Neste uses wide variety of sustainable, globally-sourced raw materials each year to produce its renewable products. The majority of these are wastes and residues. Used cooking oil, animal and fish fat waste, and various wastes and residues from vegetable oils processing represent the largest three waste and residue raw material categories we use based on their current and estimated shares of Neste’s total annual renewable raw material inputs.
Neste has focused on waste and residue raw materials for over a decade, and in the first half-year of 2021, the share of waste and residues increased to 92% of Neste’s total renewable raw material inputs globally. Our refineries of renewable products have been technically capable of running on 100% waste and residues since 2015. In the mid to longer term, we expect to also use other types of raw materials, such as novel vegetable oils that are based on advanced cultivation practices.

Reducing emissions while accelerating the circular economy
With our proprietary NEXBTL™ technology, renewable products can be refined flexibly from a wide variety of low-quality raw materials while the end products retain their high quality.
Efficient utilization of wastes and residues is one of the cornerstones of the circular economy. Producing high-quality products from waste and residue raw materials is an example of efficient use of resources. It also provides one of the key means to reduce the pressure to clear new areas of land for the cultivation or production of virgin raw materials for various uses.
The life cycle emissions of products produced from waste and residues are also typically smaller than those produced from virgin vegetable oils, and significantly smaller than lifecycle emissions of fossil oil based alternatives.

Exploring new wastes and residues
Neste invests heavily in innovation with 25% of our workforce employed in R&D. We are continuously searching for even lower quality wastes and residues to be used in the production of fuels, chemicals and other materials. We are developing the availability of emerging, even lower quality waste and residue raw materials, such as municipal solid waste, lignocellulosics, algae and power-to-liquids.
