“…2,3 PS products cannot be reused or recycled and hence they cause severe environmental problems as they are non-biodegrdable. 4 Used polystyrene waste such as thermocol is generally disposed by land filling and also it cannot be incinerated, since the evolved gases of polycyclic aromatic hydrocarbons are highly toxic. 5,6 Recycling of expanded polystyrene (EPS) is not affordable commercially because of the low value of recycled goods and difficulties in the collection and storage.…”

Polymer composite film containing expanded polystyrene wastes, poly (ethylene-co-vinyl acetate), epoxidized neem oil and cassava starch was prepared by solution casting technique. The composite film was characterized by FTIR, NMR, X-ray diffraction, and FESEM analysis. The thermal stability of the polymer composite film was studied by TGA and DSC. Melting point, glass transition temperature and cold-crystallization temperature of the composite films were found to decrease with increasing percentages of epoxidized neem oil plasticizer, which point towards the enhanced segmental mobility of the polymer chain. TGA results show that plasticization has enhanced the thermal stability of the polymer composite. The prepared films show improved percentage elongation with moderate tensile strength and Young’s modulus. Soil burial test was adopted to check the biodegradability. The lower values of water absorption indicate the water-resistant nature of the films. This green synthetic approach offers a simple means of up-cycling waste thermocol in a cost-effective manner which imparts partial biodegradability with potential for packaging film and eliminates the usage of toxic chemicals.

Strategic Approach Towards Plastic Waste Valorization: Challenges and Promising Chemical Upcycling Possibilities

Plastic waste, which is one of the major sources of pollution in the landfills and oceans, has raised global concern, primarily due to the huge production rate, high durability, and the lack of utilization of the available waste management techniques. Recycling methods are preferable to reduce the impact of plastic pollution to some extent. However, most of the recycling techniques are associated with different drawbacks, high cost and downgrading of product quality being among the notable ones. The sustainable option here is to upcycle the plastic waste to create high-value materials to compensate for the cost of production. Several upcycling techniques are constantly being investigated and explored, which is currently the only economical option to resolve the plastic waste issue. This Review provides a comprehensive insight on the promising chemical routes available for upcycling of the most widely used plastic and mixed plastic wastes. The challenges inherent to these processes, the recent advances, and the significant role of the science and research community in resolving these issues are further emphasized.
