- W89743053 abstract "The Aracruz Cellulose project in Brazil, which has a 400,000 t/yr kraft pulp mill is described. There is total integration from tree to port. Investment has been $600 million. Plans are based on increasing tree growth rates; one method will be enriching forest soils with ash from waste burning steam plants. Supplying raw material from a highly mechanized high yield forestry operation only 20 to 30 km from the plant will give an advantageous long-term cost structure. The project now has about 75,000 ha. About 59,000 ha are planted, and the rest are preserved in their natural state, as required by Brazilian regulations. Forest yields are calculated in terms of pulp; current production in estimated at 9 t/ha/yr when genetically superior trees are ready for harvest in 7 years. A computer model has been developed for forest soil compaction. During planting, ash and chemical fertilizer are added to the soil; trees drop 6 t/ha of leaves, which also add nutrients to the soil. A seed orchard for tropical pine will be producing seeds in 5 years. One and a half million native Brazilian trees have also been planted along with other exotic species, such as ironwood and teak." @default.
