Advancements in Biodegradable Active Films for Food Packaging: Effects of Nano/Microcapsule Incorporation

Foods, Journal Year: 2022, Volume and Issue: 11(5), P. 760 - 760

Published: March 6, 2022

Food packaging plays a fundamental role in the modern food industry as main process to preserve quality of products from manufacture consumption. New technologies are being developed that formulated with natural compounds by substituting synthetic/chemical antimicrobial and antioxidant agents fulfill consumers' expectations for healthy food. The strategy incorporating into structures is recent promising technology reach this goal. Concepts such "biodegradable packaging", "active "bioactive packaging" currently guide research development packaging. However, use faces some challenges, including weak stability sensitivity processing storage conditions. nano/microencapsulation these bioactive enhances their controls release. In addition, biodegradable materials gaining great attention face ever-growing environmental concerns about plastic pollution. They sustainable, environmentally friendly, cost-effective alternative conventional materials. Ultimately, combined formulation nano/microencapsulated molecules, incorporated system, offers many benefits preventing spoilage, extending shelf life food, reducing waste, preserving freshness objective review illustrate latest advances principal used active systems, well most common food-packaging

FloW: A Dataset and Benchmark for Floating Waste Detection in Inland Waters

2021 IEEE/CVF International Conference on Computer Vision (ICCV), Journal Year: 2021, Volume and Issue: unknown

Published: Oct. 1, 2021

Marine debris is severely threatening the marine lives and causing sustained pollution to whole ecosystem. To prevent wastes from getting into ocean, it helpful clean up floating in inland waters using autonomous cleaning devices like unmanned surface vehicles. The efficiency relies on a high-accurate robust object detection system. However, small size of target, strong light reflection over water surface, other objects bank-side all bring challenges vision-based promote practical application for cleaning, we present FloW ^† , first dataset waste areas. consists an image sub-dataset FloW-Img multimodal FloW-RI which contains synchronized millimeter wave radar data images. Accurate annotations images are provided, supporting strategies based image, data, fusion two sensors. We perform several baseline experiments our dataset, including radar-based methods. results show that, accuracy relatively low still remains challenging task.

Hydrology as a Driver of Floating River Plastic Transport

Earth s Future, Journal Year: 2022, Volume and Issue: 10(8)

Published: July 12, 2022

Abstract Plastic pollution in aquatic ecosystems is a growing threat to ecosystem health and human livelihood. Recent studies show that the majority of environmental plastics accumulate within river systems for years, decades potentially even longer. Long‐term system‐scale observations are key improve understanding transport retention dynamics, identify sources sinks, assess potential risks. The goal this study was quantify explain variation floating plastic Rhine‐Meuse delta, using novel 1‐year observational data set. We found strong positive correlations between discharge. During peak discharge events, up six times higher than under normal conditions. varied factor four along Rhine Meuse rivers, which hypothesized be related complex network, locations urban areas, tidal dynamics. Altogether, our findings demonstrate important role hydrology as driving force Our emphasizes need exploring other factors may spatiotemporal transport. world's most polluted rivers connected ocean through deltas. Providing reliable data‐driven insights dynamics optimize prevention reduction strategies. With paper we aim contribute both advancing fundamental establishment long‐term harmonized collection at basin scale.

Measuring riverine macroplastic: Methods, harmonisation, and quality control

Water Research, Journal Year: 2023, Volume and Issue: 235, P. 119902 - 119902

Published: March 20, 2023

River systems are a key environmental recipient of macroplastic pollution. Understanding the sources to rivers and mechanisms controlling fate transport is essential identify tailor measures that can effectively reduce global plastic Several guidelines exist for monitoring in rivers; yet, no single method has emerged representing standard approach. This reflects substantial variability river globally need adapt methods local context goals. Here we present critical review used measure flows rivers, with specific focus on opportunities testing, harmonisation, quality assurance control (QA/QC). studies have already revealed important findings; however, there significant disparity reporting methodologies data.

Cleaning Up without Messing Up: Maximizing the Benefits of Plastic Clean-Up Technologies through New Regulatory Approaches

Environmental Science & Technology, Journal Year: 2023, Volume and Issue: 57(36), P. 13304 - 13312

Published: Aug. 28, 2023

As the global plastics crisis grows, numerous technologies have been invented and implemented to recover plastic pollution from environment. Although laudable, unregulated clean-up may be inefficient unintended negative consequences on ecosystems, for example, through bycatch or removal of organic matter important ecosystem functions. Despite these concerns, can play an role in reducing litter United Nations Environment Assembly is moving toward international, legally binding treaty address by 2024, implementation should regulated secure their net benefits avoid damages. Regulation require environmental impact assessments life cycle analysis conducted predeployment a case-by-case basis determine effectiveness environmentally sound management. During operations catch-efficiency nonlitter items, as well waste management recovered litter, documented. Data collection monitoring, research, outreach mitigate recommended added value technologies.

Tackling Marine Microplastics Pollution: an Overview of Existing Solutions

Water Air & Soil Pollution, Journal Year: 2022, Volume and Issue: 233(7)

Published: July 1, 2022

Abstract Microplastics pollution is one of the main environmental challenges our time, even though microplastics were observed for first time almost 50 years ago. Microplastics—little plastic fragments smaller than 5 mm in size—are released from bigger objects during their use, maintenance, or disposal. As release uncontrolled and mostly uncontrollable, end up environment are easily transported across world, polluting nearly every ecosystem, especially aquatic ones. Hence, represent a huge menace many living species: they ingested unintentionally by animals transferred along food chain to human beings, threatening health. It therefore vital take action against technologies have been designed recent with this purpose mind. This paper provides an overview solutions developed thus far reduce further microplastic emissions collect those already released.
