Cogeneration biogas plants for autonomous power supply
Modern cogeneration biogas plants generate electricity and heat through the utilization of waste from agricultural enterprises and urban sewage systems, landfills. This technology is gaining priority positions throughout Europe. Biogas is used as fuel for cogeneration plants.
Biogas occurs during the fermentation of organic substances such as slurry, manure, liquid manure fertilizer, plants, food waste. It occurs in nature everywhere where there is no access to oxygen. In fermenters and putrefactive towers as a result of anaerobic fermentation (anaerobic - without oxygen) biogas is formed.
If organic material is stored without air, then, when exposed to methane-binding bacteria, the biological process begins, in which gas is formed. This is biogas.
The chemical composition of biogas
| Substance | Chemical formula | Content, % |
|---|---|---|
| Methane | CH4 | 40—75 |
| Carbon dioxide | CO2 | 25—55 |
| Water vapor | Н2О | 0—10 |
| Nitrogen | N2 | <5 |
| Oxygen | O2 | <2 |
| Hydrogen | H2 | <1 |
| Hydrogen sulfide | H2S | <1 |
| Ammonia | NH3 | <1 |
Biogas, as a rule, is used in cogeneration plants based on a gas piston engine to generate heat and electricity.

The average operating time of one well is 15 years, the estimated payback period of the project is 4-5 years.
The advantages of biogas plants include:
- Independence from the state in the field of energy and energy supply.
- Saving money by switching to your biogas.
- Instead of the usual disposal of organic waste, energy is generated and nutrients are used.
- Improving the ecology of the enterprise where the project is being implemented.
- Making extra profit by generating “green” energy and reducing the level of harmful emissions into the atmosphere.
- Biogas sludge is more effective as a fertilizer than unfermented sludge.
- By increasing at least twice the amount of newest energies by 2010 and developing and spreading environmentally friendly technologies on the basis of biogas plants, the use of biogas also serves to support the goal of protecting the climate.
- Creating additional economic support: making money - producing environmentally friendly energy.
MADEK, together with its partners, can undertake the implementation of the entire project on autonomous energy supply based on biogas technologies, which includes:
- Preparation of a commercial proposal for the creation of a biogas plant.
- Preparation of a feasibility study (feasibility study) of the feasibility of creating and operating a biogas plant, which includes: the selection of technological modes of operation of a biogas plant; Development of a process flow diagram of a biogas plant; Selection of the necessary equipment and components to create the installation; Suggestions for biogas utilization and comparison of different options; Calculation of estimates of construction and installation works; Calculation of economic indicators and the payback period of the installation.
- Experimental confirmation of biogas formation in a laboratory biogas plant, laboratory studies of the quality of organic fertilizers obtained.
- Detailed design of a biogas plant, including an automation system.
- Supervision of non-standard equipment manufacturing.
- Purchase of equipment and components needed to create a biogas plant.
- Construction and installation of the installation.
- Launching and entering the technological mode of operation of a biogas plant.
- Personnel training and maintenance of a biogas plant.
