To achieve SDG 13 (Climate action), urban areas must reduce energy use and transition to greener energy sources. This One Earth Research Article shows how innovative photovoltaic windows could contribute, especially in buildings with lots of windows. The work also supports supports sustainable industrialization and innovation (SDG 9) and affordable clean energy (SDG 7).

This article supports SDG 6, 3, 9 by exploring the diversity and ecology of freshwater diatom as bioindicators of 6 major freshwater ponds of Kanyakumari district, Tamilnadu

Biofilms are a major challenge for the food industry, due to their ability to contaminate surfaces. Foam flow cleaning successfully removed a significant part of one-day biofilms grown on stainless steel surfaces. Life cycle analyses showed that the foam flow process reduces all environmental impacts, mainly due to the reduction in water and energy consumption, which is a crucial contemporary issue.

This Editorial highlights 17 contributions from outstanding women researchers in chemical engineering supporting SDG 5 (Gender equality) as well as SDG 9 (Industry, innovation and infrastructure).

The roadmapping exercise looking at the quantitative modelling of cleaning and decontamination held in 2021 identified a number of factors as common to cleaning and decontamination across many sectors. Tackling new challenges such as the food-water-energy nexus and the wider sustainability agenda means that Sinner’s circle, often used to frame discussions of cleaning in the food sector, needs an upgrade.

Ultrafiltration with ceramic membranes of olive oil washing wastewater has been demonstrated to be an interesting alternative as a previous step for the recovery of phenolic compounds, which have outstanding antioxidant characteristics. In this way, the treatment of these wastewaters should be based on reusing water and, at the same time, on recovering valuable compounds.

This Comment supports SDG 3 and 9 by describing an ongoing study in rural Guatemala to assess interventions to reduce plastic burning in household fires, and how plastic burning is affecting air quality

A system transition is required to reach greater circularity in the production and consumption of plastics and the achievement of SDG12. This paper has addressed a key gap in the literature, related to the role that data-information-knowledge play in hindering progress towards that transition.

This article presented a comprehensive life cycle assessment (LCA) study comparing alternative medical-grade and protective-device-grade mask reuse options to the conventional single-use of surgical and FFP3 masks, respectively. The study focuses on the UK, but the results and conclusions are applicable to other healthcare settings.

Strategies to decarbonize the hard to abate iron and steel sector.
