Abstract:
1. Transformation method of waste products containing or including all amiantus, for rendering thereof innocuous and salubrious and for use in manufacture of products for construction material comprising the steps of: adding to the waste product components selected from the group consisting of calcined alumina, clay and materials having a porosity substantially equivalent to wood flour or hazel-shell flour at least once; and comprises working steps which includes the following working phases: a grinding phase wherein the waste products are reduced to a dimension no greater than 0.063 millimeters to produce micronized amiantus; a dosing phase in which the different components including the micronized amiantus are dosed and weighed; a mixing phase wherein the components are placed inside a mixer and adding nebulized water in a range of from 20 to 35% of the total of dry weight; an extrusion phase for realizing a plastic mass; a dimensioning phase to obtain a semi-manufactured product of desired dimensions for use in construction of buildings or structures; a drying phase for drying where the semi-manufactured product is dried to a temperature below 100° C.; a burning phase in which the manufactured products are passed inside of a furnace capable of reaching a temperature of 1250° C. to subject the semi-manufactured product to a temperature up to 1250° C.; and an inspection phase and a final last phase of packaging/storing wherein the manufactured product, is free of amiantus, is packaged and stored for completion of the working cycle such that the manufactured product is usable in building structures.
