TOKYO--(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.<\/p><\/a><\/a><\/a><\/a>

\nEach 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 \u2014 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.<\/p>

\nRecent findings, however, indicate a shift in this dynamic.<\/p>

\nIn a breakthrough collaboration between Keio University, ITO EN Ltd., and P-Life Japan Inc., scientists have identified and verified the specific microorganisms \u2014 and their associated genetic pathways \u2014 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 \u2014 soil and marine ecosystems \u2014 confirmed through international testing standards and direct microbiological evidence, eliminating microplastics.<\/p>

\nA Scientific Turning Point<\/b><\/p>

\nThe fundamental question has always been: Can conventional plastics return to the natural carbon cycle?<\/p>

\nP-Life technology works at the molecular level. Derived from plant-based fatty acid salts, the additive initiates controlled radical reactions within the polymer matrix, transforming high-molecular-weight hydrocarbon chains into lower-molecular-weight compounds enriched with functional groups such as carbonyl (C=O) and hydroxyl (\u2013OH). These structural changes are critical. They convert inert plastic into compounds that microorganisms can metabolize.<\/p>

\nThis mechanism has been validated under internationally recognized standards including ISO 17556 and JIS K6955, demonstrating over 80\u201390% biodegradation in soil environments within defined testing periods. Carbon conversion to CO\u2082 was directly measured, confirming final microbial mineralization \u2014 not mere surface erosion.<\/p>

\nBut the most decisive evidence goes further.<\/p>

\nPlastic-Eating Microbes Identified and Characterized<\/b><\/p>

\nThrough the \u201cReturning Straws to the Earth\u201d field project in Kamakura, Japan, P-Life polypropylene straws were buried in soil under controlled observation. Electron microscopy revealed dense colonies of bacteria attached directly to the plastic surface. Clear biodegradation marks were visible. Subsequent microbial analysis identified key strains including Cupriavidus sp., Camelimonas lactis, and Bacillus sp.<\/p>

\nFurther marine studies conducted by Keio University identified more than 70 bacterial strains in seawater environments \u2014 including Alcanivorax sp. \u2014 actively colonizing and degrading P-Life-treated PE and PP films. Significant weight reduction and surface degradation were observed in treated plastics, while untreated PE and PP showed no comparable microbial activity.<\/p>

\nFor the first time, the organisms \u2014 and their genetic signatures \u2014 responsible for degrading these modified conventional plastics have been isolated and characterized. This isolation and characterization marks a significant advancement in the scientific understanding of plastic biodegradation.<\/p>

\nCO\u2082, Circularity, and the Carbon Question<\/b><\/p>

\nA critical concern in today\u2019s sustainability debate is carbon emissions. What happens to the carbon embedded in plastic?<\/p>

\nThe answer is grounded in microbiology. When microorganisms metabolize the transformed polymer fragments, part of the carbon is used for cellular growth and biomass formation, and part is released as CO\u2082 through natural metabolic pathways \u2014 the same process governing decomposition of organic matter in ecosystems.<\/p>

\nRather than persisting for centuries as inert waste, plastic treated with P-Life technology re-enters the biological carbon cycle through microbial metabolic activity.<\/p>

\nP-Life technology bridges synthetic polymers back into natural ecological systems, enabling full biological carbon cycling rather than surface-level fragmentation.<\/p>

\nThis has profound implications for:<\/p>
