Are hand dryers more environmentally friendly than paper towels?
The Slate tells us that hand dryers are the greener choice in about 95 percent of circumstances. The Climate Conservancy reports that for each use, hand dryers cause between 9 and 40 grams of carbon dioxide emissions, whereas paper towels have an average of 56 grams of carbon dioxide emissions.
Why are paper towels more hygienic than hand dryers?
Hand dryers sometimes use speeds of over 370 miles per hour (mph), spreading pathogens as far as five feet from the drying unit. Those pathogens can also linger in the air for up to 15 minutes. Paper towels lower the risk of spreading pathogens through the air, reducing the risk of contaminating nearby surfaces.
How much more do paper towels cost over the life cycle of a building VS high speed energy efficient hand dryers?
Our research shows that using hand dryers instead of paper towels generates up to a 95% cost savings over paper towels. Unlike a single investment in high-efficiency hand dryers, a commitment to stocking paper towels means an endless loop of repetition and expense, from creation through disposal.
Are air dryers more sanitary than paper towels?

Which method of drying your hands has the biggest carbon footprint?
The research paper compared the seven most common drying methods in public toilets and concludes that paper towels and warm air hand dryers have the highest environmental toll – generating 70% more carbon emissions than the newest technology on the market, the cold air-driven hand dryer from UK manufacturer Dyson.
Why are air hand dryers unsanitary?
Petri dishes exposed to bathroom air for two minutes with the hand dryers off only grew one colony of bacteria, or none at all. However, petri dishes exposed to hot air from a bathroom hand dryer for 30 seconds grew up to 254 colonies of bacteria (though most had from 18 to 60 colonies of bacteria).
Is it safe to use hand dryers in public restrooms?

What happens to paper towels after they are used?
Some factors to consider with paper towels are the material they are composed of and where they go after use. Most go to the landfill, where methane, a greenhouse gas, is produced during decomposition. Adding to that waste are the trash can liners, which are also put into the landfill after they are filled and then replaced again.
