MIT spinout Atlas turns plastic waste into building materials with AI robotics
MIT News AI · rss · 2026-09-14
MIT spinout Atlas Building Composites has built an AI-powered robotic manufacturing platform that turns single-use plastics into building materials stronger than wood.
How it works
- Born from MIT's HAUS research effort; uses a waterless recycling process plus large-format composite 3D printing. Shredded bottles are melted and fused with US-made fiberglass, then printed into home foundations, decks, and trusses for floors, walls, and roofs.
- Waterless recycling is key to global scale: no local water permitting needed, so any country can host local recycling-plus-factory cells.
Traction and numbers
- Parts already support barns, sheds, decks, and docks; supplied the US Army Corps of Engineers with trusses for a 40-foot bridge in a Massachusetts wetland, installed in under a day.
- Lab demonstrations: large composite trusses printed in under 13 minutes, supporting over 4,000 pounds, exceeding key building standards. Throughput of 60–80 lbs/hour in lab, 150–200 lbs/hour for planned factory systems, potentially cheaper than injection molding.
- Each factory cell produces structural framing for about one small home per day. Co-founder A.J. Perez aims to build 1 billion homes over 30 years and is in talks with international franchise partners for localized deployment.
