The cooking oil in your kitchen could be transformed to biodiesel. Oily biomass such as soybean, animal fats, or recycled grease make excellent feedstocks to produce the alternative transport fuel. Materials are combined with an alcohol in a transesterification reactor that converts the mass into crude biodiesel. The finished product is a low-sulfur, biodegradable fuel that can be used in its pure formulation or in petroleum diesel blends.

Convert raw biodiesel into the finished product
The transformation of organic waste into biofuel starts in the sanitization machine that deacidifies your base feedstock and degums it from wax content. This is when your biomaterial is ready to be pumped to the transesterification reactor and transformed into unrefined biodiesel.
This chemical process forms glycerin that you then need to separate from the fuel using a centrifuge. The remaining liquid passes through a filtration system, leaving you with upgraded biodiesel at the other end.
Diesel blends raise the emissions bar
Biodiesel offers a range of advantages over standard diesel. Besides being a renewable fuel, it emits lower levels of toxics and contaminants. And, unlike diesel, it does not spout any sulfur dioxide.
Although pure biodiesel can be used with existing technologies, it is more widely used in concentrations with regular diesel. Most products on the market contain either a maximum of 5% biodiesel (B5) or up to 20% (B20).
Biodiesel gets the green light
Large vehicles like trucks, buses, and trains usually rely on diesel engines, making biodiesel a central plank of strategies to reduce greenhouse gas emissions in the transportation sector.
Oil-bearing biomass is being used in the same way to develop alternatives to fossil jet kerosene. Sustainable Aviation Fuel (SAF) is projected to increase from 5% of the global jet fuel mix in the early 2020s to almost 20% by 2040.
