ABSTRACT:
With increasing population we face the problem of plastic pollution, and its side effects on the environment have increased the search for sustainable alternatives, leading to the discovery of bioplastics as a viable, sustainable and reliable solution. Bioplastics, particularly polylactic acid (PLA), offer a sustainable and biodegradable alternative to conventional plastics. PLA production has the potential to reduce and repurpose agricultural waste, like starch- and cellulose-rich residues, into a valuable resource, thus contributing to waste management and promoting environmental sustainability. However, challenges such as low lactic acid yield, feedstock variability, and the scalability of production processes makes large scale production of PLA difficult. This review focuses on different techniques used to optimize PLA production by investigating the efficiency of various agricultural residues as feedstocks, incubation parameters, and microbial consortia. This review explores refining fermentation conditions, including pH, temperature, and incubation time, to maximize lactic acid yield. Synergistic microbial consortia, combining Lactobacillus species with complementary fungal strains, are evaluated to enhance fermentation efficiency and yield. The study evaluates the impact of feedstock type (cellulose-based, starch-based, and oil- based), incubation time, and microbial combinations on bioplastic yield. Starch-based feedstocks emerge as efficient substrates due to their simpler structures, while cellulose-based materials require pre-treatment for effective hydrolysis. Lactobacillus, isolated from common sources like curd, is highlighted for its increased fermentation potential. Additionally, challenges in cellulose hydrolysis, the role of microbial consortia, and the feasibility of integrating sustainable practices are discussed. This review aims to provide insights into the critical factors affecting bioplastic production and highlight future directions for achieving efficient and sustainable processes using agricultural waste.
