My name is Chad Crouch, and I originally started this project for my own personal calculator and batch logger. I thought others could benefit from this as well, so I created this website where you can sign up and use it for free.

This website is all about logging and keeping track of your biodiesel production. It includes a calculator to do all the biodiesel calculations. You just input some information about each batch and it does the rest. It will even calculate what it's costing you and show you your total savings.

For those of you who are wondering exactly how it determines the amount of catalyst to use, here is the equation that is used. . .

Some Features of Biodiesel Log

• Calculator that will calculate...
• The amount of methanol to use (1, 2, or 3 carboys)
• The amount of catalyst to go in each carboy
• The amount of water to use for a prewash
• Your total cost for the batch you are making and individual costs (methanol, catalyst, biodiesel cost per gallon/liter, etc.)
• How much it would have cost you to buy the equivalent in "regular" diesel
• Your total savings compared to "regular" diesel
• A summary page that shows information about all of your logged batches
• Total batches made
• Total yield
• Total savings
• Total amount of methanol and catalyst used
• Optionally list your batches to other users of Biodiesel Log
