Chemical engineering startup?

buisness that can be developed in chemical engineering industry

There is no such animal as Chem Engg Industry. All chemical, polymer, food processing, brewing/ fermenting, petrochemical, pharma and biotech industries use chem engg. Usually these are very large scale operations except for the new niche things like 3d tissue printing and drug delivery systems development.
Chem Engg is a truly multidisciplinary area. It straddles too many manufacturing processes.
You may have to be more specific if you want people to suggest activities.
One activity that can be started in a smaller scale may be oleo resins (Flavours and essences) of natural herbs and spices.
