Tackling acid mine drainage and heavy metal migration requires an integrated approach. BGRIMM’s synergistic technology combines source control, migration barriers, and ecological remediation to sustainably rehabilitate metal mine and coal gangue waste piles.

How it works:

1. Source Control: Chemical-microbial materials suppress acid generation by over 85%, raising leachate pH above 6.0.

2. Migration Barrier: Engineered capillary and compacted cover systems isolate oxygen and precipitation; modified bentonite GCL barriers control contaminant spread.

3. Active Remediation: Permeable reactive walls treat leachate; stabilization reduces heavy metal activity in soil.

4. Ecological Recovery: Plant-microbe restoration achieves >90% vegetation coverage, transforming the site into a stable landscape.

Proven Results:

1. Heavy metal leaching reduced by >90%

2. Sustainable vegetation coverage >90%

3. Demonstrated at copper, lead-zinc, and coal gangue sites

A turnkey, measurable solution for mine site rehabilitation and closure.
