Like other healthcare fields, the dental industry generates a significant amount of waste that can have considerable environmental and public health implications.
Dental practices produce several types of waste, from potentially infectious and hazardous materials to general (or day-to-day) waste products you’d find in other offices and clinics. Consequently, it’s critical for modern dental practitioners to address these waste materials in a responsible and compliant manner.
This article will explore six main sources of waste in dental practices and provide an analysis of best practices for handling each type.
The Main Sources of Dental Waste
Dental scrap: Dental scrap, such as extracted crowns, bridges and other precious metals, constitutes a significant portion of dental waste. Luckily, dental practices can partner with specialized dental refining services that offer recycling specifically tailored to this need.
These refining companies provide secure and environmentally friendly processes to extract precious metals, such as gold, silver, platinum and palladium, from dental materials while adhering to strict regulatory and environmental standards. Leading companies offer transparent tracking of the refining process, competitive payouts, and environmentally conscious practices.
Dental Amalgam: Dental amalgam contains mercury, which poses significant environmental concerns. Proper management is thus crucial to avoid contamination. To address this, dentists can implement best management practices that include the use of amalgam separators which are designed to remove waste amalgam from wastewater before discharge into the sewer. Moreover, recycling dental amalgam and using alternatives – such as composite resins, can significantly reduce the environmental impact.
Hazardous Chemical Waste: This category includes various chemicals used in dental setting, such as those used in X-ray processing, adhesives and lead foil. To handle these hazardous chemical wastes, dental practices should ensure proper labeling and segregation of these materials. The substitution of hazardous chemicals (where possible) and adherence to best management practices for their disposal can mitigate most negative environmental effects.
Biomedical Waste: Biomedical waste refers to materials capable of causing disease or those suspected of harbouring pathogenic organisms. Proper segregation, waste storage in appropriate containers and safe disposal methods are crucial to prevent cross-infections, needle sticks and potential environmental hazards. The safe management of blood-soaked materials and sharps is particularly important to prevent the spread of disease and ensure safety for everyone involved.
General Office Waste: Modern practices can lessen general office waste by opting for products with minimal packaging, using reusable items where possible, and choosing materials made from recycled or partly recycled sources. Moreover, energy-efficient lighting & temperature regulation can help minimize office energy use – reducing overall waste generation and the related environmental impact.
Unused Film and Lead Foil: Acknowledging the environmental impact of these waste materials is crucial. Implementing responsible waste management practices, such as returning unused film for recycling and proper disposal of lead foil can significantly reduce the environmental footprint of dental practices.
Advanced Technologies for Dental Waste Management
Technology has significantly influenced the responsible disposal of dental waste.
Amalgam separators, for instance, can remove up to 99% of mercury from wastewater, thus preventing its release into the environment. Chair-side traps and secondary filters have also proved to be effective in removing amalgam particles from dental wastewater, significantly limiting their environmental release. Also, digital radiography helps in removing the use of X-ray chemicals.
