As I approach the end of the first season of "The Laws of Stan," I took the liberty of recording an episode featuring not one, but two incredibly inspirational guests: Jason Plant and Nicole King, respectively CEO and Lead Engineer of Hydrophos Solution, a young company aiming to develop technologies for extracting phosphorus from wastewater and reselling it to the fertiliser industry. ?As I sought to broaden my interest in the extensive network of applied mathematics, I stumbled upon a venture launched by young Americans in the chemical industry. ?⚛️I hope you all enjoy this episode, which illustrates the applications of mathematics in the life sciences and chemical engineering industries. Please support these entrepreneurial individuals challenging the circular economy through a sustainable project. ?‍♂️
