A study of canned mackerel and herring shows that the production of the aluminium can is responsible for most of the products carbon footprint (Buchspies et al. 2011).

This allows worms for fish food, a place to make use of food waste, it gives valuable organic liquid and solid fertilizers that can be used for wheat grass or other edible plants.
