Effects of decreased release of B O D / C O D and T S S on wood use

Efforts to reduce discharges of biochemical oxygen demand (BOD), chemical oxygen demand (COD) and total suspended solids (TSS) are unlikely to have significant impacts on land and wood use. These parameters are relatively insensitive to reductions in discharges to water; however, advances in wood delignification may increase pulp yield to an extent that wood requirements may decrease (or production increase with no change in wood requirements).
