Abstract
This study presents the daily generation of municipal solid waste (MSW), the methane (CH4) generation rate constant (k value) based on the composition and characteristic of MSW and the current collection practices of MSW in the three zones of Mogadishu City, Somalia through survey. The MSW samples were collected from three (3) sampling zones (Zones 1, 2, and 3; 204 households) and weighted (kg), the waste generation per person per day was estimated. The MSW characterization includes sorting (based on plastic/polythene, food wastes, wood, metals, yard waste, paper/cardboard, textile, glass/ceramic and miscellaneous components, %), the determination of bulk density (kg/L), and measuring moisture content (%). The k values were evaluated from the
percentages of different components in MSW based on first-order decay models. Mogadishu city generated 1671.03 kg MSW per week (maximum on Friday: 348.72 kg, and minimum on Monday: 152.04 kg). The total mean MSW generation rate observed in this study was 0.2 kg/person/day. The solid waste generation found was in the decreasing order of food waste > plastic/polythene > yard waste > miscellaneous > papers/carboard > wood > glass/ceramic > textiles > metals by weight. The average bulk density was found to be 0.269 kg/L. The average moisture content was ranged from 61.6 to 73%. The total k values were categorized as fast (Zone 1: 0.216053 yr−1, Zone 2: 0.228739 yr−1, and Zone 3: 0.244595 yr−1) and moderate (Zone 3: 0.244595 yr−1) degradation. The current collection practices of this study show the majority respondents' practices were found by 400 (80.0%) did not use waste storage and 100 (20.0%) of those used waste storage. Most of the majority of the respondents 421 (82.2.%) used sacks for collecting wastes in their homes, while very few of the respondents 52 (10.4%) used plastic for collection of wastes and 14(0.6%) used baskets for solid waste collections, while 5(1.0%) used barrels to collect waste and the very least respondents 3 (1.8%) used bags for storage of wastes in their houses. This study can be used for research reasons by local authorities, research institutes, and universities. It will also provide Somalia with basic data on all aspects of environmental policy and challenges on SWM current collection practices for all national solid waste management policy. This research contributes baseline data for solid waste management (SWM), which will support the development of sustainable municipal solid waste (MSW) in Mogadishu city, Somalia.
