About EF Polymer

EF Polymer is a Japanese company that has developed a 100% organic and biodegradable super-absorbent polymer. The product is created from organic waste, primarily fruit peels such as oranges and bananas.

The company's primary market is the agricultural sector. Its polymer is designed to be applied to soil to help retain water and nutrients. This leads to a reduction in the amount of water and fertilizer needed for crops, which in turn can lower costs and increase profits for farmers. The product aims to address challenges like water scarcity and soil degradation in agriculture.

EF Polymer operates on a B2B business model, selling its polymer directly to farmers, growers, and potentially agricultural suppliers. The company has reported sales of 400 tons, indicating a growing customer base and market traction. While the primary focus is on agriculture, the company has also unveiled biodegradable thickeners for the cosmetics industry, suggesting a potential diversification of its product applications and revenue streams.
