Impact Of Composting On The Physical Factors Of Municipal Solid Waste Materials With Organic Additives In Ihiala Anambra State

ABSTRACT

Nowadays, solid waste disposal is the most pressing problem facing mankind throughout the world and its management is presently an issue of global concern. The present study was designed to evaluate the impact of composting on the physical factors of compost from Municipal solid waste with organic additives in Ihiala local Government Area, Anambra State, Nigeria. Effective microorganisms (bacteria and yeast strains) isolated from plant root, soil and fruit samples were employed in the biosynthesis of nanocomposites. The nanocomposites and effective microbes were further developed and used in the biocomposting and biodegradation of 5.5 kg shredded and dried final waste mixture of approximately 55 % food waste, 15 % saw dust waste, grass chopping waste 22 % and 8 % paper with or without inoculation (control) for 56 days or 8 weeks. The feedstocks and end products of humus like compost were characterized and analysed for physical characteristics like texture, colour, odour, compactness (height), temperature, conductivity and moisture content using standard procedures.The final compost was found to be fine and homogenous in texture, dark brown to black in colour, slightly foul to earthy smell in odour. There were decrease in mass, temperature, conductivity (EC) and moisture content, respectively. Statistical significant differences (P < 0.05) were found only in the conductivity parameters only among the means of treatment set ups relative to control set up. Thus, it could be concluded that the quality of compost of this present study is good and consortium of effective microbes and magnesium nanocomposite is said to be the suitable agent for biocomposting and biodegradation of solid wastes materials.
