Abstract Due to global water scarcity, the use of reclaimed wastewater for crop irrigation is required; however, if the wastewater treatment is inadequate, it can be a source of environmental pollution. In order to improve wastewater reclamation, advanced oxidation processes (AOPs) have been tested. At full scale, ozonation is one such process that effectively removes micropollutants, despite its high-energy consumption. At pilot scale, other technologies such as the solar photo-Fenton process a...

Purpose So far, land occupation impact assessment models in life-cycle assessment have predominantly considered biodiversity, ecosystem quality and ecosystem services. However, in a manner similar to water consumption, land occupation has the potential to impact food production and thereby human health. In this study, the impact pathway linking land occupation and protein-energy malnutrition was modelled, establishing a new set of regionalised characterisation factors which were applied in a cas...

Abstract Supply chains become increasingly globalized. Multi-regional input-output databases contain all the information to assess impacts along the value chain, but standard calculation routines to track the impacts of any sector along the global upstream and downstream value chain are missing. Mapping the impacts of materials has been a particular challenge owing to difficulties with double-counting. This is attributed to the strong intertwining of the material supply chain meaning that differ...

Purpose Regionalized life cycle impact assessment (LCIA) has rapidly developed in the past decade, though its widespread application, robustness, and validity still face multiple challenges. Under the umbrella of UNEP/SETAC Life Cycle Initiative, a dedicated cross-cutting working group on regionalized LCIA aims to provide an overview of the status of regionalization in LCIA methods. We give guidance and recommendations to harmonize and support regionalization in LCIA for developers of LCIA metho...

Fresh water is a renewable yet limited natural resource. While abundant in some areas, fresh water is scarce in others where its consumption in agriculture leads to negative impacts on humanity, ecosystems and biodiversity. International trade in water intensive products can help to reduce water stress or may increase water consumption in water stressed regions.

Purpose While many examples have shown unsustainable use of freshwater resources, existing LCIA methods for water use do not comprehensively address impacts to natural resources for future generations. This framework aims to (1) define freshwater resource as an item to protect within the Area of Protection (AoP) natural resources, (2) identify relevant impact pathways affecting freshwater resources, and (3) outline methodological choices for impact characterization model development.

Biofuels play a critical role in the Paris Agreement to help achieve climate change mitigation targets. However, a significant increase in production of biofuels might potentially be realized at the expense of overusing natural resources, particularly land and water. Understanding the tradeoffs between the impacts on land and water arises as a critical issue in the development of biofuels. This energy-water-land nexus might be particularly important for Brazil, which currently is the world's sec...
