How Much CO2 Do We Use Drying Our Hands?
A conventional hand dryer uses warm air to dry your hands. This warm air is blown out of the dryer and helps water to evaporate as you rub your hands together. It might take around 30 seconds to dry your hands in this way, and electricity is being used constantly. The amount of electricity used by a typical energy efficient hand dryer is equivalent to just under three grammes of CO2. This might not seem like much, but over the course of a year in a busy office, hand dryers may be used up to 500 times each day, which results in around 526 KG of CO2 being released into the atmosphere.
The production, transportation and disposal of paper towels is even more Carbon Intensive. The carbon footprint of each paper towel is more than seventeen grammes! This means that in the same situation as above, paper towels will contribute more than 3 Tonnes of CO2 to the atmosphere, not to mention the number of trees cut down to make the paper, and their contribution to landfill.
The Mitsubishi Electric Wave u02 hand dryer does not rely on a heater. Fast moving jets of air are blown over your skin to displace water and dry your hands. This method of drying, coupled with an ultra-efficient fan design means that the carbon footprint is much lower. On average, using a Mitsubishi Electric Wave u02 will result in less than 1 gramme of CO2 being released. Over the course of a year in a busy office, this translates into just 160 KG of CO2 – around 5% of the carbon footprint of paper towels.
