Samsarapps s.l (SOUJI)

Souji is a circular economy company that has developed a unique technology capable of transforming used cooking oil into sustainable cleaning products—quickly, safely, and effectively. Our solution operates through three business models: B2C, where households create their own cleaner at home; B2B on-site, with machines adapted for hotels, cruises, and catering; and a decentralized industrial model, through partnerships with local labs and operators.
Backed by certifications (REACH, CE, LCA, carbon footprint) and validated by institutions such as the Basque Culinary Center and global hotel chains like Hilton, Marriott, and Blaumar, Souji not only reduces costs and waste but also promotes sustainability, water savings, and CO₂ reduction—contributing to a cleaner, more responsible future.
