The pulp and paper industry is one of the most global in nature. Trees are most productively grown in scattered pockets of forest, but demand is dispersed by a different set of factors. Decisions made in Singapore, Memphis and Auckland have a significant effect on markets elsewhere. Collectively the data includes 46 per cent of the world's population, 42 per cent of GDP and 51 per cent of paper and board demand. As developing country populations obtain more discretionary income, it is used for buying food and goods in packages, tissue and towel products, and reading materials. The contribution of the developing economy in towards paper and board demand, and the specific grade growth, leads to important implications for virgin pulp fiber and demand and from forests. Outside North America, packaging board, especially corrugated containers from linerboards, are produced with greater than 90 per cent recycled fiber from recovered paper.
