making concrete could be a more efficient way to make blocks, or alternatively, could make a reaction that makes water+lava at the same time. (Would that even work?

)
Bee keeping isnt really a non-useful thing as I see it, honey is a very useful product and does not go bad. (whether or not it does in game however I do not know)
Honey has been used in the past to preserve some foods as well, I remember hearing about people pickling apples with honey or some such.
Do wax crafts exist as current?
wax and soap toys wouldn't be a bad idea.
Pressing soap would most likely be able to do something, like returning soap to oils to be used else where
The bee armor might be onto something actually, bees naturally make their hives don't they? Wait no I'm thinking paper wasps perhaps.
Either way, it might be able to get paper/fabric from bees somehow, but anything that would be able to actually protect you would likely need a fair bit more work.
Wax has been used with leather in the past to make a hardened leather
