The Intermunicipal Community of the Tâmega e Sousa is a public entity composed of 11 municipalities in Northern Portugal. It has developed a circular project aiming to enhance circular economy achievements and green transition agendas within local authorities, municipal companies and intermunicipal entities. In this regard, it has created the manual Economia Circular nas Compras Públicas on circular economy in public procurement to assist municipalities.

The manual presents an in-depth mapping of circular economy practices for a Portuguese strategy for ecological public procurement, as well as indications on how to address the circular economy challenge, with a range of criteria and procedures for public procurement.
