    Energy crisis and environmental pollution problems have drawn attention to increase renewable energy resource utilization and replace fossil fuels worldwide. For several decades, Thailand relies on fossil fuels in electricity generation and so on. The Ministry of Energy, Thailand complied the Development of Energy Plans to Thailand Integrated Energy Blueprint (TIEB) in 2020 for sustainable energy development in addition to overcome environmental problems. This case study shows energy recovery from wastes for self-sustain biogas power plants from chicken meat production. The onsite biogas power plant targets at a capacity of 1.5 MW at 24 h for every workday. The chicken manure can yield a biogas output of 128–134 m<sup>3</sup>/ton with the rate of electricity per biogas at 2.10 kWh/m<sup>3</sup>. Based on the project period for 15 years, the payback period, net present value (NPV), and internal rate of return (IRR) are 8.2 years, about 1,705,000 USD, and 8.86%, respectively. In general, the crucial success factor of biogas power plant installation mainly goes to concrete collaboration among the government and private sectors.

    The results showed that the difference of livestock manures showed differences in nutrients and amount. The composted chicken manures contained the highest nutrients and showed an optimum C/N ratio, in which the value was less than 1/20. Three lettuces (green oak, fillice iceberg, and green cos) were treated by different compost manures and they were a response to the compost manures in a similar trend. The three lettuce types grew after the application of chicken compost manure had higher on plant height, plant width, leaf length, leaf width, leaf number per plant, SPAD unit, root length, and plant fresh weight as well as chemical fertilizer. On the other hand, the three lettuces grown after the application of cow, goat compost manures, and bio-fermented fertilizer had the lowest of plant growth similar to control (without fertilizer). The results suggested that the chicken manure compost is suitable for lettuce production.
