Cellulosic Ethanol Plant Retooled for RNG
Verbio North America says it will more than double the capacity of its plant in central Iowa to produce renewable natural gas from corn stover, and it plans to begin production of corn ethanol in the final months of the year. The facility was the first of three plants in the nation to return to biofuel production after faltering as a producer of cellulosic ethanol, made from grasses, woody plants, and crop residue.
