Feedstocks

Biodiesel production using transesterification requires fat or vegetable oil as a feedstock.

Legally obtain/purchase oil feedstock from appropriate suppliers.
Carefully research all possible feedstocks for your biodiesel production. Choose the feedstock that best suits your needs, but don't forget the environmental benefits proper feedstock selection can provide. Remember that used vegetable oils can be recycled and processed to make biodiesel, which will often prove to be the most economical to obtain as well as better for the environment. However, keep in mind that the feedstock selected can affect the final product.
Practice proper disposal of unusable oils/wastes, such as spoiled oil, as well as impurities filtered from used oil in the recycling process.
Utilize used vegetable or cooking oil. One advantage of biodiesel is that it can be produced from many different used vegetable oils that would normally be discarded as waste. Using such wastes to make a usable product will help prevent improper disposal and protect the environment.

Take used cooking or vegetable oil from businesses without permission. As an example, a restaurant may be storing used cooking oil in a container behind the building. With today's high demand for vegetable oil, this typically will not be discarded as waste, but sold as another revenue stream for the restaurant. If you'd like to utilize used oil from a business, please contact their management for permission.
