Composting is one of the suitable method for disposal of organic waste and convert it in to organic fertilizer. For effective composting, role of temperature within the composting heap is important. Variation of temperature in the composting heap is the indicator of type of microbial biomass present during the composting. Present study was conducted to find out the minimum volume of waste for effective composting. The present study was conducted in two phases. The first phase of study was conducted to monitor the temperature variation in different volume of composting heap and second phase of study was conducted to study the leachate production in food and vegetable waste. The results of the present study revealed that minimum 80 and 100 kg of food and vegetable waste required maintaining the thermophilic and mesophilic stage. To attain the thermophilic stage the minimum volume should be around 0.5 m3 and minimum height 0.6m. Leachate was produced at initial stage of degradation and it was more in vegetable waste compared to food waste.
堆肥是处理有机废物并将其转化为有机肥料的合适方法之一。对于有效的堆肥来说，堆肥堆内部温度的作用很重要。堆肥堆中温度的变化是堆肥过程中存在的微生物生物量类型的指标。本研究旨在找出有效堆肥所需的最小废物量。本研究分两个阶段进行。研究的第一阶段是监测不同体积堆肥堆中的温度变化，第二阶段是研究食物和蔬菜废物中的渗滤液产生情况。本研究结果表明，至少需要80千克和100千克的食物和蔬菜废物来维持嗜热阶段和中温阶段。要达到嗜热阶段，最小体积应约为0.5立方米，最小高度为0.6米。渗滤液在降解初期产生，与食物废物相比，蔬菜废物中产生的渗滤液更多。
