Is Biodiesel fuel is better than the fossil fuels, or are there any factors we will need to compare them, and are we capable of replacing all the fossil fuel demands, these are all great questions. It's not that it's just a good alternative to our reliance on imported oil but it is also been shown to have a positive impact on our own health and the environment as a whole.
The nice thing about a biodiesel processor is that it is relatively small, meaning you can set one up in a shed or under an awning in your backyard. All this oil, fat, and grease will need to be processed in a specialized processor which removes any contaminates before it refines the oil into biodiesel fuel. There is also ongoing research into using sewage grow algae which is then used in the refining process.
And the best part is it can be oil that has already been used and recycled. Despite its wondrous properties, there are still few companies that directly sell biodiesel. It can be produced in any climate using the local resources.
Biodiesel is the future. There are subsequent environmental benefits when choosing to use biodiesel over conventional petroleum based diesel.
