Pulitzer Prize-winning journalist and author Edward Humes found it ironic that Purdue University Northwest presented him with a bottle of water at the podium Thursday as he spoke about his book — “Garbology: Our Dirty Love Affair with Trash — and the Way Back.”

"This university and everyone I've met have been such a great host, but I've got to give you one little tip: If you have someone in to talk about waste, don't put this on the podium.

"It's the single-most wasteful product you'll ever see," he said, half-jokingly as he uncapped his own reusable water bottle. "These are so much easier to use."
