Leeds City Council announced on Tuesday 17 March that the first 800 households have been connected to the city’s £36mn ‘Leeds PIPES’ district heating network, which uses heat generated from black bin waste. After the scheme’s first phase is completed later this year, nearly 2,000 connected households are estimated to save 10-25% on annual energy bills. It is expected to reduce the city’s annual carbon footprint by 11,000 tonnes.
