Turning environmental challenges into profitable, planet-positive mining solutions.
TURNING MINE WASTE INTO GREEN VALUE
BacTech Environmental Corporation’s Zero Tailings™ initiative transforms residual mine materials into high-value, sustainable products—creating new revenue streams while advancing global environmental goals.
BacTech Environmental Corporation is advancing its Zero Tailings initiative, designed to transform mine waste into high-value green commodities while promoting sustainable mining practices. As of June 18, 2025, BacTech filed a provisional patent application to expand its Zero Tailings processing technology beyond traditional bioleaching. This builds on a full patent application submitted in April 2025, which focuses on treating iron and acid streams generated during bioleaching operations.
The Zero Tailings process converts mine waste into valuable products, including high-purity magnetite iron, ammonium sulphate fertilizer, and base metals such as nickel, copper, and cobalt. By doing so, the technology not only aligns with global sustainability objectives but also creates new revenue streams and reduces dependence on conventional mining methods.
Designed for adaptability, BacTech’s technology can be applied to a variety of mineral processing scenarios, including treatment of acidic runoff from legacy mine sites. This capability opens opportunities for recovering metals from low-grade material that would otherwise remain untapped. Over the next year, the company plans to engage industry partners to further test, refine, and scale the technology, demonstrating its potential to deliver both environmental and economic benefits.
BacTech’s Zero Tailings initiative represents a forward-looking approach to responsible resource management, combining innovation, sustainability, and commercial potential to redefine how the mining sector treats its residual materials.
What it Delivers
-
Recovered iron is repurposed for use in construction and manufacturing, reducing reliance on newly mined materials and lowering the carbon footprint of steel production.
-
High-grade nickel is extracted from waste sources, providing a sustainable supply for electric vehicles, batteries, and stainless steel — key components in the clean energy transition.
-
Essential nutrients are reclaimed and converted into eco-friendly fertilizers, supporting regenerative agriculture and closing the loop between industry and the environment.
-
Treated process water is purified and recycled, minimizing freshwater use and helping to restore balance in local ecosystems affected by industrial activity.
-
Non-toxic byproducts are transformed into safe, durable aggregates for roadways and construction — turning what was once waste into lasting infrastructure.
Environmental & Social Benefits
BacTech prioritizes safety and environmental responsibility, particularly through its bioleaching technology. This process uses naturally occurring bacteria to treat mining waste, which is safe for both humans and the environment. The bioleaching method also stabilizes harmful elements, such as arsenic, by converting them into benign forms like ferric arsenate, approved for landfill disposal by the US Environmental Protection Agency.
The environmental benefits of BacTech’s technology include:
No Harmful Emissions: The process is water-based, eliminating the need for roasting or smelting, which can produce harmful gases.
Green Chemistry: Utilizes ammonia instead of acids or exotic chemicals, reducing environmental impact.
Zero Waste Initiative: Converts mine waste into valuable products, such as metals and fertilizers, reducing the need for fresh mining and lowering global emissions.
BacTech’s commitment to safety and environmental standards is evident in its efforts to provide sustainable solutions for mining waste management, fully aligning with global sustainability goals.
