awarding 'green chemistry'
O
ne important challenge that continues to receive the attention
of scientists and engineers worldwide is the creation
of a more sustainable environment. The U.S. Environmental
Protection Agency (EPA; www.epa.gov) recognizes
achievements in this area through the Green Chemistry Challenge
Awards, which " promote the environmental and economic benefits of
developing and using novel green chemistry. "
Last month, the 2020 recipients of these awards were announced.
Details about the award and selection criteria can be found on the
EPA's website. The five winners of the 2020 Green Chemistry Challenge
Awards are described here (Source: EPA).
Greener Reaction Conditions Award - Merck & Co. (Rahway,
N.J.; www.merck.com) was recognized for improving the process
used to produce certain antiviral drugs. The existing synthesis processes
were inefficient due to poor chemoselectivity and the need
for multiple reaction steps that involved expensive and hazardous reagents.
Merck developed a catalyst that reduced the process to two
reaction steps with a high purity yield. The new process is said to improve
manufacturing efficiency and sustainability of one antiviral drug
by more than 85%, with improvements in energy use, water depletion
and other metrics.
Greener Synthetic Pathways Award - Genomatica (San Diego,
Calif.; www.genomatica.com) received this award for developing
a new brand of 1,3-butylene glycol - which is used in cosmetics
- via a one-step fermentation process that uses renewable sugar
feedstock and engineered E. coli. Genomatica's process replaces the
traditional fossil-fuel-based production route that uses acetaldehyde
and heavy metals, thereby reducing greenhouse-gas emissions and
eliminating the use of more hazardous materials. The company has
already produced the butylene glycol at commercial scale.
Designing Greener Chemicals Award - Johns Manville, a Berkshire
Hathaway Company (Littleton, Colo.; www.jm.com) was recognized
for developing a thermoset binder for fiberglass reinforcement
that is approximately 90% biobased, and free from formaldehyde. The
process uses renewable carbohydrates produced from corn, potato
or wheat starch. In addition to eliminating formaldehyde, the new
technology uses water and energy more efficiently and produces a
product with performance advantages.
Academic Award - Recognition was given to professor Steven
Skerlos, from the University of Michigan and Fusion Coolant Systems
(Canton, Mich.; www.fusioncoolant.com) for developing a
technology that uses supercritical CO2 for metalworking in place of
traditional oil-based metalworking fluids. The traditional fluids can
be difficult to treat after use, because they may contain hazardous
additives, or heavy metals that may be picked up during the metalworking
itself. The new technology developed at the University of
Michigan, and being commercialized by Fusion
Coolant Systems, uses little to no oil lubricant.
Small Business Award- Vestaron Corp. (Kalamazoo,
Mich.; www.vestaron.com) received this
award for the development of a new biopesticide
that controls targeted pests with no adverse effects
on the environment, people and wildlife. The novel
insecticide is based on a peptide that is found in a
spider's venom. The peptide is produced by yeast
fermentation using sugar derived from corn.
