Opportunities and Challenges in the Application of Bioplastics: Perspectives from Formulation, Processing, and Performance

Polymers, Journal Year: 2024, Volume and Issue: 16(18), P. 2561 - 2561

Published: Sept. 10, 2024

Tremendously negative effects have been generated in recent decades by the continuously increasing production of conventional plastics and inadequate management their waste products. This demands materials within a circular economy, easy to recycle biodegrade, minimizing environmental impact cost competitiveness. Bioplastics represent sustainable alternative this scenario. However, replacement must be addressed considering several aspects along lifecycle, from bioplastic processing final application product. In review, using different additives, biomass sources, techniques on mechanical thermal behavior, as well biodegradability, bioplastics is discussed. The importance bioplasticizers highlighted, besides studying role surfactants, compatibilizers, cross-linkers, coupling agents, chain extenders. Cellulose, lignin, starch, chitosan, composites are analyzed part non-synthetic considered. Throughout study, emphasis use well-established manufacturing processes, such extrusion, injection, compression, or blow molding, since these ones that satisfy quality, productivity, requirements for large-scale industrial production. Particular attention also given fused deposition modeling, additive technique nowadays not only used making prototypes, but it being integrated into development parts wide variety biomedical applications. Finally, recyclability commercial discussed, some future perspectives challenges bio-based with conclusion technological innovations, economic incentives, policy changes could coupled individually driven solutions mitigate impacts associated plastics.

To promote the chemical recycling of polyethylene terephthalate (PET), its valorization by hydrocracking was investigated. ease implementation at large-scale this route, PET coprocessed with vacuum gasoil (VGO), which is a benchmark feed industrial unit (10 and 90 wt %, respectively) hydrocracked using PtPd/HY catalyst. Furthermore, suitability PETs different natures origins to produce fuel-assimilable streams assessed. Specifically, one virgin, commercial, mechanically recycled were used, analyzing differences in conversion, yields product fractions (dry gas, liquefied petroleum gases, naphtha, light cycle oil), composition naphtha oil fractions, given their possible interest being used formulation automotive fuels. The reaction runs performed batch reactor under following conditions: 80 bar, 420 °C, 120 min, catalyst/feed mass ratio 10 gcatalyst gfeed–1. modified degraded plastics more easily converted into liquid hydrocarbons within LCO contents isoparaffins between 45 50 %.

Nano Cobalt-Loaded Porous Carbon Derived from Waste Plastic for Efficient Persulfate Activation and Tetracycline Degradation

Nanomaterials, Journal Year: 2025, Volume and Issue: 15(5), P. 371 - 371

Published: Feb. 27, 2025

The excessive utilization and emission of waste plastics have caused serious damage to the environment, it is great significance explore high-value methods for these plastics. To address this challenge, functional nano cobalt-loaded porous carbon materials (CoPC) with excellent antibiotic wastewater removal properties were prepared by one-step pyrolysis using PET as a source, process described in paper. Characterization revealed that obtained CoPC-2 catalysts had high degree defects, large specific surface area (343.41 m2/g), an abundant pore structure. Degradation results displayed removed 87.93% 20 mg/L tetracycline reaction rate constant 0.0668 min-1. Moreover, exhibited degradation performance over wide range pH levels (4-10) coexistence multiple inorganic anions. Electron paramagnetic resonance radical quenching experiments radicals (·OH, SO4·-) non-radicals (1O2) pathway participated degradation, non-radical being dominant. This study not only offers promising prospects resource plastics, but also provides novel approaches design nanomaterials treatment.
