PTT program.

On May 5, 2013, a ground-breaking ceremony of a 20,000t/a biological PDO and 50,000t/a
PTT program was held by Shenghong Group Co., Ltd. (Shenghong Group). This program is
owned by Suzhou Suzhen Biological Engineer Co., Ltd., a subsidiary of Shenghong Group.
The launch of this program enables Shenghong Group to have a whole production chain from
biological raw material, PTT polyester to PTT spinning and fabric printing & dyeing, according
to CCM’s latest issue of Biomaterials China News 1305.
The newly-launched biological PDO and PTT program is just the first phase of Shenghong
Group's whole PDO and PTT program, and is planned to be put into production at the end of
2013, while the second phase with capacities of 40,000t/a PDO and 100,000t/a PTT is
expected to enter operation in 2015. By cooperating with Tsinghua University, PDO will be
produced by biological method, fermented from glycerol—a by-product of biodiesel, which is
different from the raw material of general biological PDO, such as DuPont's PDO.
This program will be perfection and expansion of Shenghong Group’s current PTT business.
PTT fiber is famous as a kind of "memory fiber", but the supply shortage of its core raw
material—PDO hasseriously restricted the development of the PTT industry. In June 2011,
Shenghong Group’s first domestic PTT production line with a capacity of 30,000t/a entered
trial production, allowing the company to become the third one who mastered the core
technology of PTT in the world, only after DuPont and Shell. However, the company does not
have its own PDO production line, and most of PDO it needed is bought from Shell. According
to Mr. Bian, the company’s chief engineer, the outsourced BDO cannot meet the company's
production needs. Another industry insider, Mr. Han, also revealed that though Shenghong
Group has a large PTT production capacity, its PTT output is far smaller than its capacity due
to the supply shortage of PDO.
In the future, after the company’s new program is finished, the raw material bottleneck will be
solved, and the newly-constructed PTT production line and the company’s integrated
production chain will greatly help the company to win more market share.
Along with the technology innovation and the great development of the biodiesel industry,
more domestic enterprises will enter the PDO industry, and China may become one of the
largest PDO producers in the future.
In addition to Shenghong Group, Zhangjiagang Glory Biomaterial Co., Ltd. (Glory Biomaterial)
also launched a biological PDO program, and the first phase with a capacity of 20,000t/a PDO

2. has entered pilot production in Jan. 2013. Similar to Shenghong Group, Glory Biomaterial also
produced PDO from glycerol by cooperating with another university—East China University of
Science and Technology.
