Vantaa Energy's new waste-to-energy plant in Vantaa, Finland is the largest and most energy-efficient in the country. The plant processes 1,400 tons of mixed waste daily, generating 920 gigawatt-hours of district heat and 600 gigawatt-hours of electricity annually. More than 200 Vacon AC drives control pumps, fans, and conveyors to optimize energy efficiency and reduce fossil fuel usage and carbon emissions. The plant director stated that the waste-to-energy facility is a major environmental achievement for mitigating climate change.

ENERGY-EFFICIENT WASTE-TO-ENERGY PLANT
KEY FACTS:
• Inaugurated in September 2014, Vantaa Energy’s new waste
to-energy plant is Finland’s largest and most energy-efficient
waste-to-energy plant.
• Every ordinary working day, Monday to Friday, 1,400 tons of
mixed waste - collected mainly from households in the
Helsinki region and surrounding areas - are delivered to the
plant. Annually this amounts to 320,000 tonnes of waste.
• Over 95 per cent of the energy in the mixed waste can be
converted into district heat and electricity, in total 920
gigawatt-hours (GWh) of district heat and 600 GWH of
electricity a year.
