Polyhydroxyalkanoates (PHA), a class of naturally-occurring polyesters, are promising candidates for replacing petrochemical plastics in select applications due to their biodegradability and other desirables properties. This report outlines the production processes for PHA, evaluates the companies that own these technologies (project scoring), and provides cost estimates for plant construction and production. Additionally, the report explores carbon credits and implications for PHA adoption in various sectors including food packaging, consumer products, and medical supplies.
