Key Challenges
Health and Safety Concerns During Handling
Chlorine dioxide poses handling risks due to its strong oxidizing nature and potential for instability in high concentrations. Improper storage or mixing can lead to hazardous conditions, prompting the need for strict operational controls. Companies must comply with safety regulations and invest in advanced containment systems. This adds to production and maintenance costs, creating a barrier for smaller manufacturers.
High Production and Operational Costs
The cost of chlorine dioxide generation and storage remains high compared to traditional disinfectants. Complex equipment requirements and specialized material compatibility contribute to elevated capital expenses. Additionally, operational costs rise due to the need for continuous monitoring and technical expertise. These factors can limit adoption in cost-sensitive industries, especially in developing economies.
