The 17th Presidential Green Chemistry Challenge Award was announced in Washington on June 18. A group of companies and individuals that applied green chemistry technology to chemical research, chemical preparation, and utilization were honored. Polymer-related recovery and degradation technologies became popular on the day, occupying two seats among the six winners. For 17 years, award-winning technology alone has reduced the use or production of hazardous chemicals by more than 825 million pounds, saved 21 billion gallons of water, and reduced carbon dioxide emissions by 7.8 billion pounds.
Dr. Robert M. Weymouth of Stanford University and Dr. James L. Hedrick of San Jose, California, won this year’s academic award for their contribution to the field of organic catalysis. The organic catalytic technology they developed can remove the harmful metals in the plastic production process and produce safer end products, which are beneficial to the recycling of plastic bottles and can greatly reduce plastic waste.
Dr. Geoffrey W. Coates of Cornell University also won an academic award for his contribution to biodegradable polymer synthesis. He developed a biodegradable polymer synthesis technology that uses carbon dioxide and carbon monoxide as raw materials to synthesize biodegradable plastic products. The technology can be widely used in the field of adhesives, foams, and plastics, and it is hoped that a bisphenol A replacement product will be developed for the inner wall of cans.
Elevance Renewable Sciences, Inc. of Woodridge, Ill., won the Small Business Award for developing a low-cost technology for the production of high-performance green specialty chemicals. Compared with petrochemical production technology, this technology can reduce energy consumption and significantly reduce greenhouse gas emissions, and can be widely used in the production of consumer goods and industrial products.
Cytec Industrial received the Green Reaction Condition Award for developing the MAX HT Bayer Process Scale Inhibitor product technology. This technology can significantly increase the energy efficiency of alumina production and can reduce millions of pounds of hazardous waste acid emissions and billions of pounds of carbon dioxide emissions each year.
The Design Greener Chemical Award was awarded to the Buckman Company in Memphis, Tennessee. The fiber-modified enzyme technology developed by Buckman in the paper industry can increase the strength and quality of paper without adding chemicals or increasing energy consumption. It can also increase the proportion of recycled paper in the paper industry.
The Green Synthetic Route Award was awarded to Cady Cos in Redwood City, California, and a Ph.D. student at the University of California. They developed a more efficient and safe green chemistry method for the production of simvastatin drugs for the treatment of cardiovascular diseases.
STAINLESS STEEL PRODUCTS
Stainless steel is a corrosion resistant steel alloy with a minimum of 10% chromium. There are different grades and surface finishes of stainless steel produced to accommodate the environment in which the material will be implemented. Unlike carbon steel, stainless steel does not rust when exposed to air and moisture due to the sufficient amount of chromium present. The chromium creates an invisible passive film of chromium oxide that will not let oxygen attack the surface and prevents rusting of the iron base.
Yuhong Group is a stainless steel manufactory of more than 20 grades of Stainless Steel.
