چکیده
Background and Aims: Slaughterhouse waste contains putrescible intestinal wastes as well as organic solids with high levels of pathogenic microorganisms. The management of these wastes is therefore necessary to succeed in preventing the spread of infectious agents. This study set out with the aim of assessing the static aerated pile and agitated aerated pile in the composting of industrial slaughterhouse wastes.Materials and Methods: At every stage of this research, basic parameters such as Carbon: Nitrogen ratio (C:N), were measured. The influence of carbon-to-nitrogen (C:N) ratio, phosphorus (P) and potassium (K) concentrations, pH, electrical conductivity (EC), Ash content, and temperature in the composting pile was studied.
Results: On the question of studied variables, this study found that static aerated pile achieved a C: N ratio of 15.59, P 3.16%, K 2.16%, pH 7.08, EC 1586 μS/cm, and Ash content of 16.88% by weight. The corresponding values in the case of agitated aerated pile were respectively as 18.68, 3.02%, 2.35%, 7.2, 1423 μS/cm and 20.78%.
Conclusion: In general, it seems that both static aerated pile and agitated aerated pile well performed in composting and stabilization of slaughterhouse solid wastes. Both processes produced suitably qualified
compost as well.
