  • Ammonia recovery from manure wastewater not only protects the aquatic ecosystem but also contributes to a sustainable nutrient cycle. Here the authors develop an electrochemical process enabling efficient ammonia recovery, with decentralized fertilizer and chemical production, from ammonia-rich manure wastewater.

  • Facilities that store the waste and tailings of mining operations pose a salient threat to biodiversity. Despite international consensus to mitigate mining impacts on local ecosystems, globally, nearly 10% of facilities are located within protected areas and another 20% can be found within 5 km of their boundaries.

  • Water consumption in line with natural water supply ensures sustainable and equitable access to freshwater resources worldwide. This study assesses whether renewable surface water is enough to meet people’s basic needs and, where it is not, estimates how much groundwater would be required.

  • Theories of change have been a staple of sustainability research, but how to connect such overarching concepts to actionable items can be a struggle. This study uses coastal wetlands to demonstrate a potential framework for integrating indicators of conservation enabling conditions into theories of change.

  • Gold mining has a substantial impact on the surrounding environment, especially in terms of mercury release and high energy consumption. Retorts have reduced the magnitude of mercury emissions in the Brazilian Tapajós River basin, but gold mining still releases 16,000 kg of CO2 equivalent per kilogram of gold.

  • Catalytic upcycling of waste plastics has multiple benefits from a sustainability perspective, but available processes struggle with chlorine-containing feedstocks. Here the authors propose a strategy capable to upcycle chlorine-containing plastic wastes to valuable chemicals.

  • Rural coastal communities depend on natural ecosystems, such as mangrove forests and wetlands, for protection against local sea level rise. Mangroves prove relatively resilient to sea level rise; however, landward shoreline retreat persists, forcing rural communities from coastal settlements.

  • The UN 2030 Agenda for Sustainable Development recognizes the need to transform governance for the world to develop sustainably. Using a mixed method approach, this study presents 13 principles for transformative ocean governance that can help turn ocean-use practices into more sustainable ones.

  • Heavy-duty vehicles are responsible for a substantial portion of road emissions from fossil-fuelled vehicles and cause harmful air pollution. Transitioning to electric heavy-duty vehicles would provide substantial health benefits, especially in Black and Hispanic/Latino urban neighbourhoods.

  • Coral reefs and related fish populations are under threat of extinction unless additional conservation measures are put in place. Focusing on 12 countries with diverse income and tropical reef proximity, this study analyses the willingness of the public to pay for global coral and reef fish conservation.

  • Bisphenol A (BPA) is an essential building block for manufacturing plastics, but its adverse health effects have become a major concern. Here the authors show a zeolite-catalysed synthetitic route to bio-renewable BPA alternatives that feature excellent safety and preserve efficacy of function.

  • Levees can obscure the public perception of flood risk, reflected in accelerated rates of development in floodplains relative to surrounding areas. Effective regulation and legislative measures can reverse this effect for more sustainable management.
