Abstract

The present disclosure relates to an eco-friendly sand-made paper and a method of manufacturing thereof. In an aspect, the proposed sand-made paper can be obtained/manufactured through a method comprising the steps of treating a polymer with a solvent so as to obtain solvent treated polymer; and processing said solvent treated polymer with fine powdered sand optionally with a binder to yield said sand-made paper.

Claims

1. A method of making sand-made paper, the method comprising the steps of:

treating a polymer with a solvent so as to obtain solvent treated polymer;

processing said solvent treated polymer with fine powder like sand optionally with a binder to yield said sand-made paper.

2. The method of claim 1, wherein the method further comprises the step of rolling said sand-made paper to provide one or more sand-made paper based sheet.

3. The method of claim 1, wherein said fine powder like sand has a mean particle size less than 32 microns.

4. The method of claim 1, wherein said fine powder like sand is obtained through sieving of naturally occurring sand.

5. The method of claim 4, wherein said naturally occurring sand is at least one of brown sand, white sand, grey sand and red sand.

6. The method of claim 1, wherein said polymer is in a form selected from at least one of powdered polymer, processed polymer, and polymer pellets.

7. The method of claim 1, wherein said polymer is selected from at least one of polyethylene, and high density polyethylene (HDPE).

8. The method of claim 1, wherein said solvent is selected from at least one of toluene and acetone.

9. The method of claim 1, wherein said solvent is toluene, and said polymer is powdered HDPE.

10. The method of claim 1, wherein said fine powder like sand and said solvent treated polymer are processed in a ratio ranging from 80:

20 to 30;

70.

11. The method of claim 1, wherein said fine powder like sand and said solvent treated polymer are processed in a ratio of around 50:

50.

12. The method of claim 1, wherein said binder is selected from at least one of polyvinyl alcohol, polyether sulfone, sorbitan monooleate, and silica.

13. The method of claim 1, wherein said method further comprises the step of pre-processing said fine powder like sand by bleaching, prior to carrying out the step of processing.

14. A sand-made paper comprising:

a fine powder like sand; and

a solvent treated polymer obtained by treating a polymer with a solvent, wherein said solvent treated polymer is processed with said fine powder like sand optionally with a binder to yield said sand-made paper,

wherein said solvent is toluene and said polymer is selected from at least one of polyethylene and high density polyethylene (HDPE).

15. The sand-made paper of claim 14, wherein the sand-made paper is rolled to provide one or more sand-made paper sheet.

16. The sand-made paper of claim 14, wherein the fine powder like sand has a mean particle size less than 32 microns.

17. The sand-made paper of claim 14, wherein said fine powder like sand is obtained through sieving of naturally occurring sand.

18. The sand-made paper of claim 17, wherein said naturally occurring sand is at least one of brown sand, white sand, grey sand and red sand.

19. The sand-made paper of claim 14, wherein said polymer is in a form selected from at least one of the powdered polymer, processed polymer, and polymer pellets.

20. The sand-made paper of claim 14, wherein said solvent is selected from at least one of the toluene and acetone.

21. The sand-made paper of claim 14, wherein said polymer is powdered HDPE.

22. The sand-made paper of claim 14, wherein said fine powdered sand and said solvent treated polymer are processed in a ratio ranging from 80:

20 to 30;

70.

23. The sand-made paper of claim 14, wherein said fine powdered sand and said solvent treated polymer are processed in a ratio of around 50:

50.

24. The sand-made paper of claim 14, wherein said binder is selected from at least one of polyvinyl alcohol, polyethersulfone, sorbitan monooleate, and silica.
