SFW becomes a strategic investor in WOIMA, combining SFW’s renowned expertise in power technology, project execution, and global reach with WOIMA’s innovative plant design.


Espoo, Vaasa, January 13, 2021. – The wasteWOIMA® plant is a unique solution to address the challenge of growing municipal waste and environmental issues associated with landfilling. It fits perfectly for small and medium-size cities with local waste management and energy generation.

The plant utilizes robust grate combustion technology to safely treat a wide range of solid wastes while complying with the most stringent environmental standards. It is designed to serve a waste collection area of 100,000-500,000 people and convert from 30,000 up to 200,000 tons of non-recyclable waste annually into renewable electricity and heating or cooling.
