New materials from grinding dust and side streams – even closed-loop abrasive products

Could the sanding dust generated from sanding wooden surfaces be used as a raw material for new materials and products? Abrasives manufacturer Mirka, which aims to promote responsibility and reduce emissions, has launched a new co-development project with its partner network. In the best case scenario, sanding dust can be processed into materials that can be used in the manufacture of products used for sanding itself. One of the goals of the From Dust to Value project, which was launched in December, is to develop such closed-loop products from sanding dust. In addition, the partners are looking at how other wood-based side streams and waste materials could be utilized, such as sawdust or bark generated in processes in the forest industry and wood products industry. Part of the SHAPE ecosystem Mirka is known for its solutions that support dust-free sanding and promote occupational health, in which sanding dust is collected and does not enter the respiratory air. When renovating and sanding wooden surfaces, fine, wood-based dust is generated. Mirka began to consider whether this dust could be used as a raw material. The path to co-development opened up through the five-year SHAPE ecosystem launched by Mirka in early 2023 with the support of Business Finland. Mirka acts as a driving force in the SHAPE ecosystem, where the goal is to extend the service life of products, develop more sustainable products, and at the same time reduce the total...
