Creating circular plastics with zero carbon emissions.

The Tough Tech problem we are solving

Plastics manufacturing drives nearly 6% of global CO2 emissions, with minimal recycling, especially in the US, sending waste to landfills, oceans, or incinerators, worsening contamination, emissions, and climate impacts.

About our solution

MacroCycle's patented chemistry restores any-quality PET and polyester waste to virgin-like condition as a drop-in replacement. Using 80% less energy than traditional recycling, and runnable on renewables, it enables fully circular, zero-carbon plastics without a green premium.
