To be able to upcycle wood waste into new concrete products the specific waste fraction must be subjected to several processes and quality assurance tests and analyses. Through a long trial process, we have amassed a lot of experience as well as specific knowledge about handling, processing and documentation of wood waste.
For the project Copenhagen Towers in Ørestad, Copenhagen, we have upcycled 60,000 linear metres of wood that otherwise would have been wasted. The wood comes from window frames, doors, floors and old scaffolding wood. The wood has been collected by our collaborator who has localised and categorized the material, so we can trace the wood back to its source.
Window frames and doors have been split in such a way that the wood can be planed and cut into regular sized strips. The strips have then been sent to be fireproofed to be able to comply with the strict fire regulations for indoor cladding. The wood is fireproofed to class B, S1-D0 by using Burnblock, a 100% organic and nontoxic fire retardant.
The wooden stripes are mounted on a back plate in such a way that the wood strips create a varying surface. The mounted wood is then treated with natural paint that is toned with natural pigments. The finished panels are 500mm wide and come in varying lengths of up to 6000mm without any visible seams.
