Waste vegetable oil is nothing however the used vegetable oil or cooking oil found in almost every kitchen. Most of the people throw out this used vegetable oil as they think it is of no use. But have you learnt that this used vegetable oil can be used as a fuel? Yes, it is true. Waste vegetable oil, when recycled, can be used as fuel in engines. These oils work best in diesel engines, like diesel generators or cars. The reason for using this oil as fuel is that it has advantages over petroleum diesel.
Vegetable Oil Fuel Conversion
However, before using this oil in diesel engines, it has to go through a conversion process. This can be achieved in two ways.
1. The primary way is to filter the waste vegetable oil before using it as a fuel. The fuel conversion process requires a further fuel tank, a heat source for heating the oil, and a filter for filtering the oil. Waste vegetable oil needs to be filtered because it contains many food particles. It has a comparatively high viscosity compared to petrol diesel, and is just too thick to work within the engine, and hence needs to be heated before use.
2. The second way of conversion is to convert vegetable oil into biodiesel. This converted biodiesel can be used directly in diesel engines without further modifications. The conversion of waste vegetable oil into biodiesel is a quite simple process, which could be carried out in a biodiesel factory. This conversion may also be carried out at home, but requires proper care and caution. It is because some materials used for this conversion are poisonous, caustic, and inflammable.
Advantages of Using Waste Vegetable Oil as Fuel
The primary advantage is that it is easily available in the kitchen. Secondly, it produces fewer greenhouse emissions, like carbon dioxide and sulfur, and thus reduces pollution to some extent.
The conversion process may be very cheap and produces less dangerous emissions as compared to a diesel engine. And after the conversion, there is tremendous decrease in production of emissions.
The conversion process to biodiesel is a bit expensive, but has many other advantages. The use of biodiesel contributes to reduction of many air toxic pollutants like dust particles, carbon monoxide, and sulfur oxide. It doesn’t require any special storage and is safer to handle as in comparison with petroleum diesel.
There are various factors that contribute to the efficiency of the fuel. The sort and quality of the vegetable oil used, the systems used for filtering and heating, the maintenance of the systems used, and the proper use of the systems are some factors. Efficiency of the fuel also is determined by the people developing this system, and if they have complete knowledge of how the system works or not.
So, now it is as much as you whether to use waste vegetable oil as fuel or to throw out it. But I recommend using it as fuel on account of the assorted advantages that it has over petroleum diesel. Also, by utilizing it you could contribute a bit of in preventing global warming.
