Waste human hair has found a new use that can potentially make barbers rich. A team of chemical engineers at Dharmsinh Desai Institute of Technology in Nadiad has found that human hair is an excellent medium for separating oil from water. Industries currently spend a lot of money on chemical methods for separating oil from factory effluents to meet pollution standards. "Since human hair is very cheap the method may find a good usage for it (oil water separation)," scientists z.v.p. murthy, Gautam Kaushik and Ritesh Suratwala reported in the Indian Journal of Chemical Technology.
