Höganäs says that some of its metal powder residual byproducts could be used to make artificial reef structures.

According to the company, the byproducts, which have high surface complexity and contain lime, have been suggested as part of the EU’s LIFE Lophelia project, which deploys artificial reef structures in Kosterhavet National Park, in Sweden in order to help grow more coral.

‘The eye coral larvae is natural to our waters, but they need to attach to hard surfaces that protrude from the bottom in order to thrive and grow into coral reefs,’ said Anita Tullrot, project manager for LIFE Lophelia.

Höganäs says that 80% of its residual products are used as raw materials in new products, for example as soil improvers, asphalt raw materials and insulation.

‘I am constantly trying to find new uses for Höganäs' residual products as part of our efforts to contribute to a circular economy,’ said Björn Haase, who is responsible for Höganäs' work with residual products. ‘Being able to participate in and contribute to a better environment through this project feels very important and good.’
