  • Biofuels and carbon footprint

    Europe’s use of biofuels to fuel its vehicles risks driving land grabs and deforestation, increasing food prices, exacerbating poverty and hunger, and accelerating climate change. We are seriously concerned that the Commission has not yet taken action to ensure that Europe’s green transport policy discourages those biofuels that cause higher greenhouse gas emissions than fossil ...

  • Blue and grey water footprint of textile industry in China

    Water footprint (WF) is a newly developed idea that indicates impacts of freshwater appropriation and wastewater discharge. The textile industry is one of the oldest, longest and most complicated industrial chains in the world's manufacturing industries. However, the textile industry is also water intensive. In this paper, we applied a bottom-up approach to estimate the direct blue water ...

  • Temporal and spatial changes of water footprint of maize production in Jilin Province

    Quantitation of the green, blue and grey water footprints (WFs) of crop production can distinguish the water types and amount in crop production, as well as the degree of freshwater pollution. This paper calculates the WF of maize production and assesses the temporal variability and spatial distribution of WFs in different types of rainfall years over Jilin Province from 1998 to 2012. The ...

  • Water footprint of Xiamen city from production and consumption perspectives (2001–2012)

    Providing a comprehensive insight, water footprint (WF) is widely used to analyze and address water-use issues. In this study, a hybrid of bottom-up and top-down methods is applied to calculate, from production and consumption perspectives, the WF for Xiamen city from 2001 to 2012. Results show that the average production WF of Xiamen was 881.75 Mm3/year and remained relatively stable during ...

  • Past and future trends in grey water footprints of anthropogenic nitrogen and phosphorus inputs to major world rivers

    The grey water footprint (GWF) is an indicator of aquatic pollution. We calculate past and future trends in GWFs related to anthropogenic nitrogen (N) and phosphorus (P) inputs into major rivers around the world. GWFs were calculated from past, current and future nutrient loads in river basins using the Global NEWS model. We present water pollution levels (WPLs), deduced from GWFs for more than ...

  • Chemical footprint: A methodological framework for bridging life cycle assessment and planetary boundaries for chemical pollution

    The development and use of footprint methodologies for environmental assessment are increasingly important for both the scientific and political communities. Starting from the ecological footprint, developed at the beginning of the 90s, several other footprints were defined, e.g. carbon and water footprint. These footprints ‐ even though based on different meaning of “footprint” ‐ integrate ...

  • Upgrading Water Injection Pumps

    Water injection pumps that are used in oil exploration typically face extreme abrasion, chemical attack, and cavitation erosion in their daily operation. The injected water is frequently loaded with abrasive particles, such as quartz sand, which quickly erode conventional pump surfaces. Sulzer’s service teams offer solutions to increase the lifetime and the performance of water injection ...

  • Accelerating the move to a low water economy

    Carry out even a small amount of research into global water scarcity and the statistics can be unnerving. The UN estimates that 2.7 billion people will face water scarcity by 2025, and with climate change accelerating higher salinity levels in a number of regions, water scarcity is now more of a threat than ever. The future for water availability looks very uncertain, but attempts are now being ...

  • Climate change mitigation by recovery of energy from the water cycle: a new challenge for water management

    Waternet is responsible for drinking water treatment and distribution, wastewater collection and treatment, and surface water management and control (quality and quantity) in and around Amsterdam. Waternet has the ambition to operate climate neutral in 2020. To realise this ambition, measures are required to compensate for the emission of 53,000 ton CO2-eq/year. Energy recovery from the water ...

  • Energy analysis of reclaimed water application for irrigation in arid and semi-arid regions

    Freshwater availability is the major constraint to agriculture in arid and semi-arid regions. The groundwater and energy conservation of applying reclaimed water for irrigation was analysed, using Southern California as the spatial domain for model testing. An extensive compilation of the most recent publicly available datasets was used to calculate the energy intensity for each water supply ...

  • Using FTIR spectroscopy to measure hydrocarbon pollution in water

    According to the World Health Organization (WHO) and UNICEF’s 2015 Progress on Sanitation and Drinking Water report almost 700 million people around the world don’t have access to clean drinking water [1]. Poor water quality is beginning to return to the developed world too. The strain of population growth, intensified agricultural practices and continued industrial expansion have are ...
