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.
The building industry is incredibly conservative. There will be doubts with this about its durability - nobody wants to have to build something again.
To add to this. If a company builds with this new material and it turns out there’s some unexpected issue with the material, the company will be held liable for the damage. They can shove that liability back on the product manufacturer, but only so many can do that before the manufacturer just shuts down. Then the construction company has to foot the bill of a new building, which they can’t afford, and thus shut down.
I absolutely hate how conservative the building industry is, but it’s a culture that’s been born out of harsh lessons and loss of livelyhoods.
Good point, thanks.
