Choosing the most appropriate selective collection model in the municipality requires an impact assessment on data protection. The City Council, in view of the powers it has been assigned in matters of waste management, would be entitled to carry out the processing of data arising from the implementation of the selective collection system. However, in the absence of a specific legal provision, the development of profiles that produce legal effects on the person using the service or that significantly affect them in a similar way, requires the explicit consent of the persons affected. The participation of third parties in the implementation of this system requires the formalization of a contract of manager and, where applicable, of sub-manager, as well as, where applicable, the fulfillment of the obligations established in this regard in the LCSP.
