“…Ref. [25] addressed the optimization of an EC that comprised a wastewater treatment plant, a hotel complex that included restaurants, and the energy demand of administrative buildings in the southeast of Romania, near the sea. As a local source of electricity generation, the biogas that was obtained from the treatment water of a wastewater treatment plant (WWTP) was used as the fuel for a combustion engine (50 kW) and a PV plant (100 kWp).…”

In recent years, there has been a growing interest in the study of energy communities. This new definition refers to a community sharing energy resources of different types to meet its needs and reduce the associated costs. Optimization is one of the most widely used techniques for scheduling the operation of an energy community. In this study, we extensively reviewed the mathematical models used depending on the objectives and constraints considered. The models were also classified according to whether they address uncertainty and the inclusion of flexibility constraints. The main contribution of this study is the analysis of the most recent research on the mathematical formulation of optimization models for optimal scheduling of resources in energy communities. The results show that the most commonly used objectives are profit maximization and cost minimization. Additionally, in almost all cases, photovoltaic generation is one of the main energy sources. Electricity prices, renewable generation, and energy demand are sources of uncertainty that have been modeled using stochastic and robust optimization. Flexibility services using demand response are often modeled using interruptible loads and shiftable loads. There is still considerable room for further research on the distribution of benefits among the participants of the energy community and the provision of flexibility services to the electricity grid.

“…The MBT facility of Galati city will have a sorting line and anaerobic digestion plant with a co-generator to produce electricity [86]. Another innovative solution is the use of biogas derived from sewage sludge (urban WWTP), combined with photovoltaic installation to feed the tourism sector with clean energy, such as in seaside hotels [87]. Clean energy sources, responsible water consumption, source-separation of waste, composting, and organic farming are all steps to provide sustainable rural agri-tourism development in Eastern Romania.…”

This paper reveals the linear economy contribution to resource degradation and environmental pollution in eastern Romania that could further feed environmental crimes and conflicts, such as in the Pungesti shale gas case. Preservation of material and water resources in the region is required through various circular mechanisms under a cross-sectoral approach including solid waste as a material resource for industry and agriculture; wastewater treatment and water reuse; composting and organic agriculture; and using renewables. Six non-conflictual sustainable alternative routes related to circular economy mechanisms, water preservation, and to the clean energy transition are proposed in this paper, which are further examined through key statistics and indicators, current best practices, and local development pathways in both urban and rural communities.
