Optimize Water and Energy Usage in Hotel Laundry Machines

Optimize Water and Energy Usage in Hotel Laundry Machines

Laundry machines are one of the largest sources of water consumption in hotels; consuming as much as 1,400 gallons per load. This is why it is so important that they optimize water and energy usage

The hospitality industry is one of the heaviest users of laundry machines. Everyday, thousands of pounds of laundry are washed in hotels worldwide. While it is important to provide guests with clean and hygienic linens and towels, it is equally to optimize water and energy usage.

The basic principle behind the operation of typical laundry machines is a rotating drum to agitate the laundry with water and detergent during the wash cycle. After the wash cycle, fresh water is used for final rinse prior to water extraction via high speed rotation.

Types of Laundry Machines:

There are generally two types of laundry machines: top-loading and front-loading machines. Front-loading machines use less water and detergent than top-loading machines since they do not require filling the entire drum which is required in top-loading machines. Front-loading machines can use 60 per cent less water than top-loading machines. As an added bonus, front-loading machines can be stacked, which saves space.

Water Consumption:

Commercial laundry machines range in size from 25 to 400 dry pounds of laundry per load and use anywhere from 2.5 to 3.5 gallons of water per pound of laundry. This can translate to as much as 1,400 gallons of fresh water per load which is a significant quantity of fresh water.

Ways to save water:

One practical method of saving water is by installing a computer-controlled rinse water reclamation system. This system diverts the rinse water to a storage tank for later use as wash water for the next laundry load. Rinse water reclamation systems can reduce water usage by up to 30 per cent compared to standard machines that discharge the rinse water to the sewer.

Another simple yet highly effective method for reducing water consumption in hotels is by educating guests about the environmental footprints of laundry operations and by encouraging guests to minimize the requirements for fresh towels and linens. It is estimated that an average-sized hotel comprising of 150 rooms can save as much as $30,000 annually in operating costs if 65% of its guests simply participate in a linen-reuse program.

The nice feature about education campaigns is that they require minimal investment. In addition, promoting water conservation and enhanced environmental footprint projects a positive image of the hospitality establishment and its commitment to sustainability.
