| Complete Mix Digester |
The types of anaerobic digesters appropriate for your manure and food waste are:
RCM has co-digested dozens of different food wastes in full
scale digesters – including thin stillage, fats, oils, grease,
whey, grape juice, milk, paper, paper sludge, ice cream, fish
byproducts, breading, salad dressing, and waste fruit and
vegetables. RCM has also co-digested grease trap waste
as well as investigated wastes such as source segregated
Municipal Solid Waste (MSW) and proteinaceous
meat packing wastes.

Why combine food waste with manure?
• Food waste needs a place to go – most is hauled to landfills
• Food waste makes gas – some types make lots of gas
• Food waste can pay tipping fees to a digester instead of a landfill
• Farms have storage and land for nutrient management.
How much gas does food waste make?
• Gas production varies greatly between wastes. Production can be 2 to 10 times greater
per unit volume than manure.
Food Waste Rules:
• Not all food waste is equal.
• Waste means waste to whoever loaded the truck.
• Know your waste source
• Know your trucker
Doing it right:
• A digester should be designed to receive food waste.
• Operation is critical. Digesters don’t like too much food, heat or cold.
• Know what you are putting in the digester and what should happen.
Doing it wrong can result in:
• Upset or dead digester
• Stinky site
• Too much gas
• Not enough gas
• Overfull storage
• Over application of nutrients
The Issues:
• Zoning – What do you call a site where waste is being trucked in?
• Permitting – Will it smell, attract vermin and cause odor and flies?
• Storage – Is there enough?
• Nutrient Management – Can you manage extra nutrients from food waste?
