Yesterday morning eight intrepid Timberland volunteers, including president Stewart Whitney, dove into a dumpster and sorted through the contents to identify key strategies for Timberland to reduce waste at its global headquarters in Stratham, N.H. Wearing polypropylene coveralls, gloves and protective eyewear, the volunteers sorted through 13 trash bags from the dumpster and assigned their contents to piles of recyclable waste, compostable waste, reusable waste and trash bound for the landfill.
