Greener Peppers: A Sustainable Food Analysis Method

February 3, 2023

The analysis of peppers for flavor profiles and food volatiles is not new. With a wide array of varieties, peppers find uses in not just food markets, but also pharmaceutical and cosmetic industries. Analyzing peppers isn't new. Finding ways to increase the sustainability and "green" qualities of those analyses, however, is an ongoing challenge, and one that Micaela Galletta, Mariosimone Zoccali, Donato Creti, Luigi Mondello, and Peter Q. Tranchida tackled in a recent study published in Green Analytical Chemistry.

Biomass to Markets: Determining Value

January 20, 2023

As global industrialization has increased, so too has global waste. Over 2.6 trillion pounds of waste are generated worldwide each year. Energy demands continue to grow year over year, and the Earth's population is looking toward greener solutions. Those 2.6 trillion pounds of trash may be waste now, but some of it may be suitable as biomass.

Automating Better Water: The TGA and Water Treatment

May 13, 2022

Clean, safe water is a cornerstone of life itself, and the ability to properly process and treat wastewater is a key component in environmental preservation. As such, water treatment plants such as Veritas S. p. A (Veneziana Energia Risorse Idriche Territorio Ambiente e Servizi) are a critical part of water infrastructure, and the analytical methods they use are a critical part of water treatment.

Discovering DDT: How GCxGC is uncovering an environmental disaster

April 23, 2021

Sunset over the Pacific Ocean, in Seal Beach, California.For years, environmentalists have known about the contamination of DDT in the ocean waters off the California coast. Montrose Chemical Corporation, the largest producer of DDT in the United States from 1947 until 1982, was infamously dumping chemical waste from their manufacturing process into the sewer system, contaminating the Palos Verde Shelf and eventually requiring the area to be designated as a Superfund site in an attempt to clean up the environmental damage. However, the known DDT contamination did not seem to be enough to explain the abnormally high cancer rates in the local sea lions.

Chasing a hunch, David Valentine, a professor of geochemistry and microbiology at UC Santa Barbara, dove deeper.
