Flood-resilient building blocks made completely from recycled plastic
Marie Donlon | January 13, 2026WES-Tec Global, a construction technology firm, has created building blocks that tackle both plastic pollution and climate-driven infrastructure risks.
According to its developers, the ECOCCUBE system transforms waste plastic into durable building blocks for use in vulnerable environments, offering a sustainable alternative to conventional concrete.

The team envisions that the blocks will offer a solution that targets coastal erosion, flooding and structural instability while simultaneously addressing plastic waste.
The core material that makes up the ECOCCUBE system is 100% recycled waste plastic. The company uses a proprietary process dubbed Newcycling to create the plastic-waste derived building blocks.
Newcycling, which is performed in a dedicated New-Cycle Factory where the discarded plastic is turned into construction-grade blocks, reportedly preserves the physical properties of plastic while also enabling new structural uses. Further, the Newcycling process accepts mixed plastic waste — unlike traditional recycling systems — and sorting and washing are not required.
Capable of achieving a compressive strength of 26.4 MPa and a tensile strength of 16.7 MPa, the blocks are designed for demanding environments, such as coastlines, rivers and sloped terrain, supporting shoreline reinforcement and flood-resilient infrastructure and protecting against erosion, earthquakes and tsunamis.
Additionally, each kilogram of ECOCCUBE reduces carbon emissions by 2.99 kg CO2, or about 6.6 lbs of CO2, according to lifecycle assessment data.
Specifically, one 25 kg unit — about 55 lbs — results in a 74.69 kg CO2-equivalent reduction, which is equal to roughly 165 lbs of CO2.
