Every year, 15 Billion trees are cut down to produce paper, build homes, and make furniture. From this, millions of tons of wood waste are generated annually. A portion of this waste is recovered and sold to downstream markets to make particle board or wood pellets for energy. The remaining sawdust is either burned – contributing to air pollution – or sent to landfill. Though biodegradable, sawdust can be harmful to the environment in large quantities when landfilled. As it decomposes, sawdust releases high concentrations of lignin and fatty acids, which can contaminate water supplies, potentially poisoning wildlife and micro-organisms. We speak with Andrew Jeffery, Co-founder of Forust, by Desktop Metal, uses the power of high-speed, high-resolution 3D printing to give a new life to a discarded resource – creating strong, beautiful and carbon-friendly wood products from wood waste. For each tree saved, we reduce the CO2 footprint by a metric ton over the tree’s life. Learn more in our next episode.
