In the Vale, residents can use their food waste caddies to recycle food waste at the kerbside. The collected food waste gets processed and taken to Welsh Water Organic Energy food waste site in Cardiff. Welsh Water take organic waste from both the Vale of Glamorgan Council and Cardiff Council. The food waste is processed through anaerobic digestion, a process where microorganisms break down organic matter, producing biogas which is used to generate green energy: 715 caddies of food waste would create enough green energy to light up the Principality Stadium floodlights for an entire game You could keep your phone fully charged all weekend with just 2 banana peels A caddy full of food waste would produce enough green energy to watch two hours of your favourite TV series
