Abstract
The substantial increase in greenhouse gas (GHG) emissions from industrialization and urbanization is the primary driver of climate change, presenting significant environmental and health hazards on a global scale. One major contributor to GHG emissions is the production and disposal of plastics, which are ubiquitous in modern life. Plastics, primarily used in packaging, pose significant environmental and health risks owing to their non-renewable nature. To mitigate these impacts, polyhydroxybutyrate (PHB), a bioplastic derived from microorganisms, has gained attention as a sustainable alternative. One effective method for PHB production is the utilization of agro bio-waste as a carbon source through bacterial fermentation. Additionally, there are various factors, such as nutrient availability, bacterial strains, and fermentation conditions, which influence the efficiency of PHB production. To further enhance the PHB production efficiency, novel technologies such as microwave and ultrasonic-assisted treatments are being explored for their ability to breakdown complex sugars in bio-waste into fermentable sugars. These interventions offer advantages over traditional methods, such as reduced energy consumption and minimal use of harmful chemicals and expensive enzymes. By utilizing agro bio-waste as feedstock for PHB production, not only can environmental concerns associated with traditional plastics be addressed, but the sustainability of the packaging industry can also be promoted. This review aims to provide an overview of microbial and technological interventions in PHB production from agro bio-waste, emphasizing their potential to promote sustainability and reduce plastic pollution.
