- © 2013 IEEE.This paper applies to the redesign of a brick in which the selection of the material and the internal geometry are designed to increase sound absorption together with an improvement in structural strength. The definition of the material opportunity is given by the sawmill industry in Mexico, which produces about 2 million tons of sawdust per year, almost all wasted, and another important waste material: plastic. Each year, Mexico produces 992 000 tons of low density polyethylene. These two waste products can be used as raw materials to create wood plastic composite.
