Composting Food And Yard Waste Atop A Landfill<\/h2>\n

The City of San Diego (CSD) was composting up to 100,000 tons of green waste material per year using turned windrow technology. As food waste was being added as a new feedstock, and because of the contamination from their automated curbside collection process, the City wanted to evaluate in-vessel technology for the purposes of composting mixed green waste and food waste.<\/p>\n

THE SG SOLUTION<\/strong><\/h3>\n

Pilot Scale Demonstration Project<\/strong><\/p>\n

Since food waste was added as a new feedstock, and because of the contamination from their automated curbside collection process, the City wanted to evaluate in-vessel technology for the purposes of composting mixed green waste and food waste. After several alternative methods were evaluated, the City chose to implement an SG MOBILE\u00ae System with GORE\u00ae Cover (covered aerated static pile) Pilot-Scale Demonstration Project in 2009.<\/p>\n

    \n
  • Food Waste Composting: Compost a new feedstock \u2013 commercial, institutional, and residential food waste.<\/li>\n
  • Evaluate the ability to produce a high-quality finished compost while controlling Odors, GHG Emissions, Leachate, Moisture, and Vectors.<\/li>\n
  • Meet or exceed local, county, and state regulations.<\/li>\n
  • Evaluate the operating capability and simplicity of the technology.<\/li>\n
  • Develop a model for the total cost to build and operate the composting technology.<\/li>\n<\/ul>\n
