Abstract
A method for transforming a waste product containing or completely formed of amiantus comprising subjecting the waste product to several working phases and adding of components such as calcined alumina, clay and material having a given porosity so to produce a final manufactured product free of any amiantus.

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.
A method of transforming a waste product including amiantus or amiantus together with other undesired products or materials, all forming components of the waste product to be transformed comprising:
- a grinding phase in which the waste product which includes amiantus alone or other waste products together with amiantus is reduced to a dimension no greater than 0.063 millimeters;
- a dosing phase in which different components are weighed and having a given porosity including either wood flour or hazel-shell flour;
- a mixing phase wherein the components are placed into a counter-rotating mixer and nebulized water is added in a percentage of from 20 to 35% of the total of dry weight of the components;
- an extrusion phase for producing a plastic mass by forcing through a die chaser to produce a semi-manufactured product;
- a drying phase for drying the semi-manufactured product to a temperature lower than or not to exceed 100° C.;
- a burning phase where the manufactures of the waste products are passed inside furnaces to reach a temperature up to 1250° C.;
- an inspection phase in which the amiantus or other waste products combined with amiantus is no longer present inside the resultant manufactured product such that the waste product is completely eliminated from the manufactured product;
- and a packaging/storing phase in which the resultant manufactured waste product which is free of amiantus or amiantus and waste is packaged and stored to complete the working cycle.
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
- a heating phase which includes the following steps:
- for the first two hours the material is heated to a temperature of 350° C.;
- for the next two hours and up to the fourth hour the material is heated to a temperature of 550° C.;
- for the next two hours and up to the sixth hour, the material is heated to a temperature of 800° C.;
- for the next three hours heating until the temperature of 1050° C. is reached;
- and for another four hours heating until a temperature of 1200° C. is reached.
