Video: The pursuit of sustainable PC design

24 March 2022

Dell Technologies has launched a prototype laptop featuring bio-based components as it looks to increase product content and packaging from recycled or renewable materials as one lever for halving emissions by 2030 and consuming only renewable energy by 2040.

The prototype developed in collaboration with Intel is part of Concept Luna, an initiative aimed at accelerating circular design in electronics. While not intended for commercial sale, the Concept Luna prototype features a printed circuit (PC) board made with flax fiber in the base and water-soluble polymer as the glue, replacing the use of traditional plastic laminates.

“Concept Luna is a challenge our engineering team embraced by asking 'what if' questions to assess our product design in different ways. It has allowed us to test new ways of reducing, reusing, recreating, and ultimately push the boundaries of sustainable PC design. Some of the innovations introduced include using hydro-based aluminum, introducing recycled plastic polymers and bioplastics into our casings, as well as using 100% recycled pulp in our packaging. We have already exceeded our 2030 goal eight years ahead of plan with the launch of the new Latitude notebook which has 100% recyclable packaging,” said Chris Buchanan, director for client solutions in Russia and Africa at Dell Technologies.

Carbon footprint reductions achieved with the proof of concept design are attributed to motherboard components with 75% smaller area and relocated to the top cover. This places the motherboard closer to a larger surface area exposed to cooler external air, improving passive heat distribution and potentially eliminating the use of a fan. Component count is reduced by 20% and overall power needs could be supplied with a smaller battery equipped with advanced deep-cycle cells.
