摘要:
Cement constitutes one of the major materials used for the construction of buildings. In 2011, the cement output of China reached 2.06 billion tons, which accounts for over 50% of the total cement output of the world. Meanwhile, more than 230 million tons industrial waste and domestic waste are beneficial used as raw materials in cement production each year, which results in a decrease in the total raw materials and energy demands and prevents a large amount of land use for landfill or surface impoundment. The objective of this study is to analyze the environmental impact caused by beneficial use of domestic waste in Chinese cement industry. Subsequently, the environmental burdens of five routes of domestic waste treatments, including landfill, incineration, beneficial used by cement production, etc, are quantified one by one using life cycle assessment methodology. The results demonstrate that the beneficial use of domestic waste has a great potential to decrease the environmental impact caused by waste treatment, especially to lower human toxic impact.
