From recuperative furnace to 100% oxy-fuel furnace
We transformed an old recuperative glass furnace based on air-fuel combustion to 100% oxy-fuel for a glass company.

Understanding Biomethane and its Benefits
Biomethane is a combustible gas produced from biogas, through a process called “biogas upgrading”. This process removes impurities from the biogas, allowing it to be reused as a form of renewable energy – also providing economic advantages, such as lowering energy costs and improving financial performance.
Our Innovative Biomethane Solutions
From waste to energy, we are present at every step of the biomethane value chain.
Using a circular economy model, we can process your waste products (such as food, agriculture, and sewage sludge) into biogas, which is then upgraded and other gases like CO2 are extracted, resulting in the production of biomethane – a renewable fuel.
The obtained biomethane can be adapted according to the specific needs of its utilisation, using various biomethane valuation techniques such as liquefaction.
We can also use our CO₂ recovery technology to reuse the discarded CO₂ from the upgrading process, to be upcycled or sold for other applications.
Renewable energy generation. It´s a clean and 100% renewable gas
Decarbonisation, reducing greenhouse gas emissions
Economic assessment of waste. It is produced from biogas, transforming waste into resources
Vacuum Pressure Swing Adsorption
Vacuum Pressure Swing Adsorption
Using differential adsorption, this separation method efficiently separates methane (CH4) and carbon dioxide (CO₂) on an adsorbent material, offering low energy consumption. It also partially separates nitrogen (N₂) and minimises methane losses while handling biogas with high O₂ and N₂ concentrations.
