YENXA, FROM USED COOKING OIL TO SOAP

Sergio Villava

Managing Partner&Cofounder at YENXA

Noain, Spain

About

YENXA Home is a circular‑economy home appliance developed by Almotech that transforms kitchen oil waste—one of the most common household pollutants—into high‑quality laundry detergent. With a simple jar, water and pre-dosed biodegradable capsules, the user can turn one liter of oil into enough soap for dozens of washing cycles, eliminating plastic packaging and reducing water contamination..

YENXA Professional brings that same patented technology to scale. Designed for use in hotels, residential communities, rural resorts or shared kitchens, it delivers fast, automated soap production at minimal cost—directly at source. Its robust design, quick operation, and sustainable impact support operations seeking tangible RSC and environmental innovation. YENXA fosters measurable circularity, reducing the carbon footprint of used oil disposal, saving costs, and reinforcing brand value with eco-conscious users.
