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

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

Prince George\u2019s County implemented an SG MOBILE\u00ae System with GORE\u00ae Covers (covered aerated static pile) Pilot-Scale Demonstration Project in 2013 as a way to test the following:<\/p>\n

    \n
  • Green Waste Composting<\/li>\n
  • Food Waste Composting<\/li>\n<\/ul>\n

    Of significant importance to the Pilot-Scale Demonstration Project was that the 8-week SG MOBILE\u00ae System process outperformed the existing 8-month windrow turning process for quality, time to manufacture, and performance.<\/p>\n

    In addition, the demonstration validated Prince George\u2019s County\u2019s ability to compost food waste at mix levels up to 50%, resulting in a quality product manufactured within quality specifications with positive results for odor control. Finally, the demonstration project validated positive results for operational modeling and ability.<\/p>\n
