Been researching and debating making BD for a while and have seen people mention prices ranging from 50 cents a gallon all the way up to $2.50 a gallon. All of you making BD, taking into account the cost of electricity for heating and pumping, chemicals, and replacing filtering media, not factoring in the cost of making your processor, what is your closest estimate of cost per gallon to produce? I realize that a lot depends on where you live and the price of materials varies accordingly, but am just trying to get a realistic price range from a varied cross section of people across the country. Thanks in advance for your help.
