AbstractPlastic pollution is a pressing issue because authorities struggle to contain and process the enormous amount of waste produced. We study the potential for reducing plastic waste by examining the efficiency with which different polyethylene terephthalate (PET) bottles deliver beverages. We find that 80% of the variation in bottle weight is explained by bottle capacity, 16% by product category, and 1% by brand. Bottle weight is quadratic and convex function of capacity, which implies that medium capacity bottles are most efficient at delivering consumable product. Local data on PET bottle sales and municipal waste recovery validate the findings. A 20% shift in consumption from smaller to larger bottles could reduce the production of PET waste by over 10,000 t annually in the U.S. alone.

PET plastic waste is found everywhere in Banjarbaru City compared to other plastic wastes. It is an excellent prospect to reuse the PET plastic waste. The demand of mountain rock and stone from natural resources increases as happened in Aranio Sub District, Banjar Regency. This research is expected to find one way of suppressing the growth of the number of stone mines or natural stone. Based on SNI 03-0691-1996, the classification of the paving block differentiated according to its usage class, one of which is the C quality used by pedestrians. PET waste used as a coarse aggregate previously processed into aggregate with the ratio of cement material, fine aggregate, a coarse aggregate of 1:6:4. PET waste is processed by melting PET and forming into aggregates. The paving with PET waste process by a hydraulic press machine and tested for strength after 28 days. The result of weight measurement with the specimen increases the amount of PET in the paving block mixture, the paving weight decreases as well as the compressive strength.

Plastic waste can be handled with several traditional waste management strategies, including landfilling, incineration, and recycling. Several novel strategies for recycling plastic waste have been proposed and researched for practical use, however the sustainability of the novel processes have not been analyzed in detail. This paper outlines a strategy for recycling polyethylene terephthalate (PET) waste through pyrolysis. A sustainability assessment of the process is conducted to analyze the environmental, economic, and social performance of recycling PET waste into crude oil. Environmental performance is evaluated using life cycle assessment, and the ReCiPe, cumulative energy demand (CED), and cumulative exergy demand (CExD) impact assessment methods. Net present value analysis is used to assess the economic impacts of the process. To complete a holistic sustainability assessment, social benefits and impacts are presented through a qualitative review of the process. In addition, an environmental impact analysis of the production of virgin PET using the recovered crude oil is presented and compared with traditional virgin PET production in terms of sustainability performance metrics. CED and CExD impact results emphasize the conceivable evidence of plastic waste as an energy source. The research highlights the use of standardized impact assessment methods to realize the environmental, economic, and social benefits of recycling PET into crude oil. Furthermore, a review of various process improvements broadens the potential for optimization of the novel process to further elucidate the benefits of plastic recycling.

It is widely accepted that plastic waste is one of our most urgent environmental concerns the world is currently facing. Plastic has contributed greatly to innovation in all fields, but the raw material for its production (fossil fuels), as well as the linear economy in which it is currently produced and used, makes the material problematic from a sustainability and human health perspectives. The emergence of bio-based plastics provides an opportunity to reduce dependency on fossil fuels and transition to a more circular plastics economy. For polyethylene terephthalate (PET), one of the most prevalent plastics in packaging and textiles, there exist two bio-based alternatives that are similar or superior in material property and recyclability. These are polyethylene furanoate (PEF) and polytrimethylene terephthalate (PTT). The overarching aim of this study was to examine the transition from fossil-based to renewable plastics, through the lens of PET upcycling into PEF and PTT. The process for the production of PEF and PTT from three feed streams (post-consumer PET waste, lignocellulosic biomass-derived cellulose and biodiesel-derived crude glycerol) was developed in the software SuperPro Designer and the economic viability assessed via a discounted cumulative cash flow (DCCF) analysis. This study represents a conceptual case study of the valorisation of existing plastic waste into new, recyclable bio-based plastics, for a more sustainable plastics production. A techno-economic analysis of the designed process revealed that the minimum selling price (MSP) of second generation-derived PEF and PTT is 3.13 USD/kg, and that utilities and the feedstock used for the production of 2,5-furandicarboxylic acid (FDCA) needed in PEF synthesis contributed the most to the process operating costs. The effect of recycling PEF and PTT through the process at three recycling rates (42%, 50% and 55%) was investigated and revealed that increased recycling could reduce the MSP of the 2G bio-plastics (by 48.5%) to 1.61 USD/kg. This demonstrates that increasing recycling rates would have a beneficial effect on the economic viability of the plastic biorefinery.

Background: Plastic waste (PW) is becoming increasingly hazardous to the environment as a result of its massive production, causing significant damage to both the ecosystem and its inhabitants. Managing plastic waste is a global concern due to its non-biodegradable nature. However, it is important to handle PWs properly to curtail the environmental emissions associated with their incineration and dumping into landfills. This research investigates the possibility of producing tiles from polyethylene terephthalate (PET) waste bottles and fly ash. The mechanical properties, as well as the chemical resistance of the manufactured PET polymer tiles, are reported in this study. Methods: PET waste was used in varying proportions (from 30% to 100%) by sand weight. The shredded PET waste was heated at 230 oC before being suitably blended with fly ash. It was then poured into the designated mold, removed after one hour, and cooled for 24 hours before testing. Results: The assessment of the physical and mechanical properties of the materials revealed that the tiles produced with 30% PET content performed better in terms of material density and strength compared to the samples with higher PET content. The highest compressive strength being 6.88 MPa. Based on the results of the tests, the produced PET tiles have a low water absorption efficiency of 80% lower when compare to cement and ceramic tiles (the water absorption values are between 0.98% and 0.09%). Conclusions: The results from this study indicate that PET waste bottles can be used to produce long-lasting, durable, and extremely low water absorption eco-friendly tiles for both residential and commercial applications. This prospect of tile production using polyethylene terephthalate (PET) waste and fly ash would not only minimize the cost of building products but will also act as a waste diversion to mitigate environmental emissions caused by plastic waste disposal.

Abstract Plastics are a vast group of synthetic or semi-synthetic materials that are often made of polymers. Because of their plasticity, plastics can be molded, extruded, and pressed into solid objects of different sizes. Its extensive use is due to its flexibility, as well as a number of other properties such as light weight, durability, and low manufacturing costs. The high use of plastics has resulted in an increase in solid waste, with domestic waste accounting for a significant portion of it. Since this waste is not biodegradable and takes up a lot of space, it is considered a serious environmental problem. To overcome these adverse effects, recycling plastic waste and using it in concrete can be an effective way to protect the environment. In this study, an attempt was made to experimentally evaluate the mechanical properties of concrete with recycled PET plastic wastes. The effect of this type of plastic waste was investigated by adding it in three different lengths: 22 mm, 45 mm, and a combination of both lengths 22 + 45 mm. For each length of fiber, it was added in three percentages to concrete 0.1, 0.3 and 0.5 % of cement weight. Several experiments were carried out on concrete mixtures such as slump test, compressive test, splitting tensile test, flexural test, and ultrasound pulse velocity test. The findings showed that PET waste in the form of fibers could be incorporated into concrete and achieve adequate compressive strength. When the ultrasound test results were compared to the results of previous tests, it was discovered that normal concrete containing plastic waste in the form of fibers performed exceptionally well.
