Aspetti economico ambientali del termovalorizzatore “Silla 2” di Milano.

Management of waste is a topic that plays a main role in public agenda. The search for possible solutions for a sustainable management of waste is very controversial because, on a side, there is the need to reclaim polluted sites, often with thermovalorization, on the other side there is the position of environmental associations that are opposed to the use of these technologies. In spite of these strong oppositions, there is a growing interest towards thermovalorization both for energy recovery and for the progress coming from technologies of fume treatment and the possibility to consider the problems of urban territory in medium-long term. The progress has been stimulated by European and national rules that highly reduced emission limits. Available technologies for the reduction of emissions are today capable to satisfy prescriptions of the most restrictive rules, as it happened in plant “Silla 2” in Milan. This thermovalorizator is the proof that environmental goals achieved in this technology are more than appreciable; this, anyway, does not mean that thermovalorization use completely clean technologies because still persist environmental impacts, but modern technologies noteworthy decreased emissions and danger.
