Bioplastic: an eco‐friendly alternative to non‐biodegradable plastic

Polymer International, Journal Year: 2023, Volume and Issue: 72(11), P. 984 - 996

Published: June 15, 2023

Abstract The accumulation of non‐biodegradable plastic waste in land and aquatic environments is expanding every day. According to data collected from various scientific reports, about 100–250 megatonnes arrives the oceans annually. Central Control Board India (2019–2020), produces 3.5 million metric tonnes annually, while only 5–10% produced recycled. non‐recycled dumped into environment either goes landfills or directly sea, which disrupts marine life ocean. We are highly dependent on at household industrial scales. Removal lowering use hazardous plastics main challenges. Researchers industrialists have come up with many ideas lower generation found that reusability easier than degradability, bioplastics ultimate solution tackle problem. Hence, developing eco‐friendly alternative without compromising physicochemical mechanical properties need hour. An conventional petrochemical bioplastics, environmentally safe, reduce our dependency fossil reserves. Therefore, this review focuses as an efficient plastics. Among renewable sustainable feedstocks available, vegetable oils most suitable resource for bioplastic production because their renewability economical nature. study concluded polyurethane‐based polymers inherently more other © 2023 Society Industrial Chemistry.

Degradation of thermoplastic cellulose acetate-based bioplastics by full-scale experimentation of industrial anaerobic digestion and composting

Chemical Engineering Journal, Journal Year: 2023, Volume and Issue: 462, P. 142301 - 142301

Published: March 9, 2023

The ability of full-scale industrial plants to degrade bioplastics waste must be verified exclude any negative effects on the quality process outputs. This study aims assess degradation two thermoplastic cellulose acetate-based bioplastics, in pure and composite forms both Anaerobic Digestion (AD) Composting (C) conditions. main occurred during AD, where a disintegration about 36% 50% was achieved from acetate, respectively. C did not exceed 20% for samples. combined resulted slightly higher (58–40%) than that obtained revealing how alteration samples an anaerobic environment. Despite this macroscopic degradation, showed only minor superficial as highlighted SEM analysis. FT-IR spectroscopy, TGA andDSC analyses biodegradation mechanism involved mainly plasticizer loss deacetylation matrix, with partial backbone However, were favored AD + processes presence filler These results demonstrated scale can differ significantly those laboratory scale, especially acetate. Furthermore, current optimized treatment bioplastics. Hence, works could help facilities managers emerging materials such more sustainable way.

Published: Nov. 22, 2023

In recent years, a great deal of attention has been focused on the environmental impact plastics, including carbon emissions related to which promoted application biodegradable plastics. Countries worldwide have shown high interest in replacing traditional plastics with However, no systematic comparison conducted versus plastic products. This study evaluates and products (BPPs) over four stages briefly discusses economic perspectives. Four scenarios—namely, method, chemical recycling, industrial composting, anaerobic digestion—are considered for disposal waste product (WBBPs). The analysis takes China as case study. results show that 1000 (plastic bags, lunch boxes, cups, etc.) were 52.09–150.36 equivalent per kg (kg CO2eq), stage production contributing 50.71%–50.77%. comparison, similar BPPs topped out at 21.06–56.86 CO2eq, approximately 13.53%–62.19% lower than difference was mainly disposal, showed significant reduction potential raw material acquisition stage. Waste plays an important role impact, composting digestion are be preferable methods WBBPs. cost is challenge their widespread use. reference significance sustainable development industry.
