Metal isn’t always needed to make knives. Sustainable pallets can be made from tropical materials.

Students from Karnataka in India are hoping to substitute steel in house constructions after integrating a bamboo net into a spherical stone shell.

They discovered that this material can be used to make lightweight slabs that can nevertheless carry weights of up to 700 kg.

The slabs are earthquake- and weather-proof, and don’t rust. Large-scale production will not only ease the financial strain on home builders but help save the environment.

Manufacturing a single tonne of steel releases 2.4 tonnes of CO² into the atmosphere. Growing more bamboo plants, meanwhile, could bind more of the gas from the air.

Building a better future.
