Abstract:

With the many variables in local ordinances, economics, and health/pathogen regrowth questions, what is the future for digestion-based Class A systems in the US? Moreover, given this question, many POTWs are asking, “Are the benefits of a Class A process worth the costs?” This paper discusses the expected future of Class A digestion programs in the US, based on the current experiences of POTWs generating Class A biosolids and anticipated changes in land application rules, with regards to pathogen criteria, and discussions with utility, state and USEPA staff. This paper also describes land application rules and trends in Europe and the UK, and discusses whether similar trends are likely in the US. Information on POTWs with Class A digestion programs and issues associated with their application programs, drivers, obstacles, and costs where available, are also presented.
