Green Practices Guideline for Livestock Sector

CASE STUDIES GENERATION OF BIOGAS FROM LIVESTOCK DESCRIPTION: This study focuses on the implementation of biogas plants in animal farms in Malaysia as a waste management system. Biogas plants use animal manure to produce biogas, which can be used as a source of energy for cooking, incineration, and electricity generation. The effluent from the biogas digester is also used as organic fertiliser. The study evaluates the current status of biogas plants based on livestock waste in Malaysia until 2018. RESULTS: Fifteen biogas plants based on livestock waste were developed in Malaysia by 2018. These plants were primarily aimed at domestic use, with seven on cattle farms, four on pig farms, three on poultry farms, and one on a buffalo farm. However, only 40% of the biogas plants were still functional, while 60% were dormant or nonfunctional due to various factors such as poor maintenance, design errors, lack of technical knowledge, improper planning and monitoring, and insufficient livestock waste for continuous biogas production. The construction costs of the biogas plants ranged from MYR4,500 to MYR30 million. CONCLUSION: The adoption of biogas technology in Malaysia’s livestock sector has remained low despite efforts to promote it. The government and relevant stakeholders need to take concerted efforts to encourage farmers to implement biogas systems as a waste management solution. Further studies are being conducted to assess the feasibility and viability of biogas plants for livestock waste treatment. Government support, including incentives and subsidies for farmers, can play a crucial role in promoting the adoption of biogas technology and reducing environmental pollution while increasing farm profits. 56 GREEN PRACTICES GUIDELINE FOR LIVESTOCK SECTOR
