes to developing sustainable waste collection solutions that can significantly improve municipalities’ efficiency ratings and environmental credentials. The City of Oslo has demonstrated what can be achieved when combining aspirational targets with cutting edge waste collection technology and I am proud that we have played a part in its much-deserved success.”
