State Summary

● Biosolids composting and other Class A EQ treatments are common and popular in the small state of Delaware, with the biosolids products used locally and new biosolids facilities being developed for additional EQ production.
● Delaware's Class B biosolids, including Wilmington’s, are mostly land applied out of state (e.g. in Pennsylvania).
● Delaware’s biosolids regulatory program is robust and is influenced by nutrient management requirements in Pennsylvania and other regional destinations for biosolids.
