楊紹榮、黃瑞彰。2002。生物分解PP太空包在食用菇類栽培之研究。台南區農業改良場研究彙報40:55~66。

   由國外引進具氧化觸媒機能性的可分解添加劑,委託塑膠加工業產製可藉由日光、溫度及微生物等作用而自然分解的PP太空包,於台南縣新營市進行靈芝栽培評估。初步調查得知:靈芝接種後75天,供試生物分解PP太空包之發霉率較高,較傳統PP太空包平均增加13.3-19%。經過五個月餘後,供試生物分解太空包均尚未裂解,且靈芝子實體之發育和傳統PP太空包栽培者並無顯著差異,惟採收後之靈芝產量略低;採收後靈芝子實體及使用過後之栽培介質之主要元素含量,供試生物分解PP太空包和傳統PP太空包亦無明顯差異。初步評估得知:生物分解PP太空包在靈芝栽培仍是可行的。惟使用後的廢棄生物分解PP太空包經109天堆肥化處理後,生物分解PP太空包的延伸率及斷裂強度從使用前的540%及151.6kg/cm2分別降到7.5%及47.8 kg/cm2,雖然物性有明顯降低現像,惟袋子並未破裂成小碎片或變成粉末,故分解腐爛的效果仍不盡理想,因此採用可較易堆肥化處理的分解新材質或將採收後的廢棄生物分解PP太空包進行曝曬處理仍值得繼續評估。

Study of Biodegradable PP Bags in Mushroom Cultivation

Yang, S. R. and J. C. Huang

Summary

The masterbatches of Degra-Novon, IAD 2025 were incorporated in PP resins to produce biodegradable PP bags for ganoderma culture. The results indicated that the percentage of molding of biodegradable PP bags were 13.3~19% higher compared to regular PP bag,75 days after inoculation. There were no difference in size of fruiting body of ganoderma cultured in biodegradable PP bag, but the yields were lower in biodegradable PP bags compared to regular PP bags. The macro-elements content also were not difference in fruiting body and culture media of used biodegradable PP bags,  respectvely, compared to regular PP bags. Although the physical properties of used biodegradable PP bag has been down to 7.5﹪and 47.8kg/cm2 from 540﹪and 151.6 kg/cm2 in elongation and tensile, respectively,247 days after inoculating and composting, but the degradation of used biodegradable PP bag still did not completely decompose, The formula of masterbatches incorporated in PP resins should be modified in advance study.
