At Panchsheel Inter College in Uttar Pradesh, students now study inside a new school wing built not from concrete or traditional brick, but from sugarcane. The innovation was born at the University of East London (UEL) and its creators argue it could reshape how buildings are made and how the planet pays for it.
Sugarcrete combines the fibrous residues of sugarcane, called bagasse, with sand and mineral binders to produce lightweight, interlocking blocks. Lab tests show that Sugarcrete has strong fire resistance, acoustic dampening, and thermal insulation properties. It’s been tested to industrial standards and passed with flying colors. In terms of climate impact, the material is a standout. It’s six times less carbon-intensive than standard bricks, and twenty times less than concrete, by some estimates.
Yet the real excitement doesn’t only come from what Sugarcrete is, but how it’s made and used. It is purposely ‘open access’ in order to establish partnerships to produce new bio-waste-based construction materials where sugarcane is grown. Unlike conventional building materials locked behind patents, Sugarcrete can be made by anyone with the right ingredients and basic manufacturing tools. That choice decentralizes construction innovation, allowing small-scale producers — especially in the Global South — to lead.
Probably because there are no long-term tests yet. You can build a house out of dried cow shit if you really want, but is that building still standing in 25 years? We don’t know yet and no company wants to be liable for damages if the houses they’ve built are falling apart. And in heavily regulated countries like germany, they all have to be approved by the government which will take even more time.
