Biodiesel Production Unit is an industrial setup designed to produce biodiesel, a renewable and biodegradable fuel, from various organic feedstocks. The primary raw materials include vegetable oils (like soybean or canola oil), animal fats, and recycled cooking oils. The production process involves a chemical reaction known as transesterification, where these oils or fats react with an alcohol (commonly methanol or ethanol) in the presence of a catalyst to form fatty acid esters (biodiesel) and glycerin as a byproduct. The resulting biodiesel can be used in its pure form (B100) or blended with petroleum diesel in various proportions (e.g., B20, which is 20% biodiesel and 80% petroleum diesel) . Biodiesel is compatible with most diesel engines without significant modifications and contributes to reduced greenhouse gas emissions, making it a cleaner burning alternative to fossil fuels .
