| Summary: | The aim of this research was to evaluate the environmental impact from broiler chicken farming industry in Malaysia. In order to achieve that, Life Cycle Assessment method was chosen as a guideline to complete the task. A case study was conducted at a broiler chicken farm to gather the data and information related to the broiler chicken production. Cradle-to-gate assessment including distribution stage was conducted based on the ISO 14040/14044 guidelines. Inventory data for this case study was gathered in collaboration with one of the selected case study broiler chicken farm company. Greenhouse gas emission that consists of several most affected gases such as carbon dioxide, methane and nitrous oxide were studied. Emission to water, soil and overall wastes also included to determine their environmental impact. Result shows that the highest carbon dioxide emission came from manure which accounted for 1,665,342 kg CO2 equivalent per total broilers while the highest methane emission came from feed which accounted for 126,207.84 g CH4 equivalent per total broilers. For nitrous oxide emission, the highest values came from bedding which accounted for 20,316.87 g N2O equivalent per total broilers in the commercial modern broiler chicken farm. For emission to water, results shows that sulfate gives the highest amount which is 8mg/L followed by chemical oxygen demand of 5mg/L, sodium 1mg/L and suspended solid 0.5mg/L. For emission to soil, results shows nitrate gives the highest amount followed by potassium and phosphorus with amount of 0.044, 0.021, 0.019 kg/broiler respectively. For the overall wastes, results shows manure gives the highest amount followed by dead broilers, industrial waste and sludge with amount of 120, 78, 70, 5kg respectively. In this case study, it can be concluded that manure gives the most prominent effect to the greenhouse gas emission followed by feed and bedding materials. It also can be concluded that sulfate gives the most prominent to emission of water, nitrate to emission of soil and weight of manure is the highest for overall wastes. This research study is limited from cradle to gate only. Hence, the other data outside gate are not considered such as the production of feed materials. This study provides conceptual framework to reduce significant impact of environmental problems specifically in modern broiler chicken farming operation. The conceptual framework was validated by identifying the actions taken inside the coop were following the general broiler chicken guideline in Malaysia |
