Abstract
The present invention provides a manufactured aggregate material that converts waste materials and/or recyclable materials into construction material. By mixing waste materials with an acid solution and a metal oxide solution, any harmful contaminates in the waste materials are encapsulated and rendered into hard pellets that are suitable for use in conglomerates or composites such as concrete. The manufactured aggregate material may be adjusted for moisture content, density, heat capacity, and other parameters.
Claims24
A method of preparing aggregate material, said method comprising:
- providing a waste material in granular form;
- mixing the waste material with an acid to obtain a first resultant product;
- mixing the first resultant product with a metal oxide to obtain a second resultant product;
- and
- pelletizing the second resultant product to obtain the aggregate material.
A method of preparing aggregate material, said method comprising:
- providing at least one hopper for containing a waste material therein;
- dispensing the waste material into a first mixer;
- dispensing phosphoric acid from a first tank into the first mixer;
- mixing the waste material and the phosphoric acid in the first mixer to obtain a first product;
- dispensing the first product into a second mixer;
- dispensing magnesium oxide from a second tank into the second mixer;
- and
- mixing the first product and the magnesium oxide in the second mixer to obtain a second product;
- dispensing the second product into an agglomerator;
- and
- pelletizing the second product in the agglomerator to obtain the aggregate material.
A manufacturing facility for manufacturing aggregate material, said facility comprising:
- a hopper for storing and dispensing a waste material;
- an acid tank for storing and dispensing an acid;
- a first mixer for receiving and mixing the waste material and the acid to produce a first mixture, said first mixer adapted to dispense the first product;
- a metal oxide tank for storing and dispensing a metal oxide solution;
- a second mixer for receiving and mixing the first mixture and the metal oxide solution to produce a second product upon reaction of the acid and the metal oxide;
- and
- an agglomerator adapted to pelletize the second product into pellets;
- wherein the first product at least partially results from a first chemical reaction in said first mixer, and the second product at least partially results from a second chemical reaction in said second mixer.
