Top-Loading Machines vs. Front-Loading Machines
- Front loading machines, like the ones here at Middlebury, use less energy and water.
- About 85% of the energy consumed by a washing machine goes to heating the water, so switching to cold water saves more energy!
- Wash agitators in top-loading machines require more energy and induce more wear and tear on clothing, while also providing less room for larger items like rugs and comforters.
- Emissions from washers and dryers include components have been shown to classify as hazardous air pollutants and known/probably carcinogens.
- In a 2011 study, investigators identified 29 volatile organic compounds (VOCs) in the dryer-vent emissions.
- The US Environmental Protection Agency (EPA) classifies seven of the VOCs found in dryer-vent emissions–acetaldehyde, benzene, ethylbenzene, methanol, m/p-xylene, o-xylene, and toluene–as hazardous air pollutants.
- One laundry detergent brands’ acetaldehyde annual emissions is 1,660lb. Automobile emissions of the same chemical are approximately 56,000lb/year. Looking at the top 5 laundry detergents, emissions of acetaldehyde represent 6% of automobile emissions.
- Mice exposed to emissions from fabric-softener products experienced trouble breathing and other irritation.
What You Can Do
- Do fewer laundry loads!
- This will use less water and less energy.
- Switch to cold water (save energy!).
- Continue using front-loading washers.
- Stop using fabric softeners, or switch to more environmentally-conscious brands.
- Stay away from laundry products packaged in plastic.
