Developing a Circular Economy for the Data Centre Industry – how the CEDaCI project contributes to sustainable decision making

Data centres (DCs) house data processing and storage equipment. The data centre industry (DCI) is evolving rapidly, as society is becoming more dependent on digital technologies. Currently, there are 7.2 million DCs globally and provision is predicted to grow fivefold by 2030. The sector already utilises millions of tonnes of resources, including Critical Raw Materials, and the demand will only increase. DCI is based on a linear economy; recycling and materials reclamation infrastructure are also inadequate. At the end-of-life, many materials are either lost to landfill, incinerated, or unaccounted for. Furthermore, many virgin materials are located in geopolitically sensitive locations, which poses a threat to the supply chain that the sector relies on. The CEDaCI project aims to increase overall sectoral sustainability by addressing the various technical, cultural, and behavioural barriers across the DCI, such as fragmentation and sole focus on the energy efficiency. This paper describes the whole-systems approach and CEDaCI project outputs, including bespoke Eco-design guidelines, strategies, and digital tools to extend product life and recycling, and enable better decision-making to increase circularity in the DCI, prepare and support the implementation of the EU Circular Economy Action Plan and ensure a secure, sustainable resource supply chain.
