Shandong Shanxian Zhongcheng Paper Co., Ltd.

Shandong Shanxian Zhongcheng Paper Co., Ltd is located in the east of Beihuan Road, Shanxian. Covering an area of 500 Mu, jointly invested and founded by Shandong Nanbao Xiangrui Hi-tech Investment Co., Ltd and Mr. Cheng Xiangwu, the inventor of DMC (Digesting with Material Cleanly, Patent No.: ZL200410096066.1, ICM: D21C3/20) clean pulping technology. This is an energy saving and environmental protection tech, reached using water but not draining water, no toxicity, no smell, no bubbles were generated, ensures free from contamination, it is the first enterprise of pollution-free pulping and papermaking in the whole nation. Taking the straw, wheat straw, cotton stalk and other crops stalk as the raw materials, is one of projects of deep processing of agriculture by-products. Now we have declared from National Development and Reform Commission and got the approval as national demonstration base for large-scale production of clean pulping.

The principle of DMC technology is to utilize special efficiency of the catalyst, making the plant fibers achieved the purpose of clean pulping by deflaking, catalysis, refining, bleaching, water treatment by stages and other processes. Its characteristics are: No streaming, no black liquor, no waste water, etc contaminations. Achieved using water but not draining(zero discharging), completely realized cleanliness, thoroughly solved the environmental problems in the process of papermaking and pulping processes.

Simultaneously, The DMC technology has many outstanding advantages: High technology content, wide application range, high ratio of output to input, short construction period, small floor area, full automation, closed cycle, no noise, no peculiar smell, high purifying rate, no need of maintenance, low running cost. In addition, the treated waste water can be recycled many times and needn`t to drain ourside, thus the secondary pollution can be avoided thoroughly. The water quality measures up to the national first class standard. This invention successfully inverted a high pollution industry to be an environmental friendly industry.

Now we are glad to export this DMC technology. If you are interested in it or for detailed information, Pls do not hesitate to contact me.
