ChemSusChem, Journal Year: 2014, Volume and Issue: 7(6), P. 1579 - 1593

Published: May 8, 2014

Abstract Plastics are inexpensive, easy to mold, and lightweight. These many other advantages make them very promising candidates for commercial applications. In areas, they have substantially suppressed traditional materials. However, the problem of recycling still is a major challenge. There both technological economic issues that restrain progress in this field. Herein, state‐of‐art overview provided together with an outlook future by using popular polymers such as polyolefins, poly(vinyl chloride), polyurethane, poly(ethylene terephthalate) examples. Different types recycling, primary, secondary, tertiary, quaternary, biological discussed related issues, compatibilization cross‐linking. various projects European Union on research application these approaches; selected examples article.

Global Responses of Soil Carbon Dynamics to Microplastic Exposure: A Data Synthesis of Laboratory Studies

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: 58(13), P. 5821 - 5831

Published: Feb. 28, 2024

Microplastics (MPs) contamination presents a significant global environmental challenge, with its potential to influence soil carbon (C) dynamics being crucial aspect for understanding C changes and cycling. This meta-analysis synthesizes data from 110 peer-reviewed publications elucidate the directional, magnitude, driving effects of MPs exposure on globally. We evaluated impacts characteristics (including type, biodegradability, size, concentration), properties (initial pH organic [SOC]), experimental conditions (such as duration plant presence) various components. Key findings included promotion SOC, dissolved C, microbial biomass root following addition soils, while net photosynthetic rate was reduced. No were observed respiration shoot biomass. The study highlights that concentration, along other attributes, critically influences responses. Our results demonstrate both nature environment interact shape cycling, providing comprehensive insights guiding strategies mitigating impact MPs.

Impact of bioplastics on environment from its production to end-of-life

Process Safety and Environmental Protection, Journal Year: 2024, Volume and Issue: 188, P. 151 - 166

Published: May 24, 2024

The increasing demand for sustainable alternatives to conventional plastics has propelled the interest in bioplastics. While numerous studies have showcased their environmental advantages, particularly reducing global warming potential and fossil fuel usage, comprehensive reviews on holistic impacts of bioplastics throughout life cycle are scarce. This paper aims fill this gap by critically evaluating sustainability bioplastics, from production disposal. We find that impact is influenced feedstock choices, processing methods, disposal practices. Although intensive agriculture can cause acidification eutrophication as well incomplete biodegradation may lead formation bio-micro/nano-plastics, generally present a lower burden than traditional plastics, evidenced reduced carbon footprint enhanced biodegradability, which contributes decreased plastic waste. Importantly, positively affect soil dynamics, underscoring role promoting agricultural management advocate future Life Cycle Assessment develop inventory database enabling more thorough evaluation impacts. research provides critical insights policymakers viability

Microplastic contamination in marine mussels from the Atlantic coast of North Portugal and human risk of microplastic intake through mussel consumption

Environmental Pollution, Journal Year: 2024, Volume and Issue: 352, P. 124133 - 124133

Published: May 14, 2024

Microplastic (MP) pollution has become a global concern due to its potential impacts on the environment, ecosystem services and human health. The goals of present study were document MP contamination in wild specimens Mytilus galloprovincialis sampled along Atlantic coast North region Portugal continental (NW Portuguese coast), estimate risk intake (HRI) through consumption local mussels as seafood. Mussels collected at four sampling sites NW (40 per site), whole soft body each mussel was analysed for content. HRI estimates based mean items wet weight tissue (MP/g) habits. A total 132 recovered from mussels. had diverse sizes (98 2690 μm) colours. most common shapes fibres (39%) pellets (36%). Five polymers identified MP: polyethylene (50%), polystyrene (15%), poly(ethylene vinyl acetate) (14%), polyamide (12%) polypropylene (9%). From 160 mussels, 55% MP. standard error ranged 0.206 ± 0.067 0.709 0.095 MP/g. For consumers study, decreasing order is MOL > CAB CAR EST. Compared other areas varied habits, relatively low.

Beyond Microplastics: Implementation of a Two-Stage Removal Process for Microplastics and Chemical Oxygen Demand in Industrial Wastewater Streams

Water, Journal Year: 2024, Volume and Issue: 16(2), P. 268 - 268

Published: Jan. 12, 2024

Wastewater from plastic manufacturing or processing industries is often highly polluted with microplastics (MPs) and high levels of oxidizable organic matter, which results in a chemical oxygen demand (COD). When industrial wastewater enters streams, the microplastic load burden for municipal treatment plants (WWTPs), as they are not sufficiently removed. To prevent MP entering WWTPs, an upstream prevention method essential. This paper presents pilot-scale plant study removal COD that was tested on-site at manufacturer Germany. Eight test phases were performed over 3 months, each phase 1 m3 four treatments. Per phase, 12 samples analyzed 5 parameters: COD, total suspended solids (TSSs), particle count, pH, turbidity. The showed average decrease by 98.26 ± 2.15% measured TSSs 97.92 2.31% count. prevents emission 1.1 kg MP/m3 water estimated 2.7 t MP/year. reduced efficiently 94.3 8.9%. Besides this allows reuse agglomerates, resulting reduction CO2 footprint.
