From practice
Sawmill generates electricity and heat from its wood waste for over 10 years!
Since 2014, sawmill owner Robert Christl has been operating a wood gasifer from Spanner Re². Wood chips are produced from the wood by-products generated in the sawmill, which are used as fuel for the wood gasifier and also sold. The wood gasifier supplies the company with its own energy and receives subsidies. The wood chips are dried directly on site using the waste heat from the plant – a closed, efficient energy cycle that pays off in many ways.
Wood gasifier with HeatBoost technology for complete residue utilisation
Our innovative HeatBoost-technology significantly increases energy efficiency and ensures complete conversion away from coal.
- Pure mineral ash instead of coal residues
- No storage or disposal of coal
- Maximum fuel utilisation
- Additional CO₂ savings
Advantages of using a Spanner Re² wood gasifier
for your sawmill operation
Take full control of your energy costs
Use your own wood waste. This will not only reduce your energy costs, but also protect you against price spikes and reliance on imported energy sources.
CO2-neutral heat for drying
Use the heat directly for your drying floors or as process heat.
Flexibility
Rapid load changes. Runs when you are producing – stands still when you are not. You can also integrate other renewable energy sources such as PV or battery storage into your energy concept.
Proven technology
There are over 1,100 wood gasification plants installed worldwide.
Our wood gasifiers are easy to operate, robust and clean. Our innovative HeatBooster technology ensures maximum energy yield and clean ash.
Eligible for subsidies
Take advantage of government subsidies and benefit twice: from low-cost electricity and subsidies in your state – we will be happy to advise you.
Full service supplier
We offer complete wood gas solutions with fuel dryers for maximum efficiency
We supply wood gasifiers that are perfectly suited to your energy requirements, as well as powerful fuel dryers that allow you to fully automate the drying of wood chips to the desired moisture content, eliminating any 'wet spots'. The dryers operate at low dust levels (an additional filter is available), have a compact design, and require minimal maintenance.

Frequently asked questions - Wood gasifiers in sawmills
What wood quality is required?
Our wood gasification plants can use wood chips, shredded wood chips, briquettes, or pellets. These can come from forest residues, sawmill by-products, processed roadside greenery, chipboard or MDF residues, waste wood, biogenic residues such as nut shells, kernels, or even plastic waste. You can find more information on our fuel page.
How does a Spanner Re² wood gasifier work?
Our biomass power plant consists of a wood gasifier unit and a combined heat and power plant (CHP). The wood gasifier produces clean gas from wood residues. This gas is converted into electricity in the combined heat and power plant. When a CHP plant is connected to convert the gas into electricity, this is referred to as combined heat and power (CHP). This process generates electricity and heat. Alternatively, the gas produced in the wood gasifier can also be used directly, e.g., in industrial thermal processes (known as direct gas utilization). This allows natural gas to be replaced in a sustainable manner.
Can wood gasification systems from Spanner Re² be used for off-grid operation?
Yes, off-grid operation is possible. Load management and integration with battery storage systems or other energy generators, such as photovoltaics, are also possible.
