"If we are serious about creating a sustainable society, we need to start using the raw materials we already have as often as possible. Making use of the salts in fly ash so that they can be reused is a great example of this", says Mikael Hedström, CEO of Ragn-Sells Treatment & Detox Sweden.

Ragn-Sells' new Ash2Salt plant is being built in Upplands-Bro outside Stockholm and will be operational in the second half of 2022. The Ash2Salt technology means that operators of waste incineration plants can now choose a circular alternative for their fly ash instead of opting for landfill.

GC Rieber puts recycled salt on the market

GC Rieber Salt will handle sales of all the recovered salt from Ragn-Sells – products with more than 90 percent lower carbon footprint than the same salts from traditional production.

"All GC Rieber's activities are characterised by a strong sense of responsibility towards society and the environment. Through the cooperation with Ragn-Sells, we can offer the market several different high-quality salts, with a carbon footprint that is one tenth compared to traditional production", says Fredrik Eide, Country Manager Sweden and R&D Manager GC Rieber Salt.

Fly ash is formed when flue gases from waste incineration are cleaned. The 300,000 tonnes of fly ash produced in Sweden each year contain large amounts of valuable raw materials such as potassium, sodium and calcium in salt form. With the Ash2Salt technology, developed by Ragn-Sells' innovation company EasyMining, as much as 400 kg of salt per tonne of ash can be extracted.



The salts sodium chloride or coke salt, potassium chloride and calcium chloride are used to produce plastics, glass, paper, soap, paints, fertilisers, and medicines. Salts can also be added to improve food, feed, fabrics, and construction materials or to combat slippery conditions and bind dust.
