Abstract

Organic waste valorization offers a promising pathway for the creation of value-added products like bioplastics, while simultaneously mitigating the financial burdens associated with waste management. This study thoroughly examines the prospect of the production of bio-plastics from organic waste and thereby reducing the waste management burden in the context of Bangladesh. Urban areas of Bangladesh generate around 23,688 tons/day of municipal solid waste (MSW) of which 68.3-81.1% are organic and 75% of that organic fraction is food waste. By 2025, the urban population is expected to reach 78.44 million, generating 47,000 tons/day of garbage with 0.6 kg/day production rate. Studies have surfaced that the organic fraction of Municipal Solid Waste (OF-MSW) shows potential for producing polyhydroxyalkanoates (PHAs), with Enterobacter aerogenes bacteria producing 40g of PHAs from 1kg of O-MSW, alongside other byproducts, which equates to about 8236.9 kJ of energy. At a 40% efficiency rate, 18,800 metric tons of PHAs can be produced daily which results in an annual production of 6,862,000 metric tons of PHAs, which is approximately twice the anticipated plastic demand by 2050, i.e. 3,657,560 metric tons. This reduces waste and lessens dependence on non-renewable petroleum. Though bioplastic costs (2.4 - 5.5 US$/kg) are higher than petroleum-based plastics (0.13-1.2 US$/kg), large-scale production and technology advancements may lower costs by 15-19%. The projected expense for fulfilling Bangladesh’s plastic demand by 2050 is estimated at US$4,750.43 million for bioplastic. Unlike conventional plastics, bioplastics cause 20-50% less environmental harm, offering a more eco-friendly alternative.
