The Ticket That Ate the Trucking Day
A truck can deliver a load before lunch and leave its invoice stranded for days. Tread rebuilt its software around the humble scale ticket, then made a business of closing the gap between dispatch and getting paid.
Neocrete wants your concrete to cost less. The secret is in the ash.
The Auckland company is turning low-performing ash into a useful cement replacement. In Brunei, its first scale customer reports lower carbon and a US$6 saving on every cubic metre.
Inside Quebec’s Million-Tonne Scrap Loop - and the Mill Closure That Explains Modern Steel
A century-old Quebec steel chain turns local scrap and iron into bridges, truck springs and even guitar strings. Its playbook is integration, patient modernization and low-carbon experiments - plus the uncomfortable discipline to consolidate when a product line stops performing.
The Cement Startup That Stopped Trying to Replace Concrete - and Learned to Sneak Algae Into the Mix
Prometheus Materials spent years teaching microbes to make stone. Its more consequential trick was learning that the concrete industry did not want a revolution - it wanted a familiar bag of powder that could survive the batch plant.
Granite Construction
Granite Construction does not merely pave the road. It can quarry the stone, mix the asphalt, help redesign the job and then build it - a century-old loop now powering a $7 billion project book.
Furno Materials
Furno Materials is a California cleantech company rebuilding how cement is made. Instead of the mile-long rotary kilns that make cement one of the dirtiest industries on earth - roughly 8% of global CO2 - Furno builds compact, modular vertical micro-kilns (the 'Furno Brick') that run at more than 80% thermal efficiency, roughly double a conventional plant. The kilns burn gas-based fuels, eliminate NOx and SOx emissions entirely, cut fossil-fuel emissions by at least 70%, and can reach zero emissions on hydrogen - all while producing standards-grade Ordinary Portland Cement at the point of demand.
