The production of bio-oils is being researched in the following two different ways. First, there is the extraction of bio-oils from a variety of biomass materials, using a special production process. See the poster pdf document -- Bio-Oil Extraction from Biomass  – for details on the bio-oil extraction process.
The second method of yielding bio-oils involves the biological conversion of renewable feedstocks to produce bioplastics and bio-oil. For further details on this process see the BIoplastics (overview)  and Bioplastics and Bio-Oil  sections of our website.
The primary contact for these efforts is HNEI Associate Researcher, Jian Yu . For further information on the researchers and general subjects of bio-renewable resources and biotechnology, see the Bio-Renewable Resources  and Biotechnology  sections of our website.
