“…Also in this case, the authorization pathway suffers from the aggregation of heavy metals in the limit values to be complied with: Being a proposal of plant, it was not possible to know the speciation of metals inside these two categories. In this case study, the speciation was taken from a report of an Italian Region on the monitoring of emissions from modern incinerators [16]. From the average values of the sampling of each metal the fractionation of heavy metals was obtained for the two categories ( Table 5).…”

The European Union regulation for emissions from waste incinerators had a significant evolution in the last 20 years. That allowed reaching a clear improvement in the environmental performances of the plants, synchronized with specific requests of compliance of the more and more stringent limits set at regulatory level. Today the main questions for the sector in Europe seem mostly related to the role of waste to energy plants in a scenario of circular economy and to the role of those plants in the generation of energy only in part renewable. It seems that the topic of the local environmental and health impact has become out to date in European Union. In spite of that, a big question remains on the suitability of the present regulation for the future of the sector, including co-incineration by the use of Secondary Recovered Fuel from waste as substitute of coal in cement works. The present article analyzes an aspect that should be a priority higher than the concept of circular economy and energy generation. Indeed, a question remains on the criticalities that could be present in the European Union for underestimation of the role of heavy metals, in spite of the evolution of the regulation. If we look at the experience of the University of Trento (where the Author worked in various research projects since 2003) the last decade has been characterized by recurrent warnings from that University about the excessive simplification of the regulation in case of heavy metals. As an example, in case of waste incineration, a set of heavy metals are managed by summing their concentrations to be compared as sum to the regulation limit: no valorization of the specific knowledge on toxicity is made. In order to point out the consequences of this simplification, a few case-studies demonstrating a potential criticality on the role of Cr VI are discussed. A control methodology integrating the present one is discussed in this article, to propose a solution suitable to avoid under-estimations of human exposure to heavy metals from incineration and co-incineration. This approach is particularly important when special waste is combusted as the composition of the input can present heavy metals concentrations higher than municipal solid waste.

“…In the transitory path towards a globally sustainable policy, waste can represent a resource to be valued energetically, especially in those emerging countries where growth in terms of population and production is rapid and only rarely is accompanied by energy development planning [23][24][25][26][27], or considered into the local actions of the CoM initiative due to the economic costs. The focus of the work is to provide a statistical analysis of the first 10 years of the CoM initiative and its status of implementation in terms of baseline of GHG footprint and mitigation actions.…”

Covenant of Mayor was launched in 2008 as a voluntary initiative for local administrations that intend to adopt a plan of interventions concerning greenhouse gas mitigations, achieving and exceeding the EU climate and energy targets. In its first decade of activity, Covenant of Mayors has become the world's largest initiative based on actions of energy saving and local climate mitigation, involving 250+ million inhabitants and 7700+ signatories in more than 50 countries worldwide, under the denomination of Global Covenant of Mayors for Climate and Energy. Globally, a total 5996 municipalities subscribed to the above-mentioned agreement in the first decade, in addition to 1743 progress plans and a wide database of indications regarding successful actions of Greenhouse Gas footprint mitigation at a European scale. This work reports on the global statistics of the initiative in the period 2008-2017 and the geographical location of the signatories within the territory of the European Union, highlighting limits and challenges of the initiative.

“…Nowadays, energy, economy, and environment issues are becoming increasingly complicated, which attracts the general attention of governments around the world [1][2][3][4][5][6]. The traditional waste disposal methods applied most are landfill and incineration, which have been conducted in waste incineration power plants in Denmark and landfill in China.…”

With the accelerated development of urbanization, waste disposal has become a tough problem. If waste cannot be disposed properly, it will lead to environment pollution and waste of resources. Since the energy utilization of the Waste Processing Base (WPB) has not been considered thoroughly, optimal planning of the Multi-Energy Circular System (MECS) coupled with the WPB is studied in this paper. Based on a typical WPB, this paper adds Power to Gas (P2G) and energy storage equipment, and applies a bi-level optimization model to optimize energy utilization. The minimum of total annual cost is the objective of the upper model, whose decision variables are the capacity of each equipment. The minimum annual operating cost is the lower model’s objective whose decision variables are the control parameters of certain energy equipment. Finally, a practical WPB is used for the demonstration and simulation of the proposed planning scheme. The analysis of the simulation results indicates that the collaborative optimization of the MECS coupled with WPB is effective, and improves the benefits of energy, economy, and environment enormously.
