McDonald’s has announced the winners of its 2012 Best of Sustainable Supply Chain partners, who have risen to the company’s challenge of improving food sources, the environment, communities, and employee wellness across the world. Keystone Foods, JBS USA, and Tyson Foods were named among the 51 chosen.

Keystone Foods was selected for seeking to use alternative fuel for its delivery fleet.  Keystone Foods collected cooking oil from McDonald’s restaurants and converted the material into 100-percent biodiesel.  The fuel was then used for its delivery fleet.  JBS USA won for improving its sludge management process and reducing much of the environmental impact of its necessary wastewater treatment process.  Tyson Foods was selected for partnering with local businesses and nonprofit organizations to reduce the items being sent to area landfills where local infrastructure for cost-neutral recycling had not existed in some rural locations.  The company’s dedicated McDonald’s production facilities have accomplished a 43-percent reduction in waste materials sent to community landfills, an average of 165 tons monthly.

A panel of executives and external experts selected the final winners.  “The submissions in this year’s report demonstrate that McDonald’s supply chain is world class in its ability to provide safe, sustainable, and assured supply of food and products our customers love,” said Jose Armario, executive vice president, McDonald’s Global Supply Chain, Development & Franchising.
