About EF Polymer
Manufacturer of natural water retention polymers intended to mitigate the problems of water scarcity. The company's polymers are developed based on organic waste such as citrus fruits, banana peels, and sugar cane bagasse that absorb water in huge amounts and then release it as plant requirements, enabling farmers to use it in the form of fertilizers and reduce irrigation water requirements.
