Abstract:
... Biodegradable plastics (BPs) have been used to replace conventional plastics owing to their environmental harmless and ease of degradation. However, the aging processes of BPs in different environments remain unclear. In this study, we used poly (lactic acid)/poly (butylene adipate-co-terephthalate) (PLA/PBAT) films as model BPs and investigated the 30-d aging behavior of PLA/PBAT films under four ...

Abstract:
... Ocean acidification and plastic pollution are considered as potential planetary boundary threats for which crossing certain thresholds could be very harmful for the world's societies and ecosystems well-being. Surface oceans have acidified around 0.1 units since the Industrial Revolution, and the amount of plastic reaching the ocean in 2018 was quantified to 13 million metric tonnes. Currently, bo ...
... The pyrolysis of waste plastics alleviates the ecological pollution of plastics. In addition to the high-quality oil component of the target product, there are solid residues from incomplete pyrolysis. These residues have a great potential as fuels due to their high carbon content and partial oil content. Currently, few studies have focused on the rational utilisation of waste plastics pyrolysis b ...

Different types of textiles have properties which are suitable for the construction of elements able to condition sound in rooms. The use of these elements can foster acoustic comfort in all kind of rooms, both public and private. This work is a review of the possibilities and trends of textile materials in the field of ...
plastics, etc ; bananas; chlorpyrifos; hydrolysis; photolysis; Colombia; Show all 6 Subjects
Abstract:
... In Colombia, plastic bags containing the pesticide chlorpyrifos protect the growing bunches of bananas and plantains from insects. When the bananas are harvested, the plastic bags are removed. This plastic, which may contain chlorpyrifos residues, is sometimes reused or recycled for other uses such as toy manufacturing. This is prohibited by environmental authorities in Colombia. The paper reports ...

Abstract:
... In this study, the factors influencing the carbon intensity (tCO₂/t crude steel) transition in the Japanese iron and steel industry from FY2000 to FY2019 were empirically evaluated. The results revealed that the upper processes (i.e., the hot-metal ratio, waste plastic, and waste tires), steel product mix, capacity factor, and linear time trend variable explain the actual carbon intensity trajecto ...
... The Aegean Sea is one of the most contaminated by marine litter (ML) in the World. In this study, the Turkish Aegean Region was evaluated in light of the sources, abundance and composition of ML along Çakalburnu Lagoon coast. Macroscopic ML with > 3 cm was collected and separated into composition and sources categories. ML abundance was calculated by its density in items/m² (Mean ± SD). Beach clea ...

Abstract:
... Many studies focus on the transport of plastic from rivers to oceans while little attention was paid to the plastic transport in the upper reaches of rivers. Transport process of plastic from upstream to downstream in the whole river basin scale is still poorly understood. In this work, five sections in the upper reaches of the Yangtze River were investigated to characterize the features of plasti ...

Abstract:
... The environmental concern of end-of-life vehicles and stringent environmental regulation like the resource conservation and recovery act of the USA, and registration, evaluation, authorization, and restriction of chemicals act of EU and Korea mandates the recycling of the ELV. The EU-Directive 2000/53/EC on end-of-life vehicles was enacted in 2000, imposed a target to recycle for reuse and recover ...

Abstract:
... Pyrolysis-catalysis is a promising method to realize the recycling of waste plastic. Thereinto, metal-support interaction (MSI) has a crucial impact on the properties and performances of catalysts. Different active metal components (Ni or/and Fe) and pre-reduction process were introduced to adjust the metal-support interaction in this work. The results showed that moderate MSI was obtained from Ni ...

Abstract:
... Plastic production and worldwide use of plastic materials have continued to rise due to their convenience and excellent marketing advantages. This is generating an environmental crisis and global scale pollution which is one of the greatest threats to our planet. One of the best responses could be accomplished by improving recycling and waste management strategies. In this paper we conducted Raman ...

Abstract:
... Multiphase polypropylene is an important engineering plastic. Stickiness concerns in multiphase polypropylene particles with a high rubber content are well known, and they are not favorable to industrial production stability. However, there has been a scarcity of green and effective surface stickiness reduction techniques. In this work, a Damp mode was employed to construct multiple concentration ...

Abstract:
... Raw natural clinoptilolite from the Slovak deposit in Nižný Hrabovec and clinoptilolite treated with solution of hydrochloric acid (0.1 M) were used to promote cracking of polypropylene (PP), as a representative of the second most common plastic in municipal waste, into valuable gaseous and liquid hydrocarbons. The influence of catalyst was studied using two-stage cracking apparatus. The process c ...

Abstract:
... Plastic pollution has now been found within multiple ecosystems across the globe. Characterisation of microbial assemblages associated with marine plastic, or the so-called ‘plastisphere’, has focused predominantly on plastic in the epipelagic zone. Whether this community includes taxa that are consistently enriched on plastic compared to surrounding non plastic surfaces is unresolved, as are the ...

Abstract:
... We report a method to turn a 3D-printed plastic piece into a five-electrodes chip for multiple analytes detection. A chip containing Pd, Ni, and Ru working electrodes is used to sense hydroquinone, acetaminophen, salicylic acid, and hydroxychloroquine at once. The analysis is sequentially achieved simply by changing the proper electrode connection, without changing mobile parts, neither adding rea ...

... Pollution by polymeric materials - in particular plastics - has a negative effect on the health of our planet. Approximately 4.9 billion tons of plastic are estimated to have been improperly disposed of, with the environment as their final destination. This scenario comes from a linear economic system, extraction-production-consumption and finally disposal. The alarming panorama has created the ne ...
