Unique sustainability initiative behind storage of road salt in the Port of Södertälje

9 October 2023 Inter Terminals Sodertalje tank storage terminal

Together with the mineral distributor GC Rieber Salt, the logistics company Inter Terminals Sweden will store calcium chloride at its facility in the Port of Södertälje. The calcium chloride, which will be used for dust control on gravel roads and for industrial purposes, is extracted from fly ash using the environmental company Ragn-Sells’ Ash2Salt technology.


“We aim to be the most sustainable mineral distributor in the Nordic region, and with this project we are going from words to action. We look forward to working together with Inter Terminals and Ragn-Sells in a collaboration that will enable us to offer calcium chloride with a significantly lower climate footprint. Circular salts represent an important step towards achieving a society without net emissions and reducing the use of fossil products”, says Per Gunnar Syrdalen, Marketing Director at GC Rieber Salt.


As part of the transition towards fossil-free flows, Inter Terminals will offer calcium chloride storage and logistics services to the Nordic mineral distributor GC Rieber Salt at its facility in the Port of Södertälje. The calcium chloride is extracted from fly ash using the environmental company Ragn-Sells’ innovative “Ash2Salt” method and will be used in circular flows and new products. The project goes by the name “Salt-i-Tälje” and will commence in the autumn of 2023 with the redevelopment of Inter Terminals’ facility for adaptation to the storage of calcium chloride mixed with water. Inter Terminals’ facility in the Port of Södertälje will store 5,000 tonnes of product, with the start of operations planned for April 2024.

“The Salt-i-Tälje project is completely in line with our strategy of playing a leading role in the green transition in our industry, and working with recycled materials is a completely new and very interesting segment for us. We are full of enthusiasm at the prospect of being able to implement this project together with GC Rieber Salt and other parties”, says Johan Zettergren, Managing Director of Inter Terminals Sweden.

Efficient technology with multiple benefits
Around 300,000 tonnes of fly ash are produced in Sweden each year in connection with the cleaning of flue gases from waste incineration. The ash contains large amounts of valuable raw materials such as potassium, sodium and calcium in salt form. These salts are extracted at Ragn-Sells’ Ash2Salt facility in Bro, just outside Stockholm, while environmental toxins are removed at the same time. The calcium chloride is used, among other things, for dust control on gravel roads.

“If we are serious about creating a sustainable society, we need to make it easier for as many businesses and people as possible to use recycled raw materials. It is therefore extremely positive that recycled salt from the Ash2Salt facility will be able to reach a larger customer base through transshipment to ships”, says Jonas Wibom, Business Development Manager at Ragn-Sells Treatment & Detox.

Per Fredman, Deputy CEO of the Port of Södertälje, has the following comment regarding the initiative:

“The Port of Södertälje strives to achieve long-term sustainable development for people, the climate and the environment. We feel very positive about the fact that one of our customers is contributing to a sustainable transition and that an environmental problem can be turned into a sustainable alternative for making roads less dusty in the summer.”
