I got this press release the other day and thought I would pass it along without comment. Take a look and then leave comments. I'd love to hear what you think about this:
According to the Authority on Green Dentistry, the Gulf of Mexico Disaster is Another Reason Why the Dental Industry Needs to Curb the Use of Petroleum-Based Plastics
Berkeley, CA (July 29, 2010) – According to the Eco-Dentistry Association™ (EDA), an international association promoting environmentally sound practices in dentistry, the widespread use of disposable dental supplies, such as chair covers and sterilization pouches, helps perpetuate the country’s dependency on petroleum because single-use plastics are made
from oil.
According to Susan Beck, Director of the Eco-Dentistry Association, “The oil catastrophe in the Gulf of Mexico is causing many Americans to consider the true risk and cost of pollution-based energy. The dental industry can show leadership by helping curtail our nation’s dependence on fossil fuels.”
It’s not just about turning off the lights. Many dental practitioners don’t think about the “embodied energy” hiding in everyday dental supplies. “Embodied energy represents all the energy used in the life cycle of an item, from raw material to its final resting place,” explains Beck.
“The biggest offenders for hidden embodied energy in the typical dental office are disposables. Because disposables are by definition single-use, the return on the energy investment for the product is extremely low. Tremendous energy resources are used to extract raw materials, which are generally petroleum-based, to create a product that is manufactured, packaged, shipped, stored, and then shipped again to a dental practice to be used once. Additional energy
is consumed to transport that product to a landfill, where it may sit for thousands of years,” states Beck.
The EDA recommends choosing reusable dental supplies wherever possible. For example,
a single plastic sterilization pouch represents nearly 60 watts of embodied energy (www.wattzon.org), which is the same amount of energy as leaving a 60-watt incandescent lightbulb turned on for 5 hours!
An average dental office can use as many as 55 plastic sterilization bags per day,1 which equates to leaving a 60-watt incandescent lightbulb on for eleven and a half days. By the end of the year, the practice would have utilized enough energy, in plastic pouches alone, to fuel a 60-watt incandescent bulb non-stop for six years and three months. Conversely, a dental office would have to use a cloth pouch over 4,800 times before it would have used the energy represented by one plastic pouch.
Even without adding in the cost of embodied energy to the dental supplies invoice, many practitioners are surprised to find that disposables actually increase supply costs. For instance, a large disposable autoclave pouch costs about 20 cents per use, while a reusable pouch costs about half as much per use. Disposable items for infection control and sterilization can cost a dental practice as much as $2,337 per year more than an office making the greener choice of reusable items.2
What’s more, choosing disposable paper or plastic rinse and swish cups instead of reusable substitutes can cost a practice $178 or more per year, even when the cost of a dishwasher is included in the assessment.2 One member of the Eco-Dentistry Association reports a reduction in materials costs of up to 30% after shifting to energy-conserving supplies.
Here are three steps each dental practice can take to reduce its dependency on disposables and save money:
(1) Switch to reusable infection control barriers and sterilization pouches made of cloth. Choose plastic-free, FDA-registered brands and follow the EDA’s Best Practices for Waste-Reducing, Pollution-Preventing Sterilization and Infection Control. (www.ecodentistry.org)
(1) Choose reusable rinse and swish cups. You’ll not only eliminate wasted embodied energy, but it is also a great way to reflect your practice personality. Some EDA members use small teacups; others use a glass shot glass!
(1) If you don’t choose reusables, choose compostables. Although disposable, compostable plastics are made from plants, rather than petroleum; they require less energy to produce and decompose relatively quickly.
The biggest bang for a dentist’s buck comes from a reusable item. The more times it is used, the lower the embodied energy cost, and the higher the return on your energy investment. Don’t forget that once an item’s life cycle is complete in the dental office, it doesn’t mean it’s ready for the grave. Many EDA dental practice members donate their reusable cloth items to animal shelters to extend the item’s life, contributing to meeting an important community need.
