Although beverage companies like Coca-Cola Ltd. have adopted biobased-PET since 2009, they use petroleum based TPA and therefore the PET’s percentage biomass carbon content is a mere 20%. In a February 2015 publication , researchers propose a viable synthetic route, shown in Figure 1 (below), for the preparation of biobased TPA from furfural alone, which is produced industrially from inedible cellulosic biomass.
Furfural is an ideal biomass resource, as it is traditionally produced from cellulosic and waste biomass such as corncob, corn stock, and rice hull. Furthermore, it is extremely abundant, with a global output of 500,000–1,000,000 tonnes/year.
PTA is expected to grow at a Compound Annual Growth Rate (CAGR) of 5.3% from 2011, reaching 66 million tons in 2020, with Asia-Pacific expected to account for around 82% of its demand.
