Chemicals and waste

Contributing to SDGs 7, 9 and 12, this study shows that cathode-healing™ restores structure and functionality to well-used lithium cobalt oxide. The paper follows recycling activities from the collection of battery packs, through to extraction of electrolyte with carbon dioxide, industrial shredding, electrode harvesting, froth flotation, cathode-healing™ and finally, building new cells with recycled cathode and anode. The final products demonstrated useful capability in the first full cells made from direct recycled cathodes and anodes from an industrial source.
This book chapter addresses goals 9 and 12 by describing recycling methods including primary, mechanical, chemical and quaternary, to create new valuable products from plastic wastes and keep them out of landfill.

Hazardous waste generated from the disposal of Lithium-ion batteries (LIBs) is driving research into a sustainable approach for treatment and recovery. The positive electrode active materials are the main targeted component, being the greatest contributor to LIBs cost. This paper studies the particle size characteristics of milled spent LIBs, and also the interaction of copper and aluminum impurities based on size, contributing to SDGs 7, 9 and 12.

Contributing to SDG 9 (industry, innovation and infrastructure) and environmental SDGs 12, 13, 14 and 15, this piece explores the vast amounts of organic solvents employed in carrying out organic reactions with the chemistry industry and explores alternatives with reduced negative environmental impact.
Advancing goals 3, 12, 14 and 17, this article proposes an informed plan for countries to work together for the safe and responsible use of chemicals.

Contributing to SDG's 12 (responsible consumption and production) and 15 (life on land), this review explores scientific progress in analytical methods, pollution characteristics and ecological effects of microplastics in soils.

This microplastics special issue compiled by Trends in Analytical Chemistry supports many of the SDGs, namely SDGs 3 (good health and well-being), 9.5 (enhance scientific research), 12 (responsible consumption and production), 14 (life below water) and 15 (life on land).
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.
