Today I decided to try working on this behavior with items other than paper. So I used a tin can. I started with simply shaping her to pick it up. It was a bit of a challenge, but she's a foodie and will do pretty much anything for more of it. No matter whether we continue this trick - it still works to the good if we ever get around to scent articles. It took probably 25 treats to get her to pick it up, carry it to the recycle bin and drop it in. Then we did it a few more times.
We'll practice this with a few other recycle items. Then I need to start moving the bin further away from me - inches at a time. Right now its almost in front of me, so its easy to get her to drop an item in it. Eventually I'd want her to pick up/take something and carry it to the bin.
We'll need that skill to get to my final goal of laying on the couch eating bon-bons while she collects up all the recycle stuff.
