Figure 26. Pie chart-separate organic waste from others

The idea behind this question is to check whether the people in the study area understand the environmental usefulness of organic waste and the implication of mixing it with other categories in the waste stream. It turned out to be my thesis supervisor’s brilliant suggestion to include it in the questionnaire survey. Interestingly, 87.5% of n affirmed that it is essential to have another waste bin for the storing of organic waste, which is displayed with the larger portion of the pie chart above. In fact, a particular respondent in Alimosho LCDA said he ensures that food waste generated at home is kept in a separate waste bin because of the foul odour associated with it when it is mixed with other types of waste, and more importantly that it is useful as manure. Comparison of results from the 6 LCDAs indicate a range of 78% minimum and 93% maximum in favour of yes. In Oke-Odo/Agbado LCDA, 28 out of the entire 29 valid respondents answered yes to show their strong understanding of the need to separate organic waste from

48 others. LAWMA’s specification or expectation of one waste bin per household for all categories of waste therefore contradicts the understanding of the majority to have a separate waste bin for organic waste as far as this research as shown.
