In which we discuss per- and poly-fluoroalkylsubstances (PFAS) with Carol Kwiatkowski of the Green Science Policy Institute (https://greensciencepolicy.org), their properties, function, consumer products, toxicity, persistence, chemical analysis, and regulation both in the US and EU. Some companies, like Keen, are eliminating PFAS from their products. We then discuss a few green substitutes, including Solberg Co.'s firefighting foam, a fatty acid coated cellulose, and iron skillets. Host–Felicia Etzkorn of Virginia Tech, co-host–Jamie Ferguson of Emory & Henry College, with music by Wendy Godley of The Kind.

In which we discuss the opportunities for substituting safer chemical alternatives for consumer products in current use with our guest, Joel Tickner of the University of Massachusetts, Lowell. We don’t need to wait for green chemistry to come up with great alternatives, many have already been designed. We need to collaborate with businesses to turn towards better alternatives, rather than imposing regulations away from the bad stuff, risking drop-in substitutions that are just as bad. Host–Felicia Etzkorn of Virginia Tech, co-host–Jamie Ferguson of Emory & Henry College, with music by Wendy Godley of The Kind.

In which we discuss the uses of lead in gasoline (and the temporally and geographically associated violence), avgas, pipes, and car paint primer, and the greener replacements for these products—ethanol as replacement for tetraethyl lead as an anti-knock additive in gasoline, potential plastic replacements for lead pipes, and yttrium as a replacement for lead car primer.Host–Felicia Etzkorn of Virginia Tech, co-host–Jamie Ferguson of Emory & Henry College, with music by Wendy Godley of The Kind.

In which we interview Anthony Flaccavento, organic farmer, author, activist, and local politician, about his sustainable practices to incorporate carbon, nitrogen, and other essential elements back into the depleted soil of his former tobacco farm in southwest Virginia. No-till agriculture not only sequesters carbon and nitrogen in the soil, it balances soil water content in both drought and flood times. Host–Felicia Etzkorn of Virginia Tech, co-host–Jamie Ferguson of Emory & Henry College, with music by Wendy Godley of The Kind.

In which we discuss the effect of synthetic nitrogen fertilizer on feeding the world, and the synthesis of ammonia from nitrogen in the air and hydrogen generated from methane, first by the Haber-Bosch process and then by electrochemical processes with our guest, Dr. Michael Stoukides from the Aristotle University of Thessaloniki, Greece. Electrodes, catalysts, yields, rates, and the potential for energy storage are discussed for the electrochemical synthesis of ammonia.
