What is Biodiesel?

Biodiesel is an alternative fuel that can be used in diesel engines with little to no modifications. It is made through a chemical process called transesterification, which separates glycerin from the fat or oil. The result is methyl esters (the chemical name for biodiesel) and glycerin, a valuable byproduct often used in soaps and other products. Biodiesel is biodegradable, non-toxic, and produces significantly fewer emissions compared to petroleum diesel, making it an excellent choice for reducing the carbon footprint of your operations.


Benefits of Using Biodiesel


Environmentally Friendly

Biodiesel reduces greenhouse gas emissions by up to 86% compared to traditional diesel. By using biodiesel, you are actively contributing to cleaner air and a healthier environment.


Renewable and Sustainable

Unlike fossil fuels, biodiesel is made from renewable resources that can be grown and harvested sustainably. This helps decrease reliance on non-renewable energy sources and supports the agricultural sector.


Compatible with Existing Equipment

Biodiesel can be used in any diesel engine without significant modifications, making it an easy transition for businesses and fleets looking to adopt more eco-friendly fuel options.


Improved Lubricity

Biodiesel has better lubricating properties than petroleum diesel, which can help reduce wear and tear on engines, potentially extending the life of your equipment and lowering maintenance costs.


Supports Local Economy

By choosing biodiesel, you are supporting local farmers and producers who supply the raw materials for biodiesel production, contributing to economic growth and job creation in the community.
