Description: 

Ragn-Sells collects, treats and recycles waste and residual products from businesses, organisations and households. Ragn-Sells' innovation company EasyMining provides solutions for nutrient recovery:

  • extracting phosphorous from sewage sludge ash
  • extracting salts, such as potassium chloride, and detoxifying waste-to-energy fly ash
  • removing and recovering nitrogen from water flows with a high concentration of ammonium nitrogen.

The recovered nutrients can be used in fertilisers and replace virgin resources, contributing to a circular economy and the reduction of human-made climate change. The technologies are based on low energy need and a high detoxification rate.
