A Circular Economy for the Data Center Industry
Lets Talk Tech is giving visibility to a notable woman in STEM integrating environmental sustainability to innovation in design and engineering.
Professor Deborah Andrews, Design for Sustainability and Circularity, School of Engineering, @Londonsouthbankuni .
Dr Andrews supports the data center industry since 2010, an industry that emits the same amount of carbon as the airline industry, to transition to an environmentally sustainable model.
Building life cycle sustainability not just energy efficiency
With a background in product design and industrial design and interest in environmental issues trying to improve the footprint of products services and systems, she became involved in building the life cycle sustainability assessment of data centers to identify problem areas because the industry is still focused on operational energy efficiency and that’s not enough.
Data centers large contributor to WEEE
The industry expanded exponentially and will continue to do so with computing in relation to AI. We need to think about materials and embodied impacts of equipment designed in a linear fashion whereby we take materials, make stuff, use it and we don’t think about what will happen at the end of life which is a problem with electrical and electronic products. Waste electrical and electronic equipment (WEEE) is the fastest growing waste stream in the world. The data center industry is contributing to that.
Professor Andrews is the leader of CEDaCI project kickstarting the circular economy for the data center industry whereby we think at the design stage what will happen to the product , how can we change the design to be easily disassembled, components can be separated to increase recycling rate and increase product life. A lot of equipment is taken out of service when it still functions well. How can we improve recycling and reclamation of materials at end of life.
AI increases the need for circular equipment
In order to accommodate the compute required for AI, the sector will have to treble with 2030. So the need to design more circular equipment AI increased the need to design products that can be disassembled and reused.
Academic research needed to help the industry’s environmental footprint
There is a gap between academia and the industry. We need to help the industry face the scale of the problem we are facing and to present empirical evidence to show how a change in business practice can improve companies profiles. Some of the challenges is that companies are focusing on carbon reduction mainly in relation to operational energy but there are still no tools to show the embodied impact of products associated with the sector. Through the CEDaCI project, we collected primary source data and built a tool to help stakeholders make informed decisions about equipment they buy, what to do when equipment appears to be reaching industry’s perception end of life.
The Challenge of Stakeholder buy-in to circularity
From our experience working with representatives of the sector, they fall in 2 camps. People who are open to learning about changes and those who reject the idea without really understanding whats going on.
The Challenge of Adequate WEEE Recycling Infrastructure
Behaviour is part of the challenge but also having an adequate infrastructure to take equipment and recycle it properly is another challenge. Its easy for industry to tick CSR boxes and conform to legislation. But recycling companies are not doing enough. The main material that is being recycled is anything with iron in it, steel based material, copper, aluminium and gold.
Critical materials for data centers
There are 12 critical materials in circuit boards which if we don’t have those we don’t have data centers or any digital communication. They are critical because of the amount left in earth that is not yet mined, less then 1% recycling rate, the location where the reserves are found in geopolitically sensitive areas. These materials of high technical and economic significance are wasted, dumped in landfill.
Mining raw materials or metals efficiency
Policy for second product life market is developing in Europe and a non profit called Free ICT Europe campaigning and pushing for support of this secondary market. This drive can save purchasers money but also a significant environmental benefit, keeping materials in use longer rather than mining new materials.
Circularity requires legislation and investment
Energy efficiency was driven by legislation, there hasn’t been any related to physical resource efficiency. There is a massive investment opportunity for data center companies to think more holistically not just about building and running sites but also thinking about investing in recycling capabilities.
