China Makes Breakthrough in Secondary Pollution of Reclaimed Rubber

A reclaimed rubber production line with annual capacity of 5,000 tonnes has been settled in Hengshui, Hebei province, under joint cooperation between Beijing University of Chemical Technology and Hengshui Huarui Rubber Co.

It marks China's production of reclaimed rubber realized "near-zero emission" and the secondary pollution concern of the reclaimed rubber sector is to be solved.

Hengshui is a rubber industrial base in China as well as a primary market for rubber and chemical materials, particularly for engineering rubber, which Hengshui takes up over 60% of the country's total market share.

Zhang Liqun, a professor at BUCT, said the two sides reached a strategic agreement to establish a specific group to breakthrough the second pollution problem of reclaimed rubber and realized "near-zero emission" in the process from rubber powder to preparation of reclaimed rubber.

The production line settles in Hengshui is the physical practice of the new technology.

With regard to pollution generated from high-temperature desulfurization, a water-free technical formula has been adopted by the production line for desulfurization, and the progress for heating up and cooling down rubber powder is completed under an airtight condition, thereby solve the pollution problem at the source.
