“…taking into account for the different functions of the plant). Although benchmarking methods based on multiple KPIs have been discussed, such as by Fraia et al [20], some sort of weighting between different KPIs would be necessary. Otherwise, it can be difficult to interpret the results of different indicators, since trade-offs exist for WWTPs at different stages of their lifecycles.…”

This paper describes the first methodology specifically tailored to estimate energy efficiency at wastewater treatment plants (WWTPs). Inspired by the cycle of continuous improvement, the method i) precisely defines the concept of energy efficiency in WWTPs, ii) proposes systematic and comparable ways to measure it, and iii) allows benchmarking and diagnosing energy hotspots. The methodology delivers an aggregated measure of the WWTP energy efficiency defined as the Water Treatment Energy Index, a single energy label that uses universally known illustrations enabling wide communication of standardized information on the WWTP energy status. The accuracy, reproducibility and generality of the methodology were validated by a widespread energy benchmarking method, and a case study is presented to show its capabilities. By promoting dialogue towards the

“…The overall system performance can be enhanced for high gasification temperatures and low air equivalent ratios. Other papers on the efficient waste management regard the definition of a primary energy return index, used for comparing different municipal solid waste management scenarios [49]; the coupling of renewable energy source in a wastewater treatment plant consisted of conventional activated sludge systems [50]; and a novel methodology applied to evaluate urban wastewater treatment plants in terms of energy efficiency [51,52]. This topic was dealt with comprehensively in previous SDEWES SIs focusing on different aspects, namely: the influence of urban form on the performance of road pavement solar collector system [53]; the energy management in a smart municipal energy grid including combined heat and power plants, solar photovoltaic and wind technologies [54]; the analysis of the future energy scenarios on the Danish municipality of Helsingør to obtain a cost-optimal combination between individual heating, district heating and heat savings [55]; a study on the management of dust to ensure that urban environment and industry can coexist in a sustainable and beneficial manner [56]; the adoption, in urban water distribution systems, of energy storage systems to meet the water demand [57]; the evaluation of carbon emissions in highly polluted European cities [58]; the replacement of bituminous roofs as green roofs to make cities more 'future proof' and resilient [59]; the integration of the renewable energy resources to enhance the regional energy efficiency and sustainability [60]; and many other papers concerning the analysis of energy efficiency targets of the member countries of the EU [61][62][63].…”

Several countries have recently realized that the present development paradigm is not sustainable from an environmental and energy point of view. The growing awareness of the population regarding environmental issues is pushing governments worldwide more and more to promote policies aiming at limiting harmful effects of human development. In particular, the rapid increase of the global temperature, especially in the polar regions, and the management of human wastes, mainly plastic in seas, are some of the main points to be addressed by these novel policies. Several actions must be implemented in order to limit such issues. Unfortunately, the recent COP 24 Conference was not successful, but hopefully an agreement will be established in 2020 at the COP 26 Conference. The effort performed by policymakers must be mandatorily supported by the scientific community. In this framework, this paper aims at showing that countries worldwide are trying to negotiate an agreement to increase energy efficiency and reduce greenhouse gas (GHG) emissions. In addition, in this paper all the researchers reported can provide quantitative measures of the actions to be implemented in order to address a sustainable and efficient use of energy. Here, innovations in terms of novel efficient and environmentally friendly technologies mainly based on renewable energy sources have been also investigated. The study also highlights different sectors that have been involved for this aim, such as energy conversion systems, urban areas, mobility, sustainability, water management, social aspects, etc. In this framework, specific conferences are periodically organized in order to provide a forum for discussion regarding these topics. In this area the Sustainable Development of Energy, Water and Environment Systems (SDEWES) conference is the most ordinary conference. The 13th Sustainable Development of Energy, Water and Environment Systems Conference was held in Palermo, Italy in 2018. The current Special Issue of Energies, precisely dedicated to the 13th SDEWES Conference, is based on three main topics: energy policy and energy efficiency in urban areas, energy efficiency in industry and biomass and other miscellaneous energy systems.

“…This is primarily due to the high requirements applied to the treatment of wastewater from petroleum products, as well as the complexity of the composition of incoming effluents. New aeration devices, physical methods of intensification of contact of gas and solid phases speak in favour of flotation method with its simplicity and efficiency that can become the main in the treatment of oily wastewater [3,4].…”

The article focuses on factors that might be crucial if an energy efficiency in the field of water supply and wastewater treatment is considered. There are most common drawbacks in maintenance of water supply and wastewater system described as well as the directions on the improvement of situation. The main directions of technological energy saving is the use of energy efficient technologies; energy efficient engineering solutions, and methods and equipment for regulating the operation of facilities and equipment.
