In previous years, practice hand grenades were composed of non-degradable plastics and caused environmental pollution. Therefore, this study applied PLA(Polylactic acid) to practice hand grenades that would biodegradable within a short time. High expectations are being placed on PLA as a substitute for plastics because it can decompose to water and carbon dioxide. The aim of this study was to confirm that the PLA material of a practice hand grenade has biodegradability in a pilot-scale composting unit and estimate the applicability for other items. A composting test was progressed according to ISO 16929(2013). The test process was found to be valid. At the end of the composting test (after 12 weeks), the entire content of the test bin with the test sheet was sieved, sorted and analyzed. A disintegration percentage of 99.2% was obtained after 12 weeks of composting. Therefore, the 90% pass level required by ISO 17088(2013), EN 13432(2000), and ASTM D 6400-12 was easily reached. On the other hand, more research will be needed to determine additional applications of PLA material for consumables.
