Concrete is the third largest greenhouse gas emitter but even less known is how much sand is required to make it. Sand mining is responsible for ecosystem collapse through erosion, water outflows, and biodiversity loss. The shortage of sand has prompted researchers to replace it with more sustainable aggregates, but the previously unsolvable issue is that any additive that is not a cementitious material creates weak points, and results in concrete that fails compressive strength testing.

MAA’VA™ is developing regenerative, carbon-negative concrete aggregates from recycled plastic and manufacturing waste that outperform traditional aggregates — addressing a $900B+ global aggregates market — building a regenerative foundation from waste destined for landfills or incineration while advancing solutions to the river sand shortage crisis, water scarcity, climate change, and the global waste crisis simultaneously.
