Bio-Diesel production by products, what do you do with them? Answered
I have seen some folks hawking their books for DIY Home Made Bio-Diesel. Ok, it can be done but what do you do with the byproducts, i.e. the initial sluge produced when titrating the primary oil with lye, then washing the resulting oil with water to titrate out the soap? It seems to me a lot of work and mess to deal with.
