Nearly 40% of the trees cut in North America are used for paper production. An alternative to wood pulp is plant fiber—either agricultural residue from crops or fibers from plants grown for tree-free paper. The most common are kenaf, hemp, flax, bamboo and cotton. Plant fibers tend to be more durable. Containing less lignin than trees, kenaf requires fewer chemicals, less energy to process, is naturally acid free and can be recycled. One-hundred percent cotton paper has low acidity and is frequently used for archival purposes. |
