The new Resursutvinning Stockholm MSW sorting plant, designed and built by STADLER Anlagenbau GmbH for Sweden’s largest water and waste utility, is a highly automated, high-throughput facility that supports Stockholm’s environmental strategy, enabling the efficient recovery of recyclable materials and organic waste while reducing CO2 emissions.
STADLER Anlagenbau GmbH, the globally active German company specialised in the planning, production and assembly of turnkey recycling and sorting plants, has successfully completed the new municipal solid waste sorting plant for Stockholm Vatten och Avfall (SVOA). Designed to process 50 tons of waste per hour, the new facility is equipped with fully automated sorting lines that recover organic waste from household garbage, as well as plastic and metals accidentally mixed in the residual material arriving at the plant. This reduces the volume of materials destined for incineration to generate power and heat water, consequently lowering CO2 emissions.
With its fully automated process and two parallel sorting lines that can operate independently, the facility brings resilience and efficiency to Stockholm’s waste management system. Commissioning was completed in August 2024 and the plant was officially inaugurated in October.
“The Resursutvinning Stockholm plant is a leap forward towards ambitious environmental goals while ensuring reliable, high-quality waste management,” said Lars Nyquist project manager at SVOA. “It is important that packaging is sorted at home, but plastic and metal packaging can accidentally end up in the residual waste. With STADLER’s expertise, we now have the technology and infrastructure to improve resource recovery, reduce emissions, and move closer to closing the loop on waste in Stockholm.”
At the heart of the facility is a state-of-the-art sorting process that separates green bags containing organic food waste, as well as any mixed plastics, ferrous and non-ferrous metals finding their way into the residual waste arriving to the plant – with a high degree of precision and automation.
The Resursutvinning Stockholm plant was designed with a focus on operational efficiency, the work environment, and safety. The equipment has been positioned on multiple levels to fit within the facility’s compact footprint, with a layout engineered for both accessibility and safety. All drives and maintenance points are accessible via walkways and dedicated platforms, ensuring that servicing can be conducted quickly and safely.
“What stands out in this plant is its adaptability,” adds Nejc Božič, Project Manager at STADLER. “Everything from the parallel line design to the movable conveyors under the screens gives SVOA the flexibility to handle seasonal variations, keep the line running and optimise performance with minimal manual intervention.”
The Resursutvinning Stockholm project embodies the highest standards of engineering, environmental stewardship, and customer collaboration. With STADLER’s support, SVOA is establishing a new benchmark in municipal waste recovery and progressing towards a circular economy.
