The present work provides an overview of technological measures to increase the self-sufficiency of wastewater treatment plants (WWTPs), in particular for the largely diffused activated sludge-based WWTP. The operation of WWTPs entails a huge amount of electricity. Thermal energy is also required for pre-heating the sludge and sometimes exsiccation of the digested sludge. On the other hand, the entering organic matter contained in the wastewater is a source of energy. Organic matter is recovered as sludge, which is digested in large stirred tanks (anaerobic digester) to produce biogas. The onsite availability of biogas represents a great opportunity to cover a significant share of WWTP electricity and thermal demands. Especially, biogas can be efficiently converted into electrical energy (and heat) via high temperature fuel cell generators. The final part of this work will report a case study based on the use of sewage biogas into a solid oxide fuel cell. However, the efficient biogas conversion in combined heat and power (CHP) devices is not sufficient. Self-sufficiency requires a combination of efficient biogas conversion, the maximization the yield of biogas from the organic substrate, and the minimization of the thermal duty connected to the preheating of the sludge feeding the anaerobic digester (generally achieved with pre-thickeners). Finally, the co-digestion of the organic fraction of municipal solid waste (OFMSW) into digesters treating sludge from WWTPs represent an additional opportunity for increasing the biogas production of existing WWTPs, thus helping the transition toward self-sufficient plants.

“…above 0.5 -1 MW (Lantz, 2012)). The adoption of SOFCs in WWTPs would have a dramatic impact on boosting the biogas conversion efficiencies in WWTPs as SOFCs can generate electricity with an efficiency in the interval 50 -62 % (Curletti et al, 2015).…”

“…Medium-scale fuel cells are also a promising option due to their high electrical efficiency and suitability for CHP applications. This latter technology, using solid oxide fuel cell (SOFC) technology ( (Leone, 2014); (Tjaden et al, 2014); (Curletti et al, 2015)) is the main prime mover of interest in this article due to the ability to generate electricity in the efficiency range of 50 -62 % (Curletti et al, 2015).…”

“…Adopting the technology assuring the highest energy valorization of these waste streams is an important challenge. In this context, Solid Oxide Fuel Cell (SOFC) systems seem to represent the best option for the energy recovery from biogas [32], [33]. Furthermore, looking at the biogas potential in EU, the most common anaerobic digestion plant size is in the sub-MW scale, which is exactly the size where the efficiency of SOFC-based systems outperforms one of the thermal plants with a value of around 20% points.…”

Urban districts should evolve towards a more sustainable infrastructure and greener energy carriers. The utmost challenge is the smart integration and control, within the existing infrastructure, of new information and energy technologies (such as sensors, appliances, electric and thermal power and storage devices) that are able to provide multi-services based on multi-actors and multi and interchangeable energy carriers. In recent years, the Municipality of Torino represents an experimental scenario, in which practical experiences in the below-areas have taken place through a number of projects: 1. energy efficiency in building; 2. smart energy grids management and smart metering; 3. biowaste-to-energy: mixed urban/industrial waste management with enhanced energy recovery from biogas. This work provides an overview and update on the most interesting initiatives of smart energy management in the urban context of Torino, with an analysis and quantification of the advantages gained in terms of energy and environmental efficiency.
