Prince William visited Bristol to meet Matter, a 2025 Earthshot Prize finalist, showcasing its innovative filtration technology designed to prevent microplastics from entering waterways. The Prince has installed the £199 Matter unit in his residences and aims for its adoption across royal households.

During the visit, he engaged with Matter's CEO Adam Root about global expansion plans. William also toured the University of Bristol to see Isambard-AI, the UK's most powerful supercomputer, capable of processing data at unprecedented speeds.

Scientists at the university are leveraging Isambard-AI for drug development targeting heart disease, Alzheimer's, and cancer, as well as predicting extreme weather. The visit highlights Bristol's achievements in sustainability and innovation. Additionally, Kensington Palace announced William's upcoming official visit to Saudi Arabia from February 9 to 11, 2026.
