초록
Cattle manure is a good candidate as a solid fuel. But its heat value is relatively low. Urban waste, such as leaves, coffee sludge, and fruit skin, are being produced increasingly and they require cost and labor for collection and processing. This study evaluated ways to improve the lower heat value of cattle manure-based solid fuel by utilizing urban waste. Among the many type of urban waste, coffee sludge, fallen leaves, and tangerine skin were chosen. Various samples were prepared by mixing cattle manure and urban waste at a ratio of 5:5, and their heating value was analyzed at the Korea Chemical Convergence Research Institute. The results demonstrated that all samples had a heating value higher than 3,000 kcal/kg. Therefore, a mixture of urban waste and cattle manure can be a new renewable energy resource.
