The disadvantages of biodiesel include a decrease in horsepower and a large amount of land devoted to growing the crops to create the fuel. Another disadvantage includes the fact that the fuel gels in cold weather.
Titration of biodiesel involves using a chemical reaction to determine the amount of acid in the biodiesel sample, commonly using a titrant such as potassium hydroxide. The titration process involves adding the titrant to the biodiesel sample until the endpoint is reached, typically indicated by a color change. The amount of titrant used can then be used to calculate the acidity of the biodiesel sample.

Biodiesel offers several advantages, including being a renewable energy source that can reduce greenhouse gas emissions and reliance on fossil fuels. It can also be produced from various feedstocks, such as vegetable oils and animal fats, contributing to local economies. However, disadvantages include potential competition with food production for land and resources, as well as concerns over deforestation and habitat loss if not sourced sustainably. Additionally, biodiesel can sometimes lead to engine performance issues and requires modifications for certain diesel engines.
Because its disadvantages far outweigh its advantages. ULSD motors require expensive conversions to run on biodiesel (contrary to what seems to be popular belief, you don't just pump biodiesel into any ULSD motor without conversion), and it doesn't perform as well as ULSD #2 does.
Cost, it's less efficient than ULSD, conversion to biodiesel is expensive, it gels more easily than ULSD does.
Biodiesel is important as using it slows global warming. Biodiesel, made from vegetation and algae, is used for powering vehicles and machinery instead of using diesel, which is a fossil fuel causing global warming.
Tallow is rendered mutton, beef or other bovine fat. Biodiesel can be made from tallow using similar methods and processes to plant oils. The resulting biodiesel has a higher cetane number than plant oil biodiesel meaning a cleaner and more efficient fuel.
Biofuel is organic, cheap, good for the environmet, and made from plants grown here in the US. Biodiesel is recycled oil that can be used to run cars and plains but it is not organic and the reproduction is not good for the environment at all and can be a bit more expensive. All in all they both have their advantages and disadvantages.
