Effectiveness of microbial inoculants from tempeh and tapai in home scale composting

This study evaluated the effectiveness and necessity of microbial inoculants on home scale composting (food waste: rice bran: dried leaves 2:1:1) with the attempt to divert food waste from the landfill. In this study, the feedstock was inoculated with three formulations of microbial inoculants (MI)...
