“…Indeed, some plastic wastes cannot be recycled (e.g., composites, highly degraded materials) and should have an alternative end-life besides landfilling (Braungart et al, 2007). The use of recycled plastics is currently also hindered by the low costs of virgin materials, which could be overcome through the implementation of taxes or minimum requirements for the use of recycled materials (Singh and Ruj, 2015). In the use of disposable PPE by the public, end-of-life strategies need to be rethanked regarding the proper disposal in sealed impermeable bags or neutralised through sterilising techniques.…”

“…There is a demand for improvements in design, which also benefit companies by reducing requirements for raw materials, and for viable alternatives, which are still limited. Recycled are more expensive than virgin plastics, however they are beneficial at an environmental and societal level [38] and thus should be encouraged by voluntary (as a marketing strategy) or mandatory incorporation of percentage of recycled materials (e.g., 10% of weight), which cannot be too high due to losses in each recycling cycle [39].…”

“…Reformulation of plastics into feedstocks uses energy to recover constituents that can be used to produce fuels similar to gasoline (waste-to-energy) or to produce chemicals, lubricants, and carbon black [34,37,106,118]. Pyrolysis, an endothermic cracking process without oxidation, and gasification, a similar process with partial oxidation [38], are efficient in producing fuels from plastic waste with similar physicochemical properties and costs as gasoline, especially when produced in the presence of catalysts [118]. Besides fuel production, valorization may come from by-products, such as using carbon black to improve asphalt [106], or by producing value-added substances, such as carbon nanotubes produced from plastic waste at a lower cost and with lower CO 2 emissions [119].…”

“…Landfills are part of a linear waste management but also take part in an integrated management as end-of-life residues are produced by recycling and incineration [38]. Nonetheless, they should always be the last option because of higher environmental impact, higher risk of contamination, loss of resources, and land requirements [37].…”

Plastic pollution is generated by the unsustainable use and disposal of plastic products in modern society, threatening economies, ecosystems, and human health. Current clean-up strategies have attempted to mitigate the negative effects of plastic pollution but are unable to compete with increasing quantities of plastic entering the environment. Thus, reducing inputs of plastic to the environment must be prioritized through a global multidisciplinary approach. Mismanaged waste is a major land-based source of plastic pollution that can be reduced through improvements in the life-cycle of plastics, especially in production, consumption, and disposal, through an Integrated Waste Management System. In this review paper, we discuss current practices to improve life cycle and waste management of plastics that can be implemented to reduce health and environmental impacts of plastics and reduce plastics pollution. Ten recommendations for stakeholders to reduce plastic pollution include (1) regulation of production and consumption; (2) eco-design; (3) increasing the demand for recycled plastics; (4) reducing the use of plastics; (5) use of renewable energy for recycling; (6) extended producer responsibility over waste; (7) improvements in waste collection systems; (8) prioritization of recycling; (9) use of bio-based and biodegradable plastics; and (10) improvement in recyclability of e-waste.

“…At present, USA has the highest consumption of plastic equal to 39 MT. With the rapid growth of India produces 15000 tonnes/day, it is expected to rise to 24 MT by 2020 (Das and Tiwari, 2018;Singh and Biswajit, 2015). Plastic is a non-biodegradable material, subject to throw away culture and lack of an efficient waste management system it becomes socially concerned to dispose it safely.…”

Plastics are the dominant part of waste. Recycling is a major challenge beside avoiding of plastic consumption. Development of economic catalysts is a crucial factor to provide cost effective recycling of plastics into fuels. The primary objective of this research is to use pure metallic nanoparticles and modified south Asian clay. These composite catalysts were investigated for the effectiveness and degradation of polymers into liquid fuels and compared their activity with commercially available catalytic material. A series of reactions were conducted in a 25 cm3 autoclave reactor under different conditions such as temperature, catalyst load, addition of active metals, and with nickel nanoparticles. The products distribution for the pyrolysis reactions were determined and compared with commercial kerosene, gasoline and diesel. Clay catalyst gave good liquid yield at 350 °C for low-density polyethylene and post-consumer poly-bags. 10% impregnation of nickel on natural clay gave maximum liquid yield 79.23% for LDPE, while for poly- bags it reached up to 76.01%. The amount of liquid yield was found to increase to 12% and 18.6% for LDPE and poly-bags, respectively on the impregnation of nickel on clay compared to neat clay. It could be demonstrated as well that nickel nanoparticles and molybdenum impregnation on clay give a good yield on liquid fuel. The final products are in the range of gasoline, kerosene and diesel.
