Etymology
芥 combines 艹 (plant) with 介, which likely contributes the sound. The character originally referred to mustard plants, and the 'dust/trash' sense may derive from the small, scattered nature of mustard seeds.
Meaning mnemonic
The plant top 艹 over 介 suggests tiny mustard seeds scattered like dust. Think of a plant whose small parts become trash when discarded.
Reading mnemonic
For カイ, imagine a kite (カイト) flying over a field of mustard plants, scattering seeds like dust: kite -> カイ.
