Neste Oil successfully tested using spent motor oil in this way at its Naantali refinery at the end of May and now aims to begin using this material on a continuous basis.

With the continuing depletion of natural resources and the world's increasing demand for energy, we need to find new raw materials and use our existing resources more efficiently and more wisely. Neste Oil is already the world’s largest producer of renewable fuels from waste and residues, and our R&D people are working to increase our use of recycled materials such as spent motor oil.

—Lars Peter Lindfors, Neste Oil’s Senior Vice President, Technology

Using spent motor oil to produce traffic fuel is a continuation of the use of tall oil pitch as a feedstock that began at the Naantali refinery last year. Both materials represent waste that is otherwise difficult to reuse. Neste Oil also uses waste animal and fish fat and various vegetable processing residues as inputs for producing renewable diesel.

During 2013, Neste Oil produced enough renewable diesel from waste and residues to power more than 1 million cars for a year.
