Sewers could be cool in blockheads do to all the blocks. It would work like this you place pipes under ground constructed by 2 steel bars. You would need to connect the pipes to your trash can. Once you place the items in don’t have to worry about them. The pipes could lead to a storage tank crafted by 6 iron blocks. Just a weird thought of mine!
Trash can connected to sewers? That would be a bit problomatic maybe. But I can see this being used for automation in storage depots.
I can see it being used that way too.
I Like The Idea. Very Creative
