KESSLER team of scientists and researchers is keen to share crucial findings from our work on KESSLER elite varieties of the Pongamia tree cultivated explicitly for use in degraded and desert terrain. We will present and resemble the quality of inedible Pongamia oil obtained from two distinct genetic varieties grown in our pilot plantation in the Negev desert.
Our focus lies solely on our elite varieties designed for extreme desert conditions, as they demonstrate exceptional qualities, including the highest yield per hectare and the production of top-quality products.
While we have conducted tests on numerous other genetic varieties grown in diverse regions with varying soil and climatic conditions, the substantial differences in quality and suitability for biofuel production require a cautious and equitable view.
Our prime two generics are called 5781-A and 5781-B
To ensure rigorous analysis, we examined both KESSLER Pongamia varieties oils in three independent laboratories across different countries. The evaluations encompassed physicochemical parameters, heavy metal content, and fatty acid profile analysis to discern the structural distinctions between the oils.
Both types of Pongamia oil are characterized by excellent quality parameters, confirmed in the laboratory. Regarding sulfur content, the oil from the 5781-A genetic variety turned out to be slightly better - The sulfur content is below 2 ppm, and in the 5781-B variety, it is at 5 ppm. Both grades A and B practically do not contain heavy metals in their composition, which significantly impacts the lifetime of catalysts in HVO processes. Both grades are characterized by excellent stability to low temperatures (a fundamental property in storing these oils), and low FFA content (in the case of 5781-A, it is the level of 0.7%).
Undoubtedly, one of the essential advantages of KESSLER elite varieties of the Pongamia tree is the supply of stable, top-quality inedible oil for fuel and energy processes.
A noteworthy contrast emerges when comparing the fatty acid profiles of the two varieties. The C16 palmitic acid content is comparable, approximately 9.4-9.5%, signifying its suitability for biofuel production, as it affects the finished biodiesel's Cold Filter Plugging Point (CFPP).
In terms of C18 stearic acid content, the 5781-B variety demonstrates a slightly higher concentration at 8.8%, while the 5781-A variety contains 6.9%.
The most significant distinction arises in the content of C18.1 oleic acid, with the 5781-B variety containing 55.89% and the 5781-A variety having 44.73%.
Regarding C18.2 linoleic acid, the difference is minor, with the 5781-A variety at 24% and the 5781-B variety at 22%.
The conclusion derived from independent research bodies is clear - Pongamia oil from varieties 5781-A and 5781-B are outstanding raw materials for the HVO process, renewable diesel production, and SAF (Sustainable Aviation Fuel).
The elite varieties of the Pongamia tree, developed by KESSLER, provide a stable supply of top-quality inedible oil for fuel and energy processes, highlighting their paramount significance in feedstock development.
As KESSLER, we firmly believe that every company must strive to achieve zero emissions and adopt environmentally friendly practices. Our commitment to feedstock development and law-carbon oil production boosts our mission to enable a zero-emission economy.
By advancing the utilization of our elite varieties of the Pongamia tree for biofuel production, we actively contribute to reducing greenhouse gas emissions and promoting sustainability.
