Biomacon is a family business based in Rehburg near Hanover. The company was founded in 2009 by Ulrich Suer and was started out of the desire to make an effective contribution to combating climate change. Our pyrolysis boilers produce regenerative heat from dry biofuels and store CO2 in form of high-quality biochar. Since the beginning, the focus has been on building energy-efficient systems that compete in the same class as conventional heating systems with nominal heat power below 500kW (fuel power below 1MW), in order to be able to replace them in the medium term. Since 2023, we have more than 30 pyrolysis boilers in operation throughout Europe, with a focus on Scandinavia and Switzerland. Many of our customers have their plants EBC-certified and produce high quality biochar. With an international team and manufacturing partners in Turkey, Germany and Sweden, we are scaling our production capacity to meet the challenges of tomorrow.


Our design criteria for the Biomacon pyrolysis boilers are a robust process structure, simple operation and efficient heat utilisation. For this purpose, the systems were developed according to the requirement, DIN EN 303-5 for biogenic solid fuel boilers with a nominal heat power smaller than 500kW. Therefore, in most cases, only the 1st BImSchV (building permit) is required for approval. Keep it simple. Biomacon pyrolysis boilers are currently the only pyrolysis systems that can be used in medium-sized heating centrals in residential and commercial sectors and are comparable with conventional boiler systems. The daily operating time is approx. 1-2 hours (incl. filling the boiler and replacing the biochar).

Plant size

The pyrolysis boilers are built in two different classes: 1) Edition F with a nominal thermal output of 160kW to 224kW, a biochar production capacity of 18 to 27 kg/h and a floor space requirement of 18m2 to 32m2; 2) Edition I with a nominal thermal output of 224 kW to 500 kW, a biochar production capacity of 27 to 58 kg/h and a floor space requirement of 35 m2 to 45 m2
