Alpha Transparency on dust clouds

Hello everyone! I know this has probably been answered many times, but I need help with these clouds and I can’t get them to work!

I was to make dust rise up as someone slides on the ground. It’s a cartoon celshaded look.
I made a glyph with a transparent texture, but these clouds are on one sheet and need to be separated into different
planes from one image. Thank you! Here is my problem.

(They also do not need to have any shadow)

Any idea on what I can do to remove the white box in the render???
