This study compared the products of pyrolysis of cow dung and poultry litter. A pyrolysis assembly was used to pyrolyze samples of each residue at 450°C for 30 minutes. The main products collected were char, tar oil/pyroligneous acid, and pyrogas. For cow dung, the yields were 42% char, 35.66% tar oil, and 17.34% pyrogas. For poultry litter, the yields were 47.33% char, 28.33% tar oil, and 24.34% pyrogas. Analysis showed the pyrogas from cow dung contained 56.67% methane and 54.33% propane, while p
