Cleantech Chemistry thanks C&EN colleague Marc Reisch for contributing this news about biobased chemicals.
M&G Chemicals, a unit of Italy’s Gruppo Mossi & Ghisolfi, plans to build a $500 million biorefinery in China to make ethanol and the polyester raw material mono-ethylene glycol from 1 million metric tons of biomass per year. The facility in Fuyang, Anhui Province, China, will be four times larger than M&G’s recently commissioned Crescentino, Italy-based biorefinery when it is open in 2015.
To be built in a joint venture with minority partner Guozhen Group, a Chinese energy and real estate conglomerate, the Fuyang refinery will use Proesa technology from Beta Renewables, a joint venture partly owned by M&G which is also a polyethylene terephthalate maker.
M&G’s CEO Marco Ghisolfi says the Fuyang refinery “is the first act of a green revolution that M&G Chemicals is bringing to the polyester chain to provide environmental sustainability.” The company’s entry into China will ultimately position it to supply PET to firms such as beverage maker Coca-Cola which have advanced the development of renewably-sourced bottles, among them Coke’s own “PlantBottle.”
Coke currently buys ethanol-based ethylene glycol from India Glycols to make a PET bottle that is nearly 30% biomass derived. To increase feedstock availability, last year Coke formed a partnership with India’s JBF Industries to build a 500,000 metric-ton-per-year bio-ethylene glycol plant in Brazil, also set to open in 2015.
While the JBF plant will use sugarcane and sugarcane-processing waste as feedstock, M&G’s China facility will be based on wheat straw and corn stover. So M&G’s plant has the added virtue of depending on a non-food feedstock source.
But the ethics of using one feedstock crop versus another, or of using biomass versus petrochemical feedstocks, might not matter if consumers don’t care. At the BioPlastek Forum, a conference held in June, Coke, Ford Motor, and yogurt makers Danone and Stonyfield Farm told bioplastic makers that most consumers are unwilling to pay higher costs for bioplastics (C&EN, July 15, page 18).
And while the large M&G and JBF plant may have the economies of scale to drive down bio-based PET costs, they’ll encounter headwinds from petrochemical-based ethylene glycol makers. Lux Research senior analyst Andrew Soare points to the spate of ethylene and derivatives plants planned in the U.S. based on low-cost natural gas. M&G itself, for instance, is building a 1 million metric-ton-per-year PET polymer plant in Corpus Christi, Texas.
However, M&G will be challenged to make cost competitive ethylene glycol in China given the competition expected from U.S. petrochemical producers, Soare says.
