Wastes in abattoir environment have been a great concern to public health authorities in Nigeria. The objective of this study is to integrate the management of abattoir wastewater into the composting technique at Alesinloye market waste recycling complex, Ibadan. The study design was exploratory with laboratory analysis. Direct measurement with specified tools and observation checklist were used to obtain information on composting procedures in the complex. Two experimental windrows were set up for composting. Both compost piles contained mixed organic waste (MOW) and cow intestinal waste (CIW). The first pile was moistened with abattoir wastewater (AWW) while the second pile was moistened with ordinary water (OW). At the end of maturation, organic-carbon, total nitrogen, C:N ratio, total phosphorus, magnesium, potassium, iron, sulphur, lead, chromium, nickel, zinc, and cadmium contents of the MOW, CIW, AWW and OW were determined, according to the American Public Health Association (APHA, 1992). All the chemical nutrients, except carbon (C), Mg and S, were found with highest values in wastewater. The study showed that abattoir wastewater could be used to improve the nutritive quality of compost produced at the complex and thereby reduce its environmental and public health problems.
