Abstract

In Bangladesh, vermicomposting has been a popular environmentally friendly composting technique, primarily at small-scale levels. However, few studies have explored the feasibility of medium to large-scale operations. This study establishes a medium-scale vermicompost fertilizer plant in Kushtia, Bangladesh, processing 30 tons of waste monthly to produce 10 tons of fertilizer. Utilizing cow dung from nearby dairy farms and 0.1 million red worms (Eisenia foetida), the experiment runs for three cycles of 120 days each without indoor environmental controls. Over a year, the worm population quadruples to over 0.4 million. Lab tests confirm the fertilizer's pH level (7.69) and nutrient ratios (e.g., 1.792% nitrogen, 0.5217% phosphorus, and 1.514% potassium). The paper includes a cost-benefit analysis, suggesting the viability of such medium-scale setups for green farming in rural Bangladesh.

Abstract

PRAN, situated in Natore, Bangladesh, operates a sizable fruit processing facility. This facility processes approximately two hundred seasonal foods and fruit varieties, generating substantial organic waste. The overarching goal is to establish an organic food chain for both the national and international markets, thereby contributing to the mitigation of Bangladesh's emerging energy and fertilizer crisis. The vermicomposting method was employed, and the experiment was conducted on a miniature scale over 90 days. A dedicated setup was constructed to yield three metric tons of monthly fertilizer. Upon completion of the experiment, the output fertilizer underwent rigorous testing in the laboratory. The results indicated that the component ratios were well-suited for application in agricultural lands. This research marks a significant step towards sustainable waste management and the development of a valuable resource for the agricultural sector in the region.
