Under the parent petrochemical industries, plastic industry is proliferating enormously over the past several years globally due to its advantages in terms of weight, robustness, expense, versatility, and durability. Due to the diversified consumer base representing varied climate zones, food habits, and standards of living, the generation and growth opportunities for the plastic industry in India are particularly distinct and humongous. The present work extensively reviews the Indian plastic industry with primary focus on the evolving technologies for plastic waste valorization encompassing their level of utilization, technology readiness, and progress achieved at R&D level. The study attempts to recognize different issues related to technology, recycling, policy, research, regulation that should be given attention to formulate an improved plastic waste management strategy in the region. Though significant shares of waste plastics in the country are processed by traditional practices, state-of-the-art technologies primarily plastic to oil conversion, in road making and in cement manufacturing, are being deployed at increasing rate. Action to tackle the problem of plastic contamination in India will need to adopt a pan India strategic consensus/concurrent approach for effective waste collection and segregation with active participation of urban local bodies, fixing the role of the informal sectors, investment for reliable technology adoption with skilled manpower for operation, adoption of circular economy schemes involving plastic waste co-processing, and providing support to work on R&D for better penetration of the proven plastic valorization options along with their environmental and social implications.

Antimony is a critical raw material in Europe wherein for 43% of its market share it is applied in the form of antimony trioxide as a fire retardant in plastics. Currently, antimony recycling from waste plastics does not take place and has been scarcely studied. In this work, a process was developed to extract antimony from a soft PVC material and recover it as SbClO.

We investigated the amount and distribution of waste generated by commercial tobacco, electronic cigarette, and cannabis (TEC) use to inform policy options aimed at mitigating the environmental harm caused by these products. Using disproportionate stratified random sampling, we selected 60 census blocks from the eight largest cities in San Diego County, California. We twice surveyed publicly accessible areas in these blocks to quantify TEC waste accumulation and its re-accumulation.

Microplastic (MP) contamination poses significant risks to ecosystems and human health. However, the absence of standardized protocols, detailed polymer identification, and sources identification hinders the development of targeted mitigation strategies, particularly in developing nations. There is a scarcity of comprehensive data on MP distribution, sources, and transport mechanisms in freshwater environments.

Polyurethanes are an important class of synthetic polymers, widely used in a variety of applications ranging from everyday items to advanced tools in societal infrastructure. Their inherent cross-linked structure imparts exceptional durability and flexibility, yet this also complicates their degradation and recycling. Here we report a heterogeneous catalytic process that combines methanolysis and hydrogenation with a CO/H reaction medium, effectively breaking down PU waste consisting of urethane and ester bonds into valuable intermediates like aromatic diamines and lactones.
