Jakarta, Nov. 27 (Bloomberg) - Asia Pulp & Paper Co., Asia's largest pulp and paper maker outside of Japan, is facing a wood fiber shortage that could raise operating costs and erode future profits, according to independent research. The research sponsored by the Indonesia-based Center for International Forestry Research and the World Wide Fund for Nature Macroeconomics Program Office - finds that yields from the company's timber plantations will meet only half the wood needed for its main mill at PT Indah Kiat Pulp & Paper unit to run at full capacity, at best.
