Recently at work while doing some run-of-the-mill materials research I came across a completely non-run-of-the-mill range of carpet tiles that utilises Biomimicry and a unique lesson from nature to achieve sustainable innovation.
Traditionally carpet tiles are required to be identical in colour, pattern, size and must be installed uniformly in the same direction. This necessity for perfection has often led to large amounts of pre-consumer product wastage. Interfaceflor teamed up with Janine Benyus and the Biomimicry Guild to observe nature, taking inspiration from the forest floor and challenging these pre-existing assumptions and methodologies.
By observing the ‘organised chaos’ of the forest floor and the imperfect pattern that the different leaves and plants made, it was found that visually pleasing patterns could be made from patterns that were similar but not identical. Applying this to carpet tile design means that batches with slight imperfections, such as differing dye tones, can be harmoniously integrated into an overall flooring design where previously they would be discarded. This effectively reduces wastage at the manufacturing stage, and by introducing a new modular system that does not require carpet tiles to be identical in size, wastage is also avoided at the installation stage.
“in the industrial world, variation has traditionally been seen as imperfection. Using Biomimicry, Oakey was able to incorporate our natural admiration of variation into an industrial process that was traditionally intolerant of it”. –Interfaceflor
Of course there is more to sustainable flooring than producers reducing their wastage (and equally their financial losses). Carpeting is one of those building materials with an especially bad reputation for high embodied energy, short lifespan, high landfill presence, and a high possibility of poisoning you at your desk by VOC off-gassing.
Interfaceflor and the Biomimicry Guild attempted to tackle this problem of toxic glue reliance by studying the way Gecko’s feet adhere to surfaces. However this was leading them down a high cost path of technology research and development so they switched focus. Instead of asking the question “how does nature make glue?” they began to ask “how does nature keep a surface in place?” The answer is simply ‘gravity’, and with this new perspective on the problem the team was able to allow gravity to do its job and keep the carpet on the floor, and focus instead on the simpler task of keeping each carpet tile attached to the others in the modular. This ‘less is more’ approach found a low tech, logical solution in place of existing wastage or a potential high-tech high-cost solution.
There are so many things we do in building and construction which are an unnecessary overkill of outdated ideas that haven’t been challenged since they started turning a profit. One of the best benefits of Biomimicry is its ability to question assumptions and radically shift perception, as was done here in the case of carpet tiles. In particular the first two steps of the Biomimicry Design Spiral are crucial in achieving this, opening our eyes to the simple, logical solutions nature provides us with.
