Bio-degradation of polyhydroxyalkanoates (PHA) films in soil and lake environment

The use of petroleum-based synthetic plastics has led to a deleterious solid waste management especially in the form of marine debris and presents a major growing global pollution problem. In response to these issues, the application of biobased and biodegradable polymers as an alternative to synt...
