olivair

Olivair is a term used in environmental technology to denote systems and products that use olive-derived materials to improve air quality. The concept rests on the idea that byproducts from the olive industry, such as olive pits and leaves, can be converted into functional filtration media and catalyst components.

Technology in Olivair designs typically combines sorption media made from olive-pit activated carbon or olive-leaf lignocellulosic structures with conventional filtration, and in some designs, photocatalytic components to break down pollutants. These devices aim to capture volatile organic compounds, odors, and particulates, with optional regeneration methods that reuse heat, solar energy, or vacuum cycles to extend the media’s lifespan.

Development of Olivair concepts emerged in Mediterranean research contexts during the 2010s as part of waste valorization and circular economy initiatives. Pilot studies have tested Olivair modules in residential settings, classrooms, and greenhouse environments to assess removal efficiency, longevity, and lifecycle costs.

Applications of Olivair technologies are most favorable where olive byproducts are abundant and energy costs for regeneration are manageable. They are presented as alternatives or supplements to conventional filtration, potentially reducing reliance on synthetic media; however, they face challenges related to material consistency, regeneration energy requirements, and cost at larger scales.
