Mine Remediation
From active operations to legacy cleanup — biological solutions that reduce costs and achieve superior contaminant removal
From active operations to legacy cleanup — biological solutions that reduce costs and achieve superior contaminant removal
Mining operators face mounting pressure from rising chemical treatment costs, increasing sludge disposal liability, and tightening environmental compliance requirements. Traditional methods often create secondary waste streams and require hazardous reagent handling—adding complexity and risk to operations.
Our integrated biologic + biochar approach neutralizes contaminants, stabilizes mine-impacted soils, and restores biological activity — with no toxic byproducts, no chemical sludge, and 20–50% lower cost than traditional chemical methods.
Biochar's high surface area adsorbs and immobilizes dissolved metals while specialized microbes precipitate them into stable solid forms — together reducing mobility and bioavailability.
Biochar stabilizes pH and adsorbs acid-generating compounds while biological sulfate reduction processes neutralize acidity and precipitate metals — treating AMD at the source rather than downstream.
Biochar amendments stabilize tailings structure and sequester carbon while active microbial consortia degrade sulfide minerals, reducing oxidation and acid generation potential.
Biochar filters and adsorbs contaminants while biological processes improve pH, reduce dissolved solids, and remove dissolved metals to meet discharge standards.
Biochar-based treatment cells provide permanent physical structure and long-term carbon sequestration, supporting low-maintenance biological remediation with minimal ongoing operational costs.
Biochar improves soil structure and long-term water retention while biological treatments restore soil biology, creating conditions favorable for vegetation and full ecosystem recovery.
Independent laboratory analysis of gold mining pregnant solution. Our integrated biologic + biochar treatment achieves significant reductions across all tested contaminants — with biochar providing initial adsorption and stabilization, and our microbial consortia delivering sustained biological breakdown.
Biochar alone delivers meaningful heavy metal and cyanide adsorption. When paired with our microbial consortia, results are significantly amplified — biologics colonize the biochar matrix and continue breaking down contaminants long after initial adsorption is saturated.

Abandoned mine sites across the country leach heavy metals into watersheds. Our low-cost, zero-sludge approach opens new pathways for cleanup.
The federal Good Samaritan Remediation Act (signed December 2024) creates liability protections for nonprofits and agencies who clean up historic mine sites. We help you take advantage of this new pathway.
Traditional remediation costs make abandoned site cleanup economically impossible. Our integrated biologic + biochar approach changes the math — biochar stabilizes soils and sequesters carbon immediately, while our microbial consortia actively neutralize contaminants over time.
