This study aimed to co-compost Chinese medicinal herbal residues (CMHRs) as the bulking agent with food waste (FW) to develop a high value antipathogenic compost. The FW, sawdust (SD) and CMHRs were mixed at three different mixing ratios, 5:5:1, 2:2:1 and 1:1:1 on dry weight basis. Lime at 2.25% was added to the composting mix to buffer the pH during the composting. A control without lime addition was also included. The mixtures were composted in 20-L in-vessel composters for 56 days. A maximum of 67.2% organic decomposition was achieved with 1:1:1 mixing ratio within 8 weeks. The seed germination index was 157.2% in 1:1:1 mixing ratio, while other ratios showed <130.0% and the treatment without lime showed 40.3%. Therefore use of CMHRs as the bulking agent to compost food waste at the dry weight ratio of 1:1:1 (FW: SD: CMHRs) was recommended for FW-CMHRs composting.
本研究旨在将中药材废弃物（CMHRs）与食物垃圾（FW）共堆肥，以开发高价值的抗病原堆肥。FW、木屑（SD）和 CMHRs 按干重比分别为 5:5:1、2:2:1 和 1:1:1 的三种不同比例混合。堆肥过程中添加 2.25%的石灰以缓冲 pH 值。还包括一个不加石灰的对照。混合物在 20 升容器堆肥器中堆肥 56 天。在 8 周内，以 1:1:1 的混合比例可实现最大 67.2%的有机分解。在 1:1:1 的混合比例下，种子发芽指数为 157.2%，而其他比例则低于 130.0%，不加石灰的处理则为 40.3%。因此，建议在 FW-CMHRs 堆肥中以干重比 1:1:1（FW:SD:CMHRs）的比例使用 CMHRs 作为堆肥的膨胀剂来堆肥食物垃圾。
