Valmet Gasifier for biomass and waste
The CFB (circulating fluidized bed) gasification process works by partially combusting the biomass or waste at high temperatures using a controlled amount of air. The resulting product gas is a versatile energy carrier, which offers a range of benefits.
As a global leader in CFB gasification technologies and services, we offer gasification solutions to meet the needs of various power and process industry sectors. Each of these solutions generates energy from biomass and waste with high overall efficiency.

Positive impact on the environment
Reducing CO2 emissions is important – and doing it in an efficient and economically viable way is absolutely critical. From this perspective, gasification technologies are quite relevant as they enable partial or complete replacement of fossil fuels with renewable fuels.
Another advantage of waste gasification is that the process provides much better electrical efficiency compared with the direct combustion of waste materials. Also, materials that would otherwise have been disposed of, such as unclean plastic, paper, cardboard and wood, and other problematic waste, are used.
Easy boiler modification
It is easy to modify existing boilers or industrial kilns for the gasification process – even while leaving your existing fuel systems operational in parallel or for backup.
Modifying your operations for gasification creates a system that can accept many types of fuels. It can even be constructed on a scale of up to several hundred megawatts unit size. What’s more, modifying an existing plant can extend its lifetime significantly.

Customer success stories
Biomass gasification eliminates fossil fuels in the pulp mill
Valmet delivered two biomass gasifiers to OKI Pulp & Paper Mills' pulp mill project in South Sumatra, Indonesia. The gasifiers utilize circulating fluidized bed (CFB) technology and their capacity is 110 MW each.
Fuel conversion for power boilers: Vaskiluodon Voima Oy, Vaasa, Finland
Valmet Gasifier for Vaskiluodon Voima Oy was built in response to the critical need to reduce the environmental load of traditional coal-fired power plant.
Highest electrical efficiency from waste: Lahti Energia, Lahti Finland
Lahti Energy’s Kymijärvi II power plant, the world’s first eco-gas fueled power plant, was inaugurated in 2012. The power plant runs on SRF that is gasified, cooled and cleaned before combustion and produces 50 MW of electricity and 90 MW of district heat for the city of Lahti in Finland.
Valmet-supplied gasification plant inaugurated at Göteborg Energi's GoBiGas in Sweden
The Valmet-supplied gasification plant at GoBiGas (Gothenburg Biomass Gasification Project) was inaugurated on March 12, 2014 in Gothenburg.
Gasification of sorted waste reduces the consumption of fossil fuels
The gasification-based plant developed by Valmet, which operates at Lahti Energia's Kymijärvi II power plant has been in commercial use for more than 25 000 hours.
Metsä Group Äänekoski - Bioproduct mill
Valmet’s delivery to Metsä Group's Äänekoski Bioproduct mill included a recovery boiler, pulp drying line, gasification plant, lime kiln, sulfuric acid plant, and mill-wide Valmet DNA automation system.
Biomass gasifier reduces emissions at Vaskiluodon Voima
The integration of a biomass gasifier with an existing coal-fired boiler has enabled Vaskiluodon Voima’s power plant in Finland to increase the use of renewable fuels.
Environment and economy shaking hands
The EU’s circular economy, greater energy self-sufficiency and promoting energy and climate goals are placing greater demands on today’s society. New power generation technology makes it possible to balance environmental compliance with economic performance.
