Progetto NO-GAS. Rapporto tecnico finale

NO-GAS Project, funded in the framework of the Innovation hub "Renewable Energy and Energy Efficiency Technologies for the Sustainable Management of environmental resources", focuses on emissions from landfills, both punctual (from the chimneys of wells uptake, by torches and, if they exist, from the chimneys of incinerators) and spread (through cover). These form the main part of CH4 emissions and volatile organic compounds (VOC) in the environment. The evaluation of the amount of carbon emitted in its various forms from a landfill is very important for quantitative evaluation at regional and national scale. The project aims to achieve the following objectives: o codify a standardized procedure to estimate spread flows; o develop a model to quantify and characterize the emissions on a regional scale; o develop an integrated methodology to characterize geo-environmental site used as a dump by remote sensing data and that both support the study of air quality; o verify and increase the efficiency of surface coverage; o check the efficiency of biogas collection for use in cogeneration plants for electricity production. The objectives will be achieved by means of methods based on evaluation procedures internationally accredited, in particular between the methods for measuring the flow of common plants RSU and similar to the accumulation chamber. The flow data acquired will be processed by methods coming both from statistics and the mining geostatistics (eg. Conditional simulations), to allow a quantification of emissions of biogas from landfill and to associate to this value an estimate of the error. After identifying the areas with a high flow spread you can take action to reduce these emissions is on improving the system of coverage that the collection system by defining a more effective model of intervention and management. They will also be applied to diverse methods of analysis and assessment of air quality including remote sensing and multitemporal analysis.
