ABSTRACT
Studies on municipal solid waste (MSW) generation, disposal
and management over seasons (rainy and dry season) in 2004 were carried out in
Umuahia and Aba, Abia - - State, Nigeria. In each cities, well-structured
questionnaires were used to assess the current status of waste generation and
disposal as well as the factors militating against proper waste disposal
practices. A 3 x 14 factorial experiment in a randomized complete block design
(RCBD) with three replicates was used to determine the quantities and types of
waste generated and disposed over seasons at Abia State Environmental
Protection Agency's waste disposal sites in Umuahia and Aba. The first factor
comprised three study sites selected in each city, namely; urban market, urban
residential area and World Bank Housing Estate. The second factor consisted of
fourteen (14) waste types. Sample of soils at the landfill dumpsites and nearby
bush fallow sites in the study locations were also collected and analysed for
physico-chemical properties. A single factorial experiment in randomized
complete block design with three replications was also used to determine the
nutrient contents of fresh 4- • biodegradable wastes at the dumpsites. The
percentages of waste types generated in Umuahia and Aba, by respondents to
questionnaires were as follows: kitchen waste — Umuahia (40%) and Aba (15%);
condemned papers and stationeries — Umuahia (22%), Aba (15°i); polyethylene
materials such as bags, water proof, water sachets — Umuahia (20%), and Aba
(25%). The patterns of waste disposal (% by respondents) were as follows: open
dumpsite — Umuahia (45%) and Aba (30%); into rivers/streams —Umuahia (3%) and
Aba (12%); along the streams Umuahia (30%), and Aba (24%), into gutters / 0 -
drainage's — Umuahia (12%), and Aba (18%). Some factors militating against
proper municipal waste disposal were as follows (% of respondents): poor
funding — Umuahia (45%) and Aba (50%); inadequate infrastructures such as waste
receptacles, disposal tiucks — Umuahia (20%) and Aba (35%); inadequate ASEPA
personnel 101 paper waste disposal and management — Umuahia (8%) and Aba (4%);
inadequate refuse dumpsites — Umuahia (15%) and Aba.( (25%) Using children for
waste disposal — Umuahia (47%) and Aba (40%); vegetable wastes gave
significantly the highest quantity of municipal solid waste types generated
daily during the rainy and dry seasons at Umuahia (12.04t day 1 — rainy season,
7.36 t day 1 — dry season) and Aba (3.56 t day 1 — rainy season, 2.29 t day 1 —
dry season). Aluminum materials, polyethylene and rubber materials had the
least mean daily waste quantities over seasons at Umuahia (0.15 t day 1, 0.43 t
day 1, 0.62 t day 1 respectively) and at Aba (0.12 t day 1, 0.44 t day, 0.38 t
day 1 respectively). No significant differences existed between the results of
the quantities of wastes generated and disposed at Umuahia and Aba. The
municipal waste dumpsites at Umuahia and Aba had loam sand soil textures. The
soil texture of the bush fallow site at Umuahia and Aba were respectively sandy
soil and sandy loam. The pH values of the dumpsite (6.81) and bush fallow
(6.08) at Umuahia were similar. At Aba, the pH of the waste dumpsite (5.70) was
significantly higher than that of the bush fallow site (7.65). Umuahia had a
C:N ratio of 12.00 and 8.60 at the dump and bush fallow sites respectively. The
C:N ratios at the dumpsite and at the bush fallow site at Aba were 4.98 and
5.53 respectively. The GEC and percentage base saturation of the dumpsite
(74.37%) and nearby bush fallow site (75.36°i) were similar. Vegetable wastes
gave significantly the highest N content (4.38%), fruit wastes the highest K
and Na contents and vegetable + fruit wastes, the highest Mg contents (0.73%).
The biodegradable municipal waste types had similar P and Ca contents.
