Plastic Waste Management Strategies and Their Environmental Aspects: A Scientometric Analysis and Comprehensive Review.

Plastic consumption increases with the growing population worldwide and results in increased quantities of plastic waste. There are various plastic waste management strategies; however, the present management progress is not sustainable, and plastic waste dumping in landfills is still the most commonly employed strategy. Being nonbiodegradable, plastic waste dumping in landfills creates several environmental and human health problems. Numerous research studies have been conducted recently to determine safe and ecologically beneficial methods of plastic waste handling. This article performed a bibliographic analysis of the available literature on plastic waste management using a computational approach. The highly used keywords, most frequently cited papers and authors, actively participating countries, and sources of publications were analyzed during the bibliographic analysis. In addition, the various plastic waste management strategies and their environmental benefits have been discussed. It has been concluded that among the six plastic waste management techniques (landfills, recycling, pyrolysis, liquefaction, road construction and tar, and concrete production), road construction and tar and concrete production are the two most effective strategies. This is due to significant benefits, such as ease of localization, decreased greenhouse gas emissions, and increased durability and sustainability of manufactured materials, structures, and roadways. Conversely, using landfills is the most undesirable strategy because of the associated environmental and human health concerns. Recycling has equal benefits and drawbacks. In comparison, pyrolysis and liquefaction are favorable due to the production of char and fuel, but high energy requirements limit their benefits. Hence, the use of plastic waste for construction applications is recommended.

Chemical Recycling of Plastic Waste: Comparative Evaluation of Environmental and Economic Performances of Gasification- and Incineration-based Treatment for Lightweight Packaging Waste

Chemical recycling (CR) – in enabling the use of plastic waste back as secondary carbon feedstock for production – could play a complementary role to mechanical recycling in supporting the transformation from a linear to a circular carbon economy. To date, research has predominantly focused on assessing technological aspects associated with CR of pure plastic waste streams. Little is known about its potential for treating low-quality and mixed plastic waste fractions which are unsuitable for conventional recycling and are currently incinerated. To address this gap, this investigation utilizes an integrated approach comprising of life cycle assessment and techno-economic analysis to evaluate the environmental and economic performance of CR of lightweight packaging waste via waste gasification compared to direct and indirect incineration in Germany. Results show that CR can contribute significantly – irrespective of the energy mix – to reducing climate change, terrestrial acidification, and fossil resource scarcity. In terms of economic performance, findings suggest that while CR requires higher capital investment, a multi-pronged approach which encompasses upscaling, waiver of carbon dioxide certificate costs, and price premium for CR products could increase profitability of CR to incineration. This study provides empirical support for the potential contribution of CR to complement existing strategies to combat the plastic waste challenge, and insights into market conditions which could promote its economic attractiveness. Additionally, it provides comprehensive inventory data for conventional and alternative waste treatment plants for lightweight packaging waste to inform future research on systemic assessment of CR technologies and their contributions to a circular economy.

Analysis of Thermomechanical Properties of Polyethylene with Cement Addition.

The paper undertakes preliminary research towards the identification of the use of plastic waste, taking into account the possibility of increasing their mechanical strength and reducing flammability, as well as reducing the emission of harmful compounds to the atmosphere through the addition of cement. This is extremely important not only from the point of view of the wide use of plastic products in the industry, but also their thermal utilization. The present study deals with the aspect of the utilization of waste polyethylene (HDPE) as a matrix in composites with filler in the form of cement at 5 and 10%. The composite samples were prepared by injection molding after the prior proper mixing of the components. Comparative thermomechanical (DSC, tensile strength, DMTA), microstructure and flammability results are presented for HDPE samples and their composites with cement. It was found that the addition of cement as a filler to polyethylene made it possible to obtain composites with good thermomechanical properties.

Influence of Plastic Waste on the Workability and Mechanical Behaviour of Asphalt Concrete

The use of plastic waste as a bitumen extender added throughout the manufacturing process of asphalt concrete contributes value to that type of waste. Moreover, this type of polymer can improve some mechanical properties of asphalt concrete without weakening its workability and other mechanical characteristics too much. The study aimed to address these issues for four types of plastic waste, using different plastic contents added by the dry process and compared the results with a conventional mixture without plastic. A set of laboratory tests, such as volumetric parameter evaluation, the Marshall, gyratory compactor, and indirect tensile tests, repetitive four-point bending; and repetitive compression, assessed the workability and mechanical behavior of the studied materials. The results show that, although the addition of plastic waste reduces workability, the asphalt concrete retains satisfactory handling conditions. By adding plastic waste, the asphalt concrete becomes more elastic, and the stiffness values of the material are adequate to apply the material in a pavement surface layer. The resistance to fatigue cracking was at a suitable level for the asphalt mixtures studied. Adding the plastic waste in the study generally improved resistance to permanent deformation, although the performance was plastic type and content dependent.

Strategies for Waste Recycling: The Mechanical Performance of Concrete Based on Limestone and Plastic Waste

Recycling is among the best management strategies to avoid dispersion of several types of wastes in the environment. Research in recycling strategies is gaining increased importance in view of Circular Economy principles. The exploitation of waste, or byproducts, as alternative aggregate in concrete, results in a reduction in the exploitation of scarce natural resources. On the other hand, a productive use of waste leads to a reduction in the landfilling of waste material through the transformation of waste into a resource. In this frame of reference, the paper discusses how to use concrete as a container of waste focusing on the waste produced in limestone quarries and taking the challenge of introducing plastic waste into ordinary concrete mixes. To prove the possibility of reaching this objective with acceptable loss of performance, the mechanical characteristics of concrete mixed with additional alternative aggregates classified as waste are investigated and discussed in this paper through the presentation of two experimental campaigns. The first experimental investigation refers to concrete made with fine limestone waste used as a replacement for fine aggregate (sand), while the second experimental program refers to the inclusion of three types of plastic wastes in the concrete. Different mixes with different percentages of wastes are investigated to identify possible fields of application. The experimental results indicate that use of limestone quarry waste and use of plastic waste are possible within significant percentage ranges, having recognized a limited reduction of concrete strength that makes concrete itself appropriate for different practical applications.

Utilization of recycled PET plastic waste as replacement of coarse aggregate in pervious concrete

This study aimed to determine the effects of using plastic waste as a natural coarse aggregate replacement in pervious concrete with different sizes of coarse aggregate. The plastic waste used in this experiment was of the Polyethylene Perephtalate (PET) type obtained from the mineral water bottles. The plastic waste was formed to be similar to the natural coarse aggregate sizes of 5–10 mm and 10–20 mm, replacing 5% of the coarse aggregate in pervious concrete. In order to obtain the appropriate proportions, three ratios of aggregate: cement (2:1, 3:1, and 4:1) were used in the preliminary experimental stage. The aggregate: cement ratio of 3:1 was then evaluated by including the addition of the recycled PET plastic aggregate in the compressive strength and void ratio tests. Based on the results, it was found that the pervious concrete containing 5% of recycled plastic aggregate improved on the 7th day in terms of compressive strength. However, on the 28th day, the compressive strength was observed to be comparable with the pervious concrete. The void ratio test showed that the use of plastic waste can increase the percentage of connected voids compared to the pervious concrete control. Furthermore, the use of recycled PET plastic waste, when properly proportioned and treated, can be used in pavement areas and other forms of construction where there are light loads.

Investigating Mechanical Performance of Ravelling in Hot Mix Asphalt Containing Plastic Waste

One of the road damages on the flexible pavement is ravelling. Ravelling caused by the release of aggregate grains from the asphalt mixture. The interaction between the wheels of the vehicle and the surface of the pavement causes friction that pushes the aggregate out. The plastic waste on road pavements has been widely used to improve the performance of road pavement structures. Most of previous study focused on Hot Mix Asphalt (HMA) ravelling using Cantabro test. The purpose of this study was to investigate the ravelling performance of plastic waste material in hot mix asphalt mixtures. In addition, the use of plastic waste can reduce the environmental impact due to the high volume of plastic waste. The test is carried out in the laboratory using a rotation abrasion device based on the principle of rotating wheel load with loading, speed, and testing time parameters. Furthermore, the ravelling resistance value of HMA was obtained in dry and wet conditions. The addition of plastic waste into asphalt can increase the ravelling resistance of HMA mixes. The results of the wet test have greater ravelling resistance than dry test.

Experimental study of the thermal and mechanical properties of concrete incorporating recycled polyethylene

The widespread use of plastics worldwide generates a large amount of plastic waste that needs to be recycled to minimize its negative impact on the environment. The use of plastic waste as a partial replacement for traditional aggregates remains a solution not only to reduce the amount of plastic waste but also to reduce the overexploitation of natural resources such as quarries. The objective of this paper is to evaluate the mechanical and thermal properties of concrete containing 0%, 5%, 10%, and 15% polyethylene waste (PEW) particles as a partial replacement of coarse aggregates. Several experiments were conducted to evaluate workability, density, compressive strength, and thermophysical properties. The results show that the substitution of recycled PE for coarse aggregate in concrete improves thermal insulation, which leads to the potential use of these concretes as construction materials with many environmental benefits.

A study on interlocking brick innovation using recycled plastic waste to support the acoustic and thermal performance of a building

The main materials used in producing interlock bricks are clay, sand, and cement as usually applied in the conventional process of making bricks. There is, however, a continuous reduction in the availability of these natural resources due to their non-renewability. Therefore, one of the materials with the ability to support the acoustic and thermal performance of buildings in architecture is plastic. Plastics are categorized as lightweight, non-breakable, non-corrosive, and resistant to weather. Moreover, there is no need for the production of new plastics for this purpose due to the global call for the use of plastic wastes based on their high economic value. Therefore, this research aimed to compile a study on interlock brick innovation using recycled plastic waste to support the acoustic and thermal performance of a building. This was conducted through a review of previous studies on the profile of interlock bricks produced from recycled plastic waste. The findings are expected to provide information on the efficient production of interlock brick innovation using plastic wastes as a component.
