Helsingborg's RecoLab Advances Circular Wastewater Management with Innovative Three-Pipe System

Helsingborg's RecoLab facility is pioneering a new approach to urban wastewater management by transforming wastewater and food waste into valuable resources. Operational since May 2021, RecoLab functions more as a production facility than a traditional wastewater treatment plant, featuring a treatment plant for source-separated wastewater, an innovation test bed, and an exhibition hall.

Central to this innovation is the three-pipe system implemented in the Oceanhamnen district, which separates black water, grey water, and food waste at the property level. This separation facilitates the creation of clean “end-of-waste” products and supports recycling of nutrients, energy, and heat. Norwegian company Jets supplies a vacuum technology system that efficiently collects black water with minimal water use.

Collaboration between the city of Helsingborg, businesses, construction stakeholders, and technology providers has been key to this project’s success. According to NSVA's Hamse Kjerstadius, these partnerships help revolutionize resource management and sustainable urban development. Project manager Dennis Kerkhof emphasizes that investing in such solutions reduces environmental impact while opening opportunities for new business models. RecoLab also serves as a hub for international knowledge exchange, hosting delegations that study its practical applications.

Amanda Haux, business developer at RecoLab, highlights aspirations for broader adoption, stating that the technology and systems are ready for implementation in other cities, marking the beginning of realizing wastewater's full resource potential.

As Helsingborg continues to integrate this advanced system, the initiative sets a benchmark for sustainable urban water management and circular economy practices in Sweden and beyond.
