Medical waste: a minimal hazard
1Department of Biostatistics, School of Basic Health Sciences, Medical College of Virginia/Virginia Commonwealth University, Richmond.
Abstract:
Medical waste is a subset of municipal waste, and regulated medical waste comprises less than 1% of the total municipal waste volume in the United States. As part of the overall waste stream, medical waste does contribute in a relative way to the aesthetic damage of the environment. Likewise, some small portion of the total release of hazardous chemicals and radioactive materials is derived from medical wastes. These comments can be made about any generated waste, regulated or unregulated. Healthcare professionals, including infection control personnel, microbiologists, public health officials, and others, have unsuccessfully argued that there is no evidence that past methods of treatment and disposal of regulated medical waste constitute any public health hazard. Historically, discovery of environmental contamination by toxic chemical disposal has followed assurances that the material was being disposed of in a safe manner. Therefore, a cynical public and its elected officials have demanded proof that the treatment and disposal of medical waste (i.e., infectious waste) do not constitute a public health hazard. Existent studies on municipal waste provide that proof. In order to argue that the results of these municipal waste studies are demonstrative of the minimal potential infectious environmental impact and lack of public health hazard associated with medical waste, we must accept the following: that the pathogens are the same whether they come from the hospital or the community, and that the municipal waste studied contained waste materials we now define as regulated medical waste.(ABSTRACT TRUNCATED AT 250 WORDS)
Insights
Medical waste is a small fraction of municipal waste. Studies on municipal waste suggest that regulated medical waste disposal poses minimal public health risks.
Area of Science:
- Environmental Science
- Public Health
- Waste Management
Background:
- Regulated medical waste is a minor component of total municipal waste.
- Concerns exist regarding the environmental and public health impact of medical waste disposal.
- Historical incidents of environmental contamination from waste disposal necessitate proof of safety.
Purpose of the Study:
- To evaluate the public health risks associated with medical waste treatment and disposal.
- To determine if existing municipal waste studies can demonstrate the safety of medical waste management.
- To address public and official demands for proof of safety in medical waste disposal.
Main Methods:
- Analysis of existing studies on municipal waste composition and impact.
- Assumption that pathogens in medical waste are comparable to community pathogens.
- Assumption that studied municipal waste includes regulated medical waste components.
Main Results:
- Medical waste constitutes less than 1% of US municipal waste volume.
- Medical waste contributes minimally to aesthetic environmental damage.
- A small fraction of hazardous chemicals and radioactive materials originate from medical waste.
Conclusions:
- Existing municipal waste studies suggest minimal infectious environmental impact from medical waste.
- Proof of safety for medical waste disposal can be inferred from municipal waste studies.
- The public health hazard associated with regulated medical waste is likely minimal.
