The COM4PHA project, a collaboration between the Spanish government, industry, and research, is developing new formulations of bioplastics for packaging and coatings based on polyhydroxyalkanoates (PHAs). These biodegradable materials are produced by microorganisms and offer a viable alternative to conventional petroleum-based plastics used in packaging and agriculture.Currently, PE films are widely used in agriculture to boost crop yields, extend growing seasons, reduce the need for pesticides and herbicides, and conserve water.
