Abstract
institutional Research farms was done using five standard methods:
biomethanation; feed recovery from the wastes by washing, sieving and
sterilizing with steam; briquetting of the raw manure into solid fuels;
activating the manure to adsorbent; and processing digester liquor and slurry
into organic fertilizer. The study recovered 390± 45 kg dry matter feed/mT of
the wastes with 9.32% Protein and other nutrients; recorded good yield of
biogas and briquettes that burnt with energy of 65.43 MJ/g; activated carbon
(AC) with good adsorbent property; stabilized sludge and liquor with high
content of plant micro- and macro-nutrients useful as organic fertilizer all
showed hope for sustainable management of piggery wastes.
