Dow Partners On Renewable Route To Acrylic Acid
Midland-based Dow Chemical Co. (NYSE: DOW) and Boulder, Colo.-based OPX Biotechnologies Inc. said Monday that the two companies are collaborating to develop an industrial scale process for the production of bio-based acrylic acid from renewable feedstocks.
Dow and OPX have signed a joint development agreement to prove the technical and economic viability of an industrial-scale process to produce acrylic acid using a fermentable sugar -- such as corn or cane sugar -- as a feedstock, with equal performance qualities as petroleum-based acrylic acid, creating a direct replacement option for the market.
If collaborative research is successful, the companies will discuss commercialization opportunities that could bring bio-based acrylic acid to market in three to five years.
Dow, a leading global producer of acrylic acid and esters, will provide its expertise in industrial chemistry, process optimization and product development. OPX, a company that uses biotechnology to convert renewable raw materials into biochemicals and fuels, will contribute its expertise in strain development and bioprocessing utilizing its EDGE (Efficiency Directed Genome Engineering) technology. The EDGE technology platform enables OPX to engineer high-performing microbes and bioprocesses more effectively and efficiently compared to conventional genetic engineering methods.
The global petroleum-based acrylic acid market is $8 billion and growing 3 to 4 percent per year. Acrylic acid is a key chemical building block used in a wide range of consumer goods including paints, adhesives, diapers and detergents.
"Dow is interested in bio-based products that are economically competitive to petrochemical-based products with equal or advantaged performance qualities," said Pat Gottschalk, business director and vice president, Dow Performance Monomers. "Through the use of innovative technologies and sustainable raw materials, this project may enable Dow to diversify its product offerings for customers."
During an 18-month pilot-scale program, OPX demonstrated with unprecedented speed and capital efficiency that its EDGE technology enables the manufacture of acrylic acid using renewable feedstock. A life cycle analysis conducted by Symbiotic Engineering, a greenhouse gas and sustainability consultant, concluded that OPXBIO's production process can reduce greenhouse gas emissions by more than 70 percent when compared to traditional petroleum-based acrylic acid production.
"Together with Dow, we aim to deliver bio-based acrylic acid to the market that is cost-competitive and more sustainable," said Charles R. Eggert, president and chief executive officer of OPXBIO. "Building on our own successful pilot-scale development and leveraging Dow's chemical processing and purification expertise will enable us to accelerate demonstration-scale activities and validate the performance of a bio-based acrylic acid in multiple applications."
