Environmental company Ragn-Sells and its innovation company EasyMining have been named as one of nine finalists for the 2023 Curt Bergfors Food Planet Prize. Like in 2022, the selection jury recognises their technologies for recycling key fertiliser nutrients from waste. The eventual winner of the world's largest environmental prize will be announced on June 9 and receive a prize sum of 2 million US dollars.
– If we are serious about creating a sustainable society, we have to start using the raw materials we already have, over and over again. Many raw materials of critical importance exist in abundance in our waste but are never put to use. We are extremely proud that the jury once again recognises our efforts to recirculate nutrients from waste streams and prevent them from ending up in the wrong places in our ecosystem, said Pär Larshans, Director of Sustainability at Ragn-Sells.
Ragn-Sells and EasyMining were also selected as finalists for the prize in 2022. This year, the same entry is recognised: Three separate, patented methods for recovering and recycling the three main nutrients crucial to agricultural fertiliser. These technologies are known as Ash2Phos for phosphorus, Aqua2N for nitrogen, and Ash2Salt for potassium.
– Today's sourcing of these three nutrients is deeply problematic. Every year, its impact on climate change, pollution, and geopolitical issues grows. With our methods, we aim to contribute to a comprehensive reform of the entire global food system, said Anna Lundbom, Chief Marketing Officer at Ragn-Sells’ innovation company EasyMining, which has developed the technologies.
– Just over the last year, threats to the global food supply have grown as the war in Ukraine has escalated and climate change has led to agricultural challenges. Recycling agricultural nutrients is more crucial than ever to our ability to feed everyone without wrecking the planet, said Mr. Larshans.
The Food Planet Prize winner will be selected by a jury of world-leading food system specialists located on four continents, chaired by Professor Johan Rockström, Director of the Potsdam Institute for Climate Impact Research, and Magnus Nilsson, the Director-General of the Food Planet Prize. The winner announcement ceremony is scheduled to take place on 9 June 2023.
The Curt Bergfors Foundation was established in 2019 by the Swedish entrepreneur Curt Bergfors, founder of the restaurant chain MAX Burgers. The Curt Bergfors Food Planet Prize is now the world’s largest environmental award, aiming to accelerate the transition to sustainable food systems.

FACT BOX: Ragn-Sells’ and EasyMining’s circular nutrient solutions
Ash2Phos: The Ash2Phos process treats the ash from incinerated sewage sludge. The ash has a high concentration of phosphorus, iron, and aluminium, but also contains unwanted heavy metals such as cadmium. The high metal content is an obstacle for processing the ash with conventional methods. In the Ash2Phos process, sludge ash is treated in a wet chemical process for the recovery of phosphorus, aluminium, and iron as clean commercial products. Cadmium and other unwanted elements are separated for disposal.
Ash2Salt: When flue gas from waste incineration is scrubbed and filtered, fly ash is formed and captured. This ash is classified as hazardous waste due to high levels of pollutants but also contains several desirable compounds, such as potassium and sodium salts. In the Ash2Salt process, the fly ash is washed, and three commercial salts are extracted from the wash liquid: sodium chloride, potassium chloride, and calcium chloride. The ash residue that remains after the treatment does not have to be placed in special landfills for hazardous waste, and several industrial applications may be possible; research is ongoing.
Aqua2N: To prevent eutrophication, wastewater treatment plants remove nitrogen from sewage water. This is done using bacterial methods that release the nitrogen back into the atmosphere. The Aqua2N technology, by contrast, is a chemical method applied to the sludge liquor that is formed when water is separated from sludge solids. Here, nitrogen in the form of ammonium is captured by an adsorption chemical. Next, the captured ammonium is recovered in a conversion plant to be used as fertiliser, and the adsorption chemical is regenerated to be used again.
Detailed information about the Ash2Phos, Ash2Salt, and Aqua2N technologies can be found on the EasyMining website.
