Abstract
A synthetic cover for waste piles may be formed from a mixture of liquid, binder, cellulose fibers and plastic fibers. These constituents may be mixed and applied to cover a waste pile. The cover will harden to minimize odor and affinity to birds, flies and other insects. The liquid may include water; the binder may include cement kiln dust with or without bentonite, or portland cement with flyash or stone dust. The cellulose fibers may comprise shredded paper or wood.
Claims34
A mixture for covering waste piles comprising the following constituents:
- up to approximately forty five percent, by weight, liquid;
- a plurality, by weight, of a binder;
- a minority portion of cellulose fibers and plastic fibers sufficient to prevent erosion;
- and
- wherein a mixture of the constituents forms a thick viscid slurry capable of being sprayed in a uniform layer of approximately a quarter of an inch to form a daily or interim cover.
A mixture for covering waste piles comprising the following constituents:
- approximately thirty eight percent to forty five percent, by weight, liquid;
- approximately fifty four percent of sixty percent, by weight, binder;
- approximately one-half percent to two percent, by weight, cellulose fibers;
- and
- up to approximately one-tenth of a percent, by weight, plastic fibers;
- and
- wherein a mixture of the constituents forms a thick viscid slurry capable of being sprayed in a uniform layer of approximately a quarter of an inch to form a daily or interim cover.
A mixture for covering waste piles comprising:
- about thirty nine to forty five percent, by weight, water;
- about fifty five to sixty percent, by weight, cement kiln dust;
- about one-half to two percent, by weight, shredded paper;
- up to about one-tenth percent, by weight, polyethylene terephthalate fibers;
- and
- wherein the constituents form a mixture of a thick viscid slurry capable of being sprayed in a uniform layer of approximately a quarter of an inch to form a daily or interim cover.
A method of making cover for waste piles comprising:
- mixing cellulose fibers and plastic fibers sufficient to prevent erosion with a liquid to form a pre-mixture;
- and
- mixing a binder reagent to form a final mixture, wherein the final mixture forms a thick viscid slurry capable of being sprayed in a uniform layer of approximately a quarter of an inch to form a daily or interim cover.
A method of covering waste piles comprising:
- mixing a binder, cellulose fibers and plastic fibers sufficient to prevent erosion, and liquid together to form a mixture of a thick viscid slurry capable of being sprayed in a uniform layer of approximately a quarter of an inch to form a daily or interim cover;
- coating a waste pile with the mixture;
- and
- allowing the coating of mixture to harden as a cover on the waste pile.
