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

Microplastics in complex soil matrix: Recovery, identification and removal using micro nano techniques

Micro and Nano Engineering, Год журнала: 2024, Номер 22, С. 100237 - 100237

Опубликована: Янв. 4, 2024

Investigations on microplastic (MPs) particles in soils are extremely rare, and the published results often lack comparability due to different sampling, extracting, analytical approaches used. The current techniques for examining tiny MPs soil samples not particularly effective, but minor adjustments method combinations should be explored. complexity of matrix presents challenges developing a standardized approach characterizing removing them effectively, heterogeneity composition, variability their size/shape, interactions with particles, background contamination, methodological variations. This review focuses evaluating various methods extraction, purification, identification, measurement removal complex systems. A recommended methodology extracting from is proposed, aiming provide systematic recovery identification. Furthermore, article discusses sampling plans, drying sieving techniques, density separation methods, special emphasis photocatalytic removal. also addresses encountered such analyses suggests possible solutions, followed by future prospects. Additionally, importance environment highlighted, underscoring need effective methodologies tackling this pressing issue.

Advancements and Regulatory Situation in Microplastics Removal from Wastewater and Drinking Water: A Comprehensive Review

Microplastics, Год журнала: 2024, Номер 3(1), С. 98 - 123

Опубликована: Фев. 8, 2024

In recent years, the ubiquitous occurrence of plastic debris has become a significant environmental concern, posing considerable harm to our ecosystems. Microplastics (MPs) (1 μm–5 mm) and nanoplastics (NPs) (<1 μm) are noticeable in diverse forms, spreading throughout environment. Notably, wastewater treatment plants (WWTPs) emerge as major contributors generation MP NP. Within these plants, water influx from domestic commercial sources carries load MPs derived items like fiber clothing, personal care products, toothpaste. Lacking dedicated removal mechanisms, persist through process, ultimately entering natural bodies soil The novelty this review lies its detailed examination contemporary methodologies for sampling, detecting, eliminating specifically WWTPs. By critically assessing efficacy current techniques at various stages, offers targeted insights into practical aspects management facilities. As study micro/nano plastics is still early article aims contribute by offering comprehensive methods utilized both WWTPs drinking (DWTPs). Furthermore, provides overview existing rules, regulations, policies concerning United States. This inclusion not only broadens scope but also establishes it valuable reference understanding regulatory framework related MPs. uniquely combines focused evaluation WWTPs/DWTPs, an exploration methods, framework, making different contribution article. Through review, we aim enhance awareness multi-layered challenges posed MPs, that can inform future research directions policy initiatives.

Advanced nanobubble flotation for enhanced removal of sub-10 µm microplastics from wastewater

Nature Communications, Год журнала: 2024, Номер 15(1)

Опубликована: Окт. 21, 2024

Sub-10 µm microplastics (MPs) in aquatic environments pose significant ecological and health risks due to their mobility potential carry harmful microcontaminants. Our effluent analysis from a Hong Kong Sewage Treatment Works shows that traditional treatment often fails effectively remove these MPs. These small-sized MPs are commonly neglected challenges accurate quantification, analysis, removal. This study introduces nanobubble-assisted flotation process enhances the removal efficiency of both regular irregular wastewater. The proposed outperforms by fostering more effective interaction between bubbles MPs, increasing rates 1 10 up 12% providing total boost 17% for various particle sizes. Improvements attributed enhanced collision adhesion probabilities, hydrophobic interactions, as well better floc flotation. Supported empirical evidence, mathematical models, Molecular Dynamics simulations, this research elucidates nanoscale mechanisms at play. findings confirm technique an innovative practical approach removing sub-10 water processes. microplastic severe environmental risks. Here, authors introduce advanced nanobubble assisted removal, promising solution treatment.
