Waste and material management


Waste management at Cemig is undertaken in accordance with established corporate procedures for the handling, separation, labeling, temporary storage, transport, baling and final destination of waste.

The areas generating the waste are responsible for all the steps prior to the transportation of the waste to the Materials Distribution Center. Upon being received at this facility, the waste is temporarily stored, classified and separated for alienation and final disposal. Compliance with environmental legislation is verified and controlled throughout the entire industrial waste management process.

In 2010, of the waste disposed of, 2,438t were classified as non-hazardous, in accordance with Brazilian Technical Norm NBR 10004/2004 and sent for recycling and reuse, which represents 68% of the total waste generated by the Company.

Regarding hazardous waste, the Company correctly disposed of 1,1670t, with 265t being coprocessed or incinerated and 895t being sent for recycling/reuse. Of this total, 155t of insulating mineral oil removed from electrical equipment were regenerated and utilized by the company itself. The waste sent for coprocessing included 252t of waste impregnated with oil (gloves, rags and sawdust) and 1.7t of PPE and accessories and 11t of insulating mineral oil inadequate for use in electric equipment was sent for incineration.

680,000 fluorescent and public lighting lamps were sent for recycling throughout the Company’s concession area, as were 256,000 incandescent lamps.

3,333 tonnes of material and equipment were alienated /recycled. This figure is 18.5% lower than in 2009 due to a reduction in the generation of retired transformers, scrap metal, scrap meters, reactors and batteries. There was also a reduction in the alienation of various oils.
