Professor Bungay will answer questions, but he is only expert in such areas as fermentation, biomass refining, and bioconversions. He gets many questions about other topics (often about incineration) because of his web pages, but these are presented for teaching. He has little to add to these other topics beyond what is found in textbooks.
