Cleaning Used Oil
All soaps are made from a mix of oils; the most common ones are olive oil, coconut, sunflower, and other kinds of butter.
At Boavistacircular, we make cleaning soaps using reused cooking oil. Which are a mix of only vegetable sources—no animal fats.

Therefore, we can't say that our soaps are vegan as the oil might have been in touch with animal products. Even thou it is derived from vegetables and nuts.

So it has to go through a cleaning process.
We find the following method very efficient in removing impurities and odor:
