In an effort to create more environmentally-friendly vacations,Norwegian cruise operator（挪威邮轮公司）Hurtig-ruten is making a plan to power its ships using dead fish, which will come from Norway's good fishing industry, to make shipping less wasteful.
So how do dead fish get transformed into fuel？Organic waste of any kind can be mixed to produce a type of fuel known as biogas（沼气），which can give off a bad egg smell. It's not a particularly attractive process, but don't worry： those smells won't be given off from your cruise ship's exhaust （排气管）. The raw materials in the biogas can be cleaned, which creates liquid biogas.
"What others see as a problem, we see as a resource and a solution," said Daniel Skjeldam,Hurtigruten chief executive. "By introducing biogas as fuel for cruise ships,Hurtigruten will be the first cruise company to power ships with fossil-free（无化石的） fuel."
Biogas is certainly cleaner than heavy oil,but it's not exactly carbon-free. So while the plan might be a creative way of making use of organic waste,as well as helping to get rid of fossil fuels,it's not a perfect solution. However,it's at least a step in a better direction. And the company will also be stopping single-use plastics on its 17 cruise ships. It's good to see change happening in a dirty industry.
