Biomethane is a renewable gas produced from organic materials such as agricultural waste, plant residues, household waste or other biodegradable materials (so-called biomass). It is mostly composed of methane (CH4) and has similar properties to natural gas. Therefore, biomethane can be used as an environmentally friendly alternative to fossil fuels to generate energy and reduce greenhouse gas emissions.

Biomethane is usually produced by two main processes: Fermentation and gasification.

1. Fermentation (Anaerobic Fermentation): In this process, organic materials are broken down by microorganisms in the absence of oxygen. This produces what is known as biogas, which consists mainly of methane and carbon dioxide. The raw biogas is then purified and upgraded in several steps to remove impurities such as hydrogen sulfide, ammonia or carbon dioxide. The resulting product is the high-quality biomethane, which can be fed into the natural gas grid or used as fuel.
2. Gasification: In gasification, the organic materials are converted at high temperatures into a gaseous mixture of hydrogen, carbon monoxide and methane. These synthesis gases are then converted into methane in a methanation process. Further purification steps separate the methane from other gases and yield the pure biomethane.

Biomethane can be used to generate electricity, heat or as a fuel in mobility. It helps reduce greenhouse gas emissions and supports the energy transition toward renewable energies.

Bio-LNG (Liquified Natural Gas) which means "bio-liquefied natural gas" is a form of renewable liquid biogas produced from renewable resources.These are organic materials such as agricultural and vegetable waste, food waste or animal excrement. Bio-LNG is produced by fermenting these materials in a digester. This produces biogas, which consists mainly of methane and carbon dioxide. The biogas is then further purified and upgraded to increase the methane content and remove impurities. Finally, the methane is cooled to extremely low temperatures (about -162 degrees Celsius) for storage and transportation in liquid form. This process makes the gas about 600 times smaller than in its gaseous state, making transportation and storage easier and more efficient.

Bio-LNG is an environmentally friendly alternative to fossil fuels such as crude oil or natural gas, as it is produced from renewable raw materials and releases fewer greenhouse gases when burned. It can be used in a variety of applications, such as shipping, heavy-duty transport, and power generation.

Bio-CNG (Compressed Natural Gas) is a biogas produced from organic wastes such as agricultural wastes, plant materials, animal by-products and other biological wastes. It is produced by fermenting biomass in biogas plants. The raw biogas is then upgraded to remove impurities such as carbon dioxide, hydrogen, and hydrogen sulfide. The upgraded biogas is then compressed to produce bio-CNG.

Bio-CNG is an environmentally friendly alternative to conventional fossil natural gas. It can be used as a fuel for vehicles or in industrial and domestic applications to generate heat and electricity. Because it is derived from renewable resources, it helps reduce greenhouse gas emissions and can help reduce dependence on fossil fuels.

1. Environmentally friendly: Biomethane is a renewable energy source that emits fewer greenhouse gases (such as CO2) when burned than fossil fuels. This helps reduce the environmental footprint.
2. Reducing dependence on fossil fuels: Biomethane can be used as an alternative to fossil fuels such as gasoline or diesel, reducing dependence on these resources. This is particularly important as fossil fuels are limited and their use has a significant environmental impact.
3. Energy independence: Since biomethane can be produced locally from regional biomass, it can help to increase the energy independence of countries. This can immensely reduce dependence on energy imports in the future.
