Overview
The waste to energy plant is located in Modena in Via Cavazza 45 and is part of a multifunctional hub. The hub also includes a physical/chemical treatment plant for liquid waste managed by Herambiente S.p.A. and of the wastewater treatment plant for the city of Modena managed by Hera S.p.A. The first two lines of the plant, each with a capacity of 140 tons per day, entered into operation in 1980. Subsequently, a third line was built according to the criteria provided for by Presidential Decree 915/82 and with a nominal capacity of 250 tons per day. When the plant came into operation in the early 1990s, the total annual maximum amount of treatable municipal solid waste was 140,000 tonnes per year, while the maximum amount of treatable medical waste did not exceed 5,000 tonnes per year. The lines described above were decommissioned in September 2009 and definitively demolished between May and December 2011 to make way for the new plant. The fourth line was launched in December 2008 for functional testing and in April 2009 for testing with waste. It became fully operational a year later. Page updated on dd/month/yyyy

Technology
How is the plant built?
The plant as a whole currently has the following configuration: a waste receiving, storage and feeding section; a combustion line with a mobile grate furnace equipped with a recovery boiler and flue gas cleaning system; and a power generation plant set up for thermal energy recovery.
The plant is equipped with a Continuous Emissions Monitoring System (CEMS) which has automatic analysers functioning 24 hours per day to continuously monitor the quality of atmospheric emissions. A suitably heated sample probe continuously transports a sample of the gas from the plant´s chimney to the analysis booth where the instrumentation is installed. The sample is put into the Fourier transform infrared spectroscopy (FTIR) analyser, which continuously detects the absorption spectra of the compounds to be measured. A mathematical process is used to compare the spectra with the typical spectra of the substances being investigated. The comparison makes it possible to determine the quantitative values (concentrations) of the elements and compounds analysed. Besides the FTIR system, there are other continuous analysers and meters needed to complete the fume analysis by determining other parameters such as: particles, organic compounds, mercury, oxygen, temperature, flow and pressure. A data acquisition system (SADE) also continuously provides the values obtained by calculating the half-hourly and daily averages of the concentrations measured, which are compared with the maximum admissible limit values set by the Control Bodies. These data are also provided on the group´s website, where they are automatically updated every half hour.
