Abstract
Official abstract text for this publication.
Waste, such as municipal solid waste (MSF), is separated into a wet fraction and refuse derived fuel (RDF). For example, the waste may be separated in a press. The wet fraction is treated in an anaerobic digester. The RDF is further separated into a cellulosic fraction and a non-cellulosic fraction. The cellulosic fraction is treated by pyrolysis and produces a pyrolysis liquid. The pyrolysis liquid is added to the anaerobic digester.
First claim
Opening claim text (preview).
We claim: 1. A process for treating solid waste comprising steps of, separating the waste to produce rejects and a wet fraction; separating cellulosic rejects from the rejects; and, treating at least a portion of cellulosic rejects by anaerobic digestion. 2. The process of claim 1 further comprising co-digesting the wet fraction with the at least a portion of cellulosic rejects. 3. The process of claim 1 wherein the step of separat…
