Viabilidade econômica do tratamento preservativo da madeira de algaroba Prosopis juliflora (Sw) D.C.) submetida ao método de substituição de seiva

Abstract

This work aimed to evaluate the economical viability of preservative treatment of Prosopis juliflora (Sw) D.C. round pieces treated with “Osmose CCB” commercial preservative applied by sap displacement method in rural property and to compare their costs with Mimosa caesalpiniifolia, Mimosa tenuiflora and Prosopis juliflora non-treated pieces costs. The treatment of Prosopis juliflora wood demonstrated to be economically viable when compared to alternatives using the Equivalent Annual Costs (EACs), for discount rates of 12; 15; and 18% and expected useful life varying from 16 to 30 years, in these situations treated Prosopis juliflora wood presented smaller EAC than Mimosa caesalpiniifolia, Mimosa tenuiflora and Prosopis juliflora non-treated woods for the analyzed situations, that justifies the employment of the Prosopis juliflora treated logs as fence posts and other similar uses.
