In the present study, fly ash was used as an additive for the rapid composting of biomass and kitchen waste with jaggery as an activator. The in-vessel composting experiments were carried out in ten plastic vessels of 15 L capacity containing varying amounts of fly ash, biomass waste, and kitchen waste. The effect of fly ash on the microbial and enzymatic activity of the composting system was also ascertained. The compost in Vessel No. 10 having a combination of 50% biomass waste, 30% kitchen waste, and 20% fly ash seemed to have a significant effect on the compost quality. Statistical analysis revealed Vessel No. 10 as significantly separated from other vessels whereas microbial activity (342.67 CFU 10/g), pH (8.15), temperature (48.50 °C), and heavy metals, such as Ni (0.1239 mg kg), Ba (0.6109 mg kg), Cd (0.0004 mg kg) were the most influential variables for the separation.
在本研究中，粉煤灰被用作生物质和厨余垃圾快速堆肥的添加剂，糖蜜作为激活剂。在十个 15 升容量的塑料容器中进行了容器内堆肥实验，每个容器中含有不同量的粉煤灰、生物质废物和厨余垃圾。还确定了粉煤灰对堆肥系统微生物和酶活性的影响。在第 10 号容器中，生物质废物、厨余垃圾和粉煤灰的组合为 50%、30%和 20%，似乎对堆肥质量有显著影响。统计分析显示，第 10 号容器与其他容器明显分离，而微生物活性（342.67 CFU 10/g）、pH 值（8.15）、温度（48.50°C）和重金属，如镍（0.1239 mg kg）、钡（0.6109 mg kg）和镉（0.0004 mg kg）是分离的最主要影响因素。
