Ipalle has been adapting and expanding its waste disposal plant since the 1990’s. From 1992 to 1996, the addition of equipment to the sorting, composting and incineration plant were managed. The project included a flue gas cleaning equipment and an aerobic composting of “green” waste. From 1995 to 2004 were managed the extension of the Solid Waste incineration plant with the addition of 2 incineration units and the refurbishment of existing facilities. A flue gas treatment equipment is installed in accordance with DUE/94 regulation (dangerous waste). The bottom ash treatment facility was extended. From 2002 to 2011, a third incineration stream was added, designed to burn 12 tons of waste per hour. A sludge combustion device with pulverization in the combustion chamber was installed, as well as a SCR Denox flue gas treatment for 3 incineration units. From 2006 to 2012 followed the study and installation of a fourth incineration stream (n°7).
