TRASH PILES ARE SHRINKING across the United States as a growing number of hotels are opting to divert waste previously destined for landfills. Adopting greener waste-management practices offers a handful of benefits. It aligns your property with state and local waste-reduction laws that, if not enacted in your area yet, likely will be soon. It demonstrates a commitment to environmental responsibility, which can be an appealing draw for socially conscious clients. And it can yield significant savings when done right.
“Diverting waste from landfills is a growing concern in our industry, and it’s smart business,” says Randy Gaines, vice president of engineering, housekeeping and laundry operations, Americas, Hilton Worldwide. That’s because diverting waste often results in bottom-line savings for a hotel. A few years back, Hilton Worldwide switched from delivering complementary print copies of USA Today to every room to instead offering digital editions of the newspapers automatically available on guests’ smartphones and tablets. Lower subscription costs aside, fewer newspapers in the garbage across all 12 of the company’s brands means much less waste and a subsequent slash in disposal costs.
Beyond offering e-newspapers, hotels have more opportunities than ever to taper the amount of trash targeted for landfills. As the nation as a whole pays more attention to reducing waste, organizations are cropping up to help businesses—hotels included—dispose more wisely. By working with such partners, Hilton Worldwide slashed its waste output across its property portfolio by more than 26% between 2009 and 2013 (exceeding a 20% goal the company had set). Combine that with additional reductions in energy use, water use and carbon output and the brand saved a staggering $388 million over four years. “We are saving a tremendous amount of money,” Gaines says.
If you’re looking to make a dent in your own property’s disposal costs, food waste is a good place to start. Because of its weight, food waste can be pricey since disposal fees are based on tonnage. Rerouting it strategically can cut costs significantly. That’s why so many full-service hotels, especially those with large banquet facilities, partner with local soup kitchens and shelters to donate unused yet perfectly edible food for people in need. Hilton donates used cooking fats from its kitchens to local farms, which use it for animal food. Many rendering companies also have an interest in such waste, which they also convert into animal food as well as cosmetics, soap and other products. Some provide storage barrels and free pick-up for hotels willing to donate.
Food waste that can’t be repurposed or donated can be composted on-site or even mechanically “digested” using an environmentally-friendly food digester. Machines like the Eco-Safe Digester from BioHitech America convert food waste primarily into water, which can be flushed through standard sewer lines. BioHitech America offers its digester via lease or purchase; the cost varies depending on a hotel’s specific size requirements. “In some areas of the country, waste transportation and disposal costs can be in excess of $100 per ton,” says BioHitech America CEO Frank E. Celli. “So a larger facility using one of our units can eliminate enough food waste to save up to $100 a day, which over time is fairly substantial. On that savings alone, our customers are sometimes capable of achieving paybacks in one-and-a-half or two years. So it offers a pretty attractive return on investment.”
Bulky, heavy mattresses—which, by the way, never decompose—can be recycled. In fact, mattress recycling is now mandatory in three states—Rhode Island, Connecticut and California. After a mattress is collected and filleted, the steel from its springs can be made into construction items, the foam into carpet padding and the cotton into insulation. Wood from the box spring can be chipped for mulch or burned for biofuel.
Since 2009, Hilton Worldwide has diverted more than 20,300 mattress and box springs from landfills through its partnership with Global Sustainability Solutions in Manassas, VA. Hotels embarking on renovations may see substantial savings by recycling mattresses rather than trashing them. “Nine times out of 10, we can beat the cost to landfill,” says Jessica Stracener, president of Global Sustainability Solutions.
Because landfill costs differ by region, the company provides cost analysis proposals to hotels interested in its recycling services, which—if clients prefer—include the installation of new mattresses as well as the removal of old. In its cost analysis for Hilton Worldwide, the company found it could recycle mattresses and box springs for an average $20 per set versus the $50 average it would cost to landfill them. “Also by using our services, you establish yourself as an eco-friendly property,” Stracener says, “which generates consumer interest and improves your brand image.”
Every day in the United States, hotels discard 2.6 million partially-used bars of soap. By collecting your property’s soap stubs and sending them to a non-profit recycling organization like Global Soap or Clean the World, you can not only whittle away dumpster waste, but also help combat hygiene-related illnesses, which claim more than 1.7 million lives a year globally. These soap recyclers convert used bars into new full-size bars, which they then send to developing countries or disaster areas where soap is scarce. Global Soap estimates that 1.4 million deaths a year could be prevented through simply hand washing with soap.
By forwarding soap scraps, hotels stand to benefit, too. “Hotels reduce their trash bills by diverting a considerable amount of waste from the trash bins each month. Then, by sending the soap and amenities to Global Soap, they’re able to take advantage of a couple of tax deductions as well,” says Executive Director Samuel Stephens. “The first deduction is any cost that a property incurs in getting the soap to our factory in Las Vegas—it’s considered a deductible charitable contribution. In addition, the soap itself is considered an in-kind’ donation, which is also deductible.”
Since 2009, Marriott International has donated more than 271,000 pounds of soap and 175,000 pounds of bathroom products through its Clean the World partnership. These have been recycled into thousands of hygiene kits that help children in impoverished communities around the world live healthier lives.
