Latin America's construction industry is undergoing a profound transformation as sustainability standards tighten and green building certification becomes increasingly important. From LEED-certified office towers in São Paulo to EDGE-rated affordable housing in Mexico City, developers are seeking construction materials with verified environmental credentials. This shift creates unprecedented ...
The water footprint is an essential tool to understand the impacts human have on this essential yet finite resource. Water has become increasingly vulnerable as a result of climate change, population growth and growing pressure on this resource. In this context of global scarcity, there is an urgent need to calculate the water footprint as it is a tool that enables us to understand where, when ...

The holistic perspective applied to evaluation of modern WWTPs, including not only effluent quality but also resource efficiency and recovery, global environmental impact and operational cost calls for assessment methods including both on- and off-site effects. In this study, a method combining dynamic process models – including greenhouse gas ...
Bilec, an associate professor of civil and environmental engineering at the University of Pittsburgh and deputy director of the Mascaro Center for Sustainable Innovation, explained: As water becomes more of a precious resource around the globe, there is a greater focus on developing new methods of water efficiency and water conservation. […] We’ve worked closely ...
This paper presents a comparison of two very different options for removal of undesirable microorganisms and airborne pollutants from the indoor environment of hospitals, schools, homes and other enclosed spaces using air purifiers and photocatalytic coatings based on nano titanium dioxide (TiO2). Both products were assessed by Life Cycle ...
This paper conducts a comparative assessment of the environmental impacts of three methods of treating primary clarifier effluent in wastewater treatment plants (WWTPs) through life cycle assessment methodology. The three technologies, activated sludge (AS), high rate anaerobic-aerobic digestion (HRAAD), and ...
Anaerobic digestion (AD) is being established as a standard technology to recover some of the energy contained in the sludge in wastewater treatment plants (WWTPs) as biogas, allowing an economy in electricity and heating and a decrease in climate gas emission. The purpose of this study was to quantify the contributions to the total environmental impact of the plant using life cycle ...
The ongoing transition of the German electricity supply toward a higher share of renewable and sustainable energy sources, called Energiewende in German, has led to dynamic changes in the environmental impact of electricity over the last few years. Prominent scenario studies predict that comparable dynamics will continue in the coming decades, which will further improve the environmental ...
Biogas produced in municipal and industrial wastewater treatment facilities (BWWF) is a resource wasted in several socio-economic contexts. BWWF-based projects are compared against energy projects using conventional electricity or natural gas (NG), following strict economic considerations that usually tip the balance in favour of conventional energy supply. This is because the economic gain ...
In this regard, the Intergovernmental Panel on Climate Change (IPCC) 2007 GWP 100a methodology is utilised along with the method of the life cycle assessment. While the total average GWP value is 1,629 kg carbon dioxide equivalent (CO 2 e) per landing and takeoff (LTO), the total domestic flight-caused GWP value was calculated ...
Energy consumption and the climate–change impact (i.e., carbon footprint) of a typical Finnish broiler chicken fillet product were studied using a supply–chain integrated life cycle assessment method. All essential production stages from parent stock and production of farming inputs to product distribution and sales ...
Many organisations are seeking to adapt the life cycle assessment (LCA) method to estimate impact during the design stage and guide the development of sustainable products. ...
The 3-year pilot phase will start this autumn after a first call for volunteers closing on July 26th and is aimed at testing the implementation of sector specific rules based on Life Cycle Assessment thinking. The Recommendation published in April 2013 (1) presents methodologies for assessing the environmental footprint of ...

Waternet, the water cycle company of Amsterdam and surrounding areas, uses the life cycle assessment (LCA) method to evaluate the environmental impact of investment decisions and to determine the potential reduction of direct and indirect greenhouse gas (GHG) emissions of different alternatives. ...
Pharmaceuticals are normally barely removed by conventional wastewater treatments. Advanced technologies as a post-treatment, could prevent these pollutants reaching the environment and could be included in a centralized treatment plant or, alternatively, at the primary point source, e.g. hospitals. In this study, the environmental impacts of different options, as a function of several advanced ...
This paper compares the environmental impact including carbon footprint for these two approaches using the life cycle assessment (LCA) method, and provides a holistic view of how CSO is to be treated considering technical, economic and environmental issues. ...
To help dishwasher manufacturers to follow the EUP directive well in China, the environmental impact of the dishwasher in the whole life cycle is systematically assessed based on CML method, and the environmental impact caused by detergent is not included. ...
Carbon labeling is likely to be a powerful tool for informing consumers about the climate impacts of their purchasing decisions, but generating and interpreting the data for an accurate label is not without its challenges. Enhesa’s August 2011 webinar, attended by over 200 EHS professionals, explored the potential effect of carbon labeling throughout the entire supply chain and ...
Methodology for including specific biological effects and pathogen aspects into LCA As described in deliverable 4.1 (Larsen et al. 2007) NEPTUNE is using two main types of life cycle impact assessment (LCIA) methodologies when doing LCA studies on the waste water treatment technologies included. The basic methodology is the well known existing EDIP97 methodology (Wenzel et al. 1997, Hauschild ...
The environmental sustainability of tourism has been increasingly appearing in Local Agenda 21 and in the development policies of many countries. Although several studies have focused on sustainable tourism, only a few of them are based on life cycle assessment (LCA), the main methodology to assess environmental issues from a life cycle perspective. In order to gain a better understanding of the ...
