**6. Conclusion**

Different technologies such as pyrolysis, liquefaction, gasification, torrefaction are reported to convert oilseed residues as high-valued products. Withal, in terms of "waste-to-energy" technology, pyrolysis is considered one of the most cost-effective and environmentally benign techniques. In order to reduce GHG emissions, pollution, global warming, and fossil fuel dependence, bio-fuel products can be used as drop-in alternatives to fossil fuels or blended with fossil fuels. An idea on importance of biopolymer compositions in preparation of pyrolytic products is reported. The different process parameters and their role in production process are reported. However, this article highlighted the selection of pyrolysis method and bio-polymer compositions in preparation of pyrolytic products. It critically explained the difference between process parameters depending on final product requirement. Yet, the research needs to establish toward the adaption of new methods of pyrolysis such as plasma, ultrasonic, microwave-assisted pyrolysis etc.
