Abstract

Methods of reclaiming plastic from plastic medical waste containers containing medical waste and manufacturing recycled medical devices are described. Recycled medical devices made from plastic medical waste containers containing medical waste are also described.

Claims (12)

1. A method of making a recycled medical device comprising forming a recycled medical device from a recycled plastic resin produced by shredding and sterilizing in a single pressurized tank a mixture of plastic medical waste containers containing medical waste soaked in superheated water and steam and circulated through a cutter.

2. The method of claim 1 , wherein the plastic resin is separated from the metal and/or glass by float-sink a technique.

3. The method of claim 1 , wherein the plastic resin comprises only polypropylene and polyethylene.

4. The method of claim 1 , further comprising formulating the plastic resin prior to forming the recycled medical device.

5. The method of claim 1 , wherein the used plastic medical waste containers comprise polypropylene and polyethylene, and greater than about 60% of the polypropylene and polyethylene is recovered and incorporated into the recycled medical device.

6. The method of claim 1 , wherein the plastic medical waste containers are obtained from a medical facility.

7. The method of claim 1 , wherein the recycled medical device is selected from the group consisting of a waste container, a non-fluid path medical device and a fluid path medical device.

8. The method of claim 1 , wherein the contents of the plastic medical waste containers comprises molded plastic, glass components and metal components.

9. The method of claim 1 , wherein the medical waste contained in the plastic medical waste containers comprises infectious waste.

10. The method of claim 1 , wherein the shredded waste is heated to a temperature of about 272° F.

11. The method of claim 10 , wherein the shredded waste is held at about 272° F for about 6 minutes.

12. The method of claim 1 , wherein the shredded waste does not require a separate washing process.
