This Special Issue, bringing together articles from Science of the Total Environment; Renewable and Sustainable Energy Reviews; Ecological Modelling, and Resources; Conservation and Recycling, highlights the increasing understanding that major systems servicing human well-being, food, energy and water (FEW) systems are inextricably connected, and any attempt to address one dimension in isolation of the others will lead to unexpected, undesired, and far from optimal consequences. Considering these three systems holistically as the Food-Energy-Water Nexus directly considers Sustainable Development Goals 2 (zero hunger), 6 (clean water and sanitation), 7 (affordable and clean energy), 9 (industry, innovation and infrastructure), and 12 (responsible consumption and production).
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.
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 book chapter addresses goals 12, 7, 11 and 15 by looking at the environmental and economic impact of the utilization of biomass resources.

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.

A total of 1.8–4.1 billion people are potentially exposed to heat stress due to lack of access to cooling energy systems. This study develops a comprehensive measure of energy access by introducing the dimension of space cooling. This research has direct implications for human health and wellbeing (SDG 3), and interacts with SDGs 7 (affordable and clean energy) and 11 (sustainable cities and communities).
