Solum A/S To Open Denmark’s First Autonomous Robot Sorting Plant

Solum A/S to open Denmark’s first autonomous robot sorting plant for C&D and C&I waste with ZenRobotics’ technology

The fully autonomous robotic sorting station opened by Danish environmental services pioneer Solum A/S will sort up to 25,000 tons of mixed waste per year, including combustible waste, bulky waste, metal, wood and plastic. AI-powered robots replace manual processes and operate independently around the clock. The robot sorting plant raises the recycling percentage and the quality of the waste at Solum A/S, improving recycling efficiency, work safety and the circular economy.

Danish environmental services company Solum A/S will open one of Scandinavia’s most modern and advanced sorting plants based on AI and robotic technologies by ZenRobotics. The new plant, designed around ZenRobotics’ technology and distributed by ReTec Miljø, is expected to be operational in the summer of 2022. The new, fully autonomous robotic sorting station will sort up to 25,000 tons of mixed waste per year. Intelligent robots will sort materials such as combustible waste, bulky waste, metal, wood and plastic received from municipalities, industry and businesses.

Robots improve recycling efficiency and reduce risks

The automated robots are powered by advanced AI and sensor technologies which make it possible to continuously fine-tune the fractions and separate different types of waste, thus improving recycling possibilities and the circular economy. Solum’s new robot waste sorting plant consists of multiple robot arms that lift objects up to 30kg and together handle up to 4,000 picks per hour even 24/7. By comparison, a human can handle approximately 700 picks per hour and cannot work 24 hours a day without breaks. The sorting plant eliminates occupational health risks associated with manual sorting, increases the degree of purity by up to 98%, and reduces the associated costs.

The fully autonomous sorting system runs 24/7

Solum’s new facility is a fully autonomous standalone robotic sorting station that is independent from other operations and replaces manual processes in waste sorting. Before robots come into play, the material first goes through a simple screening step where fines and foils are sorted out. The material is then loaded into a feeding bunker where the material flows evenly and autonomously to the robots through a loader. The AI-powered sorting robots work independently and empty the feeding bunker during the day and again during the night when employees on the site go home. In the morning, the employees arrive and fill the feeding bunker, and the process starts all over again.

In Solum, circular business models and sustainability are part of our DNA. For a long time, we have been focused on how we can use new technology to give better solutions for our customers. ZenRobotics’ robot waste sorting station can raise the recycling percentage and the quality of the waste that we handle. The new plant will also create greater flexibility in waste sorting and a greater degree of documentation for waste management

Morten Strandlod, Commercial Director at Solum

We are thrilled to partner with Solum A/S and ReTec to bring the first AI-powered robot sorting plant for C&D and C&I waste to Denmark, placing more robots on the world map. The fully independent and automated waste sorting plant creates a safer and more efficient recycling environment, lowering operating costs and recovering more valuable, high-quality fractions. Modern waste sorting infrastructure is essential to transition to a circular economy and meet the increasing demand for high quality recycled materials. Frontrunning operators like Solum are leading the way.

Jarmo Ruohonen, CEO of ZenRobotics.

We are very pleased to be able to help place the first ZenRobotics facility in Denmark, which is also the first robotic sorting line for this type of waste in Denmark. Artificial intelligence is at the core of the facility, meaning that Solum will now get much more out of sorting their waste than before. A robot plant will help to revolutionize waste sorting, not only at Solum, but potentially throughout Denmark.
