Biogas plants on pig farms

We design and implement biogas plants in Ukraine, taking into account the specifics of pig farms, types of manure removal and characteristics of raw materials. We guarantee efficient biogas production, reduced emissions and compliance with environmental requirements.

Without a biogas plant:

  • Fixed costs for manure removal and disposal.
  • Spreading unpleasant odours around the farm.
  • Risk of soil and water contamination.
  • Decreased attractiveness of the property for investors.
  • Dependence on the energy market and tariffs.

With BSU, you get:

  • A source of energy and profit from waste.
  • Odour reduction and environmental benefits.
  • Compliance with EU standards.
  • Investing in biogas plants.
  • Energy independence and predictable costs.

About raw materials

Pig manure is a promising raw material for biogas production, but its effective use directly depends on the manure removal system. The best option is a self-flowing system with minimal water addition (1:1): manure accumulates in sealed tanks and retains high gas potential. This is the standard for modern farms.

Hydraulic washing (1:10) significantly reduces the concentration of organic matter, increases the volume of reactors and calls into question the economic feasibility of the project. Cold storage on deep litter has good potential for biogas production, but the manure removal system itself, which operates once a month, is not adapted to the daily supply of raw materials required by a biogas plant, and the raw materials require additional special processing (in particular, grinding), which makes the project more expensive.

To increase efficiency, we recommend adding co-substrates (silage, distiller’s grains, pomace) to liquid manure — this allows you to increase the organic load and biogas yield, improve the energy balance and make the installation more cost-effective.

Special attention should be paid to the storage of raw materials. If manure accumulates in open lagoons or mixes with large amounts of wastewater, a significant portion of its methane potential is lost. Proper sealing, minimising oxygen access and optimal storage time are critical to maintaining high gas production levels.

Biogas technologies for pig farms

Pig farms are real growth points for biogas plants in Ukraine. Since pig manure is very liquid and has a relatively low concentration of organic matter, we design agricultural-type CSTR reactors with membrane gas holders and optimise the process by adding co-substrates — silage, distiller’s grains, and litter.

Depending on the method of manure removal, partial pre-treatment is applied: pre-treatment (if manure is on coarse bedding), grinding, heating during the cold season, mixing in buffer tanks. Manure separation is carried out only if it needs to be pumped through pipelines over long distances, but if the farm and the biogas plant are located nearby, there is no need to separate manure on the farm. Homogenisation of liquid manure takes place directly in the reactors.

The quality of biogas depends on feed: high protein = more H₂S. Up to 1000 ppm, we use activated carbon filters, above that — biological scrubbers. Upgrading to biomethane requires drying and removal of siloxanes. When using mixed raw materials (e.g. chicken manure + pig manure or slurry), a combined purification system is selected.

The optimal strategy is to combine upgrading with cogeneration (CHP), which allows you to create a single energy system for the complex and the farm supplying raw materials. This guarantees the energy independence of the biogas complex. In addition, SCADA and commercial accounting systems are being implemented: from raw materials to biomethane — everything is under control.

    Frequently asked questions

    Can manure with straw or sawdust be used in a biogas plant?

    Yes, biogas can be produced from manure with bedding, but for effective fermentation, the straw must be pre-shredded. We design biogas plants that take into account these characteristics of the raw materials. This allows for a stable supply of biogas.

    What to do if manure is washed away by water?

    When manure is washed away by water, the raw material is diluted, which increases the volume of the reactor and heat consumption. We adapt the biogas plant to these conditions: the design includes large-capacity tanks and additional heat exchangers to ensure reliable biogas production from cattle manure. We also recommend the use of co-substrates to ensure efficient use of the fermenter volume.

    How much biogas can be obtained from 1 tonne of cattle manure?

    On average, 20-80 m³ of biogas can be obtained from 1 tonne of manure without bedding. The output is influenced by moisture content, storage method and animal diet. This level of biogas production makes biogas plants economically viable even for medium-sized farms.

    What fertilisers are produced after biogas production from valuable organic fertiliser?

    After fermentation, digestate is produced — a valuable fertiliser used in agriculture. This reduces the cost of mineral fertilisers and reduces the carbon footprint. A biogas plant converts waste into energy and fertiliser.

    Is it profitable to use biogas for farm energy supply?

    Yes, the use of biogas allows farms to become energy independent. Biogas plants in Ukraine already provide farms with heat and electricity. This is especially relevant for cattle complexes, where a stable energy supply is critically important.

    Can surplus energy from a biogas plant be sold?

    Yes, biogas production allows electricity to be sold to external users. A biogas plant can operate as a mini power plant. This is common practice — biogas plants in Ukraine have already been implemented using this model.

    Is it possible to build a plant for producing biomethane from manure?

    Yes, we are implementing biogas plants that involve purifying biogas into biomethane. Such biomethane can be exported to the EU — we take certification requirements into account. This opens up a new market for farmers and increases the profitability of biogas from manure.

    How much does a biogas plant for a cattle farm cost?

    The price depends on the capacity, type of reactor, and method of manure collection. The cost of small biogas plants starts at €500,000, and medium-sized plants start at €2 million. We offer individual calculations and help you choose a biogas plant for your specific needs.
