Not only are the biodiesel cars good for environment, but also they are also beneficial for the growth of the rural economy. In order to produce biodiesel, a large amount of oilseeds such as soybean needs to be cultivated. In addition, it is ideal to set up biodiesel plants in the countryside to reduce the production costs. These two factors should boost the rural economy a lot. In fact, this has already started to happen at a smaller scale as a lot of farmers now produce their own biodiesel domestically and use it to run tractors, cars and even small pumps.

However, one problem with using biodiesel in the city is that it is not available at every fuelling station. Usually gas stations in the rural areas have more chances to stock biodiesel as it is produced mostly in the countryside. But it is quite rare to find biodiesel in the city gas stations in the US. Do not despair; like many people are now doing in rural areas, you can also make your own biodiesel at home. In this way, you can save thousands of dollars each year while feeling proud of doing a community service by not contributing to the greenhouse effect.

The construction cost of a modular biodiesel processor will be anything between $200 and $3000 based on the capacity of the processor. These processors should be capable of producing from 20 to 50 gallons of 100% pure biodiesel. The production cost of the biodiesel should be below $1. However, you need to have some basic electrical and mechanical skills in order to set up your biodiesel plant. Foreknowledge of welding or doing any kind of metal work will certainly help. Also, you will need a lot of animal tallow or any kind of vegetable oil in order to start producing biodiesel.

You can construct a processor yourself after researching on the Internet. Setting up a processor yourself can be a bit messy, but not at all impossible. If you have a good budget, you can directly buy a modular processor and start producing your own biodiesel. Modular biodiesel processors are not usually sold in the conventional hardware shops in the US. However, a lot of independent biodiesel enthusiasts are setting up these processors and are ready to sell them at a good price. With some luck, you can find a very good modular processor at around $500, which can produce around 25 gallon biodiesel per batch.
