Its significance has surged in response to increasing fossil fuel depletion and environmental concerns, positioning biodiesel as a crucial component in the global shift towards sustainable energy sources. Notably, biodiesel can reduce greenhouse gas emissions and improve air quality, making it a pivotal player in addressing climate change and energy security.  Biodiesel is categorized into three generations based on its feedstock: first-generation biodiesel is derived from edible oils, second-generation from non-edible oils and waste materials, and third-generation from microbial lipids, particularly microalgae. While first-generation biodiesel […]
