Giving Compass' Take:

• The Guardian reports that wasted fish parts will be used to power ships in a new green energy initiative by Norwegian cruise line Hurtigruten. The company is also banning single-use plastics.

• While upcycling sea life may seem a little out there, could this be inspiration for other companies looking to create sustainable innovations here in the U.S.?

• Here's how we can cut down on waste with packaging made from plants.

The leftovers of fish processed for food and mixed with other organic waste will be used to generate biogas, which will then be liquefied and used in place of fossil fuels by the expedition cruise line Hurtigruten.

Heavy fossil fuels used by ocean-going transport are an increasing problem as they are even more polluting than fuels for land-based vehicles, emitting sulphur and other contaminants. The fuels contribute to air pollution as well as to climate change. Converting vessels to use biogas will cut down on pollutants and reduce greenhouse gas emissions.

Hurtigruten operates a fleet of 17 ships, and by 2021 aims to have converted at least six of its vessels to use biogas, liquefied natural gas — a fossil fuel, but cleaner than many alternatives — and large battery packs, capable of storing energy produced from renewable sources.
