CAPTURE RATES OF SOURCE SEPARATED ORGANICS: A COMPARISON ACROSS EU, WITH A FOCUS ON METROPOLITAN AREAS M. Giavini*, C. Garaffa**, S. Cantoni ***, E.

In Mediterranean and Scandinavian countries, and partly in the UK, kerbside collection of food waste is kept separate from garden waste collection, while in central Europe (e.g. Germany, Netherlands, Belgium) the two streams are collected commingled. A comparative assessment is presented in this study with a focus on large metropolitan areas, namely Milan (IT), Munich (DE), Bristol (UK), Barcelona (ES). Methods and Data, Description of Case Study, etc. This study is based on official data, made available through government reports : WRAP for UK, ISPRA for IT, ARC for ES, VHE for DE. Furthermore, direct field surveys have been carried out for specific case studies. in particular Milan (Italy) have been investigated more deeply; here residential food waste collection with an intensive kerbside sheme is being rolled out for 1.300.000 inhabitants by the end of 2013. Results Looking at averages, the Catalan and Italian residential food waste collection scheme is achieving the highest food waste captures. The overall capture of organics is more or less the same as in Germany, with an important remark: in Italy green waste collection is usually not performed kerbside (which could lead to an additional capture of 60-80 kg/inhabitant.year) but relies on bring systems.
