Bananas is an important staple food and cash crop in Tanzania, which
generates huge waste quantities, currently underutilized and discarded causing
detrimental impact to the environment. However, representsun-tapped bio-resource for
bio-valorization into valuable bio-products. A waste audit case study was conducted for
four common cultivars, Mshare-Kahuti, Mbwailuma (Matoke), Kisukari-Mshare and
Kimalindiat Horticulture Research and Training Institute, Tengeru, Arusha, Tanzania.
Wastes quantities generated annually from one hectare were estimated at 57, 99, 64 and
125 tons/year for Mshare-Kahuti, Mbwailuma (Matoke), Kisukari-Mshare and Kimalindi,
respectively. Methane yield of various wastes fresh fractions of Mshare-Kahuti (for
cooking) and Kisukari-Mshare (for desserts) were investigated in batch anaerobic
bioreactors (BAB). The highest methane yields for Mshare-Kahutiof 0.273 and KisukariMshare
of 0.255m3
CH4/kg of volatile solids (VS) added were recorded from corm and
peels banana waste fractions, respectively. The effect of solid state-fermentation pretreatment
of banana wastes with Pleurotus sapidus (P 969) at 10% (wet wt bases) for 7,
14 and 21 incubation days on the extent of methane yield was also investigated in BAB.
Maximum methane yields for Mshare-Kahuti and Kisukari-Mshare were 0.96and |
