Consider the following statements regarding First generation biofuels ...
To determine which statements are correct regarding first, second, and third generation biofuels, let's evaluate each statement individually:
Statement 1: First generation biofuels are made from sugar, starch, vegetable oil, or animal fats.
This statement is correct. First generation biofuels are typically derived from food crops or agricultural products such as sugar cane, corn, soybeans, and vegetable oils. These feedstocks contain high levels of sugar, starch, or oil, which can be converted into biofuels through processes like fermentation or transesterification.
Statement 2: Second generation biofuels are produced from micro-organisms like algae.
This statement is incorrect. Second generation biofuels are actually produced from non-food feedstocks such as agricultural waste, forest residues, or dedicated energy crops. While micro-organisms like algae can be used to produce biofuels, they fall under the category of third generation biofuels, not second generation.
Statement 3: Third generation biofuels are produced from non-food crops, such as cellulosic biofuels and waste biomass.
This statement is correct. Third generation biofuels are produced from non-food crops or feedstocks that do not compete with food production. Examples include cellulosic biofuels, which are derived from plant materials like agricultural residues, grasses, or wood chips, and waste biomass from various sources. These feedstocks have lower impact on food availability and can be more sustainable compared to first generation biofuels.
In conclusion, the correct statement is:
a) 1 only - First generation biofuels are made from sugar, starch, vegetable oil, or animal fats.

Consider the following statements regarding First generation biofuels ...
Biofuels are liquid or gaseous fuels primarily produced from biomass, and can be used to replace or can be used in addition to diesel, petrol or other fossil fuels for transport, stationary, portable and other applications. Crops used to make biofuels are generally either high in sugar (such as sugarcane, sugarbeet, and sweet sorghum), starch (such as maize and tapioca) or oils (such as soybean, rapeseed, coconut, sunflower).
Biofuels are generally classified into three categories. They are
- First generation biofuels – First-generation biofuels are made from sugar, starch, vegetable oil, or animal fats using conventional technology. Common first-generation biofuels include Bioalcohols, Biodiesel, Vegetable oil, Bioethers, Biogas.
- Second generation biofuels – These are produced from non-food crops, such as cellulosic biofuels and waste biomass (stalks of wheat and corn, and wood). Examples include advanced biofuels like biohydrogen, biomethanol.
- Third generation biofuels – These are produced from micro-organisms like algae.
