Huge quantities of these materials get currently scrapped because there is a lack of knowledge, networks and technical infrastructures for reuse. A first technical challenge concerns the heterogeneity of the materials we target. Thin sheets of steel are typically profiled for strength, and coated with other metals or paint to prevent corrosion. This complicates the use of many of today’s typical tools for cutting and shaping sheets, for instance the use of lasercutters.

Another important barrier is the lack of trade in these materials. There is a need to better understand what quantities of materials are available where, and how these can be commodified to reach interested manufacturers.

Finally, there is the economic case to consider. Reused steel needs to compete with new steel from the heavily subsidised domestic and international manufacturers and this is not always easy.

To tackle these questions and to allow us to further investigate, we position ourselves as a manufacturer of end-user products. We focus on lighting fixtures and small furniture, and we prioritise collaborations with designers and architects. We complement our own production of goods with an offer in exquisite second hand furnishings. Through these efforts, Halfwerk aims to establish a robust model for circular metal reuse, inspiring broader adoption in the industry.

Halfwerk develops a system for the local reuse of sheetmetal from demolition and industry sources.
