Walmart is struggling to find the material to meet its goal to use 3 billion pounds of recycled plastic in its packaging and products by 2020. “The problem is supply,” explains Rob Kaplan of Walmart.Most recycled materials should be cheaper than virgin commodities, but America throws too much stuff away. Low landfill fees and a fragmented waste-management system have kept the country’s recycling rate at around 34% for two decades—far lower than most rich countries. This waste comes at a cost.
