Environmental Impact of Dross Management
TAHA’s innovative process sets a new standard in environmental responsibility by eliminating harmful practices associated with traditional dross processing.
Key Features of TAHA’s Environmentally Friendly Process
Elimination of Salt and Chemicals
TAHA’s process does not use salt or any other chemicals, unlike conventional rotary salt furnaces. This ensures that no toxic by-products are generated during aluminium recovery.
Avoidance of Hazardous Waste
Traditional methods produce "salt cake," a hazardous waste that is difficult to dispose of due to its environmental risks. Many regions, including Europe, have banned its disposal in landfills, requiring costly treatment facilities. TAHA eliminates this concern entirely.
Repurposing Residual
Oxides
The residual oxides from the process are not discarded. Instead, they are repurposed into valuable products such as Steel slag conditioners, Agricultural fertilisers, Heat-resistant outdoor tiles
Zero-Waste
Solution
By converting all residuals into feedstock for other industries, TAHA ensures a zero-waste process, aligning with global sustainability goals.
Comparison Between TAHA Method and Traditional Methods
TAHA's innovative approach to dross management outperforms traditional methods in several critical areas, setting a new benchmark for efficiency, cost-effectiveness, and environmental responsibility.
Criteria
Traditional Methods
TAHA’s Method
Energy Efficiency
High energy consumption due to rotary salt furnaces.
Low energy consumption with no additional energy inputs required.
Use of Chemicals
Requires salt and other chemicals, producing hazardous “salt cake.”
Eliminates the use of salt or chemicals, ensuring a clean process.
Environmental Impact
Produces “salt cake,” classified as hazardous waste, requiring costly disposal.
Zero-waste solution that repurposes residual oxides for various applications.
Aluminium Recovery
Limited recovery rates, leaving significant aluminium in the dross.
Recovers up to 90% of aluminium in the first stage and most of the remaining aluminium in the second stage.
Cost-Effectiveness
High operational costs due to energy use, chemicals, and waste treatment.
Cost-effective by reducing energy use, eliminating chemicals, and simplifying waste management.

Residuals
The residual oxides from TAHA’s process are converted into feedstocks for various downstream applications. These include Steel Slag Conditioners, Agricultural Fertilisers, and Aluminium Trihydrate (ATH). This ensures no waste is left behind, making the process completely sustainable and beneficial for multiple industries.
