What Renasys does
Renasys is a Norwegian climate-tech scale-up headquartered in Førde, co-founded by CEO Christopher Sveen (formerly Head of Engineering at UBQ Materials) and Trond Melhus (formerly with Cubility). The company designs and deploys mechanical wastewater filtration systems targeted at municipalities and industrial water users, built around proprietary 3D wire mesh filtration media with adjustable micron ratings from 40μm down to 5μm. The units operate on differential pressure alone, require no chemicals, and are designed to recover solids from wastewater streams that the company then routes into downstream resource-recovery modules producing electricity, heating, cooling, and fertilizer outputs.
The company manufactures its filter media through a founding partnership with Haver & Boecker, a German industrial wire-weaving specialist, and brings in advisory support from former IVAR IKS CEO Kjell Øyvind Pedersen. Renasys monetizes its technology through a water-as-a-service leasing model in which municipal and industrial customers pay a recurring per-cubic-meter fee for treated wastewater rather than purchasing hardware outright, with deployment configuration that integrates hardware and downstream resource-conversion modules at the customer site.
The company positions itself within UN Sustainable Development Goal frameworks for clean water, clean energy, and climate action, and has made a Clinton Global Initiative commitment consistent with ambitions to scale internationally beyond its initial Norwegian municipal pilot with Sunnfjord.

Renasys product offering
Product offeringCore offering
Renasys designs, manufactures, and operates mechanical wastewater filtration systems for municipal and industrial use. The system uses proprietary 3D wire mesh filtration media (40μm to 5μm precision) and differential-pressure separation to clean wastewater without chemicals, processing 2–500 liters per second per unit. Delivered as a water-as-a-service subscription with autonomous controls and big data analytics, the system is plug-and-play installed into existing facilities, achieving regulatory compliance within weeks and converting recovered sludge into renewable energy and fertilizer resources.
Product overview
Renasys offers a unified mechanical wastewater filtration system comprising the core Filtration System unit (2-500 l/s capacity), specialized Filtration Media (3D construction, 40μm to 5μm), and Solution Controls (autonomous operations, big data analytics). The company delivers its technology through a water-as-a-service leasing model where municipalities pay for water cleaned rather than equipment. All components work together as a plug-and-play system that implements into existing facilities without chemicals, instantly increasing capacity and cleaning performance to achieve regulatory compliance within weeks.
