SmartSheffield #18 - Martha Hart: "Leeds District Heating Network, How waste and data can help us decarbonise our heating"

Martha is an Associate Energy Consultant at Arup in Sheffield, and has been instrumental in the development of the new district heating network in Leeds. Here she reviews her experience of designing the new facility and explains how waste and data need to work together to optimise waste and energy recovery systems to help decarbonise cities.
