Centre for Biomass Technology publishes information obtained through the daily work and research and development projects. The fact sheets are distributed to the subscribers: Danish district heating plants using biomass as fuel, boiler manufacturers, biomass producers etc.

The fact sheets are in Danish. However, Centre for Biomass Technology has translated a few of the fact sheets into English. The fact sheets presently available in English are marked (UK) in the following complete list of fact sheets. Upon request further translations can be performed by our translator based on the actual cost of this task. For orders of fact sheets and enquiries for further translations, please go to the contact form.

The English titles of the Danish fact sheets are:
