We as Biogas-Ost offer our customers reliable, efficient, and customised biogas plants. We have specialised in so-called Clever-Ferm-Systems with an electrical power range of 30 to about 150 kW as well as in systems with substrates which are difficult to ferment, e.g. slaughterhouse waste, glycerol, manure, hay, straw and residues from olive oil production.

Working very closely with you as our customer, every system is specially tailored to meet your specific individual ideas and local requirements. For this, our experienced and qualified staff assists you from the planning phase through the system construction and to the commissioning start-up phase.

The planning and design of each biogas system is internally based on our over 20 years of experience in this area. If you would like us to offer you a biogas plant, please fill in the inquiry forminquiry form to as much detail as possible, because your data represents the basis for the optimal design of your plant. Changes in plant design and construction are possible at any time in compliance with local regulations and laws. In addition, for our German customers we offer to take over the approval process as well as all the necessary communication with the authorities.

All of our biogas plants process substrates by so-called wet fermentation. During this process, all substrates are pumped into the digester continuously, mixed by agitators, while the heating system, fixed inside the tank, heats them up.
According to your wish, the digesters can be made of wood, steel or concrete, and are standardly equipped with double membrane air-supported roofs.

There are two final outputs of the digestion process in a biogas plant, an energetically usable gas produced by fermenting the substrates on the one hand, and the fully fermented product representing a high quality and biological fertiliser, on the other hand,.

Single-stage biogas plants suite especially well for the fermentation of liquids and substrates with low dry substance-concentration and a long dwell period.

Multi-stage biogas plants are best suited for digestion of liquids and substrates with low dry substance-concentration as well as for the application of renewable primary products. Depending on the plant design, the digesters can either be charged parallel or consecutively with the circulatory principle.

The entire process is identical for biogas plants of all sizes. A small proportion of the electrical and thermal energy produced by the CHP is used for the self-sufficiency of the system. The majority of thermal energy can be used for heating residential or commercial buildings, and greenhouses  or can be fed into the public grid. The largest scale of electrical energy can be either used for decentral energy supply or sold to energy supply companies.

The company's own assembly department ensures that your planned project will be implemented reliably.

After planning and construction, we will also assist you during the start-up phase of your biogas system. We offer commissioning, training of the plant personnel as well as advice on technical and biological level.

To find the right funding for the system is generally seen as challenging by many customers. From our experience, the cooperation is uncomplicated between most of the house banks and the proposer. There is also the possibility of export credits for most European countries. We can help you to prepare the necessary documents and assist you on all required steps.

Biogas is produced by anaerobic (oxygen-free) digestion of biomass. As an input medium, also known as substrates, almost all organic masses are suitable, e.g. manure, sewage sludge, organic waste and dedicated energy crops.

In addition to the above mentioned substances, biogas can also be produced from residues that occur in counties, cities, and towns (such as grass clippings, food waste and by-products of food production).

The substrates are pumped into heated and insulated digesters in which they will be fermented at temperatures between 40° and 45° C. Bacteria produce a gas which contains methane by decomposing the biomass. This gas can be used as fuel for cogeneration plants (CHP) to generate electricity and thermal power.

The power can be fed into the public grid while the heat may be used for heating purposes in buildings (such as housing, hospitals and greenhouses) and other process operations (such as steam and drying).

The digestates will be pumped into appropriate storages and represent a high-value natural fertiliser.
