HiProSUN is a German clean-tech company focused on unlocking the hidden value of sunflower oil production byproducts. During the production of sunflower oil, sunflower extraction meal and expeller accumulate in oil mills—materials that are not waste but rich in high-quality nutrients. Using the proprietary HiProSUN process, these residues are further refined into high-protein animal feed suitable for both mono- and polygastric animals as a sustainable, non-GMO alternative to soy meal, while also serving as a source of green energy.
