Sensor hand dryer: an eco-friendly bathroom essential

0

A series of recent life cycle analysis studies have brought new evidence to the debate between paper towels and hand dryers and it appears that contrary to popular belief, electric hand dryers may in fact be better for the environment after all.

LCA studies compared the environmental impact of electric hand dryers on measurements of electricity production and use, with the impact and emissions created during the production, manufacture and disposal of towels. in paper. The results revealed that high speed sensor electric hand dryers are better for the environment than paper towels.

But that doesn’t mean electric hand dryers are suitable for all projects. Speed, ease of use and environmental impact are important considerations, but so too is hygiene.

The importance of hand hygiene has been around since 1847, when Hungarian physician Ignaz Philipp Semmelweis discovered that cases of puerperal fever could be significantly reduced with the simple method of hand washing / disinfection.

Hygiene and hand washing are increasingly important today, especially in the health and elderly care sector where basic hand washing is neglected. and drying could have a significant and negative impact on the health of the patient or occupant. This is supported by studies from the National Institute for Health and Care Excellence and the Mayo Clinic which suggest that transmission of bacteria was more likely in cases of washed but not dried hands. Hand dryer maker Dyson also backed up these studies by suggesting that drying hands is just as important as washing, because wet hands can spread up to 1,000 times more bacteria on the surfaces they touch.

While there haven’t been as many studies on the benefits of hand drying, it’s important to note that not all hand drying methods have the same effectiveness or environmental impact. High speed electronic hand dryers are currently considered a greener option compared to the creation process and life cycle of a paper towel, but they are not proven to be better hand dryers. than paper towels.

Many electric hand dryers have features such as high speed air flow, reduced heating element wattage, and smart motor / airflow design.

The following is a guide to electronic sensor hand dryers available in the Australian market based on their environmental impact.
