The Great Giveback Chicago landscaper, ecologist and urban poo-pioneer Nance Klehm took waste recycling to the community scale with her “Humble Pile” project: For three months, 22 participants pooped into 5-gallon buckets instead of their toilets and brought them to Klehm to be emptied into aerated 32-gallon garbage cans in an undisclosed location. After 11 months, the 50 garbage cans were dumped into one large pile. After another year of composting with only comfrey and some old straw, Klehm delivered a fluffy compost — that tested negative for fecal bacteria — in 2-pound bags printed with “The Great Giveback.”
