Walmart and TerraCycle are sponsoring the Trash to Cash Collection Contest, a program that will reward the top-collecting New Jersey public schools with $125,000 in grants. The contest is open to any public school in the state. The schools that collect the most used packaging and products through TerraCycle's free Brigade programs will receive grants ranging from $5,000 to $50,000. The contest runs through Dec. 15, and the winners will be announced in early January.
