Explaining the recycling process

You've seen the heartbreaking video. Plastics plaguing our oceans and so many wanting to help. Viewer Robin Taylor has been recycling for decades and sent in a question to Angela Answers and she wrote,

"My question has to do with recycling plastic. I've been recycling for 30 years now and I read that 80% of the plastics we recycle are just thrown in the garbage due to not being 'clean'. I would like to know what we are doing wrong in our recycling efforts."

Allyson Mitchell, the Executive Director at Indiana Recycling Coalition has the answers to tell us how to make a difference.
