Kellogg Company announced that it is expanding its W.K. Kellogg Institute for Food and Nutrition Research (WKKI) located in Battle Creek, Mich., to continue to meet business needs and to achieve continued growth. The 157,000-square- foot pilot plant and office space addition will expand Kellogg Company's existing global center for research and innovation activities. The $40 million expansion and $14 million investment in pilot plant equipment (over the next 10 years) falls within Kellogg Company's previously reported capital expenditure guidance.  Assuming approval of the APRZ and approvals by the Michigan Department of Environmental Quality, construction will begin in the second quarter of 2008. The expansion is expected to be operational in the third quarter of 2009.
