Quality comparison of two methacomposts comes from animalrearing of laboratory and university restaurant of Oujda university in Morocco

This work focuses on the valorization of organic waste through two treatment processes,anaerobic digestion and composting,allowing for the production a good quality of fertilizer that name is methacompost. the waste examined are animal waste of laboratory in the faculty of science,and household waste of the university restaurant. we compared the behavior of the two organic wastes in the anaerobic and aerobic processes. after these process,we have acquired two good methacomposts taking into account their physico-chemical and microbiological characteristics. the two methacompost products have a ph between 7.5 and 7.7,a minimum salinity of the order of 1.5 ms/cm and a organic composition of 10 % and 30 % respectively for the laboratory waste and restaurant. the pathogenic bacterial load is very low in methacompost from laboratory waste and practically nil in restaurant waste,so the methacomposts have impeccable hygiene. both methacomposts can be used as an organic soil amendment. the methacomposts will be used in the nursery of the university of oujda. © 2017,university of mohammed premier,oujda morocco.
