Neste Oil aims to continuously improve its material efficiency. We seek new raw materials and actively develop our production to be more efficient.
Neste Oil aims to have capability to use only waste and residues in renewable diesel production by 2017. We have launched development projects at the Singapore and Rotterdam refineries to test whether waste and residual feedstocks of inferior quality can be utilized.
We have been able to significantly increase the usage of waste and residues. In 2014, waste and residues made up 62.0% (52.6) of the feedstocks of our renewable diesel.

We can use inferior animal and fish fat not suitable for human consumption and waste and residue streams of vegetable oil production, such as palm fatty acid distillate (PFAD). We procure waste feedstocks globally. In 2014, we expanded our waste feedstock range to include used cooking oil (UCO).
In 2014, we also tested the use of recycled lubricants as feedstock for traffic fuels. Previously, we have found that tall oil pitch is a suitable feedstock for traffic fuels. Tall oil pitch is waste whose utilization in the production of traffic fuels has not been possible until now; previously, it was disposed of through combustion. Neste Oil has a test license to utilize these raw materials until 2017.
Oil refining is highly efficient in terms of material usage, as virtually all raw materials used can be re-utilized. Crude oil can be utilized in a variety of ways, and a very small fraction goes to waste. The process also generates very little waste, as any product not meeting the quality requirements can be returned to the process and refined once more.
Material efficiency can be measured with the e-factor figure in which the weight of the waste generated is divided by the weight of the product output. The e-factor related to oil refining at Porvoo and Naantali refineries is under 0.01, while in the chemical industry, for example, the figure varies between 5 and 50. Similar efficiency is challenging to achieve in any other industry.
Neste Oil decided in 2014 to build a biopropane unit at its refinery in Rotterdam. The plan is to begin biopropane production by the end of 2016.
The biopropane production process utilizes sidestream gases from the production of NEXBTL diesel, from which propane will be separated for further use. Biopropane can replace the use of fossil fuels, thereby significantly reducing carbon dioxide emissions. The unit's biopropane production is expected to total 30,000–40,000 t/a. Biopropane is suitable for use in existing liquefied petroleum gas (LPG) applications. Neste Oil is the world's first company to make an agreement concerning the sale of biopropane.
