Sustainable bioconversion of synthetic plastic wastes to polyhydroxyalkanoate (PHA) bioplastics: recent advances and challenges

Millions of tons chemical plastics are accumulated annually worldwide in terrestrial and marine environments due to inadequate recycling plants facilities low circular use. Their continuous accumulation contamination soil water pose a severe threat the environment human, animal plant health. There is therefore an urgent need develop effective eco-environmental strategies overcome significant environmental impacts traditional plastic waste management practises (incineration, landfilling, recycling). In recent years, reports on microbial strains equipped with potential degrading materials, which can further be converted into usable products such as PHA bioplastics have sprung up, these offer possibility enzymatic technologies for treatment then progressing circularity. this chapter, overview reported degradations petroleum-based synthetic plastics, specifically polyethylene, polystyrene, polypropylene, polyvinyl chloride, polyurethane polyethylene terephthalate, detailed. Furthermore, harvesting depolymerization produce new materials high added industrial value considered innovative solution, helping increase rate creating economy opportunities. Finally, challenge ending pollution still difficult, but sustainable, renewable, bio-based completely biodegradable, will hold enormous promise replacing made from petrochemicals.
