This study utilized three different compost production methods, the conventional aerated system (CAS), the anaerobic barrel system (ABS), and the rapid-disposal machine (RDM), and observed the related mung bean germination rates, which are indicators that assess the maturity and quality of compost. All three production methods used the same kitchen waste, and reached maturity after 24 days, 60 days and 5 days, respectively. Mung beans were then seeded to test their germination rates. The results showed that by the fifth day, RDM had the best germination rate, followed by the CAS and ABS. However, the former method had a poor root growth, while the other two had ideal situation root growth conditions. After another five days passed, the roots of the beans grown in the RDM compost started to turn black. At the seventh day, the RDM beans all decomposed. However, the young roots of the beans grown in CAS and ABS compost did not suffer in this way.
