Stadler installs fully automated waste sorting plant in Norway
<![CDATA[
Stadler Group, Colfax, North Carolina, commissioned what the company describes as the world’s first fully automated waste sorting plant in late 2015. Located in Skedsmokorset, Norway, near Oslo, the company says plant features advanced automation.
The plant is operated by waste and recycling specialist Romerike Avfallsforedling (RoAF). The municipal solid waste recycling and anaerobic digestion biogas facility took nearly four years from concept to completion. The sorting system took three months for Stadler to construct.
RoAF is an municipal waste company responsible for 10 Norwegian municipalities. The company serves 190,000 households and handles some 104,000 metric tons of waste annually, 75 percent of which is household waste.
Waste collection in Norway is based upon a three-container system: The first is a specially designated green bag for food waste, plastic and residual waste; the second container is for paper and cardboard; and the third is for glass and metal packaging. There is also a red bin for electronic and hazardous waste.
Stadler says while the plant features well-known technology, it is integrated in a new way. The system includes:
- 16 NIR (optical) sorters;
- two trommels;
- two bag openers;
- two ballistic separators;
- an eddy current separator;
- multiple overhead magnets;
- one vibratory screen;
- a shredder; and
- a windshifter.
“One of the important criteria for the facility, and an indication of where the market is going, is that it could not include any picking lines,” says Mathew Everhart, president of Stadler America. “The elimination of star screens for primary separation has significantly reduced the amount of system downtime, maintenance costs and total operating staff.”
Originally designed to process 30 metric tons per hour (tph) of MSW, the plant was expanded in October 2015 to increase its capacity to 40 tph.
The process for material arriving at the plant is as follows:
- waste reception
- sorting of green bags – Line 1
- main sorting line with separation of paper – Line 2
- polymer-sorting – Line 3
- recovery of metals
- baling and loading
Stadler says one of the major advantages to the plant’s automation is that it requires only two operating staff to load the waste and remove the baled materials – there is no manual sorting. The rest of the operation is monitored and controlled by closed-circuit television.
“We are thrilled to be the only recycling plant systems integrator in the world to have designed, built and commissioned such a plant. It truly helped our customer solve a significant waste management challenge while providing them with a solution for many years to come” says Everhart. “This plant, while in Europe, helps to illustrate what Stadler can bring to operators in North America.”
