TRENTON -- With a blockbuster deal announced yesterday afternoon, in a modification of the age-old adage, TerraCycle's trash has become Walmart's treasure. The Trenton-based manufacturing firm said a large number of its products, all made from recycled packaging material, will be available for sale at Walmart stores nationwide. The deal is a huge step up for the rapidly growing city firm. "We've done enough good business with them in the past that this is them giving us our shot at the big time," said Albe Zakes, the company's vice president of communications. "This is a major opportunity for TerraCycle. If it goes extremely well, then it means that Walmart is going to want to do more business with us."
