An international team of researchers has developed a solar PV system that efficiently converts cattle dung into syngas, reducing CO2 emissions and demonstrating a net energy recovery of 40.17%. The system has a payback period of 3.75 years and can generate annual revenue of 98,703 PKR ($352.1) at a processing capacity of 5 kg/day. Gasification at 800 C was found to produce optimal syngas yields and is scalable for larger CAFOs. The study highlights the importance of system utilization, operational factors, and maintenance in determining the overall feasibility of biomass energy systems. Further research will focus on scaling up the system, optimizing syngas yield, and evaluating its performance in different environmental conditions.
