The application of biomass-based resources for
the production of chemicals could slow the depletion rate of
fossil reserves and enable the development of a sustainable
chemical industry. Three sustainability metrics, the sustain-
ability value of resource replacement (SVrep), the sustainability
value of the fate of waste (SVwaste), and the sustainability
indicator (SUSind), were defined for biomass-based carbon
chemicals by using the ethanol equivalent (EE) as a common
currency. These sustainability metrics were calculated for
ethylene, propylene, toluene, p-xylene, styrene, and ethylene
oxide in the U.S.A. for 2008 and 2014. Our calculations are
based on the initial chemical dehydration of corn-ethanol to
ethylene followed by its conversion by existing chemical
processes. These basic chemicals cannot be produced sustainably at this time primarily due to the limited availability of bioethanol. Consequently, bioethanol-based carbon products should only be labeled “sustainable” when the necessary biomass is available to produce the required bioethanol, independently of social and economic changes. The waste management of the processes shows much better sustainability values than the resource management, due to the successful greening of petrochemical processes.
