What is it about?
The plastic wastes can be retrieved back for conversion to value added petrochemicals including aromatic char, hydrogen, synthesis gas, and bio-crude oil using various technologies including thermochemical, catalytic conversion and chemolysis.

Why is it important?
Plastic production and its unplanned management and disposal, has been shown to pollute terrestrial, aquatic, and atmospheric environments. Petroleum-derived plastics do not decompose and tend to persist in the surrounding environment for longer time. Plastics can be ingested and accumulate into the tissues of both terrestrial and aquatic animals, which can impede their growth and development.
Perspectives
At present, a few developed countries have implemented legislative and policy approaches to reduce plastic manufacture, consumption, and waste generation and to increase their reuse. However, advocating these strategies for combined plastic waste management and formulating a universal approach to address different types of plastic wastes are challenging. Thus, potential plastic waste management strategies to address the global plastic pollution problem must begin with a sustainable infrastructure development, followed by socially acceptable and economically feasible valorisation technologies or policy regulations.
