“We have developed new technologies for the full recovery of residual streams from oil and fat refining”
The IRODDI initiative, led by TECNALIA, has developed new technologies to recover residual streams from oil refining
New bio-based products have been developed using the free fatty acids (FFA) contained in DODs (deodorisation distillates), generated as residual streams in the oil and fat refining process. These are the last steps in the process in which the compounds responsible for the bad smell, colour and taste of the oil are removed.
New high demand bio-products have successfully been obtained from these residual streams, such as:
- surfactants for green detergents
- biodegradable bio-lubricants
- bio-based polyols to formulate new polyurethanes
Work has also been developed on innovative technologies (extraction with super-critical CO2 and extraction with ionic liquids) for the isolation of valuable minor compounds contained in the DODs: characterised by using softer operational conditions than those used on an industrial level.
Replacement of fossil materials
The IRODDI project is a successful example of the direct application of the circular bioeconomy. It contributes to decarbonisation through the replacement of fossil-based materials with bio-based alternatives.
