Abstract

A system for effective garbage decomposition using sawdust and aerobic soil bacteria was examined. The machinery used in this process, the garbage automatic decomposer-extinguisher (GADS), is composed of a container with an automatic mechanical mixer and a drain for liquid formed by the decomposition of garbage. The aerobic soil bacteria, cultivated in sawdust, degrades garbage within the container. The GADE machine, containing 4kg of sawdust, totally decomposed 59.75 kg of garbage within 3 months (0.66 kg/day). Constant temperature, pH level, and moisture content of the matrix throughout the experimental period suggested stable degrading action. The residual sawdust and drainage water from the GADE machine were converted to fertilizers or soil conditioners (GADE compost) by the garbage decomposition process. Neither inhibited germination or growth of three test crops: komatsuna, Chinese cabbage (Brassica campestris), hatsukadaikon, radish (Raphanus sativus L. var.radicula), and bisai (Raphanus sp.).
