Anaerobic digestion produces two main products: digestate and biogas. Digestate is produced both by acidogenesis and methanogenesis and each has different characteristics. These characteristics stem from the original feedstock source as well as the processes themselves.

== Digestate feedstock sources == Anaerobic digestion is a versatile process that can use many different types of feedstocks. Example of feedstocks can be from: Sewage sludges: Liquid sludge, untreated sewage sludge, composted sludge, and lime treated sludge. Animal wastes: Animal fats, animal blood, food remains, stomach contents, rumen contents, animal carcasses, and poultry, fish, and livestock manure. Energy crops: Usually corn, maize, millet, and clover. This can be whole crops used in co-digestion or as waste (stems and stalks) from harvesting of these crops. Municipal wastes: Food waste, coffee/tea filters, organic leftovers, bakery waste, and kitchen waste. Agricultural wastes: Fruits, molasses, stems, plant straw, and bagasse (residue after crushing sugarcane or sorghum stalks). Industrial wastes: Food/beverage processing waste, dairy wastes, starch/sugar industries wastes, slaughterhouse wastes, and brewery wastes.
