SAF companies working on Fat-to-Fuel

Sustainable aviation fuel made from waste oils and fats is known as first-generation SAF and is the most efficient way to produce SAF because fats have been used for biodiesel production for many years.

The most common feedstock is plant or animal fats and greases that have been used for cooking and are no longer suitable for further cooking, as well as waste from food production, such as tallow.

According to Neste, this HEFA SAF can only cover around 10% of global jet fuel use because there are not enough waste oils and fats available to produce the billions of gallons of SAF the world needs, and getting the feedstock is not cheap.

DID YOU KNOW?

Traditional oil companies can adapt their existing refineries to co-process 5% feedstocks – such as used cooking oil – alongside fossil fuels.

BP has already begun producing SAF using this method in Lingen, Germany, and plans to do the same at four other refineries. While co-processing is an important step, it still is not enough to meet the growing demand for SAF. Stand-alone units will also be required to ramp up production, according to Andreea Moyes, Air bp's global head of Sustainability. BP's goal is to eventually add up to 30% renewable feedstock.
