The Standard - December 2022

Effective September 23, 2022, the United States Environmental Protection Agency (US EPA) announced its withdrawal of the interim registration review decision for the herbicide glyphosate. This update allows products containing glyphosate to remain on the market as well as continued use according to the product labels and application instructions.¹ The US EPA is currently conducting a registration review of glyphosate, which is required every 15 years, and expects to complete the review by 2026.

Did you know CIL separates and produces its own labeled compounds with carbon-13 (¹³C), oxygen-18 (¹⁸O), and deuterium (D) isotopes? In 1990, CIL constructed the world’s largest ¹³C isotope-separation plant, CIL Isotope Separations, LLC (CIS) in Xenia, OH, USA. In 2000, CIL responded to the worldwide shortage of ¹⁸O water by constructing, at that time, the world’s largest ¹⁸O isotope-separation facility at CIS, which remains one of the largest ¹⁸O isotope-separation facilities to date. CIS also houses the only large-capacity nongovernmental D₂O (deuterium oxide) enrichment columns. Since the initial construction, CIS has grown to 48 acres and there have been four past expansions of ¹³C production. With ever-growing needs for isotopically labeled compounds, CIL recently invested in a massive new expansion at CIS which is expected to be completed in 2024 and will significantly increase 13C production by building a separate cryogenic distillation facility for carbon monoxide.
