that's not correct

several dozen is not several hundred

1 dozen = 12

55 us liquid gallons = 208,198 litres

the densities of metals are higher than that of

water ca 1 kg/l aluminum ca 2.7 kg/l steels and iron 7.5-8.5 kg/l brass 8.5-9 kg/l gold almost 20kg/l

several dozen kg is half a 55gal worth, maybe one...

EDIT for shavings:

https://www.mollet.de/info/schuettdichte-und-schuettgewicht....

iron and steel chips / shavings still are about 2 kg/l

aluminum is 200g / l

so one 55gal trash bin of aluminum shards is still about 40 something kg, four dozen.

thus for aluminum and aluminum only I stand corrected, it may be multiple trash bins.
