In June 2012, Valenciennes city entrusted SUEZ with the collection and sorting of its household waste. The objectives were twofold:
- optimise the organisation of waste collection;
- reduce sorting errors at the source.
Reduce the fuel consumption of waste collection trucks
Regarding waste collection, SUEZ reorganised the collection rounds with a view to reducing the number of kilometres travelled by 15%. By implementing brake energy recovery systems on the trucks, we also lowered their fuel consumption, CO2 emissions and noise levels.
Raise awareness among the local population
In order to improve sorting practices at the source, we sent out three experts to explain waste sorting guidelines to users. During collection, stickers on the bins indicate common sorting errors. Our experts also carried out door-to-door visits to remind the inhabitants of the importance of sorting their waste and to point out the common mistakes to be avoided. To reach the maximum number of inhabitants, they also spoke in schools, retirement homes, collective housing, etc.
Increase communication about sorting practices
Users now have access to a website giving them all the information they need on waste collection and sorting.
In addition, satisfaction surveys are regularly conducted with a view to evaluating and improving our services.
SUEZ is also committed to continuously improving recycling performance and to adapting its processes to future changes in waste sorting guidelines in France.
