The largest Chinese hydrosulfite
1994 - Our plant reached the capacity of 18,000 MT/year in
the first year of operation and made Zhongcheng the largest hydrosulfite
plant in China. Using advanced technology, we managed to produce
the chemical with only 1/3 of the energy consumption required by
The largest sodium hydrosulfite Plant in
1994-1998 - By 1998, our Guangdong plant became the largest
sodium hydrosulfite plant in the world - our capacity reached 90,000
Domestic market leader
1998 - Zhongcheng acquired 70% interest in the second largest
hydrosulfite plant (30,000 MT/year capacity) in China located in
Hunan, South China. As a result of this acquisition, we captured
80% of the market share in the domestic hydrosulfite industry.
1999 - Zhongcheng targeted to strengthen its role in the
global hydrosulfite market.
- We decided to further increase our capacity by constructing
a new hydrosulfite facility in our Guangdong plant
- We paid significant attention to safety and environmental issues
and invested heavily to build waste material disposal systems.
We also started producing a series of recycled products, such
as sodium thiosulfate, CO2, and dry ice.
Our export exceeded 45,000 MT in this year.
1/3 of global capacity
2000 - Zhongcheng's hydrosulfite production yield accounted
for more than one third of the global hydrosulfite capacity after
our new hydrosulfite facility began production. Our total capacity
reached 190,000 MT/year in this year.
