Funding to support sustainable water solutions, global scale-up, and new product development across agriculture and beyond

‍

Okinawa, Japan - EF Polymer, a deep-tech startup developing 100% organic super absorbent polymers, today announced that it has raised JPY 1 billion (approx. USD 6.6 million) in the first close of its Series B round through a third-party allocation of shares.

Founded with a mission to solve global water challenges and improve farmers’ livelihoods, EF Polymer has created a bio-based alternative to petroleum-derived absorbents, helping reduce water and fertilizer use in agriculture while improving yields. Its proprietary materials are also expanding into non-agricultural applications such as cosmetics, personal care, and cold chain solutions.

Accelerating Global Growth

Since launching sales in India in 2020, EF Polymer has delivered products to farmers across Japan, the U.S., and France, achieving over 400 tons in cumulative sales by 2025. Amid rising concerns over drought and fertilizer costs driven by climate change, global demand continues to rise, with commercial trials and partnerships now underway in over 20 countries. To meet this demand, the company plans to strengthen operations in key markets while expanding into new sectors such as horticulture, landscaping, and urban greening.

Driving Green Transformation in New Industries

EF Polymer is also scaling its presence in non-agricultural markets. Recent projects include a biodegradable ice pack Cy-Cool, co-developed with Iwatani Corporation, and absorbent sheets in partnership with Soken Chemical. Its polymer solutions offer a sustainable alternative to petroleum-based ingredients commonly used across industries, contributing to the green transformation (GX) of everyday products.
