The main environmental protection issues related to ceramic fiber production include air pollution from emissions of dust and toxic gases, water pollution from wastewater discharge, and solid waste generation. The production process can release particulate matter and harmful gases such as sulfur dioxide and carbon monoxide, contributing to air quality degradation. Additionally, wastewater from the manufacturing process can contain heavy metals and chemicals, posing risks to aquatic ecosystems. Lastly, the disposal of solid waste from production, if not managed properly, can lead to soil contamination and other environmental hazards.
