About

Founded in 2020, SMALLOPS is a limited company headquartered in Don Benito, Spain with approximately 11-50 employees specializing in Biogas, Other.

SMALLOPS is a technology-based company specializing in sustainable nanoenergy solutions. The company produces carbon-encapsulated zero-valent iron nanoparticles (OPS) derived from olive oil waste through hydrothermal carbonization. These nanoparticles are used to enhance biogas and biomethane production in anaerobic digestion processes, improving methane yield by 10-20%, reducing hydrogen sulfide formation, and optimizing digestor stability. SMALLOPS also develops water treatment solutions and agricultural products from agro-industrial residues, operating on a zero-waste circular bioeconomy model. The company provides laboratory services, R&D, biogas plant design and engineering, and technical support for biogas plant optimization.
