Sustainable Products, Projects and Green Design Carbon Activated Timber Bench by Michael Budig Carbon Activated Timber Bench is designed for public areas and is made from reclaimed wood planks. It challenges the notions of weight and stability. While the volume of the wood planks appears as seemingly massive blocks, they are only loosely connected and in an unstable state. Tiny threads of carbon fibres tie the massive blocks together to give them their stability. They also reinforce the blocks to even add strength to the wood planks.
