DATA COLLECTION GOALS• Identify the number and location of AD facilities
• Document processing capacity & track it over time
• Types of feedstocks and sources
• Amount of food waste processed
• Amount of biogas produced
• Analyze the end-uses of AD products
SCOPE OF FACILITIESStand Alone On-Farm WRRF
RESULTS• Location Data• Response Rates• Processing Capacity• Food Processed• Biogas Production• Operational Dates
