Project

Trackdéchets is a web platform of the Ministry of Ecological Transition enabling the dematerialization of hazardous waste traceability.

This is a project with strong business and regulatory constraints, whose infrastructure must manage +200k requests/min, with a continuity of service requirement for its ~400k user establishments.

Being a platform of the French state with confidentiality stakes (confidential data of companies), all infrastructure is hosted in France, on sovereign services, in SecNumCloud zones.
