Used chopsticks are being converted into furniture, while food waste can be redeployed as construction material. And don’t forget about sugarcane.
A London-based research team mixed the crop’s fibrous waste with a liquid blend of minerals, then pressed the material into pyramid-like blocks.
These can be cured in a week, 21 days fewer than standard concrete. Moreover, they are five times lighter, robust, flame-resistant and equipped with thermal properties.
Making them perfect as insulation panels, lightweight blocks or structural floor slabs. Assembled in an interlocking structure, they can be taken apart and reused.
Best deployed in places where sugarcane is already cultivated to reduce CO2 emissions and save on transport costs.
Coconut shells are doing their bit there too.
