The CEDaCI project is a unique, ground-breaking venture developing a Circular Economy for the data centre industry. This is particularly important in view of the launch of the EU Circular Economy Action Plan in 2020 and parallel UK plans. The presentation will include a review of CEDaCI activity and output to date including the CDCC – Circular Data Centre Compass. This free online tool is being developed to support procurement teams, operators, designers and manufacturers so they can make more informed decisions about economic, environmental and social sustainability for their businesses and be better prepared to meet the criteria in the CE Action Plan. The tool also includes an innovative Criticality Indicator that shows the type and mass of critical raw materials used in different equipment.
