Sellers Markets has reached its goal of composting 500,000 pounds of materials and waste in the same year the local, sustainable San Francisco chain is turning five.

"From day one, we set out to be one of the most environmentally responsible businesses in the United States," said Deb Sellers, co-founder of Sellers Markets, in a press statement. "Reaching one-half million pounds of composting, in just five years with the help of our loyal customers, is just one measure of our green success."

At each of Sellers Markets' three San Francisco locations, compostables are collected in the kitchens and dining rooms. In addition to food scraps, all of the to-go containers, packaging, drink cups and disposable cutlery are compostable. According to Sellers Markets, 90 percent of its food and beverages are locally sourced, sustainable and organic. Its green initiatives also include a recycling program for non-compostable waste, food bank drops for any consumable foods and restaurant interiors that are built using recycled and reclaimed materials.
