Improving reporting
Now tracking state-by-state in the U.S.

U.S.: We are improving the ways we track our progress. For example, to the best of our knowledge, we have reported an overall annual waste-reduction percentage for the entire U.S. But through a new tracking program piloted in California, we will soon be able to track and report waste-reduction numbers on a state-by-state basis.

According to this new tracking program piloted from January through October 2010, reports indicate we are averaging a redirection rate of 81 percent across California. We have since rolled this program out to each state and anticipate having a U.S.-wide redirection rate with similar results.

Our first effort to create a trash generation versus recycle rate was in February 2009. At that time, we tracked only approximately 30 waste streams for an estimated redirection rate of 64 percent. Today, we track nearly 138 waste streams.

We continue to partner with NGOs to define new opportunities and evaluate our sustainability programs. By progressing toward our goal of producing zero waste across our global operations, we are creating opportunities, promoting sustainable lifestyles and improving quality of life for everyone.

Eliminating waste across our global operations

U.K.: 2010 was a banner year for ASDA, as it successfully redirected 86 percent of its overall operational waste through store process to segregate key materials such as food, plastic and cardboard. In doing so, more than 200 of our stores in the U.K. have realized our core sustainability objective of producing zero waste. Key accomplishments in 2010 include recycling of 165,097 tons of cardboard, 17,463 tons of plastic and 1,431 tons of oil converted to biofuel.

Argentina: Walmart Argentina realized a 63 percent reduction in plastic bag waste in 2010 (2007 baseline). While Argentina's progress represents three years of focus in this area, the Ecologic Checkout program it piloted at Bahia Blanca in 2009 and rolled out to all of its Changomas and Walmart stores in 2010, has proven to be a major win. This program dedicates one or more plastic bag-free checkout lanes per store.

China: Our Walmart China operations reduced plastic shopping bag waste in our stores by 84 percent in 2010, compared to a 2007 baseline.

Through the implementation of waste water reclaim systems, sensor faucets, pressure-reducing valves and passive-use strategies, we have reduced water usage by 54.2 percent since 2005. In addition, we reduced waste generated in our stores and operational facilities by 49 percent, compared to our 2005 baseline.

Mexico: Walmart de México recovers the cooking oil used in 242 of our restaurants throughout the country. We work directly with a host of suppliers who transform the oil into biodiesel, soap and a supplement for cattle feed.

US waste reduction in California

Canada: In March 2010, the Walmart Canada home office in Mississauga, Ontario, achieved near-zero-waste status, followed by the Bridgewater store in July 2010. Bridgewater was the first Walmart Canada store to achieve near zero waste, which is an accomplishment that earned it the Mobius Award for Environmental Business of the Year from the Resource and Recovery Fund Board of Nova Scotia.
