Meanwhile in the UK, our Renescience waste-to-energy plant uses household waste to produce electricity and materials that can be used in manufacturing, construction, and land restoration.
Read on to find out more details about each of these plants.

Converted from coal to sustainable wood pellets, Studstrup heat and power plant is one of the largest biomass-fuelled power stations in the world, providing enough power and heat for hundreds of thousands of Danish homes.
Location: Nordhavn, Copenhagen
Heat-generating capacity: 256 MJ/s
Fuel: Natural gas
In operation since: 1953
Converted from coal into oil and gas in 1994, and to gas alone in 2014
Originally built to supplement heat and power production at H.C. Ørsted CHP on the other side of central Copenhagen, Svanemølle is now a heat plant which supplies around 6000 homes with district heating.
Location: Hornsherred, Zealand
Power-generating capacity: 734 MW
Fuels: Diesel, natural gas
In operation since: 1940
Kyndby power station provides emergency and peak-load electricity for the island of Zealand. That means it can be started up within minutes if there are problems elsewhere in the grid.
