A startup affiliated with the Massachusetts Institute of Technology says it has a single, unified approach to two stubborn issues: plastic waste and building materials. It even cuts water use, to boot.
Atlas Building Composites says it uses robotics and a waterless recycling method to convert discarded single-use plastics into structural components for homes and infrastructure.
Here's what to know
Rather than downcycling old plastic into low-value pellets, Atlas Building Composites makes products like decking, foundation elements, and truss pieces for walls, floors, and roofs.
According to MIT News, the startup, which spun off from the school, uses a robotic manufacturing platform powered by artificial intelligence to turn waste into durable building components. The company came out of MIT HAUS — short for Home Architecture for Universal Sustainability — in MIT's Department of Mechanical Engineering.
One defining part of Atlas' approach is skipping the wash phase that often makes conventional recycling water-intensive. It also uses lower-grade plastic that might otherwise be turned away.
Many recycling systems struggle to handle contaminated or mixed plastics, sending more waste to landfills or leaving it at risk of polluting waterways and oceans. Atlas is targeting a more practical end market by creating structural materials that people and businesses can use.

A.J. Perez, chair and co-founder of Atlas and an MIT research scientist, told MIT News the company wants to "build 1 billion homes."
"We're turning bottles into buildings," Perez said.
More background
The pitch is that this could shrink impacts from both construction and trash while reducing water use. As Perez told MIT News, "You can't divorce these things from each other."
Conventional homebuilding commonly depends on timber, mining, and refining, which can bring substantial financial and environmental costs. Turning discarded plastic into durable foundations, decking, and framing parts could cut down on these impacts.
Recycling a wider array of plastic waste could also reduce the amount that ends up burned, buried, or scattered across ecosystems.
Meanwhile, leaving water out of the process could also make new recycling sites easier to establish, particularly where water is scarce or where permits and infrastructure are expensive and slow to secure.
"This is key to democratizing recycling," Perez told MIT News. "Now, every country around the world, regardless of their water access, will be able to do something about their plastic."
What's being done?
Atlas says its materials are already being used in projects such as sheds, barns, decks, and docks. It also supplied the U.S. Army Corps of Engineers with American-made recycled composite trusses for a 40-foot bridge in a Massachusetts wetland, according to MIT.
In the longer term, Perez and Atlas co-founder Matt Pouliot picture thousands of Atlas robotic production systems running globally. That kind of rollout could help regions handle their own plastic waste and remake it into useful products instead of shipping it away or dumping it.
Where can I learn more?
Atlas is part of a wider push to get more out of plastic recycling, rather than treating it as a low-value afterthought. The stories below show why current systems often fall short and where more useful second-life applications are emerging:
• Across the U.S., only 5% of plastic was recycled in 2021 while production kept rising.
• At Virginia Tech, engineers are advancing plastic recycling breakthroughs.
• Scientists are turning PET bottles into components for supercapacitors, opening higher-value uses for plastic waste.
