Mohamed H. Ibrahim discusses how electrochemical membrane reactors can be used for magnesium waste valorization.

Most manufactured products contain materials produced with carbon from fossil feedstocks. Econic Technologies has developed a process for replacing fossil feedstocks used to produce polymers with captured carbon from waste carbon dioxide.

Metal–CO2 batteries offer the dual benefits of energy storage and carbon utilization, but their commercial viability is limited by drawbacks in performance, cost and safety. This Review discusses barriers to the development and commercialization of aqueous and non-aqueous metal–CO2 batteries and how to overcome them.

Wind turbine retirement will result in large end-of-life material flows that must be managed. This Review discusses material reuse and recycling options for composites, steel, rare-earth elements and concrete.

Floating offshore wind farms can harvest the steady winds found at sea in locations where the seabed is too deep for fixed-bottom wind turbines. This Perspective explores the technical, industrial and social implications of deploying floating offshore wind on a commercial scale.

Multi-junction solar cells can provide a way to increase the efficiency of solar cells beyond the theoretical efficiency limits of single-junction devices. This Review explores the design and performance of multi-junction devices that use perovskite materials for the two wide bandgap middle and top layers.

Life cycle assessment (LCA) can measure the environmental impact of products and technologies, but it faces challenges in data quality and system interoperability. This Review examines the need for standardized methodologies, improved transparency, open-source tools, and the integration of artificial intelligence and blockchain to develop global LCA data systems.
