Meta deal will help plastics recycling startup MacroCycle build its first factory

Plastics recycling startup MacroCycle announced a new deal with Meta on Tuesday that will help speed the development of its first commercial plant. Three-year-old MacroCycle, based in Cambridge, Massachusetts, has developed a novel way to process plastic waste that strips it of contaminants, making the resulting recycled material more attractive to customers. The startup says its technology generates 80% fewer carbon emissions than new, non-recycled virgin PET plastic (a common type of plastic used in bottles, containers and textiles). MacroCycle was a Top 20 finalist in the 2025 Startup Battlefield competition at TechCrunch Disrupt in San Francisco.
