For those who do not know... Andy, my brother, sold his beloved Chevy truck and bought himself a fancy shmancy Ford F350 Diesel.
Andy has decided to start using used oil from local restaurants to make Bio-Diesel (or as we lovingly refer to it as "Bio-Andy" since our dear Willie Nelson's bio-Willie is no longer). This is his super duper bio-making machine :)
What's my part in all of this bio-diesel talk? One of the byproducts from making BioD is glycerin. Many people simply dump this stuff out. That is not an environmentally good way to deal with it. We are making soap out of the glycerin. If you look on your common cleaners and soaps you will notice that they use glycerin too.
The jar on the left is made with mixed oils (veggie, canola, soy). The the jar on the right is made with peanut oil. Both have the bio-diesel layer on the top and the glycerin layer is settled on the bottom.
Until we get our still made, I am cooking the glycerin layer in buckets in the sun for two days and then sticking it in a pot on the BBQ to boil it.
Once cooled, I mix water, a caustic, and a few drops of scent into the glycerin. A few minutes of stirring and I have soap!!! Since we are using oils that are liquid at room temperature, bar soap is VERY difficult to make. Our liquid soap is gentle and safe to use as shampoo and body soap, safe enough to use as a dish soap, tough enough to use as a degreaser and laundry soap.
This is Andy's site he is very slowly building. He started building it only a few days ago.
