This economic benefit will get even better in coming years. Water and electricity aren’t getting any cheaper. While scarcity creates economic pressure where not enough supply is available to meet high demand, even conservation can raise costs. Our TRSA members (outsourced laundries) and other industrial users of sewer systems have experienced this with local publicly owned treatment works (POTWs).
High-volume wastewater dischargers are large water users so they are focused on reducing consumption. In using less fresh water, their sewage discharges are less diluted (i.e., more concentrated), which creates economic challenges for POTWs:
- Less revenue, as they bill dischargers based on gallons discharged to them
- Higher infrastructure expense for technology to treat more concentrated waste streams
Michigan State University forecasts a 41% increase in the cost of water over the next five years. The price of natural gas rose 72% in the six months between April and October 2016 and is anticipated to rise another 4% by 2018, according to the US Energy Administration, with electricity prices on the same growth path.
A hotel will shoulder these burdens on its own for linen processing unless it outsources this function. Linen, uniform and facility services are far more capable of absorbing such price increases. Since the late 1990s, TRSA members have reduced gallons of water needed per pound of laundry 33% on average. Some have been able to do 40 to 50% better than that. Average energy consumption per pound has fallen 27% in that time and some TRSA members have done 30 to 40% better than that.
Hotels can be assured of achieving such significant environmental gains in linen processing by contracting with a TRSA-certified Clean Green laundry. To receive this designation, a laundry’s water and energy conservation success must be gauged. The certification aligns with the ASTM International standard, “Guide for Sustainable Laundry Practices,” which recognizes Clean Green’s key criteria as universal indicators of maximum sustainability in commercial laundry work.
