Studies on the Improvement of an Electric Garbage Processor----Base Materials for an Electric Garbage Processor which Facilitates a Microbiological Degradation----
Minoru Takemoto*, Yoshiko Tsukamoto** and Shunrokuro Fujiwara*Abstract
Wood chips are used as the base material for many marketed commercially garbage processors currently. However, the composting of wood chips requires a long time, because they require a long time for degradation. Therefore, in order find a new base material, the suitability of 23 kinds of materials was examined. The test substances were mainly agricaltural materials. As a result, we were able to classify the characteristics of materials to be used as the base material for many types of garbage processors.
4 kinds of materials(bark compost, crushed coconut shell(Berabon), vermiculite and a moisture absorbent additive) were mixed. 16 mixtures were made from these materials and the suitability of these mixtures as base materials for an electric garbage processor was examined.
Data were measured of 3 stages(early, middle, latter term)of this investigation and analyzed. The results show that the bark compost controlled the pH and decreased the emission of ammonium gas, while crushed coconut shell maintained the stirring efficiency throughout all stages of the decomposition. It was shown that vermiculite increased the emission of ammonium gas and decreased the stirring efficiency. The moisture absorbent appeared to affect these factors, but this effect was limited to the middle stage.
In conclusion, it was shown that a mixture of bark compost and crushed coconut shell is an efficacious base material for electric garbage processors. As a result of further investigation into the ratio of bark compost and crushed coconut shell, it was shown that mixtures consisting of 1/4 or more bark compost and 1/4 or more crushed coconut shell were suitable as base materials for electric garbage processors.
