Scaling up Sustainable Practices: Sustainability in the Cruise Industry

Scaling up Sustainable Practices: Sustainability in the Cruise Industry

As cruise ships return to the seas after a long hiatus, cruise lines must continue to prioritise sustainability and the impact that cruise travel has on the world’s oceans. The good news is that with technological advances both on and off the ship, cruise lines are addressing environmental concerns.

Some of the big changes are coming from massive investment into cleaner fuels, such as Liquified Natural Gas (LNG), as well as utilising ‘shoreside power’, but onboard, the hospitality industry is also making moves to scale up sustainability efforts.

Everyday eco practices

The Hielo Wine Cooler, which requires only five ice cubes to keep a bottle sufficiently cool

Environmentally friendly procurement is one of the responsibilities faced by hospitality executives every day. When sourcing materials for cabins and restaurants, there needs to be a focus on cleaner, greener products – this could include anything from obtaining food and flowers for decoration from local destination outlets, to using energy-and-resource-saving products throughout the vessel, such as Cruise Ship Hospitality Expo exhibitor Hielo’s wine coolers, or exhibitor IPinium’s cooking pans.

Energy efficiencies

Cruise lines have a responsibility to go through all energy uses on the ship with a fine-tooth comb to ensure they are being as efficient as possible.

Celebrity Cruises is just one line that has installed energy-efficient window films across its fleet. These reduce heat loss throughout the vessel, reducing the amount of air conditioning required onboard. On top of this, all appliances are evaluated for efficiency; this includes TV’s, coffeemakers, ice makers, and galley equipment such as ovens and dishwashers. Cruise Ship Hospitality Expo suppliers such as ScanBox provide ‘heavy duty’ food carts made from aluminium; they are lighter in weight than your standard food transporter, reach target temperatures faster, and provide up to a 30% reduction in energy use.

Food for thought

With the largest cruise ships in the world preparing close to 30,000 meals a day, it’s hard to comprehend just how much food is needed, and sadly, also wasted. However, it’s a big focus for cruises lines – earlier this year, Carnival Corporation invested $1.8m in food digesters from BioHiTech Global, a sustainable technology services company, to be installed on 15 ships across the group. The “Revolution Series” digesters are equipped with BioHiTech’s analytics platform which provides data on weight and volume of food waste digested, the net food waste reduced, and the amount of CO2 reduced.

All cruise lines take recycling seriously and must be transparent in their efforts – for the past decade Norwegian Cruise Line has developed a recycling operation which reduces offload time of waste, truck on-site time, port congestion, transportation costs, and the use of pier-side containers. Viking Line has stringent recycling processes in place, and along with other solid materials, frying fat and electrical waste are taken to onshore recycling centres.

Cruise Ship Hospitality Expo exhibitor OilChef’s innovative deep fryer accessory lends a hand when it comes to oil waste; the device doubles the life of oil, meaning less changes of the oil fryer and less to carry onboard – significantly reducing oil waste (as well as improving food taste).

Moving forward, the cruise industry will continue to focus on more sustainable alternatives to products and processes and CSH is delighted to be working with a wide array of suppliers and brands who put sustainability first in their product development and wider company ethos.
