Chemicals and waste

This event primarily focusses on SDG 9 (industry, innovation and infrastructure), exploring the technical and engineering challenges of addressing all 17 Sustainable Development Goals.
Contributing to SDGs 7, 9 and 12, this critical literature review surveys the existing environmental life cycle assessment (LCA) studies on grid-scale stationary lithium-ion battery energy storage systems, and highlights research gaps concerning comprehensive environmental impacts. Several recommendations for future stationary storage LCA studies are proposed.
This paper focuses on the integration of a pregnant leach solution (PLS) - derived from a NiMH recycling stream - into a nickel production plant. Although toxic Cd is not present in NiMH batteries, it ends up in the battery waste stream, preventing direct integration of the waste into the primary process. This study removed Zn, Fe, Al, Mn and Cd ions from the PLS using a two-step solvent extraction process, so that the Ni and Co remaining in solution could be integrated into the nickel production process, addressing SDGs 7, 9 and 12.

Cathode-healing™ is a direct recycling method that restores structure and functionality to well-used lithium-ion cathodes. The study shows restoration of two EV-relevant chemistries: NCM 523 and NCM 622. Full cells composed of recycled material demonstrate lifetime capability on par with baseline material. The technical feasibility and low-cost of cathode-healing™ enables sustainability in the electric vehicle and energy storage industries, addressing SDGs 7, 9 and 12.

Contributing to SDGs 7, 9 and 12, this paper explores the possibility for safe discharge of cells using different salt solutions. Corrosion of the cell terminals was limited with bicarbonate and hydrogen phosphate salts. These salts shows a marked improvement in safety when compared to sodium chloride brine discharge, where the cells are compromised within minutes.
This book chapter addresses goals 9, 12 and 15 by looking at how green nanotechnology can facilitate sustainable methods leading to reduced environmental impacts, improved conservation, and the protection of resources and human health.

This research develops SDGs 9 (industry, innovation and infrastructure), 14 (life below water) and 15 (life on land). A new recycling process of the common plastic polyethylene terephthalate (PET) could help with the urgent problem of ever-increasing amounts of plastic waste in our oceans and the environment.
This article explores a previously overlooked form of microplastic pollution. Directly relevant to SDG 12 (responsible consumption and production), SDG 15 (life on land) and SDG 14 (life below water), this research investigates the interactions between tire derived microplastics and organic matter within the environment.
This study compares different microplastic sampling methods for water, sediment and biota. This supports SDGs 9.5 (enhanced scientific research) 12 (responsible consumption and production) and 14 (life below water).
