Abstract:
Plastics, as a polymer material, have long been a source of environmental concern. This paper uses polystyrene plastics as the research object, and the relative contribution of each component of plastic additives to plastic degradation is screened using the molecular dynamics method. The factorial experimental design method is combined with molecular dynamics simulation to adjust the additive composition scheme, analyze the mechanism of interaction between the additive components, and select the plastic additive combination that is most readily absorbed and degraded by microorganisms.

Abstract:
Acrylonitrile–butadiene–styrene (ABS) plastic is a widely used engineering thermoplastic. ABS is also an interesting material for recycling. In the present study, two pieces of ABS plastic from waste computer equipment were reprocessed. A torque rheometer was used to simulate reprocessing. To identify the additives used in the recycled ABS plastics and understand the effect of reprocessing on the recycled plastics from several aspects, gas chromatography/mass spectrometry (GC/MS) was used to analyse the extracts from recycled ABS plastics before and after reprocessing.

Over the past 40 years, global plastic production has increased twenty-fold, prompting efforts to mitigate plastic waste. Recycling has emerged as the predominant strategy for sustainable plastic waste management.

Abstract:
The risk of plastic debris, and specifically micro(nano)plastic particles, to ecosystems remains to be fully characterized. One particular issue that warrants further characterization is the hazards associated with chemical additives within micro(nano)plastic as they are not chemically bound within the polymers and can be persistent and biologically active. Most plastics contain additives and are therefore potential vectors for the introduction of these chemicals into the environment as they leach from plastic, a process that can be accelerated through degradation and weathering processes.

Abstract:
The complexity of plastic polymers and even more so of additives has increased enormously in recent years. This makes the material recycling of plastic waste considerably more difficult, especially in the case of mixed plastic waste. Some additives have now been strictly regulated or even completely banned for good reasons (‘legacy additives’). Material or mechanical recycling generally uses old plastics that still contain these substances. Consequently, products that are manufactured using such recyclates are contaminated with these harmful substances. This poses a major challenge for sustain

ABSTRACTFor several decades additives have been incorporated into polymeric systems to improve desirable properties, and eliminate undesirable properties. When added to a polyethylene film, the additives migrate to the films’ surface and their concentration decreases; over time the additive’s effect desists. To solve this problem, efficient methods for extended performance are being sought. Extended additives’ performance is necessary to avoid frequent substitution of polyethylene films for different applications (e.g. greenhouses plastic coverings); as a result, reducing plastic waste and con

Xenoestrogens are compounds, foreign from the body, that can enter cells and interact with the estrogen receptors (ER) to produce an estrogenic response. Many additives used in plastics are compounds with estrogenic activity. Some of these additives are known to slowly leach from the plastics. When using plastic containers as lunchboxes for reheating or food storage, these additives can leach from the plastics and end up in the food.

Plastic debris is an emerging environmental issue, with >10 million tons of plastics debris per annum entering the sea. Exposure to marine conditions facilitates the exponential fragmentation of plastic to micro-sized particles (microplastics). Marine and coastal sediments are a sink for microplastic pollution. Consequently, the ingestion of microplastics by a range of benthic marine invertebrates, including polychaete worms, has been reported in situ.

There has been a growing trend in recent years for polymer product manufacturers to use natural polymer and additive masterbatches instead of premixed compounds. For both polymer converters and polymer manufacturers, masterbatching makes economic sense. For the converter, the advantage is in the ability to buy and store in bulk a small number of base polymers which may be modified according to the dictates of the order book. This prevents the need to maintain an inventory of a large number of special compounds. Masterbatch base is very often low molecular weight polyethylene or some suitable l

Abstract:
An analysis of the current state of the plastic waste problem is given. The rheology of molding solutions based on starch and sodium alginate containing plant additives in the form of aqueous extracts, essential oils and silver nanoparticles is described. The presence of thixotropic properties in compositions containing mint oil, in contrast to compositions containing citrus oils, has been established. It is shown that the films obtained from the studied molding compositions have antimicrobial and antioxidant activity.

Abstract:
Abstract In recent years, several research types have been carried out to produce environmentally-benign drilling fluid additives using locally sourced substances. Still, the formulation of a more effective and cheaper viscosifier for a better hole cleaning ability that lowers risk in lost circulation zones, especially at higher temperatures, remains a critical research subject. This study examines the use of Sweet Potato Peels Extract (PPE), a more readily available by-product, as a drilling fluid additive.

Abstract:
The circular economy encourages optimizing use of plastics, waste reduction, sustainable materials, and processing of plastic products. In this framework, the use of agricultural waste materials promotes waste reduction and eco-design in plastic product manufacturing. This study researched the preparation of an isotatic polypropylene (PP) matrix (MFI 50 grade) with spent coffee grounds (SCG) and various commercial additives. The biocomposites were analyzed to evaluate their mechanical properties and processability. PP and SCG composites were synthesized with 30% SCG content with maleic anhydri

Abstract:
The river source of plastic debris to the southern North Sea region appears to be increasing over the past several decades, with a strong seasonal control on riverine MP transport and discharge. The current cruise, AL586, links plastic pollution in the North Sea to seasonal studies in the Elbe and Thames rivers as part of the H2020 LABPLAS project, with the objective to understand the transport and fate of river-derived small micro- and nanoplastics (SMNPs) in the North Sea.

Cruise AL534/2 is part of a multi-disciplinary research initiative as part of the JPI Oceans project HOTMIC and sought to investigate the origin, transport and fate of plastic debris from estuaries to the oceanic garbage patches. The main focus of the cruise was on the horizontal transfer of plastic debris from major European rivers into shelf regions and on the processes that mediate this transport. Stations were originally chosen to target the outflows of major European rivers along the western Europe coast between Malaga (Spain) and Kiel (Germany), although some modifications were made in r

Abstract:
The rise in global temperatures, driven in part by significant transportation carbon emissions, necessitate sustainable solutions for infrastructure. Traditional asphalt binders and lime additives significantly contribute to carbon emissions, and conventional liquid amine-based antistrip agents, which are used to reduce moisture damage, lose efficacy over time. This study evaluates the performance of PG 64-16 Low Carbon binder, incorporating 10% post-consumer plastic and amine-impregnated zeolite (AIMZ) as a protective carrier for liquid amines.

Abstract:
Tire rubber waste (TRW) is a complex mixture of materials, such as rubbers, steel, textile fibers, carbon black, and other additives. Its polluting capacity is a severe environmental problem, especially in landfills and waste management processes. As a practical solution to mitigate TRW’s environmental impact, thermoplastic elastomers (TPE) commonly reuse the ground tire rubber (GTR). This work presents an in-situ devulcanization of ground tire rubber (DGTR) and re-vulcanization of devulcanized ground tire rubber using dicumyl peroxide (DCP) and waste ethylene-vinyl-acetate (wEVA).
