This research looked at the need for ligno-cellulolytic inoculants (EM bacteria and Trichoderma sp.) in small to medium scale composting of household wastes. A mixture of household organic waste comprised of kitchen waste, paper, grass clippings and composted material was subjected to various durations of thermo composting followed by vermicomposting with and without microbial inoculants for a total of 28. days. The results revealed that ligno-celluloytic inoculants are not essential to speed up the process of composting for onsite small scale household organic waste treatment as no significant difference was observed between the control and those inoculated with Trichoderma and EM in terms of C:N ratio of the final product. However, it was observed that EM inoculation enhanced reproductive rate of earthworms, and so probably created the best environment for vermicomposting, in all treatment groups.
