Open dumping of municipal solid waste is a common practice in developing countries including Ghana and it creates major problems many municipalities towns the countries, therefore, dumpsites need to be reclaimed or decommissioned after years dumping. However, becomes challenging infer from results studies other part world for since they may have different characteristics. Therefore, this study sought characterize dumpsite with age groups urban city small town ascertain impacts aging deposited on fractions, also assessed components at depths within same both small-town dumpsites; more than 5 (Zone A), 2–4 B), less 6 months C) Bono region, Ghana. Waste (100 kg) was taken surface, 0.5 m, 1.0 m 1.5 reduced 50 kg using coning quartering method; dried, segregated analyzed. Plastics (24.5–28.1%) increased urban, (5.4–8.5%) depth dumpsite. Plastic second Decomposed organic matter (DOM) dumpsites. The metal (<1.0%) all sites. DOM fine particle sizes (FPS) decreased depth, 26.8% (surface waste) 14.4% (1.5 depth), Statistically significant effects plastics, metal, DOM-CPS, DOM-FPS (p < 0.05) dumpsite, effect statistically only DOM-CPS 0.05). pH, EC, TDS increasing age, depth. provides relevant scientific findings stakeholders develop policy framework decommissioning reclamation.
