The state of the art on Municipal Solid Waste (MSW) management is based on the domestic separation of materials produced. After domestic separation, the resident has to transfer the separated materials to the MSW manager through the hands of collection workers. It is exactly at this stage that an end-use product changes its status and property becomes waste. This paper analyzes and compares the opinions and awareness of citizens and kerbside collection workers on this subject by means of two structured questionnaires in the city of Mercato San Severino (about 22,000 people), in Southern Italy.
