With the processing and feeding of biogas into the natural gas network, you increase the utilization rate of the raw biogas considerably and thus increase the overall efficiency of your biogas plant.

When processing biogas to natural gas quality, PlanET relies on selected processes that are installed turnkey.
In doing so, the customer-specific requirements, as with all our biogas plants, are taken into account and the plant is precisely designed to work economically and efficiently.

  • RNG is flexible: New sales opportunities eg. B. in the heat and fuel market.
  • RNG uses the existing infrastructure: RNG can be efficiently transported to customers via the natural gas network.
  • RNG stabilizes the energy system: balancing fluctuating renewable energies z. B. wind, sun) via a demand-based power generation from RNG.

This is why the feed-in of RNG is suitable for new construction projects and re-powering projects. At the same time, very different business models make it possible to gain access to value added with RNG. PlanET advises you independently on the right process selection, develops the right business model for you and brings together strong project partners. 


The raw biogas initially contains between 48 and 65% methane (CH4) and 35 to 52% carbon dioxide (CO2) and small amounts of other trace gases, which are regarded as impurities. The methane is separated from the other components of the raw gas before being fed into the natural gas network. For the processing of biogas to natural gas quality (methane enrichment) different methods are available.

RNG – Sustainable Membrane Power

Among other things, PlanET offers the membrane process in Europe. To process the biogas, the principle of selective permeation is applied. For this purpose, the highly efficient SEPURAN® Green gas separation modules developed by Evonik Industries are used. The process thus guarantees our customers state-of-the-art cutting-edge technology: without the use of heat and chemicals, the process can be used with relatively low investment costs and short installation times in all performance classes.

Biogas Upgrading: An efficient future with RNG

If the investment in a treatment for a single biogas plant does not pay off, there is the possibility of collecting the raw biogas from several biogas plants and feeding it into the natural gas grid at a common point. This option is particularly interesting for municipalities that want to participate in value creation through decentralized energy generation and who are also planning the targeted expansion of cogeneration.
