According to Hubbub's website in Bristol alone, picking up litter costs around £6 million and around 3,700 tonnes are collected every year.
As stated by the company a four-metre-high wave, made with 90kg of rubbish, is floating on Bristol Harbour outside the Arnolfini from November 2022 to January 2023. Furthermore Hubbub installed bins that glow in the dark and feature special effects, such as display of sound, when opened. Users are also engaged and able to win prizes for binning litter through a free app.
