Biogas (Renewable Natural Gas)

Renewable natural gas (RNG), also known as biogas or biomethane, can be used as transportation fuel in vehicles running on compressed or liquified natural gas.

Verbio has developed the technology to produce RNG from pure cellulosic material, such as the agricultural feedstocks of corn stover or wheat straw.

The feedstock undergoes the process of anaerobic digestion in large tanks over the course of 20-60 days. During this process, raw biogas is produced, comprising of 55% methane and 45% carbon dioxide. The carbon dioxide and other impurities are removed through a biogas treatment process, leaving nearly pure RNG gas, which is the chemical equivalent to the fossil fuel natural gas. The RNG is then injection into the natural gas distribution grid on site.
