Feb 15, 2013. /Lesprom Network/. Tembec is announcing the departure of Executive Vice President, Specialty Cellulose and Chemical Group, Yvon Pelletier and appoints Christian Ribeyrolle as Executive Vice President, Specialty Cellulose. Mr. Pelletier will leave Tembec on February 22, 2013, as the company said in a press release received by Lesprom Network. Mr. Ribeyrolle has been with Tembec for ten years. He joined Tembec in 2003 as Manager of the pulp mill in Tartas, France, with an annual production capacity of 150,000 metric tons. In 2008, he was promoted to the position of Director of Sales, Specialty Cellulose, and in 2009, he became Senior Vice President, Specialty Cellulose, and President, Tembec SAS, France.

He has led the transformation of the Tartas mill, making it a very profitable operation with a reputation that is recognized internationally in the specialty cellulose market. Christian's deep expertise, his more than 25 years experience in the industry, and his skills as a manager, have served to position Tembec among the global leaders in the specialty cellulose market. We are very pleased to count on his contribution to our executive team," said James Lopez , President and CEO of Tembec. "Christian has been a tremendous asset in the development of the specialty cellulose component of Tembec's business portfolio," he added. "I would like to take this opportunity to thank Yvon Pelletier for his 32 years of service and recognize his commitment to the Company during his tenure with Tembec. We wish Yvon well," Mr. Lopez stated. Tembec is a manufacturer of forest products - lumber, pulp, paper and specialty cellulose - and a global leader in sustainable forest management practices.
