ByBlock® is an innovative construction material produced by ByFusion’s proprietary process, transforming unsorted, non-recyclable plastic waste into high-strength modular building blocks. Through a carbon-neutral and zero-waste method, mixed plastics—including marine debris and household plastics—are compressed using steam into uniform blocks without additives, adhesives, or fillers. Each ByBlock contains one ton of plastic, matching the original material weight, and reduces CO₂ emissions by approximately 83% compared to conventional concrete blocks. ICC-ES listed and UL EPD certified, ByBlock meets rigorous performance standards suitable for various applications including perimeter walls, sheds, seating walls, landscaping, and structural enclosures. Available through walling kits and commercial diversion services, ByBlock offers an accessible, drop-in alternative for both professional builders and end-users. It supports circular-economy principles, turning problematic plastics into long-lasting, climate-friendly infrastructure elements.
