Global plastic pollution is a negative impact on the environment as the production and use of plastic are increasing rapidly. Plastic recycling is a significant step towards a circular economy. Over the decades, much plastic has been in circulation for various applications. Recycling plastic wastes (PW) entails waste sorting using some physical properties including plastic types, colors, and shapes, to produce high-quality recycled plastics. Classification of PWs includes common plastic types: Polyethylene terephthalate (PET), High-density polyethylene (HDPE), Polyvinyl chloride (PVC), Low-density polyethylene (LDPE), Polypropylene (PP), Polystyrene (PS), and others. The traditional method of sorting PW achieves good accuracy but low throughput at an excessive cost. Automated processes in plastic sorting are developed to overcome this. This study analyzes automated sorting techniques and examines bibliometric data on plastic waste research over the past four decades. The Scopus database was used to retrieve statistics on the subject, which were then examined using the bibliometric program in the VOSviewer software. The data visualization was also carried out with VOSviewer. The results of this study can guide future research and provide crucial details to improve plastic waste management.

“…According to Etengeneng [5] insufficient waste management practices, lack of adequate recycling incentives as well as public knowledge, and ineffective by law enforcement all have an impact on MSW. Furthermore, the ineffective methods of disposing of solid waste have detrimental effects on human health and the environment that go beyond their borders, contaminating adjacent water supplies and acting as disease breeding grounds [11]. Despite these difficulties, it should be noted that several African nations set goals that aim to put into practice efficient waste management techniques and strategies such as, anaerobic digestion, composting, and recycling [11].…”

The quality of the waste, which influences emissions from landfills, the quality of incineration residues, and other waste management characteristics, may be significantly impacted by variations in MSW composition [7].…”

Management of municipal solid waste (MSW) is a serious environmental challenge that many nations, particularly developing ones are currently experiencing. As a result, information about the amount and type of MSW is needed to establish an effective waste management strategy. In addition, the amount and type of MSW may change from place to place and season to season. Thus, the purpose of this study was to determine the amount of MSW recovered in the O.R. Tambo District Municipality, Eastern Cape, South African. The first objective of this study was to determine the effect of season on the amount of each waste type (aluminium cans, bottles, cardboards and plastics) recovered. The second objective was to compare the amount of each waste type recovered among the five local municipalities (Ingquza Hill, King Sabatha Dalindyebo, Mhlontlo, Nyandeni and Port St. Johns (PSJ)). The study, which focused on MSW recovered over a two-year period (September 2019 to August 2021), revealed that there were no statistically significant differences in the amount of MSW recovered among the four seasons. However, the type of waste recovered mostly varied significantly across the local municipalities. For example, PSJ had the highest recovery of bottles, while Mhlontlo had the highest recovery of other types of waste. We can conclude that solid waste recovery is crucial since it reduces the amount of waste that must be disposed of in landfills and saves more natural resources.

“…In 2016, the Europe and Central Asia region produced 395 million tons of waste, or 1.21 kg per person per day [17]. Only 33% of waste materials are currently recycled or composted, although around 75% of this waste has the potential to be recovered through these methods.…”

The aim of this study is to explore the application trend of the circular economy and research on plastic waste recycling by comparing results from selected databases. The methodology involves developing a bibliometric study based on data from Scopus and the Web of Science Journals & Country Rank, spanning from 2014 to 2023. A total of 2,083 articles were retrieved from these two research databases, with 1,108 and 975 articles coming from Scopus and WoS, respectively. Descriptive bibliographic maps and strategic charts, generated by OriginPro, Excel, and VOSViewer, are presented. The Circular Economy (CE) is a model that eliminates waste, adopts sustainable practices, closes loops in industrial ecosystems, and turns end-of-life products into resources for others. This stands in contrast to the linear economy, which disposes of waste through landfill or incineration. Currently, plastic production is still supported by a resource-intensive paradigm that decouples economic growth from resource consumption. The annual consumption of plastic materials and fossil fuel is projected to triple by 2050, a trend that has attracted significant attention. The introduction of CE has drastically reduced resource consumption. This study compares the Scopus and Web of Science databases regarding current plastic use and recycling of plastic waste. Moreover, it identifies the future contribution of the degrowth economy in managing plastic waste for recycling.
