The study investigates the characteristics and environmental implications of coal fines at Hwange Colliery Company in Zimbabwe, aiming to address gaps understanding propose sustainable management strategies. research encompasses a comprehensive analysis, including particle size distribution, proximate properties, elemental composition fines, water soil quality analysis. Sample collection analysis were conducted following standardized procedures, revealing significant variations among sites terms distribution properties. sieve revealed that around 80 % passed through 2 mm sieve. Sites A B exhibited lower moisture content higher carbon contrast site C, possibly due variances disposal duration. With an average gross calorific value 17.43 MJ/kg, showcase notable potential for energy extraction. Elemental uncovered traces heavy metals like Fe, Co, Cr, Ni, Cu, posing risk if not managed appropriately. generally low turbidity levels groundwater, with readings ranging from 0.34 0.55 NTU. However, elevated sulfate concentrations some samples, averaging 113.67 mg/l, coupled nickel up 0.07 warrant continuous monitoring ensure compliance safety standards. Soil indicated presence near dump sites, lead reaching 52.32 mg/L, 36.17 copper 53.70 impacting enzyme activity agricultural productivity. emphasizes importance improved waste practices utilization strategies mitigate risks enhance resource efficiency mining operations. • was done Zimbabwe. Transportation dust particles may occur as evidenced by results. Trace elements are indicator pollution open dumping fines.

The dwindling availability of agricultural land, caused by factors such as rapid population growth, urban expansion, and soil contamination, has significantly increased the pressure on food production. To address this challenge, cultivating non-food crops contaminated land emerged a promising solution. This approach not only frees up fertile for production but also mitigates human exposure to contaminants. work aimed examine impact contamination with Cd, Pb, Ni, Zn productivity, metal accumulation, tolerance five lignocellulosic crops: switchgrass (Panicum virgatum L.), biomass sorghum (Sorghum bicolor L. Moench), giant reed (Arundo donax African fodder cane (Saccharum spontaneum spp. aegyptiacum Willd. Hackel), miscanthus (Miscanthus × giganteus Greef et Deu.). A two-year pot experiment was conducted in Greece, Italy, Portugal, following same protocols applying various levels metals: Cd (0, 4, 8 mg kg−1), Pb 450, 900 Ni 110, 220 kg−1). experimental design completely randomized, three replicates each treatment. results showed that generally maintained their height productivity under stress were adversely affected high concentrations. Giant reduced at higher levels. Miscanthus exhibited resilience experienced reductions highest concentration. Heavy uptake varied among crops, showing uptake, while accumulated most Zn. had accumulation. indices indicated more tolerant lower concentrations, whereas demonstrated stable across heavy metals. Accumulation highlighted effectiveness excelled cluster analysis revealed similar responses between reed, well miscanthus, displaying distinct behavior. Overall, study highlights differential accumulation capacities these indicating potential phytoremediation applications metal-contaminated soils.
