The great utility that plastics generate for society has generated a large amount of waste, producing tons garbage from this material damages the ecosystem, human health, and farmland. Likewise, issue absence electricity in low-income areas is critical society. This research proposes novel solution to simultaneously solve these two problems, which, through single-chamber microbial fuel cells, introduce plastic waste fungus Paecilomyces. cells (MFCs) showed maximum electric current 0.547 ± 0.185 mA with peak voltage 0.575 0.106 V on day 36; day, MFCs operated pH 6.524 0.360 electrical conductivity 264.847 6.395 mS/cm. These results demonstrate potential system addressing scarcity areas. chemical oxygen demand was also reduced by 85.47%, indicating system’s ability degrade waste. power density calculated 36 0.0624 0.0053 mW/cm2 at 0.0052 mA/cm2 an internal resistance 55.254 7.583 Ω. reducing action demonstrated FTIR transmittance spectrum because characteristic peaks (3378, 2854–2911, 1642, 1472, 720 cm−1) suffered reductions final state, micrographs surfaces lifting layers formation irregular structures decrease thickness sample 139.66 4.19 µm.

Recent advances in chemical recycling of polyoxymethylene waste

Energy & Environment, Год журнала: 2024, Номер unknown

Опубликована: Окт. 10, 2024

The demand for engineering plastics, such as polyoxymethylene (POM), used in the electronics and automotive industries is increasing rapidly. It becoming increasingly important to reduce adverse effects of waste plastics on environment ecosystem achieve goals circular economy. Pyrolysis, gasification, hydrothermal conversion, solvolysis, electrochemical depolymerization have been widely studied chemical methods manage plastic waste. Chemical recycling a representative effective approach recover monomers or syngas from This paper reviews properties POM waste, various reaction mechanisms options with major studies. In addition, economic feasibility discussed. Finally, opportunities future challenges regarding are suggested.
