Kawasaki Heavy Industries, Ltd. announced that Anhui Conch Kawasaki Engineering Co., Ltd. (ACK), a joint venture between Kawasaki and China's Anhui Conch Group, has received successive orders for a total of six Conch Kawasaki Kiln (CKK) Systems in the Chinese market. The CKK System is an environmentally friendly waste gasification system jointly developed by Kawasaki and the Anhui Conch Group. The six CKK Systems are slated to be delivered to China's Qingzhen City in Guizhou Province, Yangchun City in Guangdong Province, Qiyang, Shuangfeng, and Shimen Counties in Hunan Province, as well as Nanjiang County in Sichuan Province beginning in December 2014.
The first of its kind in the world, the CKK System is a lean, green revolutionary innovation combining the waste treatment and cement plant technologies that Kawasaki has refined over the years with the Anhui Conch Group's cement plant operational know-how. Designed to make refuse less polluting, less bulky, and more recyclable, the CKK system integrates cement manufacturing with waste processing by incorporating municipal refuse incinerators into existing cement plants.
The system turns refuse and sewage sludge into gas and effectively uses the thermal energy generated during the gasification process for cement production. This results in reduced use of coal and other fossil fuels as well as less CO2 emissions associated with cement production. The ashes generated as a result of refuse and sewage sludge gasification can be reused as materials for making cement. That eliminates the need for final disposal of incineration ash required with conventional refuse incinerators and makes the CKK System completely emissions-free.
The CKK System does not require any special facilities for treating dioxins and other toxic byproducts from the waste treatment process since they are detoxified during the cement firing process. It can also save the initial cost needed to construct a new incineration facility since it requires only adding a waste gasification system to an existing cement plant.
Kawasaki and ACK have jointly received orders for 12 CKK Systems in the Chinese market, including this latest order. The first CKK System (with a waste treatment capacity of 300 tons/day) is currently up and running in Anhui Province's Tongling City and the second system (with a waste treatment capacity of 200 tons/day) in Guizhou Province's Guiding County. Both are in factories run by Anhui Conch Cement Co., Ltd., the Chinese cement giant operating under the umbrella of the Anhui Conch Group.
Urban waste management is an urgent issue facing emerging economies like China and countries throughout Southeast Asia due to rapid urbanization. These markets are showing a keen interest in Kawasaki’s CKK System. Demand for the CKK System is expected to grow especially in China. Under the October 2013 guidance issued by China’s State Council more than 10% of existing cement plants must implement waste treatment facilities.
Kawasaki and the Anhui Conch Group have established three joint venture companies, including ACK, that are working to pave new inroads into emerging markets with environmentally sustainable and energy efficient business solutions. Kawasaki is leading the way toward creating a greener and more efficient industry standard that will have a lasting positive impact on the global environment.
