Sweden’s Höganäs AB has reported that Petrit E, a product made from residual material generated by its atomising plant in Halmstad, is now used in the production of stone wool. Sales volumes are expected to double during the coming year, states the metal powder producer.
Petrit E is made from slag from the arc furnace in Halmstad, Sweden. The furnace generates around 13,000 tonnes of slag each year. Expectations are that most of it will be sold as Petrit E for stone wool production.
Petrit E contains some iron oxide which makes it well suited for the production of stone wool as it makes the wool more resistant to fire.
“Last year we delivered around 5,000 tonnes of Petrit E for mineral wool production,” stated Björn Haase, Manager Non Metal Products. “We believe we will be able to double that number this year. For Höganäs the benefits of Petrit E are several; there is a sales revenue, and we also save money by not having to dispose of the slag. We are one step closer to our vision of generating Zero Waste.”
