Segmentation by Product Type

The high purity diatomaceous earth market features two primary product grades with distinct characteristics:

1. Food Grade Diatomaceous Earth

Food grade diatomaceous earth meets stringent purity standards for human consumption applications, with maximum limits on heavy metals and crystalline silica content. It’s primarily used as processing aid in beverage filtration and food additive applications.

• Market Insight: Food grade accounts for approximately 62% of the market by value, driven by global beverage industry demand. Its heat resistance and filtration efficiency make it ideal for beer, wine, and juice clarification.

• Trend: The craft beer revolution in North America and Europe has created new opportunities, with microbreweries increasingly adopting D.E. filtration for superior clarity and flavor preservation.

2. Filter Grade Diatomaceous Earth

Filter grade offers superior porosity and particle size distribution for challenging industrial filtration applications, particularly in water treatment and chemical processing.

• Market Insight: This segment is growing at 6.1% CAGR, outpacing food grade. It’s finding new applications in swimming pool filters and pharmaceutical manufacturing where absolute filtration is critical.

• Trend: Water scarcity concerns are driving innovation in municipal water treatment plants, with engineered filter grades gaining traction for their ability to remove sub-micron particulates.
