PHAs will biodegrade, so applications are focused on products with known life cycles or products that will be protected from biodegradation triggers.Production of PHA is currently limited.New production capacity is being announced by suppliers.

Rate of biodegradation can be modified by the resin producer.PHAs can be molded by typical plastics forming processes.

PHA technologies vary and include using diverse feedstocks including inexpensive plant oils such as those pressed from canola and soy seeds to r aw biogas containing methane, carbon dioxide, and hydrogen sulfide, to recycled cooking oil. PHAs are polyesters that are biosynthesized by bacterial fermentation using a range of bioderived feedstocks. Here is a brief overview of both materials to help start the discussion within your organization. PHA is biodegradable, while PEF can be recyclable. Each is made by completely different processes, but both can be biobased. Polyhydroxyalkanoates (PHAs) and polyethylene furanoate (PEF) are two of those intriguing bioplastics. However, with the demands for reduced carbon footprint continuing to grow in importance amidst significant concern about the availability of rPET, brand owners should also be considering an alternative to fossil-fuel-based plastics. The material is known for is robust recycling stream and ability to be reprocessed into rPET for subsequent generation usage. When the subject of sustainability and recycling comes up, the discussion focal point for packaging is frequently polyethylene terephthalate (PET).
