Biorig

Our activity consists of the development and execution of biomethane production facilities. We design biomethane plants that meet the most stringent technical and safety standards and regulations, using a wide variety of technologies and organic waste. Biomethane contributes to the circular economy of waste, environmental sustainability and the economic development of local communities.

Our activity

Biomethane, renewable gas

Biomethane is a renewable fuel that can be injected into the gas grid, obtained from a biogas purification process called upgrading, which in turn is achieved from the anaerobic digestion of organic waste.

 

This gas is mainly composed of methane (CH4) and carbon dioxide (CO₂), in varying proportions depending on the composition of the source organic matter. To bring biomethane on par with natural gas, CO₂ and other compounds must be removed to increase the methane content to above 96%.

Waste recovery

The biogas and biomethane production process begins with the procurement of organic raw materials. In the case of the plants that Biorig plans to develop, these raw materials are mainly composed of waste from agricultural and livestock farming.

The aim is for the plants to be centres for the transformation of organic waste into green energy and to contribute to solving the problems of by-product management that currently exist in the primary sector of agriculture and livestock farming. Thanks to this waste management, emissions of methane and other greenhouse gases are reduced.

What is biomethane?

Biomethane is a renewable fuel that can be injected into the gas grid, obtained from the purification of biogas, which in turn is obtained from the anaerobic digestion of organic waste. It consists mainly of methane (CH4) and carbon dioxide (CO2), in varying proportions depending on the composition of the organic matter of origin.

Biomethane typically contains between 50% and 70% methane, and it is this component that is responsible for its fuel capacity. If biomethane is to be brought on par with natural gas, CO2 and other compounds must be removed to increase the methane content to above 96%.

Agricultural biofertilisers

Once anaerobic digestion takes place, the end product, called digestate, which has a high agrological potential, is valorised in our plants to generate high quality agricultural fertiliser for use on crop fields. This process contributes to the circular economy of organic waste.

Valorisation is an aerobic process, whereby the digestate is combined with organic structuring materials, resulting in an excellent fertiliser for agriculture.

From waste to green energy

The production of biomethane from waste is an energy recovery process based on the circular economy, ranging from the production and collection of organic waste to its injection into the gas grid as a gas of renewable origin.
