Waste
(GRI EN22)
CTEEP has five temporary waste storage facilities in operation, one in each Regional Department. This allows having larger amounts for final waste disposal, waste separation and segregation, with an economic benefit, in addition to ensuring that waste is stored properly until final disposal through a specialized accredited company. In 2013, CTEEP disposed of the following amounts of waste stored in these sorting and storage facilities.
| Waste | Weight (kg) | Disposal method |
| Materials contaminated with oil or paint | 8,209 | coprocessing |
| Lubricant oil and insulating oil | 2,651 | coprocessing |
| Asbestos (material made of asbestos cement) | 1,795 | Class I landfill |
| Rubber and tire scrap | 407 | coprocessing |
| Polypropylene foam scrap | 0 | coprocessing |
| Nickel/cadmium batteries | 12 | incineration |
| Dry batteries (non-recyclable batteries) | 140 | incineration |
| Fluorescent lamp ballasts | 349 | coprocessing |
| Gas-discharge lamps (metal halide, sodium-, mixed-, mercury-vapor and fluorescent lamps) | 2,570 | recycling |
| Asbestos | 5,180 | Class I landfill |
| Ink cartridges | 104 | incineration |
| Glass | 61 | coprocessing |
| Chemical products for cleaning parts (with water) | 16,130 | incineration |
| PCB disposal | 198,255 | incineration |
The waste above is produced by energy transmission activities and causes considerable environmental impact as the Company sees it. The disposal methods were based on the damage potential of each item, the prevailing legislation (which required, for example, analyses and reports about the waste and authorizations to transport environmentally-sensitive waste), the techniques available on the market and the costs.
It is worth noting that the Company regenerated 636,300 liters of insulating mineral oil, used to as a coolant and dielectric insulator in equipment like transformers and circuit breakers. This initiative reduced the need to buy this material, thus leading to savings and lower environmental impact.
In addition, CTEEP's administrative headquarters generated 11,160 kg of potentially recyclable waste, sorted through selective waste collection. After being processed and sorted, 4,465 kg of waste, including plastic, paper, metals and glass, was recycled.
