Your BioCNG project, engineered right from day one.
Compressed biogas (CBG / BioCNG) plants are capital-intensive, and most problems are decided long before construction starts: in the feedstock, the process design and the contracts. Bert Energy supports developers, investors and industrial companies with independent technical and project development consulting, from the first idea to stable operation.
40+ years
of experience in biogas technology and anaerobic digestion.
140+ plants
designed and built since 2012, for manure, food waste, energy crops and industrial residues.
Around 15 countries
with Bert plants, from Germany and Japan to India and Africa.
German engineering
using the best technologies from Europe and Japan, combined with a strong engineering and project team in India.
Where CBG projects go wrong
The BioCNG sector is growing fast, and with it the number of plants that never reach their design output. The causes are almost always the same, and almost all of them can be avoided in the planning phase.
- Feedstock: availability, quality and seasonality were overestimated, or the substrate was never tested.
- Pre-treatment: fibrous substrates such as napier grass, paddy straw or press mud need the right pre-treatment, otherwise gas yields stay far below expectations.
- Process design: digester, mixing, heating and gas upgrading are not matched to the actual substrate mix.
- Operation: feeding and monitoring are not controlled, and nobody notices the warning signs until gas production collapses.
Experience from real plants
Our advice does not come from textbooks. It comes from decades of building and operating biogas plants for very different substrates and climates, and from analysing plants that did not perform as planned.
Example: For an automotive manufacturer in Pakistan, Bert Energy analysed the pilot operation of a biogas plant, identified the causes of unstable gas production and defined the substrate strategy and pre-treatment requirements for the planned full-scale plant.
Lenders, investors and offtakers get a clear, technically sound assessment, so that decisions are based on facts instead of brochures.
