A mixture of organic waste representative of the average composition
of municipal solid waste was used as initial substrate.
The composition and characteristics of the substrate used are outlined
in Tables 1 and 2. The mixed bio-waste was chopped (target
particle size 6 2 cm), portioned, and stored frozen. Dry matter of
the bio-waste was ascertained by drying at 105 C until constant
weight was obtained. Loss on ignition analysis at 550 C was used
to determine the organic matter content.
