Customer case:

Lahti Energia produces energy from waste efficiently and environmentally friendly

Aug 12, 2015

The world’s first power plant that runs solely on gasified recycled waste – on various types of industrial, commercial and building site waste as well as some household waste. In this way the plant boosts efficient and environmentally friendly energy production as well as reduces the use of fossil fuels significantly.

Lahti Energia's Kymijärvi II power plant utilizes hot gas filtering technology that is virtually unique on a global level, resulting in many new insights into the technology. Modifications in the technology and changes in operating methods based on these experiences have improved the performance and reliability of the plant.

Society today generates a huge amount of waste, and it should be harnessed. Waste that cannot be recycled should be used in energy production.”
Ismo Nopanen, Process Manager at Lahti Energia
