- BIOCH4NGE®
Upgrade biogas for RNG production with flexibility, scalability and efficiency.
BIOCH4NGE® upgrades biogas to pipeline-quality RNG with a membrane-based system that maximizes methane recovery while reducing energy consumption and operating costs.
The process begins with biogas purification to remove water and pollutants using a bed of activated charcoal. The purified biogas then passes through a high-efficiency membrane upgrading system that separates methane from carbon dioxide, producing RNG with specifications for injection, transportation fuel or industrial use.
With a modular and scalable design, BIOCH4NGE® delivers reliable, continuous operation across commercial and industrial biogas and RNG applications.
