New Report Offers Roadmap to Advance Biological Manufacturing of Chemicals

 

WASHINGTON – A new report from the National Research Council lays out a 10-year roadmap to accelerate the use of biological synthesis and engineering in chemical manufacturing.  Advances in synthetic biology -- the ability to read, write, and edit the DNA of microorganisms -- have enabled the design and construction of new and more efficient chemical reaction routes within cells, which opens the door for making chemicals that cannot presently be made at commercial scale through traditional chemical manufacturing processes.  Biomanufacturing of chemicals could also help address global challenges related to energy, climate change, agriculture, and environmental sustainability by reducing toxic byproducts, greenhouse gas emissions, and fossil fuel consumption in chemical production, the report says.

 

In 2012, bio-based product markets represented more than 2.2 percent of the U.S. gross domestic product, or $353 billion in economic activity, and the markets for bio-based chemicals and industrial biotechnology for chemical manufacturing processes are growing roughly twice as fast as those in biomedicine or agriculture.  Despite the industry’s recent and projected growth, a number of technical and societal challenges must be overcome for biomanufacturing to be competitive with current chemical processes, the report says.  The roadmap identifies the necessary advancements in basic science and engineering that would expand the role of biotechnology in chemical manufacturing.

 

“We envision a future where biological and chemical approaches are viewed as equally viable options for chemical manufacturing,” said Thomas M. Connelly Jr., former executive vice president and chief innovation officer at DuPont and chair of the committee that wrote the report.  “Making progress in the areas identified in the roadmap will expand both the scale and scope of biomanufacturing of chemicals and play a major role in increasing the contribution of biotechnology to the national economy.” 

 

Product and capital costs are critical considerations for biomanufacturing.  Carbon in the form of fermentable sugars, derived from grains such as corn, is the primary raw material for the biological production of chemicals and often the largest single input cost -- up to as much as 65 percent -- of the total production cost, while fermentation itself represents the largest capital expense in bioprocessing.  One of the roadmap’s goals is increasing the widespread use of more abundant, more diverse, and less costly sources of carbon, such as from cellulosic biomass, natural gas, or biological methane.  Developments such as continuous fermentation to replace small-volume batch production will help to mitigate some capital costs at manufacturing facilities. 

 

The roadmap also calls for further research and development to facilitate chemical transformation via biological synthesis and engineering.  Improvements in the ability to rapidly design enzymes and engineer their properties to carry out specific complex chemical transformations would significantly reduce the costs of scaling up biomanufacturing processes.  In addition, the number and range of microorganisms engineered for industrial use will need to increase with the diversity of products manufactured.

 

Manufacturing chemicals through biology might produce societal benefits while requiring fewer trade-offs between growth and sustainability than traditional chemical manufacturing, the committee said.  Products based on biological sources such as plants, algae, bacteria, yeast, fungi, or other organisms could replace many chemicals now derived from petroleum or other fossil fuels, which are a limited resource.  The specificity of biological synthesis could lead to high-purity products with fewer toxic byproducts and less waste.  The report stresses the need for efforts to inform the public of the nature of industrial biotechnology and of its societal benefits, and to make sure that concerns are communicated effectively between the public and other stakeholders.

 

In addition to scientific advances, a number of governance and societal factors will influence the industrialization of biology.  Industry norms and standards need to be established in areas such as read/write accuracy for DNA, data and machine technology specifications, and organism performance in terms of production rates and yields.  An updated regulatory regime is also needed to accelerate the safe commercialization of new host organisms, metabolic pathways, and chemical products, and regulations should be coordinated across nations to enable rapid, safe, and global access to new technologies and products.

 

The committee recommends that relevant federal agencies support the scientific research and foundational technologies required to advance the areas identified in the report.  To ensure that the roadmap goals are pursued and to adapt as needed, government agencies should consider establishing a mechanism to provide ongoing direction for technology development, translation, and commercialization at scale.

 

The study was sponsored by the U.S. Department of Energy and National Science Foundation.  The National Academy of Sciences, National Academy of Engineering, Institute of Medicine, and National Research Council make up the National Academies.  They are private, independent nonprofit institutions that provide science, technology, and health policy advice under a congressional charter granted to NAS in 1863.  The National Research Council is the principal operating arm of the National Academy of Sciences and the National Academy of Engineering.  For more information, visit http://national-academies.org.  A committee roster follows.
