Open Coal

Today, solid waste management in coal mines is an urgent requirement for the coal mining industry. The overlying materials removed from a seam of coal are solid wastes transported to dumping sites and should be strictly, efficiently managed and monitored by an automatic system. These wastes must be separated for use as leveling and filling materials or residue materials need to be processed in order to minimize the impact on the environment. The system was designed to manage and monitor vehicles transporting solid waste in open coal mines to force them in tasks of taking solid wastes and giving out these wastes in the right places, to help collect and process suitably. The results showed that the calculation of numbers of trips using the software program named "Management of trucks" achieved the statistics of running trucks between the points of removing wastes and dumping sites, in which the numbers of valid and invalid trips were given out. The monitoring process obtained the statistics of active and inactive total time of vehicles transporting solid waste. From that we can calculate and classify them at each dumping site. In addition, the statistics of productivity of power-shovels, fuel consumption levels of excavators and trucks were also gained. Hiện nay quản lý chất thải rắn tại các mỏ than là một yêu cầu cấp bách đối với ngành khai thác than. Các chất thải khi bóc vỉa được chở đến các bãi đổ cần có một hệ thống quản lý giám sát chặt chẽ. Những chất thải này phải được phân loại để làm vật liệu san lấp hoặc vật liệu cần xử lý nhằm giảm thiểu các tác động tới môi trường. Hệ thống được thiết kế có nhiệm vụ quản lý và giám sát các xe chở chất thải trong quá trình khai thác tại các mỏ lộ thiên, đảm bảo các phương tiện này được xúc và đổ đúng nơi quy định, giúp thu gom, xử lý một cách phù hợp. Kết quả cho thấy rằng việc tính toán số lượng các chuyến xe bằng cách sử dụng chương trình phần mềm có tên là "Quản lý xe tải" thu được các số liệu thống kê xe chạy giữa các điểm xúc chất thải và các điểm đổ, trong đó thống kê được số lượng các chuyến đi hợp lệ và không hợp lệ. Quá trình giám sát thu được các số liệu thống kê của tổng thời gian hoạt động và không hoạt động của các phương tiện vận chuyển chất thải rắn. Từ đó chúng tôi có thể tính toán và phân loại chúng ở mỗi điểm đổ chất thải. Ngoài ra, cũng thu được các số liệu thống kê năng suất hoạt động của máy xúc, mức tiêu thụ nhiên liệu của máy xúc và xe tải.

The Impact

Discharging of untreated municipal solid wastes (MSWs) onto land is very widespread in developing countries. The compounds contained in MSW cause a harmful effect to human and environment. Hence, an assessment of the extent of their local impact is of great interest to figure out the pollution they cause. Therefore, this study aimed at evaluating the effects of discharge of solid wastes on soil quality within the landfill of Ain-El-Hammam municipality (Algeria). To achieve this, different soil physicochemical parameters were considered: granulometry, electrical conductivity, pH, organic matter content, and heavy metal concentration. The results indicated the influence of the MSW on the physicochemical characteristics of the soil by enhancing the organic matter content of soil (4.53%) and increasing heavy metal content (Cu, Zn, Cd, Pb, Ni, and Cr), which is a clear indication of the level of pollution they are generating.

Both natural and anthropogenic coastal landforms characterize Penang Island. As years have passed it is a challenge to differentiate the genuineness of landmasses created by natural geological formations or by coastal reclamation projects. An account is given of the environmental impact of solid wastes used for reclaiming land in coastal areas of Penang and of the impact of a major sewage outfall in the western channel. Leaching of heavy metals was shown to be one of the main sources of contamination from solid wastes. This paper presents eight lines of ground penetrating radar (GPR) surveys and sediment analysis to identify the anthropogenic interventions that shaped the urban landscape of Penang Island by excavations, filling, and embankment construction along the coastline and differentiate it from the natural one. The surveys were implemented in two locations, the Batu Ferringhi area, representing the natural coastline, and Persiaran Bayan Indah (the Queensbay Mall area), representing the anthropogenic coastal landform. The apparent depth of penetration that was achieved using a 250-MHz antenna is limited (less than 5 m). The results show between natural and anthropogenic sediment recorded different radar facies. In complement mode, mean grain size distribution, sorting, skewness, and kurtosis graphics of sediment samples from both sites correspond with the GPR data. This technique can likely be applied to the developing coast, where natural and anthropogenic coastal landform data is incomplete, considering future coastline development.

The Impact

Environmental impacts and attendant nuisance of solid wastes escalate in the 21st Century. Effective management of the wastes in a holistic manner is a proven way out of the menace. This research focuses on accessing the life cycle of solid wastes in Osogbo. The main objective is to evaluate the physical and chemical constituents of the wastes and determine their best disposal method in the study area. In the study, wastes were collected over a period of 2 weeks, wastes composition was determined for the randomly selected residential buildings, and the per capital waste generation rate was evaluated for the area. Potable gas detectors were used to detect and measure the gases present at this dumpsite. The emission of gases and energy consumption was evaluated using the methodology of life cycle in calculating life cycle inventory of the waste strategies. The measured gases include; Sulphur (IV) oxide (SO2), carbon monoxide (CO), carbon (iv) oxide (CO2), ammonia (NH4). The Tool for the Reduction and Assessment of Chemical and other Environmental Impacts (TRACI) of the United States Environmental Protection Agency and the Methodology of the Centre for Environmental Studies (CML) of the University of Leiden are the two approaches applied as provided for in the GaBi6 (Holistic Balancing) Life Cycle Assessment (LCA) software database, to classify and characterize environmental impacts of municipal wastes in Osogbo. The Impact Indices measured from both scenarios were: Global Warming Potential (GWP), Acidification Potential (AP), Eutrophication Potential (EP) and Ozone Layer Depletion Potential (ODP). For the Life Cycle Impact Assessment (LCIA), two waste management scenarios were developed and compared using GaBi6 software. Scenario one involves collection, transportation and incineration, while Scenario 2 ends with landfilling. Findings showed that the overall mean percent (%) wastes composition for paper, biodegradable, plastic, glass, metal, wood and textile were respectively found to be 4.32, 67.53, 5.07, 4.90, 6.54, 8.74 and 2.90. The per capita waste generation in the study area was found to be 1.09 kg/capita/day. From the results of LCIA methods studied using the ODP index, Scenario one with the TRACI method gives the total values for GWP, AP, EP, ODP as 4.18, 1.08, 1.392E-4, 3.147E-8 respectively. With the CML method, the values are 4.18, 1.3E-3, 3.771E-4, 2.878E-8 respectively. The respective results from scenario two with the TRACI method and CML methods showed total values for GWP, AP, EP, ODP as 9.64, 0.112, 3.108E-3, 1.447E-11 and 9.64, 1.77E-3, 7.247E-3, 1.361E-11. It is concluded that of the two management scenarios considered, landfilling of wastes is more environmentally friendly as compared to incineration, and is therefore recommended for use in the study area.

The Impact

Disposal of municipal solid wastes (MSW) remains a challenge to minimize its impacts on the environment and human health. Landfilling, currently the most common method used for MSW disposal, occupies land space and leads to soil and air emissions. Gasification, an alternative MSW disposal method, can convert waste to energy, but can also lead to soil and air emissions and is a more extensive operation. In this study, life cycle assessments (LCA) of the two disposal methods (landfilling without energy recovery and gasification) were compared to understand impacts on environment and health. The LCA was conducted following the ISO 14040 standards with one ton of MSW as the functional unit. The life cycle inventory was obtained from published journals, technical reports, LandGEM, HELP and GREET database. The impact assessment was done using TRACI 2.1 and categorized into eight groups. The LCA revealed that landfilling is a higher contributor in global warming, acidification, smog formation, eutrophication, ecotoxicity and human health cancer and non-cancer categories. The negative environmental impacts of MSW landfilling can be primarily attributed to the fate of leachate loss and landfill gas, while those of the MSW gasification can be attributed to the disposal of its solid residues.

The Impact

The problems of solid waste in Ilorin East Local Government Area (LGA) of Kwara State are uncontrolled dumping of wastes in the environment, lack of standard landfill and poorly located dumpsites. In this paper, the life-cycle of solid wastes in Horin East Local Government Area of Kwara State was examined using GaBi, modeling tool and the implications of their environmental impacts were identified. Three major dumpsites viz: Apado, Agbeyangi, and Oke-Oyi were selected and the concentration levels of CH, CO, SO, and CO gases were measured using ToxiRae gas sampler. Two waste management scenarios were developed and compared using GaBi,software version. Scenario 1 involved collection, transportation and landfilling, while Scenario 2 involved collection, transportation, and incineration. The impact indices determined for both scenarios were Global Warming Potential (GWP), Acidification Potential (AP), Eutrophication Potential (EP) and Ozone layer Depletion Potential (ODP) using the Tool for the Reduction and Assessment of Chemical and other Environmental Impacts (TRACI) of the United States Environmental Protection Agency and the Methodology of the Centre for Environmental Studies (CML) of the University of Leiden in the GaBi, software version. The impact indices of landfilling scenario for GWP, AP, EP, and ODP were 2.63(kgCO, Equiv.), 1.50E-03 (kgSO,Equiv.), 3.22E-03(kg Phosphate Equiv.) and 9.98E-12(kg CFC 11-Equiv.), respectively. Those of the impacts of incineration scenario for GWP, AP, EP, and ODP were 3.32(kgCO, Equiv.), 9.20E-04(kgSO,Equiv.), 3.72E-04(kg Phosphate Equiv.) and 2.49E-08(kg CFC 11-Equiv.), respectively. Landfilling of wastes poses a lesser burden on the environment, using ODP index, as compared to incineration and therefore recommended for use in the study area.
