Recycling
3Rs (Reduce, Reuse, Recycle), Eco-friendly Waste Management StrategiesThanks to its constant efforts to recycle waste, such as wafers, waste chemicals and sludge from the production process, SAMSUNG Electronics' Semiconductor Division now recycles (including energy recovery) 92% of all the currently generated waste. It also tries to minimize waste generation by improving production processes, reducing the amount of chemicals used in production and using self-treatment technology. In recognition of these efforts, the company was designated as exemplary in terms of waste reduction in 2007 and was awarded the Grand Prix for Recycling by the Minister of Commerce, Industry and Energy.
In addition to the 3R activities, SAMSUNG Electronics' Semiconductor Division has adopted an unmanned measurement system and the government waste management system to improve the transparency of its waste management system.
| Reduce | - Waste remains in containers have decreased because of the shift in chemicals supply from the centralized supply to the individualized supply, and bigger containers, such as tank trucks. |
|---|---|
| Reuse | - A new process aimed at reusing parts of wasted machines has been established. - The introduction of the slurry treatment system into the CMP process has decreased the amount of slurry waste. |
| Recycle | - Recycle some sulfuric acid waste in the scrubber on the roof of the company building and the wasted water treatment facility. - Refine wasted chemicals to reuse them for products or fuel in other industries. - Recycle synthetic resins into materials to be used in the production of plastics. - Recycle wasted steel into materials to be used in the production of related products. - Wasted wafers are recycled into highly-purified silicon to be used as materials in the production of solar cells, which is considered as an effective response to global warming. |
