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.
This journal article addresses goals 7, 12, 13 and 15 by discussing how the rising demand for renewable resources has increased silage maize production which has adverse environmental effects and therefore limits the advantages of renewable biomass.

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.
Energy consumption of the residential sector in Oman was examined and forecasted. A validated simulated model of a typical Omani house was compared to an energy-efficient one. This was done in three climatic zones in Oman using four GCC energy codes. Saving ranged between 13.2%–48.2%. UAE Estidama and Saudi Building Code achieved better saving depending on the climatic zone.Economic analysis show that these building codes are not always leading to economical solutions in some climates.
The number of countries with a national development plan has more than doubled, from about 62 in 2006 to 134 in 2018. This paper analyses the resurgence of national development planning, identifies the types and content of the plans, and their implications and interactions with the SDGs and the global development agenda.
Waste multilayer ceramic capacitors (MLCCs), containing BaTiO3, Ag, Pd, Ni, and Sn etc., and are a valuable secondary resource. The existing recycling process has great challenges when considering the environmentally friendly and efficient separation and recovery of resources. Contributing to SDGs 7, 9 and 12, this study demonstrates a simple and sustainable process to convert MLCCs into high value-added and efficient photocatalysts, which promises significant benefits for waste utilisation and environmental protection.

This piece provides insights into what has caused solar photovoltaic costs to fall so rapidly, such that in many parts of the world solar power plants are now more economical than coal- or gas-fired plants. This relates directly to SDG 7 (affordable & clean energy).
Contributing to SDG 13 (climate action), this rigorous study shows that renewable electricity systems could work equally well in both historical and future climates, despite changing weather patterns.
