Swedish municipal energy company Bollnäs Energi AB is the latest to select Ragn-Sells for the treatment of fly ash from its energy production. Currently under construction, Ragn-Sell’s Salarium Högbytorp in Upplands-Bro, northwest Stockholm will have the capacity to process around 150 000 tonnes per annum of fly ash to recover commercial grade industrial salts while detoxifying the residual material when it enters operations later this year.

Fly ash is formed when the flue gases from combustion are purified in flue gas treatment systems. The fly ash can contain elevated levels of substances that are harmful to health and the environment along with large amounts of valuable resources such as potassium, sodium, and calcium.

Proprietary Ash2Salt technology

Ragn-Sell’s new Salarium Högbytorp is currently being built in Upplands-Bro northwest of Stockholm. The process is based on the proprietary Ash2Salt technology developed by Ragn-Sells Group subsidiary EasyMining Sweden AB, and the new facility will be put into operation during the second half of 2022.

Ragn-Sell’s new Ash2Salt plant is a good example of how we can use raw materials over and over again in an increasingly circular economy. We are pleased with the great interest in the technology and can state that the facility is being filled even before we have opened the gates, said Mikael Hedström, CEO of Ragn-Sells Treatment & Detox.

Once fully operational, Salarium Högbytorp will have the capacity to process 150 000 tonnes of fly ash annually. This corresponds to approximately half of all fly ash that Swedish waste-to-energy players produce each year.

We are very positive that it is now possible to use the fly ash produced in our facilities as a resource, said Mikael Strandberg, CEO of Bollnäs Energi.

Framework agreement

Bollnäs Energi’s procurement has been carried out through a framework agreement between Ragn-Sells and the Swedish Purchasing Center for Infrastructure (Sinfra). Sinfra works to make it easier for its members to choose sustainable solutions.

Thanks to the framework agreement, it is now possible for all Sinfra’s combined heat and power (CHP) members to choose a sustainable solution for the management of their fly ash by call.

Sinfra’s main task is to make it easier for our members to procure sustainable solutions. Ragn-Sell’s new solution for fly ash, Ash2Salt, is an excellent example of how our framework agreements can contribute to a sustainable society, said Tony Doganson, CEO of Sinfra.
