“…These processes also revolve around the concept of oils and HC cracking to achieve the desired products acceptable to the marketplace and standards (Al-Salem, 2019; Chandrasekaran and Sharma, 2019a; Vasile et al, 2001). Further upgrading for the generated products can also be achieved with catalytic reforming in the petroleum downstream industry (Hafeez et al, 2019; Muhammad et al, 2015; Sharma and Bansal, 2016; Sharma et al, 2014; Sharuddin et al, 2016). All of which combined can lead to the accumulation of spent catalysts that is not typically accounted for in integrated solid waste management (ISWM) surveys, strategy development and studies.…”

Industrial solid waste management encompasses a vital part of developed and developing countries strategies alike. It manages waste generated from vital industries and governs the hazardous waste generated as a major component of integrated waste management strategies. This article reviews the practices that govern the management approaches utilized in the developed world for industrial spent catalysts. It critically assesses the current situation of waste management within the developing world region focusing on the industrial waste component, in a novel attempt to crucially develop a strategy for a way forward based on best practices and future directions with major European industries. The review also draws parallels with European countries to compare their practices with those of the State of Kuwait, which rely solely on landfilling for the management of its industrial waste. Spent catalysts recovery methods are discussed at length covering conventional methods of valuable metals and chemicals recovery (e.g., hydrometallurgical, solid–liquid and liquid–liquid extraction) as well as biological recovery methods. A major gap exists within regulations that govern the practice of managing industrial waste in Kuwait, where it is essential to start regulating industries that generate spent catalysts in-view of encouraging the establishment of valorization industries for metal and chemical recovery. This will also create a sustainable practice within state borders, and can reduce the environmental impact of landfilling such waste in Kuwait.

“…[54] There are many reviews that cover the pyrolysis, hydrocracking, and gasification of plastic waste with emphasis on the technique (i. e., operating conditions) and specific end product.

This review aims to draw a connection between the impact of the textural properties of the catalyst and its performance for plastic conversion with hopes that this can be a useful resource for the development and design of future improved plastic waste conversion catalysts.…”

“…Thermal cracking is attractive because it can be carried out locally at waste collection and plastic segregation points with technologies that are environmentally friendly while yielding desirable materials [27] . The product outcome is largely dependent on the process conditions (i. e., temperature) and composition of the plastic waste and because of this, the production of low molecular weight materials requires high operation temperatures ( T >500 °C) [2,6,11,12,14–16,23–52] . Along with the dependence on pyrolysis temperature, thermal cracking yields a broad range of hydrocarbons with respect to the carbon number, making the large‐scale production of renewable materials (the main goal of the circular economy), transportation‐quality fuels (secondary products), and valuable chemicals difficult.…”

Plastic pollution is a global issue that severely threatens the environment if not managed properly. Plastic waste is widely treated in unsustainable ways such as landfill and incineration that generally do not contribute to the circular economy or to the principles of the United Nation's sustainable development goals. Catalytic pyrolysis of plastic waste is considered an alternative solution with its potential of recovering fuels and chemicals from the plastic waste that is not recyclable. Here, we described for the first time the main steps required for running an operational pyrolysis plant from a whole system perspective. The recent advancement of plastic pyrolysis technologies is also described to guide the selection of relevant catalysts. The practical applications of products from the plastic pyrolysis are succinctly reviewed. This review will facilitate the development of the capacity to make better decisions upon the design and analysis of plastic pyrolysis processes and systems.This article is categorized under: Sustainable Energy > Bioenergy Climate and Environment > Circular Economy Emerging Technologies > Materials Sustainable Energy > Energy Efficiency
