Abstract

Every year around 50 millions Mg solid waste are incinerated in Europe. Large differences exist in different regions, mainly regarding energy recovery, flue gas treatment and management of solid residues. This paper aims to identify and quantify those differences, providing a Life Cycle Assessment of two incinerator systems that are representative of conditions in Northern and Southern Europe. The two case studies are Aarhus (Denmark) and Milan (Italy). The results show that waste incineration appears more environmentally friendly in the Danish case than in the Italian one, due to the higher energy recovery and to local conditions, e.g. substitution of electricity and heat in the area. Focusing on the incineration process, Milan incinerator performs better than Aarhus, since its upstream impacts (related to the production of chemicals used in flue gas cleaning) are more than compensated by lower emissions at the stack. Consequently a more efficient flue gas cleaning as it is in the Italian case appears to be more environmentally friendly than the Danish one.
