| Sammendrag: | This report mainly talks about utilizing the cement kiln to dispose wastes. In China, there are huge
amounts of wastes can be produced every year. China government pays more attention to the
environmental protection. The government wants to dispose the wastes securely. The cement kiln is a
good ‘place’ to take the wastes. The cement kiln has a high temperature, long remaining time, and can
solidify the heavy metals, dispose the solid, semi-solid or liquid wastes. To dispose the wastes in
cement kiln will not cause the new emissions. In addition, it is cheaper than building the new
incinerator plants. So utilizing the cement kiln is good way to dispose wastes in environment and
economy. Now China has more than 600 NSP cement kilns. If each kiln can dispose 100 000 tons
wastes, China cement industry would dispose about 60 million tons wastes per year. |
