Green Partnerships - Clean the World

Clean the World

In 2012, we partnered with the Clean the World Foundation to recycle our soaps and shampoos. Clean the World began in 2009, with the simple goal of recycling soap from the hospitality industry to then place soap in the hands of children around the world. In just a few short years, it’s become a global, charitable foundation with over 1,500 North American hotel and resort partners, diverting over 16 million pounds of used soap from landfills and distributing over 44 million soap bars to people in 55 countries and the U.S. Through this partnership, we recycle bar soap, shampoo, conditioner, lotion and bath gel to create new amenity products. To date, we have contributed to Clean the World by:

  • Collecting 8,281 lbs of waste
  • Distributing 20,057 soap bars
  • Recycling 3,390 lbs of plastic
  • Collecting 9,040 plastic bottles for hygiene kits

Earth Hour

For the last four years, the Sheraton Portsmouth Harborside Hotel has celebrated Earth Hour. Earth Hour gives our hotel the opportunity to take part in the biggest ever global event in the fight against climate change, and to demonstrate to our associates, guests and suppliers just how important simple actions can be towards saving energy and reducing our greenhouse gas emissions. Earth Hour symbolizes that working together each of us at the hotel can make an impactful difference in the health of our planet.
