A variety of oils can be used to produce biodiesel which include:
Waste vegetable oil (WVO).
Algae, which can be grown using waste materials such as sewage and without displacing land currently used for food production.

Biodegradable and Renewable Fuel.
Safer to use and has low toxicity compared to fossil diesel fuel.
Lower exhaust emission rate than normal diesel fuel.
Biodiesel and biodiesel blends are used in almost all diesel engines and vehicles
It is a carbon-neutral liquid, which means that the combustion of biodiesel never produces the net output of carbon in the form of carbon dioxide like other mineral diesel.
Biodiesel has been approved for up to 20% mix with petrol-diesel as a world standard. However, any percentage mix up to 100% can be used, particularly with new, modified engines.
Biodiesel reduces particulate discharge from engines at any concentration. Particulates from petrol-diesel cause lung problems such as asthma.
Used as heating oil In many commercial & domestic boilers, biodiesel is also used as heating fuel.
Drilling fluid
Lubrication
Oil spill cleaning
Emulsifying agent

The production of biodiesel involves a chemical reaction. This chemical reaction is known as transesterification which converts natural fats and oils into Fatty Acid Methyl Esters (FAME) or Biodiesel.
Some of the major sources of suitable oil (to make biodiesel) come from crops like palm, soybean or rapeseed. High-quality biodiesel is made from rapeseed, but nowadays most of the biodiesel is produced from waste vegetable oils obtained from chip shops, restaurants, and industrial food producers.
“Biodiesel is a renewable, biodegradable fuel that is manufactured from vegetable oils, and animal fats.”
Biodiesel is an alternative clean-burning renewable fuel similar to conventional diesel. It is produced using animal fats, vegetable oils, and waste cooking oil. Due to its biodegradable nature, it is used as a replacement for fossil diesel fuel. It can also be mixed with petroleum diesel fuel in any proportion.
Blends of biodiesel and conventional hydrocarbon-based diesel are most commonly distributed for use in the retail diesel fuel marketplace. Much of the world uses a system known as the “B” factor to state the amount of biodiesel in any fuel mix:
• 100% biodiesel is referred to as B100
• 20% biodiesel, 80% petrodiesel is labeled B20



Conventional diesel can start to cloud or even gel in cold weather. Biodiesel fuels have similar cold weather limitations but have higher cloud and pour points.
However, these limitations are largely mitigated when using B20 biodiesel fuel.
During sustained below-freezing temperatures, cold weather performance can be managed via the use of cold flow additives or using a winter grade diesel in the biodiesel blend
