Engieering, construction and start-up of a commercial methanogenesis plant for the production of synthetic diamonds (UK)        

Commercialization of an innovative adsorber technology for NOx removal in industrial scale   


Engineering, construction and operation of a NOx capturing facility in an urban area.


Gas purification platform for wide treatment of small/large emission gases and air.

Successful participation in 2 EU funded projects, Celbicon ( and Engicoin ( using biochemical core competence for methanogenesis but also acetone production.


New facilities for integrated process development established west of Vienna. Here we focus on the development of closed C- and N-cycles


Krajete Process licenses to first 2 customers.
Krajete GmbH becomes a viable partner in 2 substantial projects on EU (“Celbicon”, Horizon 2020 call) and national (“BioHyMe”) level. Strong focus on process expansion beyond methanogenesis (e.g. gas purification up-/downstream).
Gas Purification beyond CO2 to NO and NO2 removal.


Expansion to other C and H sources via gasification and pyrolysis with the intention to save electrolyzer and electricity costs.
Exhaust gas purification established with industrial CO2 soures in laboratory. Focus on solid adsorbers.


Further process improvement through optimized media composition to reduce operating cost. The process development is reflected in 4 patent applications. “Krajete® Process“ becomes a brand name. First candidates for licensing. Diversification of the full process by adopting complementary technologies. Methanogenesis employed for other carbon sources than CO2.

Exhaust gas purification established in laboratory scale with the intention to enrich CO2.


Krajete GmbH becomes a pioneer in process development of methanogenesis.


Limited Liability Company formation and further process development with industrial gases. Key arguments from 2007 verified. The process unveils its full potential through robustness, adaptation, conversion and simplicity.


A third grant by Austrian „FFG“ awarded. Individual enterprise established. First customers and different perception of the technology`s potential triggered by a) Fukushima, b) Arabic Spring, c) German Abandoning of Nuclear Power


Selection of a robust microrganism. Process development with pure gases in 10 L scale.


First grant by Upper Austrian start-up incubator „tech2b“ followed by a second grant by „AWS”, preseed funding. Start of process development at Technical University of Vienna in 1 L scale.


Inspiration to develop a biological process for CO2 utilization. Motivation is derived “from waste to energy”. The process should have the potential to process CO2 in kiloton scale and beyond.
