Biorenewable chemicals are chemicals created by biological organisms that provide feedstocks for the chemical industry.<ref name=":1">{{Cite journal|last1=Nikolau|first1=Basil J.|last2=Perera|first2=M.

The tremendous diversity of enzymes in biological organisms, and the potential for [[synthetic biology]] to alter these enzymes to create yet new chemical functionalities, can drive the chemical industry. A major platform for creation of new chemicals is the [[polyketide]] biosynthetic pathway, which generates chemicals containing repeated [[alkyl]] chain units with potential for a wide variety of [[functional group]]s at the different carbon atoms.<ref name=":1" /><ref>{{Cite journal|last1=Garg|first1=Shivani|last2=Rizhsky|first2=Ludmila|last3=Jin|first3=Huanan|last4=Yu|first4=Xiaochen|last5=Jing|first5=Fuyuan|last6=Yandeau-Nelson|first6=Marna D.|last7=Nikolau|first7=Basil J.|title=Microbial production of bi-functional molecules by diversification of the fatty acid pathway|journal=Metabolic Engineering|volume=35|pages=9–20|doi=10.1016/j.ymben.2016.01.003|pmid=26827988|year=2016|doi-access=free}}</ref><ref>{{Cite journal|last1=Leber|first1=Christopher|last2=Da Silva|first2=Nancy A.|date=2014-02-01|title=Engineering of Saccharomyces cerevisiae for the synthesis of short chain fatty acids|journal=Biotechnology and Bioengineering|language=en|volume=111|issue=2|pages=347–358|doi=10.1002/bit.25021|pmid=23928901|s2cid=8117248|issn=1097-0290}}</ref> [[Polyurethane]] research is ongoing that specifically uses renewable resources.<ref>{{Cite journal|last1=Malani|first1=Ritesh S.|last2=Malshe|first2=Vinod C.|last3=Thorat|first3=Bhaskar Narayan|date=2022-01-01|title=Polyols and polyurethanes from renewable sources: past, present and future—part 1: vegetable oils and lignocellulosic biomass|journal=[[Journal of Coatings Technology and Research]]|language=en|volume=19|issue=1|pages=201–222|doi=10.1007/s11998-021-00490-0|s2cid=235442129 |issn=1935-3804}}</ref>
