Summary

Our world is overwhelmed in plastics pollutions. Concerns about environmental issues and news related to microplastic pollution inspired us to start this project. our mission is to degrade micro/nano-plastics (PET) in the water body by genetically modified E.Coli biodegradation system that produces PETase and strengthens the biofilm system. This combined biodegradable system can not only degrade PET plastics but also attach degraded microplastics, so it will not flow away, thereby preventing it from further pollution. Our product would be environmentally safe and biodegradable. We surveyed the general public as well as professional workers so that we can have the best understanding of our project. By understanding our parts and going through experiments, we created the best outcome of the project, and our mission is on the way.
