-- Tonight's installment of "Garbage Moguls" (8 p.m., Saturday, National Geographic) follows the intrepid employees of TerraCycle, innovative recyclers and product designers who fashion new items out of the stuff the rest of us throw away. Tonight's challenge is to make a line of pet products from discarded dog-food bags.

GARBAGE MOGULS — After they are approached by the Pedigree company, the young mavericks of TerraCycle stretch their imaginations to create an entire line of pet products fashioned from dog food bags, including toys, leashes and collars, dog beds, and even clothes for canines. After several product designs falter, though, the team is thrown into a last-minute scramble for viable products to pitch. (8 p.m., National Geographic Channel)

This new docu-reality series follows an ingenious group of eco-capitalists at TerraCycle, Inc., a green business that creates and sells products made from non-recyclable waste materials. In the first episode of a three-hour marathon, Pedigree challenges the TerraCycle crew to develop a line of pet products. With a strict two-week deadline, the participants quickly get to work, collecting hundreds of old dog-food bags and using them to make a variety of products, from leashes and collars to dog toys and rain gear. The other episodes' tasks: build a garbage can from potato chip wrappers, design fishing lures from old CDs and make a suit jacket out of Target shopping bags. — Karen Andzejewicz
