London Heathrow Marriott to save million of liters of water annually

London Heathrow Marriott = is the first property in the Marriott UK group to partner with Granuldisk to trial a new technology that has so far saved 91.7 per cent of water used at the hotel. The London Heathrow Marriott wanted to reduce water wastage and conducted a study with Granuldisk, who placed meters in the hotel’s kitchen sinks.

Over a six month period, the meters showed a daily waste of 6,177 liters of water.  The installation of a Granuldisk pot-washing system, which includes an efficient utensil washer, has meant daily savings of 5,664 liters of water, 201.9 kWh of energy and 11.3 liters of chemicals.   

Using abrasive PowerGranules, water and a small amount of detergent, the blasting power of Granuldisk technology, combined with high temperatures, means that kitchenware is cleaned in a matter of minutes – using less water, energy and chemicals than traditional pot washing methods.

“As a large hotel, we’re keen to do what we can in order to reduce as much wastage as we can,” said Ron Vos, general manager at London Heathrow Marriott Hotel. “Once I learned about the benefits of the Granuldisk equipment and the potential energy and water savings, it made complete sense to have a truly efficient utensil washer installed.”

The London Heathrow Marriott Hotel has taken a number of steps towards reducing its carbon footprint. This includes investing in different equipment and devices to reduce energy and water consumption as well as implementing recycling schemes so that 100 percent of the hotel waste is recycled.   With its own windmill and a green house to grow herbs and tomatoes on the rooftop, the property has also been recognized by a number of awarding bodies, including the Green Tourism Scheme (Gold Award), the TripAdvisor Green Leaders Award (Platinum Award) and the Green Hotelier Awards (Highly Commended).
