Waste from Notting Hill Carnival has been used to generate green energy.
The event, which attracted more than one million people over the weekend, saw 200 tonnes of rubbish generated over two days in Westminster.
The clean-up operation by Westminster City Council, in partnership with Veolia, used 170 staff and 30 vehicles.
Ten tonnes of waste were recycled while the remainder was converted to energy, sent to the National Grid and used to power and heat London homes.
It is estimated around 20,000kWh of heat and 100,000kWh of electricity was produced – enough for 800,000 hot showers or 700,000 cups of tea.
