Michigan Compiled Laws, Chapter 333. Health § 333.13821

(a) Sharps that are not ground or incinerated as described in section 13811(d)  1 shall be contained for disposal in individual leakproof, rigid, puncture-resistant containers that are secured to preclude loss of the contents. In addition, a container used to store or transport a number of individual sharps containers shall be leakproof. These containers shall be conspicuously labeled with the word “sharps”. Sharps that are contained pursuant to this subdivision may be disposed of as solid waste pursuant to part 115 (solid waste management) of the natural resources and environmental protection act, Act No. 451 of the Public Acts of 1994, being sections 324.11501 to 324.11549 of the Michigan Compiled Laws. However, sharps shall not be compacted or handled during transport in a manner that will result in breakage of a sharps container.

(b) Medical waste other than sharps shall be contained in bags other than body pouches or other containers that are impervious to moisture and have a strength sufficient to resist ripping, tearing, breaking, or bursting under normal conditions of usage or handling. The bags or containers shall be secured so as to prevent leakage during storage, handling, or transport.
