Bio based materials is a very large category which could include everything from ethanol, purified vegetable based oils, used cooking oils, fat by-products to bio based pyoils using wood or lignin feedstocks. The basic answer is yes, there are some bio based materials that can be used to produce drop-in fuels and a major example is the use of ethanol as a blend material for fuels.
However, great care must be used as you proceed to ensure it meets the fuel requirements and has the chemical stability properties required. A key to evaluate is the level of processing the specific bio based material has already undergone and the final produced quality specifications for the product. Is it already processed in a manner to produce a fuel blending stock or was it processed with a target to be a refinery co-processing feedstock? Understanding the answer to this question is needed to plan how to best use the bio based material.
