December 21, 1999 marked the tenth anniversary of McDonald's USA and the Environmental Defense Fund (EDF) and their groundbreaking alliance in 1989. Their partnership has replaced polystyrene foam sandwich clamshells with paper wraps, and light-weight recycled boxed, replaced bleached with unbleached paper carry-out bags, and made dozens of other packaging improvements behind-the-counter in McDonalds restaurants and throughout the company's supply chain. The results of the task force far exceeded their expectations and original goals. What started as a cautious venture for both parties, ended in a successful partnership. The task force produced a Corporate Waste Reduction Policy and a comprehensive Waste Reduction Action Plan, both, which have shown great results. Since 1991, the team eliminated 150,000 tons of McDonald's packaging, purchased more then 3 billion dollars worth of products made from recycled materials, and recycled more than 2 million tons of corrugated cardboard. This commitment from McDonalds has decreased restaurant waste by 30%. McDonald's now uses reusable plastic trays for holding sandwich buns in place of corrugated containers and large steel canisters for storing coke in place of cartons. The wraps provided a 70-90% reduction in packaging volume resulting in less space consumed in landfills. After receiving such substantial results from the waste reduction project, McDonald’s announced the further expansion with EDF and other outside experts to set goals by Earth Day 2000 to reduce energy us in restaurants, with a target of at least 10% reduction, compared to 1999., "When we launched our alliance ten years ago, I don't believe either one of us could have imagined the scope of the results we are announcing today," Jack Greenberg said. "Working with EDF, McDonalds is proud of the tangible difference we have made for the environment in just ten years." Their Landmark project showed both business and environmental activists that they can share the path toward a more sustainable society.
