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.
Sugercrete?
Dude, CANEcrete was right there. It was right fucking there!
Also sugarcrete begs the question (before you read up on it) what happens when it rains?
Agreed canecrete has got to be it.
It’d probably be fine, it uses the leftover fibers, not literal sugar that dissolves. A layer of waterproofing that’d you’d use for an earthen home or earth ship would probably do the trick.
Scientists are not the most creative when naming their findings.
Counterpoint: the Hotwheels Sisyphus spider (warning: spider)
I just invented ShitCrete
Bro, CRAPcrete was right there!
Damn, I just patented Turdcrete
Ugh, Daviiid
Cananite has been around for 100 years.
School classsooms are lined with it in Australia.
Now, how much is termite prevention.
Its soaked in formaldehyde, like particle board.
I’d argue “canecrete” is too close to “concrete.” Close enough that it might invite trademark/customer confusion complaints from the concrete industry.
I’d argue that that argument is not good
Canecrete already exists, that’s why:

It’s all fun and games until Hansel and Gretel show up at your elderly grandmother’s sugarcrete house.
Or you hear Fraggle Rock music playing nearby
Don’t try to simulate this by adding sugar to concrete.
Nobody talks about the obvious so… can I lick it?
This is pretty cool and it makes me wonder if there are far north options for materials you could use such cattails/bullrushes or maybe in a little warmer areas less desirable wood like poplar
Cobb, then hempcrete. Rammed earth or CEB always an option as well.
There is hempcrete too
Reed Canary grass makes great cob. Hemp is another likely fibre.
Lots of strong natural fibers out there.
Taking a step back, what they’ve kinda done is taken wattle and daub (but not really) and worked it to industrial standards. And wattle and daub got used in all kinds of ways all over the world.
Obv wattle and daub to structural standards and firecode and such so that your building can meet modern specifications is actually quite a handy thing? But yeah there’s an overall myopia to steampunk-leaning researchers to focus on a singular feedstock instead of working to create a spectrum of materials based on local availability.
This is really cool! I really hope the bricks will behave well long term.
naughty bricks?
This article was written by ants.
Haha my first thought was those modern cars that have rat problems because they wrapped the wires in a plant based wrapping that rats enjoy
My motorcycle was made in 2000 and a previous owner added a headlight flasher module at some point. Some rodent crawled all the way up inside the bike and into the nose cone just to gnaw on the flasher wires. I have looked around and inside many places over the years but have never found any other bite marks.
i keep seeing promising new building materials, but why don’t i see them widely used yet?
The building industry is incredibly conservative. There will be doubts with this about its durability - nobody wants to have to build something again.
There needs to be processing, manufacturing, and other infrastructure built for the practical large scale implementation of any new technology. That takes time. Bureaucracy can make steps take even longer.
I think I’m on lemmy too much, I read the title as open source building material…
Construction sand is still going to be a bottleneck resource in the near future.
Cuba! Get on this!
I want my walls to be snozzberry flavored
Sounds like a nice material. :)

Very cool stuff
