Sustainability By The Negombo Lagoon
Resting upon the edge of one of the western province’s most prominent water bodies, our commitment to a number of sustainable initiatives is both natural and complementary. With a focus on energy, environment, and efficiency, Jetwing Lagoon has not only invested in dedicated infrastructure, but also holds the honour of a few firsts, which reflect our celebrated standing as a true believer in responsible tourism.
Our annual (2021) Sustainability Performance Report
Energy and Carbon
Jetwing Lagoon is the first institute in Sri Lanka to feature 100% LED lighting. LED bulbs are used across the property, including the garden and swimming pool, as they are more energy efficient than both CFL and incandescent bulbs.
In addition, the hotel also features two roof-mounted solar photovoltaic systems. The 20 kW off-grid system provides all the electricity needed for the illumination of your room, with a dedicated in-room indicator to show when solar or grid power is being used. The 10 kW grid-tied system however, provides energy for the hot water circulation and distribution pumps of our onsite biomass boiler, and was also the first grid-tied system in our family of hotels when it was installed in 2012.
Another honour in the same year includes the establishment of the first vapor absorption chiller (VAC) in a Sri Lankan hotel. Sustainably operated via steam generated from the onsite biomass boiler, the VAC provides air-conditioning for the entire property with a capacity of 100TR. It is also worth mentioning that the VAC consumes only 7 kW of electricity, compared to approximately 88 kW, which would be consumed by a conventional chiller of equal capacity.
The biomass boiler is fueled by sustainably harvested cinnamon wood, and operates 24 hours a day to produce up to 1500 kilograms of steam per hour – most of which is used to operate the VAC, as well as for hot water generation during the night.
Finally, the central hot water system of the hotel is operated completely on renewable energy. With 50 flat plate collector-type solar panels, the system is able to provide all the hot water required for hotel operations between 9 AM and 4 PM, while steam from the biomass boiler generates hot water during the night.
Water and Waste
The onsite effluent treatment plant at Jetwing Lagoon allows us to treat 100% of wastewater generated through hotel operations. Ensuring that all produce is put to sustainable use, treated water from the plant is used for garden irrigation and the operation of our cooling towers. Storm water collected from the entire property is also diverted to a collection pond, which aids in groundwater recharge.
In addition, while an enhanced composter at Jetwing Lagoon processes all food waste from our kitchens and restaurants within a rapid digestion process of 21 days; all garden sweepings and other tree clippings from the hotel gardens are composted using a traditional above-ground compost pile. Compost produced from both processes is then used as a nutrient-rich soil enhancer in our hotel garden.
Sourcing and Production
Separated from the expansive lawn at Jetwing Lagoon, the establishment of an organic garden enables us to make optimal use of our greenery by growing local fruits and herbs whenever possible. This very produce is then later used in our hotel kitchens, where it contributes toward the creation of mouthwatering meals that are served to you. Additionally, Jetwing Lagoon also makes use of sustainable glass water bottles, which are sourced from our own bottling plant operated by our family at the nearby Jetwing Blue.
