This paper presents a framework that has been developed from evaluating
anaerobic solid waste digestion. To develop the framework, a review of
the preformance of digestion processes was first conducted. Because the
data presented were for very different operational parameters
(retention time, temperature, configuration set up, mixing, ect.) as
well as substrates used for digestion, a standard methof os comparison
waas developed. Gas production per Mg input, organic loading rate and
percent volatile solids removal were itentified as useful standard
parameters for evaluating the performance of different technologies.
This framework was constructed as a spread sheet and can be used for
different set ups (configuration, organic loading rate, ect.) and with
different substrates. It can predict, based on the input and using mass
balances, the mass of products of the digester including biogas,
treated solids and water. This framework provides a useful tool for
evaluating the technical capabilities of different technologies,
predicting the quantity of the products, and ultimately, making
decisions as to which technologies best meet local needs.
