  • However, China’s industry is dependent on non-wood fibers (largely agricultural residues) at a 3:1 ratio over wood fiber. This suggests a concentration of many smaller operations. In fact, China’s rapid agricultural growth since 1978 provided fiber for eight-fold growth in the production of smaller papermills between 1984 and 1992 (CTAPI (1993)). The smaller mills have been rapid innovators, but they remain especially environmentally intrusive. They are dependent on pollution control technologies that are not as effective for non-wood fibers.
