Provisional Evaluation of Composting as Priority Option for Sustainable Waste Management in South-West Nigeria
The management of Municipal Solid Waste (MSW) in Nigeria and most
developing countries has remained a major public health challenge, thus creating the need
for reliable and environmentally-acceptable alternatives. This study focuses on
composting assessment as a viable recovery alternative for MSW in six States of
Southwest Nigeria, namely: Ekiti, Osun, Ondo, Ogun, Oyo, and Lagos. Extensive
literature review has been carried out to understand the waste generation patterns in these
states. Reported literature data has been assessed for sustainability of composting strategy
in terms of organic waste streams, amenable of biotransformation as well as in terms of
return through energy saving and material recovery. A life-cycle framework has been
used to estimate GHG emissions, available nutrients, and potential compost production,
instead of landfill in each region. Results show significant potential compost production
of 895,659-, 255,267-, 153,423-, 117,468-, 113,094- and 112, 397-m3/yr for Lagos, Oyo,
Ogun, Osun, Ondo, and Ekiti, respectively. It has been deduced from the study that
composting would be very beneficial to the economy as its product would boost
agriculture production while reducing the budget spent on fertilizer annually
In situ assessment of degradable carbon effusion for industrial waste water treatment
The need for safe and economical methods for wastewater purification has necessitated this research. Blends of different peels: Potato-, apple- and pineapples-peels (PAP-peels) were impregnated with aqueous solutions of ZnCl2 following the variant of the incipient wetness method for activation of activated carbon (AC). Scanning Electron Microscope with attached energy dispersive spectrometer, Atomic Adsorption Spectrometry and Fourier Transform Infrared spectrometer equipment were used for the characterization of the AC produced. The result shows that PAP-peels derived ACs had micro porous characteristics. The study revealed that these new combined adsorbents materials are inexpensive, easily available and they have applications for the removal of Cu, Pb and Cr contained in industrial effluents
