Bottom Line: Statistical analysis showed that lipid and lignin are the most significant predictors of BMP.The model was developed from knowledge that the BMP was related to biomass content of lipid, lignin and protein from manure and plant residues as a percentage of VS with coefficient of determination (R-square) at 0.95.This model was applied to calculate the CH4 yield for a household with 17 fattening pigs in the highlands and lowlands of northern Vietnam.

ABSTRACT
Anaerobic digestion is an efficient and renewable energy technology that can produce biogas from a variety of biomasses such as animal manure, food waste and plant residues. In developing countries this technology is widely used for the production of biogas using local biomasses, but there is little information about the value of these biomasses for energy production. This study was therefore carried out with the objective of estimating the biogas production potential of typical Vietnamese biomasses such as animal manure, slaughterhouse waste and plant residues, and developing a model that relates methane (CH4) production to the chemical characteristics of the biomass. The biochemical methane potential (BMP) and biomass characteristics were measured. Results showed that piglet manure produced the highest CH4 yield of 443 normal litter (NL) CH4 kg(-1) volatile solids (VS) compared to 222 from cows, 177 from sows, 172 from rabbits, 169 from goats and 153 from buffaloes. Methane production from duckweed (Spirodela polyrrhiza) was higher than from lawn grass and water spinach at 340, 220, and 110.6 NL CH4 kg(-1) VS, respectively. The BMP experiment also demonstrated that the CH4 production was inhibited with chicken manure, slaughterhouse waste, cassava residue and shoe-making waste. Statistical analysis showed that lipid and lignin are the most significant predictors of BMP. The model was developed from knowledge that the BMP was related to biomass content of lipid, lignin and protein from manure and plant residues as a percentage of VS with coefficient of determination (R-square) at 0.95. This model was applied to calculate the CH4 yield for a household with 17 fattening pigs in the highlands and lowlands of northern Vietnam.

Mentions: The highest BMP in this study was from piglet manure at 443.6 NL CH4 (kg VS−1), followed by cow, sow, chicken, rabbit, buffalo and sheep manures at 222, 177.7, 173, 172.8, 153, and 150.5 NL CH4 (kg VS−1), respectively (Figure 1). The BMP of dairy cow, buffalo and other cattle measured in this study is higher than those given for the manure categories in the IPCC guideline (IPCC, 2006), which are 130 NL CH4 (kg VS−1) for dairy cow manure, 100 NL CH4 (kg VS−1) for buffalo and 100 NL CH4 (kg VS−1) for other cattle manure. The intergovernmental panel on climate change values of BMP for swine manure are 290 and for rabbit manure 320 NL CH4 (kg VS−1), which is higher than BMP measured in this study. The difference is probably due to differences in composition of diet given as feed to the livestock and indicates that it is necessary to determine BMP value of Vietnamese animal manure categories.
