Approximately 30% of proposed mineral extraction projects experience delays due to environmental impact assessments and land restoration requirements. In addition, nearly 20–25% of diatomite deposits contain impurities such as clay, sand, or quartz exceeding 10–15%, which requires additional processing and purification before industrial use. Calcination processes used to produce filter-grade diatomite operate at temperatures above 900°C, leading to high energy consumption and emissions. Regulatory standards for silica dust exposure have also tightened in many industrial regions, resulting in nearly 35% of diatomite processing facilities installing advanced dust-control systems and workplace monitoring technologies, increasing operational costs and slowing the approval of new mining projects.

Expansion in organic agriculture and natural pest control

Opportunity

A major opportunity highlighted in the Diatomite (Diatomaceous Earth) Market Outlook is the rapid expansion of organic agriculture and natural pest control solutions. Globally, certified organic farmland exceeds 72 million hectares, with more than 3 million organic producers operating across 180 countries. Diatomaceous earth is widely used as a natural insecticide because its microscopic silica particles damage insect exoskeletons and cause dehydration. Nearly 40% of global grain storage facilities use mineral-based pest control solutions to protect stored crops from pests such as beetles, mites, and weevils.

Storage insects cause losses of approximately 8–10% of global grain supplies, affecting more than 500 million tons of stored grains annually, which increases demand for effective pest control materials. In addition, the livestock sector increasingly uses diatomite in poultry farms and cattle housing, where nearly 25% of natural parasite control products contain diatomaceous earth. These trends create strong growth opportunities for diatomite producers targeting agricultural and eco-friendly product markets.

Availability of alternative filtration materials

Challenge
