Lately I’ve been extending the already large capacity of my 5 gallon garbage can by using 2 buckets to compact trash.
Both buckets should be exactly the same size and shape so they can nest nicely into each other.
I call bucket A my “trash bucket” and bucket B my “squish” bucket. I keep a lid on the “squish” bucket so I can sit on it to let my own 180 pounds cram an entire can into one compact sedimentary layer.
I find that this doubles or triples what I can stuff into 5 gallons.
Since I compact it so dense, I use a stick or pole to pull it all out once I’m finally ready to take it to the dumpster.
