Overview
The waste to energy plant in Bologna processes solid urban waste and non hazardous and hazardous special waste (healthcare with an infectious risk).
The construction of the plant began in 1971 with the construction of three disposal lines with a potential of 200 tons of waste per day each. The first two lines went into operation in 1973, while the third began to be used the following year. From 1987 to 1997, the plant underwent various plant and technological modifications to adapt to constantly evolving European legislation.
The Bologna waste to energy plant underwent a technological modernization and redevelopment work in 2001, completed in 2004. Since then it has had the same plant configuration. The structure consists of 2 parallel and independent waste to energy lines, which each treat 300 tons of waste per day, with relative energy recovery implemented through a cogeneration plant. The plant produces approximately 140 million kWh per year of electricity destined for the national grid, and approximately 45 million Mcal per year of thermal energy for the district heating network.
The technological characteristics of the plant have been selected paying particular attention to the criteria of maximum guarantee of environmental protection, reliability and operational safety, technological process and product innovation and high energy efficiency.

A continuous monitoring system, installed on the chimney, analyses all the main parameters at one minute intervals, then stores and logs them according to national laws. The data are transmitted to the controlling bodies. All testing equipment is certified by TÜV (German Certification Body), in order to offer the best guarantees of quality and reliability. The continuously monitored parameters are: CO (carbon monoxide), CO2 (carbon dioxide), SPM (suspended particulate matter), SOx (sulfur oxides), NOx (nitrogen oxides), NH3 (ammonia), HF (hydrogen fluoride), HCl (hydrochloric acid), TOC (total organic carbon), O2 (oxygen), temperature, humidity and fumes pressure. Periodically, further tests are carried out with direct sampling in the chimney, using instruments and methods provided for by law; these measurements are performed by accredited laboratories. It should be noted that the limit values prescribed for atmospheric emissions by local authorities are much more restrictive than those established at national level. Since 2009, the control over emissions to the atmosphere has been increased through sampling and the discontinuous analysis of PCDD + PCDF (dioxins) and Hg (mercury) parameters. Furthermore, a backup system for gas analysis at the chimney has been installed, guaranteeing continuous monitoring also in case of main system failure.
