Methane, traditionally a potent greenhouse gas, can serve as a sustainable feedstock across various industries when captured and utilized effectively. As biogas, methane can be refined into biomethane or compressed biogas (CBG), offering a renewable energy alternative for industries like transportation, heating, and electricity generation. Furthermore, methane can be leveraged as a raw material in the production of bio-based chemicals and materials, such as bioplastics, through processes like precision fermentation. This approach reduces dependency on fossil fuels and can convert waste sources (e.g., agricultural residues, municipal waste) into valuable products, aligning with circular economy principles and contributing to reduced greenhouse gas emissions.
