Our research team, consisting of Keio University, Ito En, Inc., SI Resin Industry Co., Ltd., and the Keio University Advanced Molecular Science and Technology Research Center, has successfully obtained a degradation bacterium for polypropylene (PP) that incorporates the additive "P-Life," which imparts biodegradability to plastics. This research achievement represents an important step towards the microbial degradation treatment of non-degradable polyolefin-based plastics. Furthermore, the degradation bacteria attracted by the addition of P-Life are expected to effectively decompose and remove microplastics generated from polyolefin-based plastics, helping to alleviate their accumulation in the global environment. 【Features】 - Multiple degradation bacteria discovered that are compatible with P-Life added plastics - Capable of degrading a wide range of materials, including polypropylene and polyethylene - Safety of metabolites produced after plastic degradation by microorganisms - Effectiveness of P-Life in promoting microbial degradation has been demonstrated *For more details, please refer to the materials.

We would like to introduce the shelf life of our microbial biodegradable plastic additive, "P-Life." Knowing the product's lifespan is very important when dealing with microbial biodegradable plastics in general. The shelf life of the product is defined as the period until decomposition begins. 【Method for Measuring Shelf Life】 1. Conduct heat acceleration tests at 80°C in a gear oven for each product sample. 2. Confirm the point at which decomposition begins from the changes in the sample's properties. 3. Convert that time into the duration at room temperature storage to estimate the shelf life. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the decomposition mechanism of our microbial-degradable plastic additive, 'P-Life.' It has a mechanism that repeatedly undergoes oxidation and reduction reactions, utilizing this function to continuously induce and promote oxidative degradation by attracting radicals to the carbon chains of the polymer. The formed oxides (for example, carboxylic acids) are digested and absorbed by microorganisms in soil or compost environments. Ultimately, they are transformed into CO2 (carbon dioxide) and H2O (water) through metabolic activities such as respiration. 【Features】 ■ Possesses a mechanism that repeatedly undergoes oxidation and reduction reactions ■ Capable of continuously inducing and promoting oxidative degradation ■ The polymer is depolymerized into low molecular weight compounds, forming oxides (functional groups) *For more details, please refer to the PDF document or feel free to contact us.
