A utilização da Manihot esculent crantz (mandioca) na indústria de chapas de compensados de madeira e seu impacto econômico e social na construção civil

Abstract

This research had as objective to determine the social and economics advantages for plywood production in the civil construction substituting the flour of wheat for cassava scrap flour in the glue’s manufacturing used in manufacturing of plywood. It’s discuss about the anatomical structure of the wood and its properties, the industrial treatments and processes, the structure and the process of production of plywood beyond the substitution of raw material in the ureia-formoaldeído glue’s manufacturing, so the plywood used in buildings constructions has it’s benefit rise and the cost decreases by this substitution. The analysis show that in composition of raw material had a reduction of 7,3% in the cost of the glue. For the civil construction the plywood with cassava glue used in buildings constructor doesn’t represent a great reduction of costs, because the cost of a plywood in a build construction is only 0,84% to economics. The government created a program to incentive the families do agriculture so supporting the development important industries like civil construction.
