Synthetic fuel stocks are publicly traded companies creating transportation fuel from non-liquid feedstocks such as natural gas, coal, and municipal waste. Drop-in biofuel stocks are publicly traded companies creating transportation fuel from organic feedstock that can be used, transported, and stored by conventional petrofuel infrastructure. A synthetic fuel is a biofuel if it is made from organic feedstock. It is a drop-in fuel if it is compatible with the existing infrastructure for petroleum based fuels.
