ABSTRACT
The organic household waste
fraction originating from Umuahia metropolis was analyzed with respect to
visible contaminations, degradation and chemical composition including heavy
metals, using samples from 2 tonnes of material. After manual sorting and
magnetic separation of the waste, another 20% of wet weight was observed as
impurities and 80% as inorganic solid wastes. Of these, plastics constituted
75.5% and metals 13.6% of wet weight. Where 80% sorted as organic solid waste,
was evaluated, 8% was observed as paper waste and 92% was noted as pure organic
waste materials. The wastes were dehydrated using diastic microbes obtained
from the snail (Achatina fuilca.). Cellulose constituted 169-130g kg-1
DM, crude fat 179-1 20g kg-1 DM, starch 160 — big kg-1 DM,
lignin 113-80g kg' DM, hemicelluloses 56 — 6g kg-1 DM and sugar 22 —
49g kg-1 DM; while the energy value was 14.24 — 10.28 MJ kg-1DM.
The concentrations of cadmium and mercury found in the sorted waste were low (P<0.05) among the treatments, similar data were obtained on molybdenum and other metals and nutrients studied. ><0.05)
among the treatments, similar data were obtained on molybdenum and other metals
