Why are there blue, yellow, grey and green trash cans in the streets of Paderborn?
Participants of this semester’s course “Technical German for foreign students” asked themselves. Mechthild Hoppmeier (photo left in the back) gave an overview of the diverse communal waste management concepts for municipal waste in the city of Paderborn. She explained in detail the ecological and legal reasons for this complex collection of waste. Blue cans for example are for collecting paper. Arash Eftekhar presented the various waste logistic and procedural process steps from collecting and processing of wastepaper to the production of new paper. He also compared the collection system utilized Paderborn, which is very successful in his opinion, with conditions in Iranian hometown. Heidi Seddik informed about the whereabouts of the residual waste collected in the grey cans from using the contained thermal energy to the final storage of incineration residues. When the participants talk about their time in Paderborn once they are back home, they will also include Paderborn’s colorful waste management.
