Making Biodiesel Fuel at
Imagine being able to make your
own fuel at home. It is a reality and anyone can do
it. It is easy to make you own fuel at home. All
you need are some simple supplies that you can get at your
hardware store. Within hours you can have a batch of
clean burning biodiesel that you can use to fuel your
What you will need to make biodiesel is 1 liter of vegetable
oil, antifreeze and lye. You will also need a blender,
scales, plastic containers, funnels, empty water bottles, duct
tape and a thermometer.
NOTE: Make sure that all of the equipment you plan to use is
cleaned and thoroughly dried. You will also want to make
sure that all equipment is kept separated so it is not used for
any other purpose except making biodiesel.
You will start the process by measuring 200 ml of antifreeze
and putting into one of the plastic containers using a
funnel. You will now want to mix in lye. The lye
will quickly absorb the antifreeze, so you need to work
fast. If you work too slowly the lye will absorb water
from the air and will ruin the process. To mix the
ingredients you should cover the container and shake it until
it starts to feel warm. It should foam up which indicates
it has produced sodium methoxide. Once the sodium
methoxide is produced and is clear it is time to move onto the
Now you will need the blender. You will need vegetable
oil that has been heated to 130 degrees Fahrenheit. Mix
the vegetable oil with the sodium methoxide. You will
want to pour it into the blender and cover it tightly.
Now blend the mixture for 20 minutes.
After 20 minutes you can then remove the mixture from the
blender. Use a funnel to pour it into the 2 liter
bottles. You will then need to allow it to sit for 8
hours. This allows it to settle and will separate out the
As it settles you will see a darker layer form on the bottom
which is the glycerin. The pale liquid layer at the top
is the biodiesel. After it has completed separation you
can then remove the biodiesel and put it in a glass jar or
Now you will want to prepare two wash bottles. You
will poke a small hole in the corner of two bottles and then
cover the holes with duct tape. Pour the biodiesel into
one bottle and add a half liter of water to it. Put the
cap on the bottle tightly. Turn the bottle on its side
and roll it until well mixed. Now you can drain the water
by removing the duct tape and pouring it out. Put the
duct tape back on once all the water is removed.
Once the biodiesel becomes clear it is ready for use.
You should be aware that it can take up to a week for the
process to be completely finished and the biodiesel to be
The process of making biodiesel is not hard and actually
can be quite fun. It is sort of like a high school
science project. However, making biodiesel can save you
thousands of dollars.
