What many see as waste, we see as valuable raw materials
At Neste, we are constantly looking to diversify our portfolio with new raw materials. Neste uses a wide variety of globally-sourced renewable raw materials to produce renewable products. The majority of renewable raw material inputs consist of waste and residues, while a smaller percentage of various vegetable oils can also be used. The top 3 renewable raw material categories used annually are animal fat waste, used cooking oil and different wastes and residues from vegetable oil processing. The proportions of the individual raw materials vary year to year, and from market to market, depending on availability, price, and market-specific requirements.
Purifying raw materials
The waste and residue materials are pre-treated to remove impurities. This creates a clean raw material that can be turned into renewable products.
Refining is the last step
To produce diesel molecules, oxygen originating from renewable raw materials needs to be removed with the help of additional hydrogen. Other impurities, like sulfur, are also removed during this process. Hydrocarbons are then isomerized to fine-tune the properties of the end products into renewable diesel. During this process, the hydrocarbon structure is branched to create the desired properties, a unique element of our proprietary NEXBTL technology.
