<br/><br/> The effects of nanoparticles (NPs) and laser radiation on biogas and methane production were investigated using a specially designed biogas production system . The different concentration of Co, Ni, Fe and Fe₃ O₄ NPs increased the biogas and methane production . The best results of NPs additives were selected based on the statistical analysis (least significant difference using M - stat) of biogas and methane production, which were 1 mg/L Co NPs, 2 mg/L Ni, 20 mg/L NPs and 20 mg/L Fe₃O₄ magnetic NPs (p0.05)
