Table 9 shows the potential of methane content of biogas production from the livestock waste measured in different regions of Malaysia. As can be seen, the potential of methane evolved in Peninsular Malaysia, Sabah and Sarawak were estimated as 2333, 149.76 and 279.47 million m3 yr−1, respectively. The results shown in Table 9 also indicated that the methane produced from the animal waste was potentially able to provide the heat energy with the value of 7.15×1010, 4.59×109 and 8.56×109 MJ yr−1 in Peninsular Malaysia, Sabah and Sarawak, respectively when biogas could be burned on-site.
