The objective of this paper was to show a comprehensive literature review about wood preservation in Brazil, since the earliest years until 2011. Brazil is rich in natural resources and wood has always occurred in abundance. With the industrial growing, there was the necessity of using wood with low natural durability but with chemical preservative treatment. Wood chemical treatment began in late XIX century, mainly to attend the big demand of sleepers to railroads. Only during the 60's, wood preservation gained market with the increase of scientific researches, elaboration of technical standards and building industrial plants for wood preservation. From this point on, few advances have been reached. In 2011, Eucalyptus and Pinus, were the main species used in wood preservation plants that adopts the vacuum-pressure process. In small production scale, diffusion process is adopted. Copper chromium arsenate (CCA) and Copper chromium borate (CCB) are the most preservatives utilised with some creosote utilisation. The treated wood production is concentrated in fence posts, poles and sleepers. As a trend, the wood preservation must reach new markets, such as building constructions, wood packages and crossarms, and also to intensify the traditional uses. Although there are a lot of researches about chemicals for wood preservation, CCA must keep by the years, once alternative products do not present the same efficacy or clear effects about human health and environment.
