HiProSUN Procedure
The HiProSUN process upgrades sunflower extraction meal – a low-value by-product of conventional sunflower oil production – into multiple high-value product streams.
During standard oil extraction, approximately 40 % sunflower oil and 60 % sunflower extraction meal are generated. HiProSUN utilises this extraction meal as a feedstock and converts it through a proprietary processing sequence into one primary high-protein product, one renewable energy carrier, and one protein-containing by-product, while ensuring efficient overall utilisation of the raw material.
The resulting product portfolio is designed for secure global availability, non-GMO supply chains, and high resource efficiency, even under volatile market or crisis conditions.
50%
High-Protein Fraction
HiProSUN I is the main protein fraction of the HiProSUN process.
It is characterised by a high protein content and is designed as a high-quality protein carrier for the animal feed industry.
35%
Pellets
HiProSUN II consists of separated sunflower seed shells that are processed into pellets.
These pellets serve as a renewable energy carrier for low-emission combustion and represent an alternative to wood pellets, without contributing to deforestation.
15%
Protein-Containing By-Product
HiProSUN III is a protein-containing by-product of the HiProSUN process.
Compared to HiProSUN I, it has a lower protein content, while still retaining nutritionally valuable components suitable for further utilisation in feed or industrial applications.
