Themed collection UN Sustainable Development Goal 15: Life on Land

Safe-and-sustainable-by-design (SSbD) is a pre-market approach that integrates innovation with safety and sustainability along the entire life cycle.

Phytomining, the extraction of valuable metals from soil or waste substrates using plants, has gained increasing attention as a sustainable and economically viable alternative to conventional mining practices.

Complex polysaccharide substrates can serve as direct feedstocks for PHA biosynthesis, potentially eliminating the need for extra processing steps and significantly lowering production costs for sustainable plastics.

This study demonstrates SLA 3D printing of Li-ion battery anodes using recycled solar cell waste, achieving 400 mA h g⁻¹ capacity with 89% retention after 200 cycles. This sustainable approach surpasses graphite anodes and supports circular economy.

Co-pyrolysis of biomass and plastics is essential to improve the quality and yield of pyrolytic products, optimise energy recovery, and mitigate plastic waste, providing a sustainable approach to waste valorisation.

A process combining brine-electrolysis and photolysis is proposed for CH₄ and CO₂ removal from the troposphere. Further developments to meet applicable technology constraints in overall negative emission and economic viability are discussed.

Non-isocyanate polyurethane nanocomposites from soybean oil and TiO₂ exhibit improved thermal stability, mechanical strength, hydrophobicity, and antimicrobial properties, highlighting eco-friendly material innovation.

We conduct a harmonized lifecycle greenhouse gas assessment to compare the carbon removal efficiency and total energy required for twelve engineered carbon removal technologies.
