Waste fat from the fish processing industry Waste fat from the fish processing industry was introduced into NExBTL renewable diesel's raw material base in spring 2012.
- Waste fat is derived from gutting waste of fresh water cat fish pangasius after fillets have been removed for human consumption.
- The fish are farmed in Southeast Asia (e.g. Vietnam, Thailand, and Bangladesh)
- Fat content of the gutting waste is 30–35%.
- Waste fish fat can also be utilized in cosmetics and pharmaceutical industries.
- Bone meal produced from processing waste is used as raw material for animal feed.
- The use of waste fish fat for human consumption is limited.
- Waste fish fat from pangasius contains very little omega 3 or 6 fatty acids compared to the fat from seawater fish such as salmon.
- Chemicals and antibiotics used in fish farming accumulate in fat.
- Offers significant greenhouse gas savings: 84–88 %*.
- The batch of waste fish fat Neste Oil has procured complies with the strict sustainability requirements of the EU’s Renewable Energy Directive. The batch can be traced all the way back to the fish farm.
- Waste fish fat is also accepted as a raw material for renewable fuel in the US.
Detailed information about Neste Oil's use of renewable raw materials in the Sustainability Report 2011.
* Calculation is based on preliminary emissions figures covering the
various stages of the supply chain from the waste fish fat supplier in
Southeast Asia to Neste Oil’s Singapore refinery and from there to the
market in Europe, where fat sourced from fish processing industry is
classified as waste.
