Biogas plants

We set standards for building and improving the quality of biogas plants.

Our portfolio includes not only the development, planning and construction of biogas plants using various feedstock sources, but also close technical and biological support. With our engineering arm based in Abuja, Nigeria, we offer our customers innovative gas processing technologies for biomethane production and gas upgrading. With our financing division, we can invest in large-scale waste-to-energy projects based on long-term offtake agreements.

From entry-level models to the megawatt range, our plants are characterised by industry-proven quality standards, materials from selected manufacturers and reliability of all plant components in continuous operation.

Variety of input materials

In addition to the classic input materials such as grain, maize silage and liquid manure, our plants also utilise the more favourable raw-fibre-rich biomass and organic residues. The individual components and the different input materials have been field-tested in Consentis' own plants and have proven to be reliable, solid and efficient.

Mature process technology

In terms of process technology, CLEANTECH GERMANY's plants also demonstrate a high degree of stability and continuously high capacity utilisation. This is reflected in the long retention time of the substrates, the low digester load, the large fermenter volume and a correspondingly extensive gas storage.

With biogas plants for renewable raw materials, you effectively produce climate-friendly biogas. This reduces disposal costs and protects the environment at the same time.


Gas-fired power plants of all output categories have in common that they can be adjusted relatively quickly in terms of the output generated. The start-up time of a gas-fired power plant is also usually well under one hour. They are therefore even suitable for peak loads. They can be combined well with wind power.

The exhaust gases of the plants contain carbon dioxide (CO2) and are thus harmful to the climate. However, the specific emissions are much lower than those of coal-fired power plants - between about 400 g/kWh for combined cycle power plants and about 600 g/kWh for pure gas turbine power plants. Combined heat and power generation or the use of biogas can further improve the climate balance. Otherwise, certain nitrogen oxide emissions occur, which are strongly dependent on the type of construction and flue gas cleaning.
