The street cleaning project in La Cartuja integrates the deployment of street cleaning solutions in the La Cartuja area in Seville. To maximise efficiency in service provision, Althenia deploys two teams of professionals to ensure a 24-hour uninterrupted service. During the day shift, manual cleaning operations are carried out. During the night shift, cleaning solutions are carried out with mechanical sweepers and street sweeping.

In developing its cleaning solutions, Althenia uses specialised techniques and machinery such as road sweepers, hot water pressure washers and light vehicles.
