Here's a video from my state Department of Ecology explaining why you shouldn't do this, and why you are actually making it worse for everyone. Cursory web searches on the topic say the same thing. Bagged recyclables can't be sorted so they just get diverted to landfill.

You could actually make the world a better place by throwing your bagged recyclables in the trash because then you aren't actively harming the recycling process.
