===Fuel===
[[Biofuel]] is another option for using poplar as bioenergy supply. In the United States, scientists studied converting [[short rotation coppice]] poplar into sugars for biofuel (e.g. ethanol) production.<ref>{{cite journal |title=Can we use short rotation coppice poplar for sugar based biorefinery feedstock?

Considering the relative cheap price, the process of making biofuel from SRC can be economically feasible, although the conversion yield from short rotation coppice (as juvenile crops) were lower than regular mature wood. Besides biochemical conversion, thermochemical conversion (e.g. fast pyrolysis) was also studied for making biofuel from short rotation coppice poplar and was found to have higher [[energy recovery]] than that from bioconversion.<ref>{{cite journal |title=Fast pyrolysis of short rotation coppice poplar: an investigation in thermochemical conversion of a realistic feedstock for the biorefinery |journal=Biotechnology for Biofuels |volume=10 |issue=1 |page=144 |year=2017 |doi=10.1021/acssuschemeng.7b01000 |author1=Dou, C |author2=Chandler, D. |author3=Resende, F. |author4=Renata, R.}}</ref>
