Current Concerns about Microplastics and Nanoplastics: A Brief Overview

Polymers, Journal Year: 2024, Volume and Issue: 16(11), P. 1525 - 1525

Published: May 29, 2024

The widespread and increasing use of plastic-based goods in the present-day world has been raising many concerns about formation microplastics, their release, impacts on environment and, ultimately, living organisms. These are even greater regarding nanoplastics, i.e., nanosized which may have impacts. In this brief review, although without any claim or intention to exhaustively cover all aspects such a complex many-sided issue, very topical problem more worrisome from polymer-based products was considered. approach is focused terse, straightforward, easily accessible analysis oriented main technological engineering sources microplastics nanoplastics released into environment, nature, some consequences arising different polymers involved, form (i.e., processes, with particular attention towards unintentional release), mechanisms, possible mitigation pathways.

Degradation rates and ageing effects of UV on tyre and road wear particles

Chemosphere, Journal Year: 2025, Volume and Issue: 372, P. 144121 - 144121

Published: Jan. 21, 2025

Tyre and road wear particles (TRWPs) are estimated to be the largest source of microplastics in environment due intrinsic use tyres our society this will continue grow. Understanding their degradation mechanisms subsequent accumulation over time is important gain insights into fate impact these environment. Accelerated UV-ageing was performed on cryomilled tyre tread TRWPs from a simulator investigate abiotic rubber. Degradation followed with thermogravimetric analysis (TGA) that led an average rate 0.025 day-1 when corrected for acceleration factor. Static light scattering (SLS) showed during degradation, particle size reduced by 0.03 μm smaller <10 were formed. Further characterisation scanning electron microscopy (SEM) energy dispersive x-ray spectroscopy (EDX) confirmed findings sulphur content through suggesting crosslinking breakage may mechanism degradation. Analysis gas chromatography mass spectrometry (GC-MS) substantial decrease chemical additives UV-induced oxidation breakdown. Finally, measurements field TRWP sizes times studied, confirming experimentally determined mechanisms.

Measures to Reduce the Discharge of tire Wear into the Environment

Microplastics, Journal Year: 2024, Volume and Issue: 3(2), P. 305 - 321

Published: June 4, 2024

The environmental impact of tire wear emissions has become increasingly apparent, and efforts to reduce their on the environment are rise. To minimise generation wear, it is essential consider influencing factors. However, as cannot be entirely prevented, measures immissions also necessary. This paper summarises possible derived from literature, stakeholder workshops, authors’ own conclusions, taking into account different perspectives: tire, vehicle, road, sustainable mobility treatment. presentation entry paths hotspots can used prioritise reduction measures. Measures should implemented at a political level, technical solutions applied, awareness raised among general public. It evident that reducing complex task requires transdisciplinary approach.

Carbon Recycling of High Value Bioplastics: A Route to a Zero-Waste Future

Polymers, Journal Year: 2024, Volume and Issue: 16(12), P. 1621 - 1621

Published: June 7, 2024

Today, 98% of all plastics are fossil-based and non-biodegradable, globally, only 9% recycled. Microplastic nanoplastic pollution is just beginning to be understood. As the global demand for sustainable alternatives conventional continues rise, biobased biodegradable have emerged as a promising solution. This review article delves into pivotal concept carbon recycling pathway towards achieving zero-waste future through production utilization high-value bioplastics. The comprehensively explores current state bioplastics (biobased and/or materials), emphasizing importance carbon-neutral circular approaches in their lifecycle. chiefly used low-value applications, such packaging single-use items. sheds light on value-added like longer-lasting components products, demanding properties, which increasingly being deployed. Based waste hierarchy paradigm—reduce, reuse, recycle—different use cases end-of-life scenarios materials will described, including technological options recycling, from mechanical chemical methods. A special emphasis common bioplastics—TPS, PLA, PHAs—as well discussion composites, provided. While it acknowledged that (waste) crisis stems largely mismanagement, needs stated radical solution must come core material side, intrinsic properties polymers formulations. manner cascaded bioplastics, labeling, legislation, technologies, consumer awareness can contribute topics this article.

Examining the effectiveness of municipal street sweeping in removing road-deposited particles and metal(loid)s of respiratory health concern

Environment International, Journal Year: 2024, Volume and Issue: 187, P. 108697 - 108697

Published: April 24, 2024

Road dust is a demonstrated source of urban air pollution. Given this, the implementation street sweeping strategies that effectively limit road accumulation and resuspension should be public health priority. Research examining effectiveness for removal in support good quality has been limited to date. To address study aimed assess use regenerative-air sweeper efficiently remove particles metal(loid)s size fractions relevant respiratory exposure Toronto, Canada. As part mass amounts, particle distribution elemental concentrations bulk before after at five arterial sites were characterized. Sweeping reduced total amount thoracic-sized (<10 µm) by 76 % on average. A shift remaining toward finer was observed post samples, together with an enrichment many such as Co, Ti S. Overall, amounts concern like Cu Zn greatly sweeping. Traffic volume surface predictors loadings concentrations. also found impact efficiencies, larger per unit area collected where surfaces distressed. This demonstrates using advanced technology can highly effective removal, highlighting its potential improvement efforts. The importance tailoring service levels technologies locally traffic patterns emphasized. Continued efforts mitigate non-exhaust emissions pose risk their essential.
