Polyethylene furanoate (PEF), obtained by polymerization of FDCA with EG, while not yet commercialized, is considered a potential alternative to PET for packaging applications. PEF has the advantage of being fully bio-based and better barrier properties than PET while having similar mechanical properties. The most studied production route to FDCA is the oxidation of 5-hydroxymethylfurfural (HMF), a versatile platform chemical for production of renewable materials. HMF is typically obtained via dehydration of furanoses, although efforts on one-pot preparation from waste biomass, combining cellulose depolymerization and monosaccharide dehydration, have been reported. Research on FDCA synthesis has been focused on the development of efficient, inexpensive, and greener catalysts for the oxidation of HMF. Thus, while noble metal catalysts such as platinum have proven more effective, enzymes and electrocatalysis have drawn considerable interest. Ethylene is the most produced industrial organic compound. Bio-based ethylene is primarily prepared from the commercially established bioethanol, which is obtained most often by fermentation of sugarcane or other biomass feedstocks. Ethanol is converted into ethylene via intramolecular dehydration at elevated temperatures in the presence of catalysts. Aluminum oxide, silica and zeolites are among the commonly studied catalysts. In most cases, high ethylene selectivity and quantitative ethanol conversion have only been achieved at temperatures above 400 o C or by using expensive lanthanum dopants; however, Sheng et al. reported bioethylene production at 98.8% selectivity and 99% ethanol conversion at 250 o C using HZSM-5 zeolite catalyst. The 2019 global bioethylene market was $414 million, compared to $166 billion for the total ethylene market.
