Annual Congress Circulaire-IT

The Annual Congress Circulaire-IT (Jaarcongres Circulaire-IT) will take place on 14 November 2023. The success of the previous edition has resulted in the event taking on a more international approach for the coming event. The congress will run throughout the day and is aimed at all professionals involved in circular IT, both directly and indirectly. The event targets partners, manufacturers, service providers, and (potential) end-users, offering substantive presentations and networking opportunities with other entities within their own and other industries.

The Annual Congress Circulaire-IT is the first and only international congress in the Netherlands that addresses the reduction of IT waste, and creates a platform for providers of circular products and services. Circular IT clearly has an international dimension, with cross-border consolidation and supply chains. Therefore, the primary language is English, and speakers from across Europe will share their experiences.
