“This completed installation demonstrates the flexible, scalable nature of Cereplast’s production technology and the ability of our operations management team to meet aggressive timelines,” said Frederic Scheer, chairman and CEO of Cereplast.  “I am pleased that we reached this important milestone ahead of schedule,” Sheer added.  System testing and commissioning over the coming weeks will ready the site for commercial bioresin production before the end of September 2008.  The installed production line has a nameplate production capacity of 50 million pounds of bioresin annually.   It is located on a 63 acre site that is sized for a rapid expansion of up to 500 million pounds per year as early as 2010.

Mark will be a tremendous asset and great fit for Cereplast as we execute on our strategic plans.”  An Indiana resident for more than 15 years, Mr. Barton assumes his responsibilities immediately.
