Question

how should waste ghee is dispose off ?

Answer 1

Melt them to boiling point level, and when cooling fileter them and add sodium hydroxide in appropriate proportion The Glycerene content will separate. Wash the Glycerene of impurities and when fully refined it can serve as Lubricant or serve clinical purposes. The Bio oil separated can be used as fuel. [The idea works only for sufficiently large quantities. I have used the oil as Tractor fuel.
