We are proud to say that the newest business area of our company, Renewable Products, is based on the NEXBTL technology, a product of our own R&D efforts. The technology is covered by patents.
With the NEXBTL technology, we can make top-quality renewable diesel and other renewable products out of nearly any waste fat or vegetable oil. Largely due to our technology, we have become the leading producer of renewable diesel in the world, with an annual production volume of more than 2 million tons.
NEXBTL technology is based on the hydrogen treatment of vegetable oils and waste animal fat
The renewable diesel we refine is hydrotreated vegetable oil (HVO), while the conventional biodiesel (FAME) has been made using the esterification method. The quality of our Neste Renewable Diesel is superior compared to traditional biodiesels. Unlike conventional biodiesel, the quality of Neste Renewable Diesel remains excellent even when the raw materials change. As a byproduct, NEXBTL technology can be utilized to make, for instance, renewable gasoline, and biobropane.
Neste Renewable Diesel can be used as such to replace fossil diesel, since their chemical consistency is similar. It can also be mixed with fossil diesel without any restrictions, or used in even at 100% concentration.
Due to its chemical consistency, it can also replace fossil raw material in uses other than traffic fuel. Neste's renewable fuels have been used and tested in airplanes, as a blending component for aviation fuel, in turbines, generators, ships, yachts, and the working machines used at mines and construction sites. Additionally, Neste Renewable Diesel can be used in the chemical industry, for instance as raw material for renewable plastics or as a renewable solvent in paints.
