Imagine turning the vast, salty oceans into an endless supply of clean water for drinking and industries alike. That’s the reality of seawater reverse osmosis desalination. It’s not a far-off dream or a scene from a sci-fi movie. It’s happening right now, all over the world. Seawater reverse osmosis desalination is a game-changer in the fight against water scarcity. It’s ...
Most granular measurements rely on life-cycle assessments (LCAs)—product-specific studies that track emissions all the way from raw materials to final disposal. ...
The German environmental protection agency, Umweltbundesamt, commissioned Sphera to conduct a Life Cycle Assessment (LCA) study of the electricity generation from wind turbines in Germany. The study aimed to evaluate and update the existing body of LCA work around electricity generation from wind turbines, taking ...
Ultra-processed foods are now simply part of the flavour of modern life. These foods are convenient, affordable, highly profitable, strongly flavoured, aggressively marketed – and on sale in supermarkets ...
A research conducted in Southern European wineries compared the conventional and natural wastewater treatment technologies via life cycle assessment and carbon footprint studies. The research group utilized Gasmet’s portable FTIR gas analyzer DX4015 for monitoring the GHGs. The present study can be seen as ...
This is currently becoming more and more important and a new study on life cycle assessment confirms that e-mobility has great future potential. "Cradle-to-Grave" analysis is currently being discussed in the automotive industry with regard to the eco-balance. This refers to the so-called "life ...

A life cycle assessment (LCA) approach was used in the assessment of environmental impacts of some polishing units for reuse of wastewater treatment plant effluents in agricultural irrigation. These alternative polishing units were assessed: (1) microfiltration and ultraviolet (UV) disinfection, (2) cartridge ...
In the present study, a life cycle assessment (LCA) approach was used to analyse the environmental impacts associated with the construction and operational phases of an integrated fixed-film activated sludge (IFAS) reactor treating municipal wastewater. This study was conducted within the boundaries of a ...
Covering the stored SS, treating it with urea and choosing the correct time for land application all have the potential to reduce emissions from the system. Using life cycle assessment (LCA), this study compares storage and land application options of SS in terms of global warming potential (GWP), acidification potential, ...
Very often the fate of chemicals after use is to be sent to municipal wastewater treatment plants (WWTPs), where they are subject to degradation. In many life cycle assessment (LCA) studies we need to account for the environmental impacts caused by the disposal of chemical substances down the drain, however existing LCA models ...
The results were intended to develop an inventory of available methods and models used to assess human and environmental exposure to manufactured nanomaterials. The survey gathered information on a variety of types of methods and models, including those used to set priorities, screen nanomaterials, develop detailed assessments of exposure, and other types of ...
This article introduces the special series “LCA in Market Research and Policy: Harmonization beyond standardization,” which was generated from the 19th SETAC Life Cycle Assessment (LCA) Case Study Symposium held November 2013, in Rome, Italy. This collection of invited articles reflects the purpose of symposium and focuses on ...
As an alternative to high-pressure or double-membrane systems, hybrid schemes consisting of a disinfection/filtration step prior to aquifer recharge were assessed in this study regarding their environmental footprint and energy efficiency. A simplified life-cycle assessment (LCA) for a hypothetical case ...
Photovoltaic (PV) system has been quoted for wide range of green house gas (GHG) emissions through life cycle assessment (LCA) studies. There are a variety of solar cell materials available, which vary in conversion efficiency and emission of CO 2 . ...
One of the major drawbacks of wind energy, however, is its variability due to the stochastic nature of wind, thus, supplemental energy generation or storage technologies are required. In this study, a life cycle assessment approach is applied to estimate the environmental impacts of potential supplemental energy generation ...
By carrying out a life cycle assessment (LCA), the case study greenway was found to embody 67.6 tCO 2 e/km; the carbon savings of shifting one passenger kilometre travelled (PKT) from driving a car to cycling were found to average 134 gCO 2 e. In the case study, a shift of 115 commuters per ...
An organization seeking to provide an EPD for a product needs first to conduct a life cycle assessment, or LCA, of that product or material and then, in conjunction with an independent organization such as ASTM International, must develop an EPD. ...
This work reviews and performs a meta‐analysis of the recent Life Cycle Assessment and flow analyses studies palm oil biodiesel. The best available data and information are extracted, summarized and discussed. ...
This study investigates the cumulative energy demand (CED) of different systems for the management of urban wastewater, following the methodology of Life Cycle Assessment. In a hypothetical case study for an urban area (5,000 inhabitants), all relevant processes for wastewater collection and treatment and the ...
Since the emergence of life cycle assessment (LCA), many studies have focused on the integration of uncertainties. Nevertheless, data quality assessment and statistical approaches are not yet widely used to quantify uncertainty, and when used, methodologies are neither uniform nor rigorous. ...
