Product Description

The BioCNG™ system uses a patent-pending biogas conditioning system to economically produce biogas-based fuel to power CNG vehicles. BioCNG™ easily adapts to smaller-scale biogas-to-CNG alternative vehicle fuel projects. The economics of past small scale systems had often proved unfavorable, primarily because of the large capital and operating expense associated with cleaning and conditioning the biogas. BioCNG™, with its simple modular design, has been able to address these issues and produce a low cost RNG vehicle fuel.

BioCNG has received the U.S. Environmental Protection Agency’s (EPA) prestigious Landfill Methane Outreach Program (LMOP) Project of the Year Award for innovative technology.
