“…Krexner, et al [18] on the other hand deduced that biogas generation attributing to manure management only contributed to 10.07 % of GWP with respect to the cradle-to-gate system boundary of his study inclusive of manure acquisition up to synthesis of product. Nonetheless, chicken manure can also be treated through other waste-towealth approaches such as composting, pyrolysis, and gasification [19].…”

Abstract. Fossil fuels are the primary reservoir of Malaysia’s energy supply hence, the government and major stakeholders are looking into renewable means for energy generation. Chicken manure on the other hand is an abundant biomass waste as chicken is the second most staple food item in the country after rice. Thus, green energy generation via anaerobic digestion of chicken manure is an option. The motivation behind this research is to dismiss claims that green energy generation is more detrimental to the environment compared to the conventional fossil fuel driven approach. A Life Cycle Analysis comprising of Life Cycle Inventory and Life Cycle Impact Assessment was conducted using Microsoft Excel to evaluate the environmental constraints of energy generation via anaerobic digestion specifically in the global warming, eutrophication, and acidification potential impact categories. The findings revealed that the global warming potential is up to 832248.183 kg CO2 equivalents (eq), outweighing the concern of the other two impact categories. This is because carbon dioxide is the main greenhouse gas emitted during the process primarily due to poor management of chicken manure at the broiler house. Thus, recommendations were put forth in terms of introducing other practices parallel to anaerobic digestion such as composting and gasification which also yield value added products.

“…The removal of ammonia from CM wastewater using air stripping by varying initial pH (7,9,11), temperatures (30 °C, 50 °C, 70 °C, 80 °C, 90 °C) and air flow rates (0.5 and 4 L min -1 ) removed 80 % of ammonia at the optimum operating parameters of pH, temperature, and flow rate of 11, 80 °C, and 4 L min -1 , respectively, during pre-anaerobic digestion as indicated in Fig. 1.…”

“…It has been noticed that 1 t of waste rich in organic matter can produce 847 kWh of electricity and 87.98 GJ of heat. The rise in the consumption of chicken meat has increased the production of chicken farms globally which -----resulted in higher amounts of chicken manure (CM) [7]. CM contains nitrogen, phosphorous, and proteins and can be used as a natural fertilizer for growth of crops.…”

Control Strategies for Enhanced Biogas Production from Chicken Manure

The control strategies adopted in formulation and anaerobic digestion (AD) process of chicken manure (CM) for the control and enhancement of biogas production are reviewed. The existing limitations and future challenges in the production of biogas from AD of CM are briefly discussed. The control strategy adopted for formulation is pretreatment of CM (physical, chemical, biological, and thermal) while strategies for AD include selection of optimal parameters (pH, C/N ratio, organic loading rate (OLR), and temperature), co‐AD with other substrates, and addition of supporting materials. The pretreatment of CM, selection of optimal parameters, Co‐AD of CM with other substrates, and addition of supporting materials overall enhance biogas and methane production due to increase of hydrolysis and C/N and decrease of ammonia inhibition, CO2 and H2S contents. The implementation of developed control strategies in continuous plants, development of new strategies, and use of supporting materials in combinations of two or three for better performance are the future challenges in the AD of CM. The control strategies had a significant impact on the efficient use of CM and improved biogas and methane production.
