| Summary: | Biowaste management is a pertinent problem and nutrient recycling utilizing fly larvae
is an emerging solution. The leachate produced during biowaste management has potential
implications for the environment but studies on this issue are scanty. This study was conducted
to assess the characteristics of leachate produced during the bioconversion of food (BW-I) and
poultry slaughter waste (BW-II) by natural fly larval activity. The results showed that total volumes
of 2.2 L and 1.1 L leachate were produced for BW-I and II respectively. The highest pH in BW-I
leachate was 7.43 ± 0.01 and the lowest pH in BW-II was 3.30 ± 0.12. The highest levels of BOD in
BW-I and II were 36733.33 ± 430.63 mg/l and 2800.000 ± 999.50 mg/l. The highest level of COD
in BW-I was 52575.000 ± 1076.86mg/l while in BW-II it was 4316.67 ± 790.45 mg/l. The high BOD
and COD values of the leachate indicated that they needed to be pretreated before being released
into the environment. |
