Google Unveils Eco-Focused Gemini Home Speaker with 3D-Knit Enclosure

Google announced the Gemini Home Speaker, its latest smart speaker, highlighting a redesign that reduces adhesive and increases recycled content, aligning with its broader environmental strategy.

Earlier models such as the Nest Mini used fabric bonded with adhesive, while the Nest Audio employed a conventional plastic shell. Google’s sustainability roadmap calls for more recycled material use and lower manufacturing waste.

The Gemini speaker features a “tensioned 3D-knit enclosure fabric wrapped over a plastic housing without any adhesive.” The fabric, composed of recycled polyester and spandex yarn, can be partially stretched when handling the device. This construction enables “manufacturing rework”: if a defect occurs in either the fabric or the plastic housing, the unaffected component can be reused, lowering material yield waste and cost.

Inside the speaker, a quad-core Cortex-A55 processor (2.0 GHz), an on-board NPU, 1 GB LPDDR4 RAM, and 4 GB eMMC storage drive audio processing. The unit ships with a 30 W USB-C power adapter that “meets DOE Level VI, the highest available efficiency rating for power adapters as defined in the International Efficiency Marking Protocol for External Power Supplies Version 3.0.”

Google’s Recycled Materials Guide states that the new enclosure “eliminates adhesive” and that the speaker “uses at least 37 % recycled materials.” The Product Environmental Report highlights the 63 % material reduction and 99 % adhesive reduction as measurable progress toward the company’s zero-waste objectives. Google also notes that the power adapter’s DOE Level VI rating aligns with its commitment to energy-efficient accessories.

The 9to5Google review observes that “it would have been nice if the USB-C cable was not permanently attached to the Home Speaker,” suggesting a limitation for users who wish to replace the cable or perform repairs.

Google plans to release updated environmental reports for its hardware lineup later in 2026, potentially addressing repairability feedback such as detachable power cables. Continued monitoring of material sourcing and adhesive use will inform subsequent product generations.
