摘要：

Material flow analysis (MFA) is an excellent tool that describes the static situation of different materials flows between different subsystems in a defined system. This study estimated the annual amount of the total waste generation in Minna main abattoir; it calculated abattoir waste flow and employed MFA using the waste cube model to illustrate the flows of abattoir waste from waste generators to waste disposers. Results indicated that a total of 66,630 cows and 13,884 goats were slaughtered in Minna main abattoir. This generated 849.54 tons of blood, 550.39 tons of intestinal content, 814.83 tons of bone and 437.55 tons of waste tissues between 2010 and 2012. The abattoir waste flow indicated that the dominant waste treatment methods of Minna main abattoir was re-use and recycling, accounting for 72.60% of waste disposal on the average from 2010 to 2012, whereas blood accounted for 32.03% of the total abattoir waste for the same period. The study has shown how solid wastes from Minna abattoir can be managed and converted into value-added products for effective utilization. The solid wastes generated can be re-used for land application as manure or recycled for other income generating activities like animal feed and aquaculture.
