More waste means more bio-methane means more cars can run on the stuff which, by the way, does not smell foul when it's burned in the car's engine

食物废料越多，意味着生物沼气越多，意味着存在更多汽车利用能源,而且汽车发动机燃烧这种能源不会散发恶臭气味。

The answer that B9 is proposing is a coastal cargo ship that combines massive carbon-fibre DynaRig sails - such as those used on the superyacht, the Maltese Falcon - with an engine that runs on bio-gas made from food waste using a process called anaerobic digestion.

The liquid bio-methane produced by this process can be used in an existing LNG engine.
