Waste Management

Dry Stack Method for Nickel Tailings and Nickel Slags Disposal

Similar to other processing industries in general, the waste from nickel ore processing is a matter that has to be properly managed. The nickel tailings and slags produced from our nickel ore processing plants have undergone characterization and toxicity tests in accordance with Indonesia's Regulations. The results are shown as non-corrosive, non-reactive, non-toxic, non-flammable, and non-explosive waste. However, due to the huge volume of waste, we are committed to manage any potential environmental and social impacts. 

TBP's approach to managing waste is the "3R principle" (reduce, reuse, recycle). We reuse the wastes to produce concretes and bricks, and use them as the building material for our facilities such as buildings, camps, and paving roads.

TBP DO NOT USE DSTP/DEEP SEA TAILING PLACEMENT. Instead, we opt to take advantage of the proximity of our mine site and processing plant by backfilling the nickel tailings and slags into the mined out mining pits. This method is better known as the Dry Stack Method. By using this method, not only does TBP can reduce the earth material required for backfilling, the tailings and slags from the processing plant can also be safely disposed of and closely monitored. The Dry Stack Method is recognized internationally as one of the safest method for waste management.
