Biofuel
- It is a fuel produced from biomass.
- It can be produced from plants or from agricultural, domestic, or industrial biowaste.

First-generation biofuels
- It includes Bioalcohols, Biodiesel, Vegetable oil, Bioethers, and Biogas.
- These are made from food sources such as sugar, starch, vegetable oil, or animal fats using conventional technology.
- First-generation (1G) plants produce bioethanol from molasses by fermentation and biodiesel from non-edible oilseeds by esterification.
Second generation biofuels
- These are produced from non-food crops (portions of food crops that are not edible) e.g., stems, husks, wood chips, and fruit skins and peeling.
- Second-generation (2G) plants utilise surplus biomass and agricultural waste to produce biofuel.
Third generation biofuels
- These are produced from micro-organisms like algae.
