As a visiting student, Kaitlyn Lawrence continued her work on the catalytic use of waste to energy ashes in NOx reduction at the Centre de Recherche d’Albi en génie des Procédés, des Solides Divisés, de l’Énergies et de l’Environnement (RAPSODEE). The French group, who’s name translates to the Albi Research Center for Process Engineering, Divided Solids, Energy, and the Environment, is led by Dr. Ange Nzihou, a pioneer in the area of waste valorization. He advised Lawrence during her brief, 3-week visit to Albi, in which she did characterization experiments of ashes using inductively coupled plasma atomic emission spectroscopy (ICP-AES) and X-ray fluorescence (XRF) spectrometry.
