This is my second visit to Recology SF; AKA the San Francisco dump. San Francisco has a massive recycling program that includes compost. Recology is where the sorting happens. In addition to having educational programs about recycling and waste management, they have supported an artist in residence program since 1990. Here are a few pieces that caught my eye.
Bonus pic! This hawk is a member of the staff at Recology. It's job is to keep the seagulls from nesting on the grounds. Our tour included an introduction to this natural pest control solution that I found fascinating.
