Management of Solid Waste Containing Fluoride-A Review

Area of Science:

• Environmental Science
• Materials Science
• Chemical Engineering

Background:

• Industrial development generates significant post-production waste, including hazardous materials.
• Waste materials, especially those containing fluoride, pose environmental and health risks.
• Current utilization of waste in construction materials is limited, necessitating innovative solutions.

Purpose of the Study:

• To review methods for removing excess fluoride from drinking water and industrial wastewater.
• To assess the potential of various waste materials, including industrial by-products, agricultural waste, and biomass, for fluoride absorption.
• To highlight the importance of reusing fluoride-containing solid waste.

Main Methods:

• Comprehensive literature review of existing fluoride removal technologies.
• Analysis of studies on the use of waste materials for construction.
• Evaluation of adsorbent materials for fluoride capture from aqueous solutions.

Main Results:

• Solidification/stabilization processes enable the use of hazardous and non-hazardous waste in construction materials.
• Various industrial by-products, agricultural wastes, and biomass show potential for fluoride absorption.
• Effective technologies for fluoride removal from water are critical due to its environmental and health impacts.

Conclusions:

• Reusing fluoride-containing waste in construction materials is a high-priority environmental goal.
• Adsorbent materials derived from waste offer a promising avenue for water remediation.
• Further research is needed to optimize waste utilization and fluoride removal technologies.
