How to kill tree waste?

With which minecraft command can I kill the waste of the leaves of the trees? So how can I really only take away both sapplings and sticks?

Scissors for leaves

So you want to kill all dropped sticks and saplinges

Yes, but really only both.

That is the order

/ kill @e [type = item, nbt = {Item: {id: "minecraft: acacia_sapling"}}]

Now you just have to insert each sapling and sticks

Thank you very much
