EF Polymer: A 100% Natural Super Absorbent Polymer Made from Crop Residues

EF Polymer is a 100% natural super absorbent polymer upcycled from agricultural residues such as orange and banana peels that were traditionally discarded.

Simply mix it in—your soil changes.

EF Polymer absorbs water and nutrients from rain/irrigation and slowly releases them as the soil dries, extending moisture availability. It helps improve water & nutrient retention, supports healthier soil by promoting microbial activity, encourages soil aggregation/porosity through repeated absorb–release cycles, and is fully biodegradable—effective for about 6 months, then gradually decomposes and returns to the soil in roughly one year.

Performance & Results

This panel showcases field results demonstrating EF Polymer’s benefits in water retention, nutrient retention, yield stability, and cost-effectiveness. Examples include: cabbage in Aichi showing smoother establishment/early growth and +300 g per head on average (1670 g → 1985 g); pineapple in Okinawa shortening the cultivation period from ~3 years to ~1.5 years while maintaining comparable fruit weight and sweetness; sweet potato in Hokkaido with ~40% more harvested roots, ~20% higher large-size ratio, and ~50% higher average weight; and cabbage in Okayama reducing heat-related yellowing, achieving a 12% loss reduction and an estimated +¥50,000 improvement in economic return.
