Bio-LNG, which is Liquefied Natural Gas produced from renewable biological sources, offers several significant advantages. Some of them are detailed below:
- Low carbon footprint: Bio-LNG is produced from renewable sources, such as agricultural, livestock and agri-food waste, which means that its production emits less greenhouse gases compared to conventional fossil fuels. By using organic waste instead of fossil fuels, it reduces carbon dioxide (CO2) emissions and contributes to climate change mitigation.
- Versatile use: Bio-LNG can be used in a wide range of applications, including heavy transportation, power generation, heating and industrial processes. Its versatility makes it a viable and sustainable alternative to replace fossil fuels in different sectors.
- Efficient storage and transportation: LNG has the advantage of being a highly energetic and compact fuel in its liquid form, which facilitates its storage and transportation over long distances. This allows its distribution and supply to areas where access to other energy sources may be limited.
- Waste reduction: Bio-GNL production utilizes organic waste that might otherwise end up in landfills or be disposed of inappropriately. By harnessing this waste and converting it into a usable energy source, it reduces the amount of waste and promotes more efficient and sustainable resource management.
- Promoting the circular economy: Bio-LNG is part of a circular economy approach, as it uses waste and by-products from other industries to produce energy. This not only reduces dependence on fossil resources, but also boosts job creation in the biofuels value chain and promotes sustainability in the energy sector.
In summary, Bio-LNG offers benefits such as a low carbon footprint, versatility in its use, efficiency in storage and transportation, waste reduction and promotion of the circular economy. These advantages make it an attractive option for the transition to a more sustainable and environmentally friendly energy matrix.
The production of Liquefied Natural Gas (LNG) from livestock, vegetable and agri-food waste using the Cryo Pur liquefaction system follows a specific process. Here I explain how it is carried out:
- Waste collection: Livestock, vegetable and agri-food waste is collected from different sources, such as farms, food processing plants and agricultural crops.
- Pretreatment: The waste undergoes pretreatment to remove impurities and unwanted components. This may include solids separation, filtration and contaminant removal.
- Liquefaction: After pretreatment, the waste undergoes a liquefaction process using the cryo pur system. This system uses cryogenic technology to cool the waste to extremely low temperatures, converting it into a liquid phase.
Separation and purification: Once liquefied, the waste components are separated through a purification process. This involves removing any unwanted or contaminating residues, such as solid particles, undesirable gases and harmful compounds.
- Obtaining LNG: The product resulting from liquefaction and purification is treated as conventional natural gas. It is cooled to an even lower temperature to convert it into LNG, which means reducing its volume and making it easier to transport and store.
It is important to note that the production of LNG from livestock, vegetable and agri-food waste using the cryo pur system may require specific adjustments and adaptations depending on the characteristics of the waste and the technical requirements of the process.

" “GNL VERDE” refers to liquefied natural gas produced from renewable or low-carbon sources, in contrast to conventional LNG produced from conventional natural gas sources.
Here are some benefits of using green LNG compared to conventional LNG:
- Reduction of greenhouse gas emissions.
- Improvement of air quality.
- Support for sustainable development.
- Compliance with environmental regulations and requirements.
The steel industry uses liquefied natural gas (LNG) in various aspects of its production. Here are some of the most common uses of LNG in the steel industry:
Direct reduction of iron ore: LNG is used in the direct iron ore reduction process. In this process, natural gas or synthesis gas, obtained from natural gas, is used as the reducing agent instead of the coke used in the traditional blast furnace. LNG supplies the gas needed to reduce iron ore to sponge iron or metallic iron in a direct reduction reactor.
Power and heat generation: Steel plants require large amounts of energy to operate their equipment and machinery. LNG is used in gas turbines to generate electricity and in boilers to produce steam and heat. This energy and heat are used in different stages of the steel production process, such as heating furnaces, supplying power to machines and equipment, and generating steam for various applications.
Oxygen blowing in converters: In some steelmaking processes, such as the basic converter or basic oxygen converter (BOF), LNG is used to supply additional oxygen to the process. LNG is converted to natural gas after vaporization and is used as a means of injecting oxygen into the converter, helping to oxidize impurities present in the molten iron and improve the quality of the steel.
Temperature control: LNG is also used in cooling and temperature control at different stages of the steel production process. It can be used to cool flue gases or as a cooling agent in cooling systems in the steel industry.
