Design for Circularity: A Data Centre Equipment Case Study
This analysis explores the critical need for circular design in the rapidly expanding data centre industry, particularly in the context of increasing AI adoption. We present a case study of a prototype circular server, quantifying its environmental benefits and advocating for a shift from linear to circular product lifecycles to enhance resource efficiency and sustainability.
The Urgent Need for Circular IT Infrastructure
The data centre industry faces unprecedented growth, driven by digital transformation and AI. This expansion, however, comes with significant environmental costs. Our research highlights key areas of impact and the transformative potential of circular design.

Mounting Resource Demands
The rapid expansion of the data centre industry, intensified by the adoption of Artificial Intelligence (AI), places immense pressure on critical resources. Energy consumption is projected to nearly double by 2030, with a potential rise to 1,700 TWh/year by 2035 if AI accelerates. Water demand for cooling and power generation is expected to reach 4.2-6.6 billion cubic meters by 2027. Land use for new data centres is projected to increase by 78% globally. Furthermore, the manufacturing of digital technology is highly resource-intensive, with servers containing numerous Critical Raw Materials (CRMs) that face supply threats and have low recycling rates. E-waste is the fastest growing global waste stream, with only 22% formally recycled, leading to significant material losses and environmental hazards.
Embracing Circular Design
Despite the critical role of design in determining up to 80% of a product's environmental impact, data centre equipment has historically focused on the use phase, neglecting end-of-life considerations. The shift to circular design is urgent for resource efficiency and supply chain security. This involves dematerialisation, product life extension (reuse, refurbishment, remanufacture), and advanced materials reclamation. Guidelines from the EU Circular Economy Action Plan and the 'Right to Repair' are driving change. Our prototype circular server exemplifies these principles, demonstrating a 33% reduction in overall product mass and a 68% reduction in plastic components through modularity, standardised parts, and simplified assembly for repair and component recovery.
Quantifying Sustainability Benefits
Comparative Life Cycle Assessments (LCAs) reveal significant environmental benefits of circular design. The prototype circular server demonstrates an overall impact that is 15% lower than a standard non-circular server. Specifically, recycling via the advanced TND process (Terra Nova Développement) leads to a 24% lower impact compared to Business-As-Usual (BAU) recycling. Product life extension through refurbishment, which involves reusing all parts except electronics, results in a 23% lower impact than replacing servers every four years. Over a 16-year period, the prototype circular server's total impact is on average 29% lower than a standard non-circular server, underscoring the substantial environmental advantages of design for circularity.

| Feature | Standard Server Design | Prototype Circular Server (PCS) Design |
|---|---|---|
| Chassis Design | Specific, often complex, limited reuse across generations. | Modular, flat base, lids of different depth to accommodate form factors, reusable across generations and models. |
| Component Modularity | Unique designs restrict reuse to same models, fixing points change between models. | Standardised interchangeable parts, components and fixing types are consistent across generations and models. |
| Fastenings/Fixings | Often over-engineered, many fixings (e.g., 103 components) making disassembly challenging. | Rationalised fixings (e.g., reduced to 46 components), single screw for motherboard, fan PCB clips on/off. |
| Plastic Components | Includes non-recyclable fire-retardant coated plastics. | Plastic mass reduced by 68%, metals replace plastics where possible to increase recycling potential. |
| Recycling Potential | Limited to 4 common metals (Fe, Al, Cu, Au) in BAU scenario, many materials deemed uneconomical to reclaim. | Designed for easier material separation and component recovery, supports advanced reclamation processes (TND scenario) for wider range of CRMs. |
Prototype Circular Server: A Model for Sustainable IT
The Prototype Circular Server (PCS) represents a significant leap towards sustainable data centre equipment. Unlike traditional designs, the PCS is modular and engineered for ease of assembly and disassembly. Its chassis is designed for reuse across generations, featuring a flat base and adaptable lids. Critical innovations include standardised, interchangeable parts that allow components like CPUs, RAM, and storage to be swapped or upgraded efficiently, extending product life. The motherboard is secured with a single screw, and fan PCBs clip on and off. A redesigned universal disk caddy accommodates both 2.5-inch and 3.5-inch drives, streamlining maintenance.
Crucially, the PCS significantly reduces environmental impact through dematerialisation, resulting in a 33% lower overall product mass compared to older servers. Non-recyclable plastics were drastically reduced by 68%, with metals replacing them where feasible to boost recycling potential. The number of fastenings and components was cut from 103 to 46, simplifying repair and component recovery. These design choices contribute to a 15% lower overall environmental impact than a standard server, demonstrating the tangible benefits of a circular approach.

Your Roadmap to Circular IT
Transitioning to circular data centre practices is a strategic journey. Here’s a typical phased approach to integrate design for circularity and sustainable AI infrastructure into your enterprise.
Phase 01: Policy & Regulation Adaptation
Integrate new EU/UK regulations like 'Right to Repair' and updated Ecodesign guidelines into procurement and IT lifecycle management strategies. Assess internal policies for alignment with circular economy principles.
Phase 02: Ecodesign & Prototyping
Utilise ecodesign evaluation tools (like EET) to assess and redesign IT equipment for modularity, dematerialisation, and product life extension. Explore prototyping circular components and servers.
Phase 03: Supply Chain Integration
Establish partnerships for advanced CRM reclamation and high-quality recycling. Implement processes for component reuse and refurbishment within your supply chain, prioritising security and data cleansing.
Phase 04: Market Adoption & Scalability
Pilot circular IT solutions within your operations. Advocate for and adopt open-source software/firmware. Collaborate with manufacturers to scale the commercialisation of modular, long-life IT equipment.
Phase 05: Continuous Impact Assessment
Regularly perform updated Life Cycle Assessments (LCAs) to monitor environmental impacts. Incorporate economic and social impact assessments. Adapt strategies based on regional data and evolving technological advancements.
