In a circular economy, products, waste, and resources are kept in the system as long as
possible. This review aims to highlight the importance of cold plasma technology as an alternative
solution to some challenges in the food chain, such as the extensive energy demand and the hazardous
chemicals used. Atmospheric cold plasma can provide a rich source of reactive gas species such as
radicals, excited neutrals, ions, free electrons, and UV light that can be efficiently used for sterilization
and decontamination, degrading toxins, and pesticides. Atmospheric cold plasma can also improve
the utilization of materials in agriculture and food processing, as well as convert waste into resources.
The use of atmospheric cold plasma technology is not without challenges. The wide range of
reactive gas species leads to many questions about their safety, active life, and environmental impact.
Additionally, the associated regulatory approval process requires significant data demonstrating
its efficacy. Cold plasma generation requires a specific reliable system, process control monitoring,
scalability, and worker safety protections.
