The Société Wallonne de Financement Complémentaire des Infrastructures (Sofico) reported on Tuesday that approximately 840 tonnes of rubbish were collected from Walloon motorways in 2024, costing over €3 million, as they launched a new awareness campaign.
These figures include litter left on central and side verges, as well as non-concession motorway areas, and cover waste collected from entrance and exit ramps, though not from bins at rest areas.
In 2023, Sofico had collected 767 tonnes of rubbish from Walloon motorways with a budget of €3.5 million.
Sofico laments that vast amounts of waste are collected each year, requiring substantial budgets that could be allocated to road renovation and maintenance projects.
In response to this issue, Sofico is launching a new awareness campaign called “Trash,” featuring displays on 300 signs along Walloon motorways and national roads from 15 July to 31 August, along with a video shared on social media.
The campaign stresses that small waste generated during a journey should be kept in the vehicle and disposed of in designated bins at rest areas or upon reaching the destination. Waste from one’s home must not be discarded on the network or in its bins, as this constitutes illegal dumping.
