First-generation biofuels (also denoted as "conventional biofuels") are made from food crops grown on arable land. [ 20 ] [ 21 ] : 447 The crop's sugar, starch, or oil content is converted into biodiesel or ethanol , using transesterification , or yeast fermentation.
Biodiesel is a liquid fuel composed of vegetable oils and or animal fats. To create the gasoline itself, these subsequent liquids are combined with alcohol. Biodiesel is used to fuel compression ignition engines, otherwise known as diesel engines. The most common product of biodiesel is B20, a 20:80 blend: 20% biodiesel to 80% petroleum diesel.
A biofuel made from waste or inedible vegetation, with renewable energy to power the production, would have little or no greenhouse gas emissions, making it a clean fuel.
Biomass in this context means plant materials and animal waste used especially as a source of fuel. First-generation biofuels are made from sugar-starch feedstocks (e.g., sugarcane and corn) and edible oil feedstocks (e.g., rapeseed and soybean oil), which are generally converted into bioethanol and biodiesel, respectively.

Pure biodiesel (B-100) made from soybeans. Biodiesel is commonly produced by the transesterification of the vegetable oil or animal fat feedstock, and other non-edible raw materials such as frying oil, etc.
Alternative fuels, also known as non-conventional and advanced fuels, [1] are fuels derived from sources other than petroleum. [2] Alternative fuels include gaseous fossil fuels like propane, natural gas, methane, and ammonia; biofuels like biodiesel, bioalcohol, and refuse-derived fuel; and other renewable fuels like hydrogen and electricity.

Biodiesel is produced from oils or fats using transesterification and is the most common biofuel in Europe. In 2010 worldwide biofuel production reached 105 billion liters (28 billion gallons US), up 17% from 2009, and biofuels provided 2.7% of the world's fuels for road transport, a contribution largely made up of ethanol and biodiesel.

Biodiesel production is the process of producing the biofuel, biodiesel, through the chemical reactions of transesterification and esterification. [1] This process renders a product (chemistry) and by-products. The fats and oils react with short-chain alcohols (typically methanol or ethanol). The alcohols used should be of low molecular weight.
