Resumen:
Fossil fuels are a major source of energy worldwide and serve as raw materials for the production of plastics. However, they have disadvantages such as uneven distribution, price instability, limited availability, and environmental impact. Consequently, there is a need to find alternatives to fossil fuels for both energy and polymer production in the short term. This review focuses on the synthesis of poly(hydroxyalkanoate)s (PHAs), a type of biopolymer, using different bioethanol stream wastes. PHAs exhibit properties comparable to petroleum-based plastics, making them promising replacements. There has been a significant increase in research studies exploring alternatives to fossil fuels and synthetic polymers, as evidenced by the growing number of publications. While biopolymers currently account for only 1% of global polymer production derived from petroleum, the PHA industry is experiencing rapid growth. The market value of PHAs was estimated at $ 168.9 million in 2020, and it is projected to reach $ 440 million by 2031, indicating a compound annual growth rate of 9.2%. The production of this biopolymer is already contributing to an expanding industrial value chain, which is expected to further growth with increased availability of commercial PHAs.
