The continuous increase in livestock waste has led to increasing environmental pollution and problem of flies, especially to residents living in the vicinity. Application of biogas technology has been considered to be an effective approach in livestock waste management that can mitigate those problems. The use of this technology, in return, can bring economic benefits to farmers in terms of cooking gas and electricity supply. This study elucidates the development stage of biogas plants in livestock sector throughout Malaysia. In 2018, fifteen biogas plants were developed in Malaysia: seven plants built on cattle farms, four on pig farms, three on poultry farms and one on a buffalo farm. However, only 40% of the plants were found still functioning and another 60% were non-functional due to several technical factors like poor maintenance, design and construction errors, improper planning and monitoring as well as lack of technical knowledge to run the system consistently.
