The potential of different bio-decomposer for composting of food waste and rice husk

Abstract

Abstract The research was conducted to compare the effectiveness of bio-decomposers using food waste, rice husk and black organic soil at the ratio of 2:1:1. In landfill the food waste is commonly segregate for composting. Longer decomposition times and inefficient composting approaches leads to poorer compost quality. The primary objective was to determine the physical and chemical characteristics of bio-decomposers in various compost treatments. Data analysis shows, all the bins are within the USDA's recommended range for composting. But then, bin C were most effective that possesses the following values: pH of 7.1, temperature at thermophilic stage was 46.3 °C, temperature at maturation stage was 38.0 °C, moisture content of 39.25 %, C/N ratio of 31.16 %, 2.09 % of nitrogen (N), 2.60 mg/l of phosphorus (P), and 3.68 mg/l of potassium (K). Subsequently, the second aim to measure on the growth rate of the Amaranth seed in different bins after composting. As per analysis, the Amaranth plant height was increases B at 6.95 cm, C at 7.32 cm. The number of leaves counted over a period of 30 days reveals that three bins, A, B, and C, each had 7 leaves, while bin BL at 6 numbers of leaves. In summary, bin C optimal parameters ranges shows the most effective bio-decomposer.
