Regenerating the built environment through circular materials

Company details

Humanity builds the equivalent of a city the size of Paris every five days — and by 2050, 2.5 billion more people will move to cities — driving unprecedented demand for concrete aggregates, the world’s second most used natural resource after water and the material that makes up about 75% of concrete. The built environment already consumes 50% of all extracted natural resources while accounting for one-third of industrial emissions, driving climate change, ecosystem destruction, and sand & gravel depletion three times faster than natural renewal. Sand mining destroys river ecosystems, collapses deltas, and fuels violent illegal mining.

At the same time, global plastic and industrial waste is surging — with billions of tons of material landfilled or incinerated and total waste volumes expected to double by 2050 — fueling a worldwide waste crisis.

MAA’VA™ develops regenerative, carbon‐negative concrete materials from recycled plastic and manufacturing waste — turning materials destined for landfill or incineration into high‐performance, lightweight, CO₂‐sequestering concrete aggregates that reduce water demand and advance solutions to river sand shortages, water scarcity, ecosystem collapse, climate change, and the global waste crisis simultaneously, addressing a $1T+ global aggregates market.

75% of concrete is sand and gravel that we steal from rivers and habitats
