For the final event associated with London 2026: Recipes for Building a Food Capital, architect, property developer and designer Arthur Kay (one of Forbesʼ 30 Under 30 2017) joined The Observer ethical living writer and broadcaster Lucy Siegle, to discuss the power of turning waste into something more useful. The talk started with a series of questions about bio-bean, Arthur Kay’s project which started in 2012 and turns used coffee grounds into energy. The conversation went on to demonstrate how the principles of this project have informed Kay’s latest venture Skyroom, an innovative architectural concept which utilises wasted roof space for affordable residential housing in central city locations designed for the key workers integral to the functioning of the city itself.
