Sewage Derived Microplastic and Anthropogenic Fibre Retention by Integrated Constructed Wetlands

High loads of microplastics and anthropogenic fibres can be discharged from wastewater treatment plants (WWTPs) into surface water bodies. Integrated Constructed Wetlands (ICWs) are potentially well suited to provide a cost-effective mitigation solution at small WWTPs where conventional treatment is prohibitively expensive. This study aimed to assess the microplastic and anthropogenic fibre retention efficiency of two ICWs (Northrepps and Ingoldisthorpe) in Norfolk (UK) over a 12-month period (2022–2023). Analysing a total of 54 water and 23 sediment samples, the findings revealed that Northrepps ICW received on average 349,920 (± 763,776) anthropogenic fibres day−1, with a retention rate of 99.3%. No seasonal variation was observed in retention efficiency. Ingoldisthorpe ICW intermittently received anthropogenic fibres in low concentrations, with an average of 9504 (± 19,872) day−1 and a retention rate of 100%. Microplastics and anthropogenic fibres were prevalent in sediment samples of the first cell of Northrepps ICW, averaging 10,090 items kg−1 dry sediment, while none were found at concentrations above the limit of detection in the second or third cell. Of the 369 fibres analysed by ATR-FTIR, 55% were plastic (dominated by polyester). Of the 140 suspected microplastic fragments analysed by ATR-FTIR, 73% were confidently identified as plastic (mostly polystyrene, polyethylene, or polypropylene). This study demonstrates how ICWs can effectively retain sewage effluent derived microplastics and anthropogenic fibres. However, the accumulation of plastic waste in ICWs may complicate long term management and their cost-effectiveness.

This paper provides an overview of existing pyrolysis techniques for plastic waste and discusses the parameters that influence product yield and selectivity. It explores the impact of different catalysts on the pyrolysis process and offers a comparative assessment with the conventional pyrolysis. By recovering plastic waste through pyrolysis, the dependence on non-renewable fossil fuels can be reduced, bolstering energy sustainability while mitigating plastic waste’s environmental repercussions. This paper also discusses the deactivation and regeneration mechanisms of the catalysts, as well as strategies to optimize liquid oil production from plastic waste, highlighting the potential for utilizing pyrolysis-derived liquid oil as a more sustainable energy source. Lastly, the paper includes a discussion on the future outlook of the pyrolysis industry. This review would provide recommendations for future research directions, enabling researchers and stakeholders to identify key areas of interest and develop new projects accordingly.

Photochemical Aerobic Upcycling of Polystyrene Plastics.

Although the introduction of plastics has improved humanity's everyday life, the fast accumulation of plastic waste, including microplastics and nanoplastics, have created numerous problems with recent studies highlighting their involvement in various aspects of our lives. Upcycling of plastics, the conversion of plastic waste to high-added value chemicals, is a way to combat plastic waste that is receiving increased attention. Herein, we describe a novel aerobic photochemical process for the upcycling of real-life polystyrene-based plastics into benzoic acid. A new process employing a thioxanthone-derivative, in combination with N-bromosuccinimide, under ambient air and 390 nm irradiation is capable of upcycling real-life polystyrene-derived products in benzoic acid in yields varying from 24-54%.

Selective Photoreforming of Waste Plastics into Diesel Olefins via Single Reactive Oxygen Species

The accumulation of plastic waste poses a pressing environmental challenge. Catalytic conversion stands out as an ideal approach for plastics upcycling, particularly through solar‐driven plastics photoreforming. However, due to the common effects of multiple reactive oxygen species (ROS), selectively generating high‐value chemicals becomes challenging. In this study, we developed a universal strategy to achieve >85% selective production of diesel olefins (C15‐C28) from polyolefin waste plastics via single ROS. Using tetrakis (4‐carboxyphenyl) porphyrin supramolecular (TCPP) with different central metals as an example to regulate single ROS generation, results show Ni‐TCPP facilitates triplet exciton production, yielding 1O2, while Zn‐TCPP generates •O2− due to its strong built‐in electric field (IEF). 1O2 directly dechlorinates polyvinyl chloride (PVC) due to the electro‐negativity of chlorine atoms and the low dissociation energy of C‐Cl bonds, while •O2− promotes direct dehydrogenation of polyethylene (PE) due to the electro‐positivity of hydrogen atoms and the high dissociation energy of C‐H bonds. This method is universally applicable to various single ROS systems. Installation experiments further affirm the application potential, achieving the highest diesel olefin production of 76.1 μmol·h‐1. Such a universally adaptive approach holds promise for addressing the global plastic pollution problem.

Polymers from Plant Oils Linked by Siloxane Bonds for Programmed Depolymerization.

The increased production of plastics is leading to the accumulation of plastic waste and depletion of limited fossil fuel resources. In this context, we report a strategy to create polymers that can undergo controlled depolymerization by linking renewable feedstocks with siloxane bonds. α,ω-Diesters and α,ω-diols containing siloxane bonds were synthesized from an alkenoic ester derived from castor oil and then polymerized with varied monomers, including related biobased monomers. In addition, cyclic monomers derived from this alkenoic ester and hydrosiloxanes were prepared and cyclized to form a 26-membered macrolactone containing a siloxane unit. Sequential ring-opening polymerization of this macrolactone and lactide afforded an ABA triblock copolymer. This set of polymers containing siloxanes underwent programmed depolymerization into monomers in protic solvents or with hexamethyldisiloxane and an acid catalyst. Monomers afforded by the depolymerization of polyesters containing siloxane linkages were repolymerized to demonstrate circularity in select polymers. Evaluation of the environmental stability of these polymers toward enzymatic degradation showed that they undergo enzymatic hydrolysis by a fungal cutinase from Fusarium solani. Evaluation of soil microbial metabolism of monomers selectively labeled with 13C revealed differential metabolism of the main chain and side chain organic groups by soil microbes.

Exploring the substrate spectrum of phylogenetically distinct bacterial polyesterases.

The rapid escalation of plastic waste accumulation presents a significant threat of the modern world, demanding an immediate solution. Over the last years, utilization of the enzymatic machinery of various microorganisms has emerged as an environmentally friendly asset in tackling this pressing global challenge. Thus, various hydrolases have been demonstrated to effectively degrade polyesters. Plastic waste streams often consist of a variety of different polyesters, as impurities, mainly due to wrong disposal practices, rendering recycling process challenging. The elucidation of the selective degradation of polyesters by hydrolases could offer a proper solution to this problem, enhancing the recyclability performance. Towards this, our study focused on the investigation of four bacterial polyesterases, including DaPUase, IsPETase, PfPHOase, and Se1JFR, a novel PETase-like lipase. The enzymes, which were biochemically characterized and structurally analyzed, demonstrated degradation ability of synthetic plastics. While a consistent pattern of polyesters' degradation was observed across all enzymes, Se1JFR stood out in the degradation of PBS, PLA, and polyether PU. Additionally, it exhibited comparable results to IsPETase, a benchmark mesophilic PETase, in the degradation of PCL and semi-crystalline PET. Our results point out the wide substrate spectrum of bacterial hydrolases and underscore the significant potential of PETase-like enzymes in polyesters degradation.

Nanostructure characterisation of welded polyethylene using small angle X-ray scattering

Polyethylene (PE), a common thermoplastic polymer, is gaining prominence in the construction and packaging industries due to its exceptional mechanical properties, chemical resistance, safety, and integrity. However, internal defects can occur during manufacturing and throughout its service life. Neglecting this problem results in the disposal of plastic and, consequently, the accumulation of plastic waste and environmental issues, which have caused much criticism. A common method to repair the thermoplastics is welding, which introduces seams and localized thermal residual stress fields resulting in areas where damage can nucleate, potentially leading to cracks and failure over time. These cracks often start at the nanoscale and propagate to larger length scales until failure occurs. The objective of this research paper is to develop welding processes, with improved integrity and lifespan for PE. Additionally, it aims to investigate and assess the impact of PE welding on parent materials at nano- and micron-scales, to understand limitations that are challenging to overcome in such welding processes. The study involves joining PE panels together under various pre-heating and post-cooling conditions, followed by evaluating the environmental stress cracking resistance of the welds and the durability of the repaired components. The crystallinity and morphology of the PE material in the weld area and its surrounding regions were analysed using Small Angle X-ray Scattering (SAXS), and the findings were compared with results obtained from optical microscopy and Differential Scanning Calorimetry. The study concludes that SAXS results offer exceptional information about the parent PE and weld material within the welding zone.

Evaluating the Structural Performance of Concrete Beams Made of Waste Plastic Aggregates

Abstract: This study investigates the potential of using plastic waste as a partial replacement for aggregates in concrete production, aiming to address the dual challenges of unsustainable construction practices and the global accumulation of plastic waste. With an emphasis on sustainability and waste management, the research explores the effects of incorporating different percentages of plastic waste (0%, 5%, 10%, 15%, and 20%) on the mechanical properties, durability, workability, and thermal behavior of concrete. The methodology encompasses the collection and preparation of plastic waste, formulation of concrete mixes with varying levels of plastic waste replacement, and comprehensive testing of the prepared specimens for compressive strength, flexural strength, split tensile strength, workability (slump test), durability (freeze-thaw cycles), impact resistance, and thermal conductivity. The analysis of results reveals that while the inclusion of plastic waste in concrete leads to a reduction in mechanical strengths, it simultaneously improves workability, durability against freeze-thaw cycles, impact resistance, and thermal insulation properties

Maximizing waste plastic oil yield and enhancing energy and environmental metrics through pyrolysis process optimization and fuel modification

The accumulation of plastic waste poses a major environmental challenge, while the conversion of waste plastics into oil via pyrolysis holds promise as an alternative energy solution. Despite numerous investigations into this area, none have focused on optimizing pyrolysis process parameters for higher oil yield and enhancing the overall performance of plastic oil through suitable fuel modification. The present study aims to optimize the pyrolysis process parameters, including heating rate (HR), process temperature (PT), and reaction time (RT), to achieve a higher yield of waste plastic oil (WPO) and enhance the overall performance by blending optimal quantities of water. Fuel characterization and properties measurement were conducted using Fourier Transform Infrared and ASTM methods. WPO was blended with conventional diesel fuel (CDF) and different volume concentrations of water (5%, 10%, and 15%). The performance metrices were assessed under various engine conditions. The study findings indicate that the optimum condition of process parameters is an HR of 17.3 °C/min, PT of 403 °C, and RT of 96.30 min, and the fuel quality confirms its suitability as an alternative fuel source. The performance metrics revealed that WPO has a 5.4% lower brake-thermal efficiency than CDF, and the inclusion of 10% water in WPO (WPO10W) enhances the efficiency by 11.5%. The in-cylinder pressure and net-heat release rate of WPO are 1.3% and 12.9% lower than CDF, respectively, and WPO10W emulsion promotes efficient combustion. WPO10W emulsion fuel reduces oxides of nitrogen, hydrocarbon, and carbon monoxide emissions by 21.2%, 9.8%, and 22.2%, respectively, compared to WPO.

Microplastics contamination in aquaculture-rich regions: A case study in Gresik, East Java, Indonesia

The widespread use of plastic has resulted in the accumulation of plastic waste across a range of sizes, notably including microplastics (MPs). The introduction of MPs into aquatic ecosystems can lead to the contamination of organisms, mainly fish. This study reports for the first time a quantitative and qualitative analysis conducted on the abundance of MPs encountered in water and sediment of milkfish aquaculture ponds in Gresik, East Java, Indonesia. Water and sediment samples were collected at three stations between February to April 2021. The abundance of MPs was analyzed through the application of one-way ANOVA tests and Pearson's correlation analysis. The results identified four types of MPs: fragments, fibers, films, and pellets. The highest abundance of MPs in both water (10.40 particle/L) and sediment samples (1.15 particle/g) was observed in March. The predominant MPs size in the water samples is 100–500 μm, while it is below 100 μm in the sediment. The color of the MPs varied across eight colors: black, purple, red, blue, yellow, pink, green, and transparent. The identification of MPs polymers was found to be polypropylene (PP), Polyurethane (PU), Polycarbonate (PC), Polyethylene terephthalate (PETE), High-density polyethylene (HDPE), and low-density polyethylene (LDPE). The presence of MPs in the water column and sediments was correlated with human activities around the ponds. Hence, the abundance of MPs is a source of pollution that has the potential to damage the nutritional quality of farmed milkfish. This study provides important information for the local governments to develop waste management policies for a cleaner environment and improved human health.

Assessment and Sustainable Management Strategies for Plastic Waste in Can Tho City, Vietnam: A Circular Economy Approach

This study presents a comprehensive analysis of plastic waste accumulation in both terrestrial and aquatic environments in Can Tho city, Vietnam, a nation with high per capita plastic consumption and significant plastic waste discharge. Focusing on urban residential areas, riverside communities, suburbs, and rural regions, the research investigates the extent and impact of plastic waste in these diverse settings. Additionally, the study examines the accumulation of plastics at barriers, under bridges, and in the Hau River, identifying the predominance of single-use plastics and their environmental implications. The key findings indicate that the plastic waste leakage at land-based-source emission sites is substantial, with waste persisting for extended periods without effective clean-up. The study reveals a significant accumulation of plastics at barriers and bridge bases in aquatic environments, including along the river. The pollution level was observed to be more influenced by the quantity of waste rather than its mass per unit area, emphasizing the need for targeted waste reduction strategies. The study also identifies seven types of plastic, each associated with different sources of accumulation or settlement. This variety presents both challenges and opportunities for waste management and recycling. Significantly, the research underscores the potential of repurposing plastic waste into recycled products, aligning with the circular economy model. This approach not only extends the lifecycle of plastic products but also contributes to reducing plastic waste generation and minimizing the environmental impact. Overall, the findings highlight the urgent need for improved waste management practices in Vietnam, particularly in urban and riverside areas, and advocate for innovative recycling solutions to mitigate the environmental challenges posed by plastic pollution.

Integrating chemical and biological technologies in upcycling plastic waste to medium-chain α,ω-Diacid

The growing accumulation of plastic waste poses a pressing environmental challenge. Traditional disposal methods, such as incineration and landfilling, carry considerable health and ecological risks. In response, our study presents an innovative method to repurpose mixed plastic waste into valuable α,ω-diacids utilizing chemo-biological processes. We extracted pyrolysis oil, rich in hydrocarbons spanning a broad range of chain lengths (C7 to C32), from household plastic waste and employed a genetically engineered β-oxidation-blocked Candida tropicalis strain to convert this oil into α,ω-diacids of various chain lengths. Simple distillation at 200 °C enabled the extraction of medium-chain hydrocarbons from the pyrolysis oil. However, an increased ratio of medium-chain alkenes posed a toxicity challenge to the cells. Through hydrogenation, these medium-chain alkenes were fully converted to alkanes. Remarkably, cell growth was maintained even with an 8% concentration of hydrogenates. The subsequent biotransformation yielded medium-chain diacids, with 94.3% of the produced α,ω-diacids being of medium-chain length (C7 to C14). These results offer a novel and scalable solution for converting everyday plastic waste into valuable chemicals, thus significantly contributing to the circular economy and the advancement of sustainability goals.

Estuary Clean Up dalam Mendukung Pengelolaan Kawasan Pesisir Desa Sungai Nibung Kalimantan Barat

Desa Sungai Nibung is a coastal with high biodiversity, so this village has been designated as a conservation area in West Kalimantan with the main conservation target is mangrove. The mangrove ecosystem has an important ecological role, namely as a habitat for marine and coastal biota. A maintained ecosystem will protect the survival of the biota within it. Therefore, managing coastal areas is essential and a shared responsibility. One of the challenges faced in the management process in Desa Sungai Nibung is plastic waste pollution. This waste comes from disposal and runoff from land, which can enter rivers and the sea. Plastic pollution also comes from fishing activities, such as ship traffic, responsive fisheries, and cultivation. This waste needs to be appropriately managed because there is no final waste disposal site (TPA). Household waste and waste from several shops (plastic food and drink packaging) are dumped directly around the building. The accumulation of plastic waste will continue to increase. Therefore, cleanup activities were carried out to reduce plastic waste. Apart from that, this activity aims to educate activity participants about the negative impact of plastic waste on the environment. This community service activity was carried out by a lecturer in Marine Science, FMIPA, Tanjungpura University, who involved students from the Merdeka Belajar Kampus Merdeka (MBKM) program. Beaches and coastal clean-up from macroplastic waste are carried out in residential areas, docks, and areas near fishing activities and ecotourism areas. Implementation of PKM activities consists of permission and coordination, implementation, monitoring, and evaluation. The waste from activities varies from plastic bags, sachet packaging, and food containers to fishing lines. Plastic waste dominates compared to other waste. Participants' understanding concerning plastic waste pollution and its negative impact on the environment and aquatic organisms increased after the activity took place.

Assessing the environmental impact of plastic flows in urban areas: A life cycle assessment and scenario analysis study

Urban areas have a considerable impact on the environment. Among the sectors contributing to the environmental impacts is plastic product usage, resulting in urban plastic waste accumulation. There exists a need to determine and evaluate plastic flows and their environmental impacts in urban areas. Our research comprehended the modelling of the eight most commonly used plastic polymers in a system of a European city with 10^5 inhabitants for the year 2020. A scenario analysis was conducted, considering the European Union's policy of achieving a 65 % recycling rate by 2035. Plastic production contributes to most environmental impacts during the life cycle, where polyurethane, polystyrene and other plastic types are at the forefront. The results per waste management options revealed that recycling is still preferable for plastic waste, followed by incineration and landfill. Recycling potential was further noted during the scenario analysis, where an increased recycling fraction following the EU's policy could decrease the environmental impacts of global warming by a margin of 20 %–45 % and fossil resource scarcity by a margin of 20 %–52 % per individual plastic polymer. While the established model indicates potential benefits, improved data collecting, and further research are needed to improve the model and establish a plastic nexus within urban areas.

Identification and characterization of a fungal cutinase-like enzyme CpCut1 from Cladosporium sp. P7 for polyurethane degradation.

Plastic degradation by biological systems emerges as a prospective avenue for addressing the pressing global concern of plastic waste accumulation. The intricate chemical compositions and diverse structural facets inherent to polyurethanes (PU) substantially increase the complexity associated with PU waste management. Despite the extensive research endeavors spanning over decades, most known enzymes exhibit a propensity for hydrolyzing waterborne PU dispersion (i.e., the commercial Impranil DLN-SD), with only a limited capacity for the degradation of bulky PU materials. Here, we report a novel cutinase (CpCut1) derived from Cladosporium sp. P7, which demonstrates remarkable efficiency in the degrading of various polyester-PU materials. After 12-h incubation at 55°C, CpCut1 was capable of degrading 40.5% and 20.6% of thermoplastic PU film and post-consumer foam, respectively, while achieving complete depolymerization of Impranil DLN-SD. Further analysis of the degradation intermediates suggested that the activity of CpCut1 primarily targeted the ester bonds within the PU soft segments. The versatile performance of CpCut1 against a spectrum of polyester-PU materials positions it as a promising candidate for the bio-recycling of waste plastics.IMPORTANCEPolyurethane (PU) has a complex chemical composition that frequently incorporates a variety of additives, which poses significant obstacles to biodegradability and recyclability. Recent advances have unveiled microbial degradation and enzymatic depolymerization as promising waste PU disposal strategies. In this study, we identified a gene encoding a cutinase from the PU-degrading fungus Cladosporium sp. P7, which allowed the expression, purification, and characterization of the recombinant enzyme CpCut1. Furthermore, this study identified the products derived from the CpCut1 catalyzed PU degradation and proposed its underlying mechanism. These findings highlight the potential of this newly discovered fungal cutinase as a remarkably efficient tool in the degradation of PU materials.

Characteristics of bioplastics prepared from cassava starch reinforced with banana bunch cellulose at various concentrations

Human activities have led to the pollution of the environment through the accumulation of plastic waste. Since plastics are resistant to decomposition resulting negative impact on the environment, there is a pressing need for the development of bioplastics. Starch is a such of natural material that can be used made of bioplastics. However, bioplastics from starch were needed to improve starch-based bioplastics due to their brittle properties. To address this issue, researchers focused on enhancing starch-based bioplastics by incorporating cellulose, particularly derived from kepok banana bunch fibers and cassava starch variety UJ3. The production process involved adding varying concentrations of 2.5, 5, 7.5, and 10 % (wt) of kepok banana bunch cellulose. The findings indicated that increasing cellulose concentration improved the characteristics of the bioplastic materials significantly. The results showed that the addition of cellulose concentration improved the mechanical properties, water vapor absorption, and biodegradability of bioplastics. With an optimal cellulose concentration level at 7.5%, remarkable enhancements in tensile strength (from 2.92 to 6.72 MPa), reduced elongation percentage (from 20.89 to 4.06%), increased Young’s Modulus values (from 13.98 to 172.52 MPa), decreased water vapor absorption rate (from 15,93 to 11,48%), and enhanced bio-degradability rating (from 29,81 to 50,69%) were observed.
