“…Given that this is a new technology, the data are based on the operation of the small pilot plant capable of treating 1.4 m 3 of water per day. The data for GAC have been sourced from Orica Watercare (2009) and the literature (Meier, 1997;Bayer et al, 2005;Muñoz, 2006). The background data for both systems are from the Ecoinvent V2.2 (Ecoinvent, 2010) and Gabi databases (PE International, 2011).…”

“…As shown in Table 3, two different datasets for GAC production are available (Bayer et al, 2005;Meier, 1997), which have been used in other studies, including Bonton et al (2012), Muñoz (2006) and Mery et al (2014). Considering that the data for GAC production in Bayer et al (2005) are more recent, they have been used for this study, while the older data from Meier (1997) are used in a sensitivity analysis later in the paper. LCI data on the reactivation of spent GAC are also available in various studies but the most detailed and complete inventories were found in Hutchinson (1975) and Meier (1997) as shown in Table 4.…”

“…As also stated previously, the data from Bayer et al (2005) and Hutchinson (1975) have been used in the main analysis (GAC-1 and GAC-2) in this study. To examine the effect on the results of these two different datasets, a sensitivity analysis has been carried out using a second dataset provided by Meier (1997).…”

“…Alternatively, the spent GAC can be regenerated thermally for reuse e this option is practiced widely as it is more economically viable than disposal (San Miguel et al, 2001). However, thermal regeneration is an energy intensive process often requiring transportation to off-site regeneration facilities and results in about a 10% loss of GAC in each regeneration cycle (Bayer et al, 2005;McKay, 1996). Furthermore, the reactivation can enlarge the pores in the activated carbon owing to the burn-off effects which can affect adversely its capacity to adsorb small organic molecules (Matilainen et al, 2006).…”

Several studies have also examined the environmental impacts associated with specific treatment technologies or processes to remove organic contaminants such as GAC, nanofiltration, membrane filtration (RomeroHernandez, 2005;Bayer et al, 2005;Muñoz et al, 2007Muñoz et al, , 2009Marín et al, 2011;Bonton et al, 2012;Manda et al, 2014). The current study is the first to assess the LCA impacts and economic costs of the Arvia process.…”

Comparing centralized and point‐of‐use treatments of per‐ and polyfluoroalkyl substances

Per‐ and polyfluoroalkyl substances (PFAS) chemicals are a growing threat to public health and safety. This study seeks to compare the life cycle environmental, economic, and human health performances of centralized and point‐of‐use (POU) systems used to upgrade existing drinking water treatment facilities for enhanced PFAS removal, using Merrimack, NH as a testbed. Out of all studied system upgrade scenarios, a POU scenario that combines granular activated carbon and ion exchange filters has the lowest environmental and human health impacts and relatively low economic impact. Despite all drinking water taps in the house being protected, the centralized scenario does not perform the best in terms of the health impacts because of its relatively low perfluorooctane sulfonate removal efficiency. This suggests a potential tradeoff between protecting the highest number of taps and achieving the highest removal efficiency at limited taps as two water treatment objectives.

From the most classic carbon materials (CMs) to the advanced ones, all of them integrate a promising catalyst set in terms of sustainability and energy efficiency for a greener future. Different synthetic strategies concerning to the catalytic synthesis of relevant N‐containing heterocycles are herein described to address the great potential of the referred catalysts flying over what has been done and all that remains to be done. Current trends in this field involve structure‐activity relationships establishment also considering the reaction mechanisms understanding and the identification of active catalytic sites, as function of both experimental datasets, emphasizing on operando characterization techniques, and theoretical studies which will significantly contribute to the design of custom‐made catalysts as a new horizon.
