Project Looks To Paper Company Trees For Ethanol

Forest-product companies have gotten pretty good over the years at squeezing as much lumber, paper pulp and chemicals out of their trees as they can.

Now they're hoping to squeeze one more useful product out of the trees and the lands they're grown on -- transportation fuel.

Federal Way-based Weyerhaeuser Co. said Thursday that it has signed an agreement with petroleum giant Chevron Corp. to study commercial production of biofuels from cellulose-based sources, including trees and other crops that might be grown on Weyerhaeuser lands.
