Without energy there is no life

The ever increasing consumption of energy is today the most serious threat to life. In the EU, energy consumption accounts for 80% of greenhouse emissions which are considered to be the main cause of climate change. Reducing CO₂ levels in the atmosphere has become a global objective which an increasing number of states are working together to achieve. Growing, unstable prices and an insecure supply represent an ever increasing risk due to energy dependency on oil and natural gas. The dizzying growth of energy consumption on the one hand and the reduction of fossil fuel supply on the other have become the greatest problems of modern times. Concern for the future led to research of renewable energy sources, which in turn led to developing new, more efficient and more environmentally friendly technological procedures for clean energy production.

Why biogas?

Production of “green energy” from biogas, which is a renewable energy source, is a promising and environmentally less harmful method of energy production, as it reduces CO₂ emissions into the environment as well as reducing the energy dependency on imported energy sources. As the construction of a biogas power plant concludes the natural cycle: food – farming/breeding – processing – biogas – field – food, it also contributes to rural development.

Is there a better solution? There is! Biogas.

Biogas is a mixture of gasses that is produced during anaerobic fermentation of organic matter. Fermentation of horse and cow manure, liquid manure, energy crops, slaughterhouse waste and other organic waste is done with the help of microorganisms like bacteria and mould. The breakdown of biomass and animal waste proceeds in the absence of oxygen in a closed container, called a fermentor or a fermentation container. Biogas is composed of 50-70% methane, 25-50% CO₂ and a mixture of hydrogen, nitrogen, ammoniac, hydrogen sulphide, carbon monoxide and vapour. Biogas is thus one of the most efficient fuels with a beneficial impact on the environment, as it does not contribute to increasing the greenhouse gas levels in the atmosphere.

Sources of biogas

Biogas production represents one of the options for efficient processing of organic waste. Biogas can be obtained from almost any organic material containing a sufficient share of carbon and from all organic biological matter whose structure changes due to microorganism activity.

Biogas production

A typical biogas production system is composed of the following elements:

1. Collecting the excrements of bred animalManure is collected in form of liquid manure, excretions, in half-solid or solid form.
2. Anaerobic fermentorFermentor is an airtight and watertight container where biogas is produced and stored. It represents the most important part of gas production and the choice of fermentors depends on the planned or the existing manure collection system.
3. Collecting the sludgeThe products of anaerobic fermentation of substrates in the reactor are biogas and sludge. Sludge is mostly made up of water, not fully decomposed cellulose, lignin and minerals. Sludge is a rich live organic fertilizer, which does not only return minerals to the soil, but microorganisms as well.
4. Gas pipesThe system for transporting gas from the fermentor to the gas reservoir and from there to the place of use, e.g. to motors and boilers, includes: pipes, a gas pump, a gas flow meter, a pressure regulator, a condensate outlet and in certain cases a filter for removing sulphur from biogas.

How to estimate your sources for biogas production?

For a rough estimate of the quantity of biogas you can produce based on the number and the type of livestock you breed, you may use the table below, but we strongly suggest that you contact one of our experts working at Organica, who will be able to precisely calculate and help you select the optimal solution.

Livestock type	Animal weight (Kg)	Biogas production (m³ / animal per day)
Cattle	350 - 400	0,45 – 1,0
Pigs	80 - 100	0,116 – 0,2
Sheep	30 - 40	0,06 – 0,07
Poultry	1,5 - 2	0,0035 – 0,004
