Coffee grounds are a key ingredient in sustainable concrete, while tiles made from eggshells are perfect for naturally-made interior fittings.
Corn cobs, too, can help reduce CO2 emissions in the building trade. A Dutch startup shreds dried corn waste and presses the scraps mixed with binding agent into panels at temperatures of up to 150 degrees.
These panels are cut into smaller tiles and covered with a biobased waterproof coating. The addition of biological particles after shredding helps create different colours.
The power for pressing is drawn from the production facility’s own supply of solar energy.
Tomato waste could be used as a plant-based alternative for the coating. And how about these containers made from popcorn to pack them?Â
