We all know it: the world urgently needs sustainable fuels to curb climate change. But the raw materials for these fuels are often a problem. Many of the available waste products such as used cooking oils, animal fats, or other residues are low-quality, heavily contaminated, and difficult to process. They are full of impurities that would cripple traditional production facilities. So how can we efficiently transform these contaminated raw materials into high-quality fuels lik

Introduction As the renewable fuels industry grows, the shift from traditional fossil-based feedstocks to fats, oils, and greases (FOG) brings new challenges - chief among them, managing contaminants. The choice of pretreatment technology is critical, as it directly impacts downstream processing, product quality, and operational efficiency.
