Energy from waste
In recent years we have been seeing a gradual increase in the percentage of incinerators capable of energy recovery from municipal solid waste (MSW). The waste that can be assimilated to renewable sources are a resource to be exploited as much as possible given the synergy between the availability of fuel at no cost and the potential solution to the related problem of disposal. Some of the most prevalent technological issues in the industry and on which major national and international research efforts concentrate mainly concern the increase in efficiency of incinerators with energy recovery (WTE - waste to energy), corrosion problems of some critical components that limit its duration and increase operating costs, and the increase in the abatement efficiency of gas treatment systems.
In particular, some research efforts have focused on the development of new materials and coatings for corrosion protection and new technologies, reliable and low cost for their application, on the development of new engineering solutions concerning gas treatment, on the assessment of innovative catalytic materials that increase the abatement efficiency of pollutants, on the study of the mechanisms of formation of organic micro pollutants, on the analysis and the definition of criteria for monitoring emissions. In particular with a view to minimize the number of production sites required and to overcome, at the same time, some technological aspects which limit the attainment of higher yields, a possible option is the integration between the incinerators and traditional thermal power plants.
The activities carried out by RSE in this field have the following objectives:
. Develop innovative technologies for the application of coatings for the corrosion protection of plant components which currently constitute the technological barrier for energy recovery at higher temperatures of the waste to energy plants;
. Assess the technical and economic convenience of the integration option between incineration and combined cycles;
. Ascertain the performance systems limiting emissions of gaseous pollutants (organic micro pollutants, dioxins, etc.) of the WTE plants
. Develop innovative techniques for the determination of the biogenic fraction of waste treated in incinerators . Characterize and develop the law relating to the Secondary Solid Fuels (CSS) or develop innovative corrosion monitoring and perform measurement campaigns in large-scale co-firing of waste (CSS)-coal
