Themed collection UN Sustainable Development Goal 6: Clean water and sanitation

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

Chemistry should adopt material stewardship as a central mission in fulfilling its vital role in sustainability for people and planet.

This paper reviews the research on the conversion of nitroaromatics to aminoaromatics through catalysis.

Phosphorus recovery from animal manures by pyrolysis can effectively close the agricultural phosphorus cycle.

Incorporation of nanoparticles into the membrane matrix plays a pivotal role in water purification and treatment.

Increased human activity due to the ever-increasing global population has necessitated the urgent need for a sustainable environment, food, and energy.

Biochar offers a sustainable use of cannabis residues. Low temperature biochar can be used for contaminant adsorption and in soil amendment, and high temperature biochar as an electrode material in electrochemical and bioelectrochemical applications.

Microplastics are present in nearly all environments.

Cellulose acetate (CA) membranes incorporated with amino acids (AAs) and ionic liquids (ILs) fabricated using phase inversion technique have been proven to be efficient and effective for nanofiltration to treat heavy metal ion solutions.

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.

The environmental persistence of reactive blue 19 dye poses a significant challenge, driving the urgent need for efficient removal technologies to protect water quality.

Electrodes for supercapacitors were developed from activated carbon (GAC) derived from glutinous rice husk (GRH).

Solvent usage is one of the most critical factors for the carbon footprint of the chemical and pharmaceutical industries, with profound consequences of an undesirable or sub-optimal selection.

This study employs Life Cycle Assessment (LCA) to evaluate the environmental impacts of wastewater treatment systems in industrial zones of Vietnam.

A green method using liquid nitrogen produced gelatin–lignin beads with a Pb(II) adsorption capacity of 155 mg g⁻¹, 96% removal efficiency, and stability over 10 cycles, offering a sustainable solution for water treatment.

Zeolitic imidazolate framework improved vanadium ferrite (VFe₂O₄@_monoZIF-8) was prepared to purify a ciprofloxacin (CP), ampicillin (AP), and erythromycin (EY) contaminated water system via a visible light driven photocatalytic process.
