for batteries instead of recycling them ourselves. Changes in vendor requirements, regulatory requirements that affected vendors and the company’s power-line maintenance programs accounted for reductions in the other categories.

During the past ten years, TXU has recycled more than 13.7 billion pounds of materials, including 12.7 billion pounds of coal combustion products, 660 million pounds of wood products, 177 million pounds of scrap metal, 62 million pounds of drained electrical equipment, 30 million pounds of insulating oil and 4 million pounds of paper and aluminum.

USING RECYCLED PAPER
In addition to our recycling efforts, we also promote the use of recycled products. Each year, we use recycled paper to print various customer information pieces, brochures and annual reports – including this Environmental Review.

COAL COMBUSTION PRODUCTS
As has been the case for the past 10 years, the recycling of more than 2.2 billion pounds of coal combustion products – fly ash and bottom ash – from our Big Brown, Monticello, Martin Lake and Sandow generating plants accounted for the largest quantity of material recycled during the year. TXU has been instrumental in the development of commercial markets for various types of ash that remain after burning coal for electric generation. Most of the combustion products sold during the year were used as a cement substitute in ready-mix concrete for highway, bridge and building construction. The reuse of this existing material saves energy costs and reduces greenhouse gas emissions by replacing raw materials in cement manufacturing and saving landfill space that would otherwise be used to dispose of the product.
