A medical waste combustion facility is required to undergo a waste composition study every five years as a requirement of its air emission permit under MN Rule 7007.0501, Subpart 2. The study requirements include performing a fractional analysis, proximate analysis, ultimate analysis, and heat value evaluation of the medical waste processed by the facility.

Pinnacle Engineering has been retained on two occasions to conduct the study which has included the following services:

  • Met with client to identify waste composition study project aspects and logistics.
  • Developed a site safety plan.
  • Submitted a waste sorting Protocol to MPCA prior to analysis.
  • Sorted waste onsite according to established methods into predetermined categories and weighed for fractional analysis.
  • Prepared samples for submission to laboratory for further analysis (proximate, ultimate, and heat value testing).
  • Prepared summary report detailing the field and laboratory work with statistical analysis of the results. 
  • Submitted final report to MPCA.

Working with and processing medical waste can be hazardous due to potential exposures to biological pathogens, sharps, and other medical related wastes.  Much of the waste encountered in this project was autoclaved to minimize some inherent risks involved with potential exposure, reducing but not eliminating all potential risks associated with conducting the study.  Pinnacle established and adhered to a specific site safety plan for the study’s required field work, thereby ensuring a safe work environment for Pinnacle employees while satisfying the study requirements.

 Pinnacle provided efficient and knowledgeable skilled personnel to properly conduct the waste composition study, as well as top end engineering review of the final report, satisfying client and regulatory requirements.
