Abstract：

    The objectives of this project are focused on re-utilization technology of livestock animal manure for planning centralized poultry manure power plants and biogas plants as well as proposes optimal strategies for low carbon emission localized livestock resource re-utilization. Both power plant and biogas plant can make animal manure to electricity, renewable energy (e.g. biogas or bio-methane), and organic fertilizers. Poultry litters are mostly used in farms which centralize at some regions nowadays, therefore, developing regional re-utilization models with low carbon emission is well needed. This research integrates the results of the economic benefit scenario analysis of power generation from poultry litters combust of laying hens or broilers in Taiwan. Investment is worth only if the government subsidizes related equipment or the purchased price for electricity. Moreover, government also needs to revise the regulations about raw material supplication, to make it possible to obtain poultry litters in lower price or for free. This study also compares the greenhouse gases (GHG) emission of different manure management methods: simple fermentation (A), compost turned with bucket loader (B), and compost with automatic turner (C). Results showed that the manure form method C was well-fermented with lowest GHG emission. Although method C produces some GHG from automatic turner, method C is the prior manure management method applied if the mechanical electricity cost could be reduced.
