We developed a microbial cocktail that degrades, metabolises and mineralizes fossil based plastics. Our process is applicable to all sorts of single-use plastics (PET, PP, LDPE, HDPE, PS, CPE, EVA -all tested) and can operate under suboptimal conditions. we have tested these plastics separately and mixed in together as well. The listed plastics are post-consumer waste plastics: colored, clear, sterilized and plastics with food debris on them. This method not only solves the plastic issue but also generates valuable end-products: bioplastics and biogas. With these, our aim is to create a circular, thus more sustainable economy. The process itself can be described as follows: we take a blend of hydrocarbon based plastics, put them in a batch with the bacteria, our minimal essential media and water. Afterwards in about two days we can macroscopically confirm the beginning of the degradation process. Complete degradation of the polymers will take about two months.
