Anaerobic Co-Digestion: Feedstock Sampling and Characterization

This fact sheet provides basic considerations for co-substrate handling, sampling, and characterization for an optimized co-digestion process at a WRRF. It should be noted that this fact sheet mainly focuses on readily available high-strength organic wastes such as source separated organics, food waste, fats, oils and grease (FOG) that are commonly co-digested with wastewater residuals.
