Clean The World  


Clean World Hotel  

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 three short years, it’s become a global, charitable foundation with over 1,500 North American hotel and resort partners, diverting 1.7 million pounds of used soap from landfills and distributing 11 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 donated over 1,717 pounds of soap and bottled amenities so that 4,490 bars of soap could be distributed to children and families worldwide.

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 on the health of our planet.
