Bert Panel Fermenter with Mira Carbon
The next generation of modular biogas technology.
Transforming all kinds of biomass, from food and kitchen waste to slurry, manure, straw and sewage sludge, into renewable energy and valuable fertiliser. Bert Energy combines long-standing experience in anaerobic digestion with modular construction and a robot-supported approach to plant assembly and ROBO operations.
Organic waste is a valuable resource.
Different substrates need different pretreatment, digestion strategies and energy concepts. Bert starts with the feedstock and builds the right technical solution around it.
Food waste
Food processing residues, commercial and flight kitchens, bakeries, supermarkets, hotels and municipal organics.
Animal substrates
Cattle, pig and poultry manure and slurry and other animal residues, with substrate-specific process design.
Other organic residues
Straw, grass, agricultural residues, fibrous materials and suitable industrial organic by-products.
Every substrate has a different gas yield
Approx. m³ biogas per tonne of fresh matter · DM = dry matter · right: ≈ kW electrical continuous output at 1 t/day. Click a substrate to use it in the calculator.

| Substrate | Dry matter (DM) | m³ biogas per t | ≈ kW el. at 1 t/day |
|---|---|---|---|
| Used frying oil | 95 % | 700 | 67 |
| Waste bread | 70 % | 500 | 48 |
| Straw | 86 % | 400 | 38 |
| Corn silage | 35 % | 210 | 20 |
| Grass silage | 40 % | 190 | 18 |
| Chicken dung | 40 % | 187 | 18 |
| Intestines | 30 % | 185 | 18 |
| Blood | 19 % | 150 | 14 |
| Cow dung | 25 % | 105 | 10 |
| Brewery grain | 20 % | 100 | 10 |
| Kitchen waste | 12 % | 95 | 9 |
| Sewage sludge | 8 % | 48 | 5 |
| Whey | 6 % | 43 | 4 |
| Cow slurry | 8 % | 28 | 3 |
| Pig slurry | 6 % | 18 | 2 |
1 tonne of substrate per day yields approx. 2 kW to 67 kW of continuous electrical power. Substrates and substrate mixtures are the key factor for energy output and payback period. Not all substrates can be mixed or used 100 % alone.
Typical average values; actual yields vary with substrate quality, organic DM content and retention time. kW el. based on 6 kWh/m³ biogas and 38 % CHP efficiency.
What can your substrate produce?
Choose a substrate and the daily amount for a quick first estimate of biogas, LPG equivalent and electricity. Add your local prices to see what your waste is worth in your currency.
Enter your local prices to see the value of your waste. LPG and electricity are alternative uses of the same biogas, so the two values are not added up. Typical average values for a first orientation. A detailed calculator with more substrates follows. For a project-specific calculation, ask Bert or contact us.
This is just a first glance of the value you have from your waste, but there are many other waste income streams.

From organic waste to renewable energy.
Substrates move through pretreatment, anaerobic digestion and gas treatment into energy use, while digestate becomes a second value stream.
What biogas can do
How household waste, manure and sewage sludge become renewable gas, energy and fertiliser, explained in under 90 seconds.

Feed tank, digester, gas storage, gas cleaning, energy use and digestate separation in one compact layout. Click to enlarge.
Industrialised construction meets robotic innovation.
The Bert Panel Fermenter is built from standardised panels. A robot helps with unloading and assembly. Click either image to play the original footage.
Transport & unloading
The robot receives and handles the panel components.
Assembly
Panel-by-panel installation for fast, repeatable construction.
Operation and maintenance support by robot is a future development and not yet part of current plants.
One renewable energy source. Many possibilities.
Biogas can be matched with different local applications. The right energy concept depends on demand, infrastructure and economics.
Continuous production needs smart utilisation
Illustrative day profile: a biogas plant produces steadily around the clock, while energy demand changes. Hover for hourly values.
Because large gas storage is usually uneconomic, Bert designs the energy concept around continuous use: combining consumers such as CHP, cooking, cooling and fuel so that the gas is used when it is produced.
Valuable fertiliser. Not just a by-product.
Digestate is the second output of the biogas process and a value stream in its own right. Further nutrient recovery can create additional value.
Liquid fertiliser
Liquid digestate delivers nutrients for agricultural use, depending on quality and local requirements.
Solid fertiliser
Separated solids can be used in organic fertiliser and soil-improvement concepts.
Built on experience. Proven in operation.
Start your market with one container.
The 100 kg/day food-waste plant is a complete, fully containerised and mobile biogas plant. For new franchise partners it is the ideal way to open a market.
- Show it working: clients see the whole biogas process live, from food waste to gas and fertiliser.
- Move it: the container goes to fairs, hotels, campuses and pilot sites.
- Scale up: from the demonstrator to MiraX and full-size Bert plants.
Demonstrate
100 kg/day container plant as showcase and first reference.
Containerised
MiraX container plants for larger volumes of organic waste.
Farm and food industry
Bert plants for food waste, manure, straw and other substrates.
Industrial
Large digesters with CHP, e.g. 800 m³ / 100 kW in Japan.
Why Bert works with local partners
Every country has its own rules for permits, imports and grid or gas connections, and its own language. A biogas plant needs a supplier who knows all of this and is close to the customer. That is why Bert sells through franchise partners instead of shipping plants anonymously around the world.
What a Bert partner does
- Develops the market and is the customer's first contact, in the local language
- Obtains planning and construction permits under local regulations
- Imports, installs and commissions the plants
- Provides service and maintenance on site
Business models
Depending on the market, projects can be structured as a direct plant purchase or as partner-led BOOT / Biogas-as-a-Service models with an O&M contract. For suitable project portfolios, Bert and its partners can also help evaluate carbon-credit opportunities.
What Bert provides
Becoming a Bert partner starts with an in-depth training programme. After that, Bert Energy and its partners such as Kankyo Bert stay at your side. The franchise contract is your guarantee that you can always rely on our know-how and service, today and for every plant you build in the future.
- Technology licence and the Bert brand
- Training in sales, engineering and service
- Territory protection for your market
- Engineering support for design and sizing from Germany
