Philadelphia Looking for Information and Feedstock to Co-Digest Food Waste

The Philadelphia Water Department (PWD) issued a request for information (RFI) concerning potential methods of co-digestion of food scraps with wastewater at either of two water resource recovery facilities in the city. 

These two of the cities wastewater processing plants currently have on-site biogas facilities that also create Class A biosolids, but the facilities have excess capacity. PWD particularly aims to accept pre-processed liquefied material.
