A primary objective of the Renewable Fuel Standard (RFS) implemented in 2007 was to stimulate the production of at least 16 billion gallons/year of gasoline and diesel made from cellulosic biomass, or non-food crops and waste biomass like corn stalks, corncobs, straw, wood, wood byproducts and animal manure. But the vision of making gasoline from wood chips never materialized and today’s cellulosic biofuel is a whole different ballgame. In today’s RBN blog, we look at the evolution of cellulosic biofuels and the D3 Renewable Identification Number, aka the D3 RIN.
