Abstract

A process for making a solid component out of recycled paint sludge is provided. The process can include providing a paint sludge and providing a second material. Thereafter, the paint sludge and the second material are mixed to produce a paint sludge-second material mixture. The paint sludge-second material mixture is processed in order to produce a polymer containing precursor. The processing can include granulating or densifying the paint sludge-second material mixture. After the precursor has been produced, it can be placed within a molding machine and a solid component is molded. The molding machine can be an injection molding machine, an extrusion molding machine or a blow molding machine.

Claims

1. A process for making a solid component out of recycled paint sludge, the process comprising:

providing paint sludge;

providing a second material;

mixing the paint sludge with the second material to produce a paint sludge-second material mixture;

processing the paint sludge-second material mixture, the processing selected from the group consisting of granulating and densifying, the processing producing a precursor made from recycled paint sludge;

placing the precursor in a molding machine, the molding machine selected from the group consisting of an injection molding machine, an extrusion molding machine and a blow molding machine; and

molding a solid component from the precursor.

2. The process of claim 1, wherein the paint sludge is from an oil-based paint.

3. The process of claim 1, wherein the paint sludge is from a water-based paint.

4. The process of claim 1, wherein the second material is a virgin material.

5. The process of claim 4, wherein the second material is virgin polymer.

6. The process of claim 1, wherein the second material is a recycled material.

7. The process of claim 6, wherein the second material is recycled filter media.

8. The process of claim 1, wherein the paint sludge-second material mixture has a paint sludge content of between 1 to 99 weight percent.

9. The process of claim 8, wherein the paint sludge content is between 20 to 80 weight percent.

10. The process of claim 9, wherein the paint sludge content is between 30 to 70 weight percent.

11. The process of claim 1, wherein the solid component has a density of greater than 80 percent.

12. The process of claim 11, wherein the solid component has a density of greater than 85 percent.

13. The process of claim 1, wherein the paint sludge is obtained from paint used to paint a motor vehicle.

14. The process of claim 1, wherein the paint sludge is obtained from paint used to paint a motor vehicle on an automotive assembly line.

15. A solid component made from recycled paint sludge, said component comprising:

a density of greater than 80 percent;

a recycled paint sludge content greater than 20 weight percent; and

a second material.

16. The solid component of claim 15, wherein said density is greater than 85 percent.

17. The solid component of claim 15, wherein said paint sludge is greater than 30 weight percent.

18. The solid component of claim 15, wherein said paint sludge is greater than 40 weight percent.

19. The solid component of claim 15, further comprising a third material.

20. The solid component of claim 19, further comprising a fourth material.
