When talking about climate impact there are two aspects:
Nowadays, most of the left-over sawdust is being burned or turned into wood pellets. Studies show that burning biomass (incl. sawdust & wood leftovers) emits more carbon per unit of energy than most fossil fuels. E.g. burning oil releases 377 kg of CO2 while burning woodchip releases 1501 kg of CO2per MW h delivered energy. The best outcome for the climate in the short and long term is not to burn it, but to use it for wood products. Turning sawdust into a sustainable material and creating higher value products out of it makes it possible to save tonnes on CO2 from being released to the atmosphere.
Secondly, 88% of all the materials used in 3D printing industry are plastics. Printing with plastic releases toxic fumes and particles in the air. Only 15% of all the world’s plastic is recycled. There is no sustainable 3D printing material on the market. It is not possible to print with wood. Our goal is to reduce the use of plastics as the main 3D printing material by 50% with our innovative sawdust-based material, which can be turned into long-lasting products that bind carbon for decades. Replacing one cubic meter of plastic with timber helps to save 1000 kg of CO2 from being released to the atmosphere (when talking about sawdust, this number is even higher).
