Method of producing building materials from recycled items

摘要

Various building materials constructed from different recycled components are provided. Such materials include boards, bricks, and the like, and exhibit differing levels of tensile strength, heat resistance, and other physical and chemical properties. The capability of introducing varied collected items, including paper, paperboard, clothing fibers, wood chips and strips, raffia bags, used engine oil, etc., and produce a resilient and dimensionally stable building material is presented herein. Replacement of timber and concrete is permitted with such a new material based upon renewable resources. The method of production and use of such materials is encompassed herein as well.

主权项

1. A method of producing solid load-bearing article provided in a three-dimensional geometric shape including the steps of:
1) producing an initial fiber/paper-based component comprising the steps of
a) providing materials consisting essentially of shredded fiber, shredded paper, shredded paperboard materials, and any combination thereof;b) mixing said materials to generate a pulp formulation, andc) mixing the pulp formulation with calcium hydroxide to form the fiber/paper-based component; 2) producing an initial hydrophobic wood-based component comprising the steps of
a) providing ground wood materials exhibiting a size from about 0.5 to 1 inch in length andb) coating said wood materials with used engine and/or cooking oil, thereby producing the wood-based component; 3) producing a polymer-based fiber component comprising the steps of
a) providing raffia polypropylene bags, andb) shredding the bags through a screen device to produce an average length of from 1 to 3 inches, thereby providing the polymer-based fiber component; 4) mixing said paper-based component, wood-based component, and polymer-based component together with pozzolan, Portland Cement, and water within a device to provide a homogeneous liquefied composition; 5) introducing said liquefied composition within a mold for at least 12 hours; 6) removing the resultant board from the mold and curing said board at a temperature of at least 200° C.; and 7) allowing said resultant cured board to cool to room temperature.
