“…CML (Guinée et al, 2001), ReCiPe (Goedkoop et al, 2009), Impact 2002+ (Humbert et al, 2012) and TRACI (Bare, 2011)) can affect their results in impacts that are site-dependant or when normalization or weighting factors are considered (e.g. Palomares-Rodríguez et al, 2017;Lam et al, 2015). Accordingly, Zhao et al (2017) compared the results of the implementation of bioaugmentation in a constructed wetland using a site-generic method like CML (Guinée et al, 2001) and e-Balance (IKE, 2014), an impact methodology designed specifically for China context.…”

Within developing countries, wastewater treatment (WWT) has improved in recent years in but remains a high priority sustainability challenge. Accordingly, life cycle assessment (LCA) studies have recently started to analyse the environmental impacts of WWT technologies on the specific context of less developed countries, mainly in China and India. This work presents a comprehensive review of this knowledge with the aim of critically analysing the main conclusions, gaps and challenges for future WWT-related LCAs in developing countries. The most commonly assessed technologies in the 43 reviewed articles are different variations of activated sludge and extensive treatments applied in decentralized systems; however, studies focused on advanced technologies or new sources of pollution (e.g. micropollutants) are still lacking. Goal and system boundaries are normally clearly defined, but significant stages for some technologies such as the construction and sludge management are frequently not included and functional units should be defined accordingly to specific conditions in developing countries. At the inventory level, a more concise description of sources and technical parameters would greatly improve the quality of the LCAs along with accountability of direct greenhouse gas emissions. Eutrophication and global warming are the two

“…Second, the global energy crisis and environmental pollution have recently increased as a result of the use of fossil fuels. To address this, major efforts are underway to develop alternative methods of wastewater treatment and energy production that are economical and do not pollute (Du et al, ; Jafary et al, ; Palomares‐Rodríguez et al, ).…”

This work assessed the performance of a single-chamber microbial fuel cell (MFC) with various substrates. Primary settled domestic wastewaters were used to simulate wastewaters of high biodegradability; while phenol-based wastewaters and benzene-based wastewaters were used to simulate wastewaters of low biodegradability. Experiments were performed at initial pH values of 6, 7 and 8. The maximum voltage production, power density and removal of substrate were obtained using primary settled domestic wastewater, whereas the lowest values were obtained using phenol-based wastewater. The maximum chemical oxygen demand removal efficiency, phenol removal efficiency and benzene removal efficiency were 80.8, 63.3 and 77.8%, respectively. The performance of the MFC was enhanced by increasing the influent pH. The lowest coulombic efficiencies were obtained from phenol-based wastewater and benzene-based wastewater, which indicated that electrogenic bacteria were not the primary microorganisms responsible for the biodegradation of low biodegradable wastewater.

“…Palomares-Rodríguez et al (2017) provided economic and energy demand justification for leveraging a combination of aerobic and anaerobic treatment that would reduce energy requirement by 76% and environmental impact by 30% [54]. Sequencing batch reactors have also been studied to remove COD and nitrogen to operate between nitrification and denitrification, aerobic and anaerobic methods [74,75].…”

Commercialization in the meat-processing industry has emerged as one of the major agrobusiness challenges due to the large volume of wastewater produced during slaughtering and cleaning of slaughtering facilities. Slaughterhouse wastewater (SWW) contains proteins, fats, high organic contents, microbes, and other emerging pollutants (pharmaceutical and veterinary residues). It is important to first characterize the wastewater so that adequate treatment techniques can be employed so that discharge of this wastewater does not negatively impact the environment. Conventional characterization bulk parameters of slaughterhouse wastewater include pH, color, turbidity, biochemical oxygen demand (BOD), chemical oxygen demand (COD), total organic carbon (TOC), total suspended solids (TSS), total nitrogen (TN), total phosphorus (TP), and coliform counts. Characterization studies conducted have revealed the effects of the pollutants on microbial activity of SWW through identification of toxicity of antibiotic-resistant strains of bacteria. Due to the high-strength characteristics and complex recalcitrant pollutants, treatment techniques through combined processes such as anaerobic digestion coupled with advanced oxidation process were found to be more effective than stand-alone methods. Hence, there is need to explore and evaluate innovative treatments and techniques to provide a comprehensive summary of processes that can reduce the toxicity of slaughterhouse wastewater to the environment. This work presents a review of recent studies on the characterization of SWW, innovative treatments and technologies, and critical assessment for future research.
