Abstract

Urbanization, agricultural practices and industrial waste have contributed to all environmental pollution, which has become a great concern worldwide, especially when it comes to this air quality aggravated, waste water pollution and constant organic pollutants. Traditional therapeutic techniques, including absorption, ozonation and chlorination, are often associated with high energy costs, inadequate environmental toxins and the production of dangerous underpaths. Given this, cold atmospheric plasma (CAP) has gained popularity in the form of a non-thermal, adaptable and durable technology that can produce a variety of reactive oxygen and nitrogen species (RON) for effective processing. With air purification, wastewater treatment and use of the use in frequent pollutants, this article provides a complete summary of CAP's environmental applications. Advanced oxidation procedures driven by reactive species with short and expanded half -life include the discussion of underlying plasma macology that removes contaminants. In addition, the recent CAP integration is emphasized with hybrid systems as a means of improving efficiency and reducing energy consumption in CAP integration. Relevant problems are strictly investigated, such as security problems, economic viability and scalability. Lastly, future prospects regarding CAP's potential as a game-changing instrument for environmentally sustainable management are discussed.
