MAA'VA™ is developing a proprietary sustainable carbon negative construction material, turning plastic and nonplastic waste into eco-material, advancing solutions to climate change crisis, waste crisis, global river sand shortage, water scarcity and rapid urbanization. Our eco-concrete can be used for both conventional and 3D printing construction. By optimizing 3D printing technology we can build environmentally friendly low cost housing with eco-concrete in one day for 1/10th of the construction cost and half of the construction waste.
