Support Aix-en-Provence, France, in getting its tourists attractiveness back

The municipality of Aix-en-Provence chose smart waste technology to improve the management of its waste collection, which has in past years damaged its image for tourists and inhabitants alike. This SUEZ innovation optimises waste collection, making the town a more pleasant place for all
The mission

Adapt waste collection schedules to container fill rates

Aix-en-Provence is an iconic city of southeastern France, very popular with tourists at certain times of the year. Waste production therefore fluctuates significantly. The standard collection schedule at voluntary waste disposal sites was not adapted to their actual use. At certain periods, the containers were overflowing, causing nuisances and complaints from residents and visitors alike. At others, waste collection rounds were being made when the containers were still half empty.
Faced with this situation, the Agglomeration Community of Pays d'Aix tasked SUEZ with optimising waste collection via a smart remote measurement solution.

Our solution

Use a remote measurement solution to optimise collection at voluntary waste disposal sites

To ensure clean streets and streamline collection costs, SUEZ set up a system to predict the fill rate of containers at voluntary waste disposal sites throughout the agglomeration. 
 
Sensors placed in the waste containers analyse their fill rate. These sensors are linked to a remote reading system developed by SigrenEa, a subsidiary 100% owned by SUEZ, and communicated in real time to the municipality's technical services. This allows for anticipating and determining the routes of the city's fleet of waste collection vehicles depending on the precise needs at each waste disposal site, emptying the containers just before they start to overflow.
This Smart Waste technology ensures efficient waste collection scheduling while reducing costs and minimising the impact on both the environment and the city's inhabitants. 
The results
Currently, the average fill level of the waste containers at collection is 75%. 
Costs have been reduced by optimising the waste collection routes, which also allows for reducing the average fuel consumption of the vehicles.
The goal of zero overflow and zero complaints to the city authorities has been practically achieved.
