Scaling Up! H2o

Can a carbon-negative, bio-based molecule replace legacy phosphonates and help you use less azole—without sacrificing corrosion performance? In this episode, host Trace Blackmore, CWT, welcomes Matheus Paschoalino, PhD Senior Business Development Manager and Microbial Control SME of Solugen, to unpack polyhydroxycarboxylic acids (PHCs) and how they’re changing cooling-water programs from the field up. We cover HEDP replacement in light-duty systems, azole enhancement in copper-challenged waters, a second-generation cut for heavy-duty heat flux, and PHC behavior with oxidizers and non-oxidizer biocides.  From Bioforge to Basin: How PHCs Are Made and Why It Matters  Paschoalino explains Solugen’s chemo-enzymatic “Bioforge” approach that oxidizes sugars (corn-syrup feedstock) into PHCs with very high yield and no practical byproducts—a pathway validated as carbon-negative. He outlines how different “cuts” (monoacid-rich vs. diacid-rich) map to different use cases, and notes current manufacturing capacity and ad
