May 5th, 2021 the new RecoLab testcentre in Oceanhamnen, Helsingborg has been inaugurated. RecoLab accommodates an innovative waste and wastewater treatment system for around 320 apartments and several office buildings, amounting to around 1800 people equivalents.
Toilet wastewater (black water), organic kitchen waste and other domestic wastewater (grey water) will be separately collected and treated, aiming for maximum resource recovery. 

With this new sanitation design, DeSaH already won the Swedish innovation prize in 2015 in the "Blackwater and Food Waste Challenge" in the category "Treatment plant", aimed at the recycling of waste streams. The jury report states: "DeSaH has developed a compact wastewater treatment plant, a concept that contributes to an increased recirculation of water, nutrients and energy."

Desah received the order to realize the sanitation system, emphasizing the recovery of valuable raw materials such as fertilizer and biogas, as well as heat recovery.

Desah is responsible for:

  • Digestion of toilet water (black water)
  • Digestion of food waste
  • Hygienization of sludge
  • Gray water treatment
  • Heat recovery


  • NSVA (North-West Skåne’s Water and Avlopp AB)
