In 1975 the brown seaweed, Ecklonia maxima, is identified as having beneficial effects on plant growth. The quest begins to develop an effective cellular-level extraction technology to access its active elements.
A pressure differential extraction process is developed without heat, freezing or chemical digestion. This later becomes the famous Cellburst® technology, preserving the natural compounds found within Ecklonia maxima.
Cellburst patents are registered internationally and the Kelpak story officially begins, initially serving the South African agricultural and home garden markets.
Commercial manufacturing expands as the pioneering extraction technology moves from development into production, laying the foundation for decades of scientific innovation.
The first doctoral thesis on Kelpak is published by the University of KwaZulu-Natal, confirming its beneficial properties on crops.
