Microorganisms can biodegrade PP when it contains P-Life. Significant decomposition marks were observed on the surface of the P-Life PP straw compared to the conventional one.
TOKYO, May 17, 2026–(BUSINESS WIRE)–P-Life Japan Inc. has identified and verified groundbreaking scientific evidence demonstrating the microbial bioassimilation of plastics enabled by its proprietary P-Life technology.
Each year, the world produces nearly 400 million tons of plastic, and close to half of it is designed for single use. An estimated 11 million tons end up in the oceans annually, where they can persist for centuries. The challenge has never been simply about recycling — it has been about physics, chemistry, and biology. Conventional plastics like polyethylene (PE), polypropylene (PP), and polystyrene (PS) are chemically stable hydrocarbon polymers. They resist water. They resist microbes. They resist time.
Recent findings, however, indicate a shift in this dynamic.
In a breakthrough collaboration between Keio University, ITO EN Ltd., and P-Life Japan Inc., scientists have identified and verified the specific microorganisms — and their associated genetic pathways — capable of biologically decomposing conventional plastics treated with P-Life technology. This is not fragmentation. This is not oxidation alone. This is true microbial biodegradation in real-world environments — soil and marine ecosystems — confirmed through international testing standards and direct microbiological evidence, eliminating microplastics.
A Scientific Turning Point
The fundamental question has always been: Can conventional plastics return to the natural carbon cycle?
P-Life technology works at the molecular level. Derived from plant-based fatty…
