Environmentally Preferable Purchasing at Yellowstone National Park

  • In 2012, we will be rolling out a new bulk amenities program at Mammoth and Grant. This program, which helps to eliminate waste through refillable in-room amenities, will continue to help eliminate unnecessary materials from entering our waste stream.
  • Implemented a sustainable amenities program in 2008 (the first in the National Park system) that features bottles made primarily from Plastarch Material (PSM), a corn-based biodegradable material; as a result we will divert on average 280,000 plastic bottles (or almost 9 tons) from the landfill annually. Vegetable-based soaps are cruelty-free and contain no animal fat or byproducts, and cartons are made from natural recycled packaging printed with soy-based inks.
  • Uses laundry bins made out of post-consumer plastic products.
  • Purchases recycled paper and use soy-based inks in our printing operations. We have removed all non-recyclable paper (neon colors) from our print shop.
  • Purchases environmentally sensitive paper products that use 100% post consumer content and are bleach free. Includes all toilet tissue for more than 2,200 guest rooms, campgrounds and RV parks; towels for dispensers at all properties and restrooms; and, napkins in employee dining rooms and cafeterias.
  • Switched all of its pens in lodging services to Bic Ecolutions that are made from 75 percent pre-consumer plastic.
  • Reviews all new chemicals introduced into our park operations for environmental attributes through our Chemical Review Committee.
  • Utilizes non-hazardous water-based solvents for parts and brake cleaning in the Service Center. Mechanics also use non-chlorinated and refillable spray bottles instead of aerosol cans for brake and carburetor cleaner, and recap old truck tires to extend their life.
  • Purchases Green Seal eco-friendly cleaning chemicals.
  • Converted vehicles to propylene glycol motor coolant (from ethylene glycol) to reduce potential toxicity to wildlife.
  • Purchases used books and research materials for training programs wherever possible.
  • Eliminated all Styrofoam drinking cups from operations.
  • Lodging has begun purchasing pillows made from recycled plastic, has also tested a number of eco-friendly shower curtains, and has begun phasing in non-PVC plastic materials
  • In 2009, began purchasing compostable disposal utensils, cups, and to-go containers for our restaurants. This will divert 12 tons of material from the landfill annually.
  • New in-room guest services directories are made from recycled craft paper, the quarterbind spine is recycled leather, the laminate is an environmentally responsible laminate, and the screened decoration is an eco-friendly ink.
  • Replaced most canned air with electronic dusters, eliminating a frequent waste.
  • Replaced disinfectants for most departments with Pure Green 24, a product that contains no alcohol, bleach or other toxic ingredients and its manufacturing process produces zero discharge with no waste or byproducts. PureGreen 24 is manufactured from Silver Ions, Citric Acid and Purified Water.
