Nature-Positive Data Centres: How the Tech Sector Can Build Sustainable AI Infrastructure - Circularity and Supply Chain Edit
Introduction
In last week’s article, I explored how the tech industry, and specifically data centre operators, can adopt a nature-positive approach, focusing on water stewardship and land management. As the UAE emerges as a global hub for AI and digital infrastructure, sustainability executives in tech and data centre operations face increasing pressure to ensure green, energy-efficient, and nature-positive data centres. Integrating sustainable AI infrastructure and circular design principles into operations not only supports environmental stewardship but also provides a strategic advantage in the competitive Middle East technology market.
This week, we turn our attention to circularity and supply chain management, two critical levers for building sustainable data centres. From sourcing recycled and low-impact materials to optimizing hardware life cycles and developing robust e-waste recycling programs, these strategies reduce ecological footprints, lower operational risk, and enhance regulatory compliance. For leaders in the UAE, integrating nature-positive design principles into AI infrastructure and data centre operations is not just good governance, it is a strategic advantage in a rapidly digitising, environmentally conscious market.
Lets start with Circularity =>
Circularity
Data centre hardware sustainability is critical across the full lifecycle—from manufacturing and packaging to transport, deployment, and end-of-life disposal. With global e-waste reaching 62 billion kilograms in 2022 and projected to grow to 82 billion kilograms by 2030, tech companies must adopt circular data centre design to minimize environmental impact.
Key nature-related impacts and dependencies include:
Hardware value chain impacts: Manufacturing requires vast raw materials, energy, and logistics, contributing to resource depletion and emissions.
E-waste and pollution: At least a quarter of e-waste ends up in landfills, releasing toxic metals such as mercury, arsenic, and lead that contaminate soil and water.
End-of-life GHG emissions: Burning e-waste and refrigerant releases (HCFCs and HFCs) generate potent greenhouse gas emissions.
Resource use in recycling: Hydrometallurgical recycling consumes large volumes of water, while pyrometallurgical methods are energy-intensive, highlighting trade-offs in circular processes.
1. Design for Circularity and Repairability
Hardware and process design should embed circularity from the outset. This includes using recycled materials and modular designs that support easy repair and component replacement. Recycled metals are 2–10 times more energy-efficient than virgin metals, significantly reducing the environmental footprint of new products. These principles apply across semiconductors, data centre infrastructure, and other hardware, helping companies create more sustainable, nature-positive operations.
2. Extend Equipment Lifespan
Focus on maintaining and replacing individual components to prolong product life. Products should be designed for easy dismantling, refurbishment, and recycling, supporting end-of-life sustainability. By planning across the full product lifecycle, companies optimise resource efficiency and reduce waste, while minimising both planned and inadvertent obsolescence.
3. Embed Digital Circularity Practices
Digital sustainability extends beyond physical hardware to digital resources. Minimizing unnecessary data reduces storage, computing, and network demands, delays hardware refresh cycles, and lowers e-waste. Proactive digital housekeeping, such as implementing retention policies, de-duplicating files, optimizing data formats, and removing redundant datasets, further decreases the environmental footprint and supports green AI operations.
4. Develop Repair Infrastructure
Beyond design, companies should prioritise reuse to reduce e-waste from hardware refreshes. Extending product life through component replacement, maintenance, and refurbishment, rather than full replacement, minimizes environmental impact. This requires establishing collection systems, repair facilities, and consumer awareness programs to support a circular lifecycle.
Example:
Apple has a network of over 5,000 certified repair locations to support consumers in extending their product lifespan.
5. Establish Collection Programs
Implement programs that simplify recycling, promote proper disposal at authorized facilities, and recover usable components from end-of-life devices. Providing accessible drop-off points prevents additional landfill waste and ensures a steady supply of materials for new products. Data centres can adopt similar zero-waste initiatives to safely cycle out old hardware and support a circular, sustainable operation.
Example:
Microsoft has implemented policies around managing waste, utilizing regional Circular Centers focused on e-waste from its data centres. These sites centralize collection and contribute to Microsoft recycling or reusing over 90% of its decommissioned computer servers and other technologies within data centres in 2024.
6. E-Waste Recycling Infrastructure
Expanding recycling capacity is essential to recover valuable metals and reduce environmental impact. In 2022, only 60% of the 31 billion kilograms of metals in e-waste were recovered, leaving over $60 billion of value in landfills. Tech companies can play dual roles, purchasing recycled materials and supplying end-of-life electronics for processing, creating a circular supply chain and supporting sustainable, nature-positive operations.
Example:
Western Digital has partnered with Microsoft, Critical Materials Recycling and PedalPoint Recycling to collect obsolete drives from Microsoft data centres and extract rare earth metals, as well as gold, copper, aluminium and steel. Still in its first year, the partnership has showed promising results, processing over 20,000 kg of drives.
7. Adopt Pollution and Waste Controls
Minimize environmental contamination by implementing advanced waste management systems and setting zero-waste-to-landfill standards (e.g., UL2799). Begin with process-level monitoring to optimise resource use and quickly address leaks or inefficiencies. Tracking outputs enables a comprehensive waste management strategy, including separation, collection, and identifying opportunities to repurpose or reuse materials.
In semiconductor manufacturing, wastewater can be filtered, with a portion of extracted chemicals recovered for reuse. Similarly, solid waste from manufacturing or e-waste processing can have harmful chemicals removed, allowing remaining by-products to be repurposed in industrial applications such as construction, supporting circularity and resource efficiency.
When operations produce significant waste heat, it can harm local ecosystems if discharged, without being cooled. (This was one of the first things I did when I graduated in engineering!) Capturing and reusing this heat within the facility or nearby locations reduces environmental impact. At a minimum, setting local discharge temperature standards helps protect surrounding ecosystems and supports sustainable operations.
Example:
Incorporating these actions often offers commercial opportunities. In 2023, TSMC derived ~$40 million in benefit from resource circulation, achieved through a 96% waste recycling rate.Meanwhile in Denmark, Microsoft is leveraging surplus data centre heat for district heating.
8. Invest In Pollution Rehabilitation
Rehabilitate land and water areas affected by pollution or waste by supporting targeted restoration initiatives. Even with strong controls, some impacts may occur, proactively restoring ecosystems enables companies to move beyond mitigation toward true nature-positive outcomes.
Example:
Samsung has launched a partnership with Seatrees, which focuses on restoring marine ecosystems using its own technology in support.
And now, Supply Chain Management…
Supply Chain Management
1. Suppliers with Sustainability Certificates
Tech companies should partner with suppliers holding recognized sustainability certifications and verified impact assessments, ensuring environmental responsibility across the value chain. Beyond certification, requesting product-level data on nature-loss drivers allows companies to prioritise suppliers reporting on environmental impacts, supporting informed procurement decisions and targeted improvements.
Example: ASUS has adopted a nuanced supplier grading management system. ISO 14001 certification is mandatory for all qualified suppliers, with additional requirements for specific issues. On water, motherboard suppliers must submit annual wastewater discharge testing reports. Suppliers who use substantive amounts of freshwater must identify mitigation measures if located near biodiversity-sensitive areas. In most cases, adopting a tiered approach to identify and manage factors with the highest environmental impacts, along with their corresponding suppliers, can improve the effectiveness of collaboration.
2. Lower Impact Metals, Minerals
Work with suppliers providing recycled or lower-impact materials, and partner with mining companies committed to biodiversity management, community stewardship, and ecosystem restoration. By sourcing responsibly, tech companies can strengthen their supply chains, and build resilience, while advancing a nature-positive transition.
Example:
Apple prioritizes recycled inputs: in 2024, the company avoided 6.2 million tonnes of emissions by sourcing recycled and other low-carbon materials, as per ISO 14021 specifications.
3. Lower Impact Chemicals, Gases
Partner with suppliers to replace high-impact chemicals with low-impact alternatives in semiconductors and cooling systems to reduce emissions and environmental hazards. This approach supports sustainable semiconductor manufacturing and contributes to nature-positive AI infrastructure in the UAE, by reducing negative impacts on air, soil, and water ecosystems, enabling tech companies to lower their environmental footprint without compromising performance.
Example:
Tokyo Electron Limited developed a new etch process for semiconductor manufacturing that reduces the CO2 footprint by using an alternative chemistry to the current process and operating at cryogenic temperatures, reducing GHG emissions by 83%
4. Lower Carbon Building Materials
Seek out zero- or low-carbon alternatives for building materials and other material inputs. Embodied carbon in building materials accounts for 11% of global GHGs.
One data centre company conducted a 30-year life cycle assessment and identified the largest carbon impact as their cooling equipment, due to the lifecycle only being 5-7 years and equipment requiring frequent replacement. When designing, building or updating facilities, accounting for these impacts and targeting more sustainable approaches is critical.
Example:
Microsoft signed a deal with a low-carbon cement startup, Sublime Systems, enabling it to claim 622,500 tonnes of emission reductions over a 6-9 year period.
5. Research and Develop Low Impact Chemicals and Gases
For high-impact chemicals and materials lacking existing substitutes, tech companies can collaborate with suppliers, startups, and research institutions to develop new processes and inputs. Joint R&D programs and incentive schemes accelerate the transition to nature-positive solutions, embedding sustainability early in product design and ensuring a next generation of environmentally responsible technologies.
Example:
Semiconductor firm Micron has partnered with Merck KGaA to develop lower-GWP gases for use in semiconductor manufacturing.
6. Set Supply Chain Commitments
Define expectations for a responsible supply chain across key nature-loss drivers, water, land, pollution, waste, and GHG emissions, while ensuring alignment with regulatory guidance. Consistent engagement with suppliers reinforces responsible practices, enables progress tracking, and highlights successful initiatives, preventing gaps across the value chain.
Example:
Acer calls on suppliers and partners to assess the biodiversity-related risks of their operating sites and to adopt necessary measures to minimize negative impacts in their Nature and Biodiversity Strategy.
Conclusion
As the UAE positions itself as a global AI and digital infrastructure hub, sustainability executives face increasing pressure to ensure that data centres deliver both high-performance compute and nature-positive outcomes. Beyond energy efficiency, the next frontier for green data centres also lies in circularity, sustainable supply chain management, and responsible materials sourcing.
From reducing e-waste and extending hardware lifecycles to adopting low-impact chemicals and supporting ecosystem restoration, these strategies help tech companies lower environmental impact, enhance regulatory compliance, and build resilient, sustainable AI infrastructure.
