biogas becomes biomethane

With our agriPure®, biogas is upgraded to biomethane. From the biogas plant to biogas pre-treatment to biogas / CO2 processing and upgrading to BioLNG or BioCNG.


From Biogas to Biomethane

a perfect system

The innovative and sustainable agriPure® biogas upgrading plant was originally developed by agriKomp in 2015.

The biogas upgrading process converts biogas produced by anaerobic digestion into biomethane using special membranes. There are several pre-treatment steps to clean and condition the biogas. The biogas is then compressed before entering the membranes which are used to separate the methane (CH4) and carbon dioxide (CO2) gases at a molecular level. After this upgrading process, the product biomethane can be sent to the gas grid or further compressed or liquefied for use as transport fuel.

In general, biomethane can be used after biogas upgrading wherever natural gas is also used. Both variants are chemically equivalent and differ only in their either fossil or biogenic origin. This opens up a wide range of possible applications.


With agriPure®, we offer a complete solution for anaerobic digestion and biogas upgrading: From the biogas plant and biogas pre-treatment to biogas upgrading / CO2-recovery and liquefaction and finally processing biomethane into BioLNG or BioCNG – agriKomp is the right partner for your project.

Our service network is well established and international with experienced service engineers and good spare parts availability. Your agriPure® plant will receive a well-coordinated and reliable service support, providing the best opportunity for a long and trouble-free plant lifespan.

agriPure® is available in a broad capacity range from 135 Nm3/h to 2,000 Nm3/h of raw biogas for small farms or even associations of farmers. Thanks to the high flexibility of the process developed by agriKomp, the membrane technology can be adapted very easily to changing volume flows and gas compositions.

Our biogas treatment agriPure® received a major update. The new agriPure® CUBE creates new possibilities in the area of flexibility, modularity and profitability. The new modular design allows the system to be adapted to all conditions. The clever linking of individual processes ensures higher efficiency and complete scalability of the entire system. The unique modularity and flexibility enable uncomplicated and cost-effective adaption of the system even after commissioning.

Performance remains a priority with the agriPure®: with a methane output of over 99.4 % and excellent energy efficiency, our agriPure® gas treatment is very profitable. Standardised components ensure easy operation and maintenance. 

A Rubik‘s Cube inspired us to name it „Cube“ because the many cleverly adapted and linked modules and processes make a perfect big picture.
