Boliden has signed an agreement for the production and delivery of a newly developed explosive with significantly improved environmental and climate performance. As a result, the need for nitrogen treatment of water is strongly reduced and climate performance is improved by around 400 tons of CO2 per year. As the first mining operator, Boliden has signed an agreement with the Swedish explosives supplier Hypex Bio regarding the production and delivery of nitrate-free and environmentally friendly explosives to Kankbergsgruvan, Boliden.

The agreement means that Boliden and Hypex will cooperate on the production and delivery of nit rate-free and environmentally friendly explosives To the Kankberg mine, which includes the establishment of a production facility at the mine as well as a delivery and service agreement. The supply and service agreement for Hypex's explosives solution spans five years starting in 2024. The production quantity is expected to amount to 400 - 450 tonnes and thus largely meet the Kankberg mine's annual needs.

In addition to the fact that the explosive drastically reduces the need for nitrogen treatment of Water, the climate impact is reduced by approximately 400 tons of CO2 peryear (Scope 3). The collaboration between Hypex Bio and Boliden has been ongoing since 2020, where the nitrate-free explosive has been developed and tested in the Kankberg mine. The technology has proven to meet Boliden's requirements for safety, performance, environment and reduced carbon dioxide emissions.

Tests have also been carried out in the Garpenberg mine and are to be started in the Aitik copper mine.
