Okay, let’s tackle this. So Vijayendra Kumar has a Master’s degree in Chemical Engineering from the University of Arizona, which is a reputable institution. He has 36 years of experience in the industry, mostly at DuPont, which is a well-established company. His skills include plastics recycling, chemical engineering, and polymer science, which are in demand. Considering his education and experience, I would estimate his hourly rate to be around $125. This is slightly lower than the average rate for chemical engineers in the US, but it's also lower than the rate for someone with his level of experience and education. Some chemical engineers with similar experience and education can charge $200-$250 per hour, but Vijayendra's background in plastics recycling and his experience in leading roles bring his rate down.
