Ecogranular

Granada ·Pre-seed

Ecogranular (Ecogranular Technologies S.L.) is a University of Granada spin-off that has developed a continuous-flow aerobic granular biomass process for biological wastewater treatment, removing organic matter, nitrogen and phosphorus in a single reactor. The technology cuts plant footprint, sludge generation and operating costs while improving effluent quality, and builds on the LIFE ECOGRANULARWATER project (LIFE16 ENV/ES/196) run by UGR's Institute of Water Research. In May 2024 it raised €174,000 from deep-science fund BeAble Capital, and it was an award winner for Sustainable Entrepreneurship in UGR's XIII University Entrepreneurship Competition; it also pitched at Alhambra Venture 2026 in Granada.

Gradiant

United States · www.gradiant.com ↗

Sells its own wastewater treatment process technology and plants to utilities and industrial water users, aiming for lower footprint, lower operating cost and better effluent quality, the same pitch Ecogranular makes.

Emefcy

Israel · www.fluencecorp.com ↗

Commercialised a new biological wastewater treatment process (MABR) that removes nitrogen at lower energy and footprint, and sells it to municipal and decentralised plants.

Organica Water

Hungary · www.organicawater.com ↗

Licenses and builds its own compact biological treatment process (fixed-film biomass) for municipal plants, cutting footprint and operating cost the way aerobic granular sludge does.
