Waste and recycling company Raumarike Avfallsforedling IKS (RoAF) of Norway, and German equipment supplier Stadler have been recognized by the German-Norwegian Chamber of Commerce with an Innovation Award for the fully automated waste sorting plant they recently installed in Oslo. The two were chosen from a field of 12 entrants.
The sorting system was supplied by Stadler and is operated by RoAF.
According to Stadler, the Oslo plant has a processing capacity of 30 tonnes per hour of municipal solid waste (MSW). The facility, completed in three months, contains 14 near infrared (NIR) sorting units, more than 300 tonnes of steel and 1,300 square metres of walkways, covering six floors and reaching 15 metres in height in some places, the company says.
Due to the plant’s automation the company requires only two operating staff to load the waste and remove the baled materials, Stadler reports. The rest of the operation is monitored and controlled by closed-circuit television.
To ensure the plant maintains its efficiency, it relies on the community to sort all their waste into colour-coded bags. Upon receipt at the plant, the NIR units sort the material according to colour and process accordingly. Food waste is diverted to an anaerobic digester with the resultant gas used to fuel the public transport system.
The judging panel for the awards referred to Stadler’s complicated sorting accomplishment, concern for the environment and consideration for staff members as reasons for receiving the award.
Stadler says the design, manufacture and construction of the plant was carried out on time and on budget. Overseeing the design and commissioning was Ben Eule, Stadler UK’s global technical manager.
Trevor Smart, Stadler’s UK sales manager, singled out Eule’s work for praise. “The whole team in Germany and the U.K. are very proud of this plant and the work Ben has done to ensure its success,” says Smart. “It is groundbreaking from a design point of view and presented many challenges around the full automation of the plant, together with the very tight timeline. Despite these issues, Ben was able to deliver on all levels — we are very lucky to have him based here in the U.K. and have his expertise available to us.”
Eule adds, “I am delighted for RoAF and Stadler that the innovation involved in developing this plant has been recognised. From a personal point of view, it is rewarding to see the facility working well and for our hard work to be acknowledged.”
