After the airport is put into operation, a large amount of wastes generated every day will bring waste disposal pressure and ecological environment pressure to the airport and surrounding areas. This article expounds the current methods of airport waste disposal. According to the principle of waste reduction, harmless and reclamation, a set of solid waste gasification methods suitable for airports are proposed, which can reduce waste transportation and landfill costs, effectively control the impact of environmental pollution. At the same time, it can use waste heat to generate electricity to turn wastes into treasure and promote green airport construction.

ABSTRAKKota Cimahi merupakan salah satu kota di Jawa Barat yang masih menghadapi permasalahan persampahan, seperti terbatasnya penerapan kegiatan pemilahan sampah, terbatasnya jumlah Tempat Penampungan Sementara (TPS), terjadi pembuangan sampah secara sembarangan ke sungai, terdapat penanganan sampah dengan cara dibakar dan ditimbun, dan lain-lain. Dalam menindaklanjuti berbagai permasalahan sampah tersebut serta mencapai target 30% pengurangan sampah yang ditentukan oleh Kebijakan Strategis Nasional (Jakstranas), maka diperlukan suatu instrumen yang mampu menganalisis area berisiko berdasarkan tingkat risiko persampahan per kelurahan di Kota Cimahi. Area berisiko tersebut digambarkan dalam bentuk peta dengan mengacu pada pedoman Strategi Sanitasi Kabupanen/Kota (SSK) 2018. Area berisiko dinilai melalui skor 1 s.d. 4 secara berturut-turut untuk risiko sangat rendah, rendah, tinggi, dan sangat tinggi. Skor tersebut diperoleh dengan mengalikan parameter Impact dan parameter Exposure. Hasil penelitian ini menunjukkan terdapat tiga kelurahan dengan risiko persampahan sangat tinggi, yaitu Kelurahan Cibeureum, Setiamanah, dan Padasuka serta satu kelurahan dengan risiko persampahan tinggi, yaitu Kelurahan Melong. Penambahan jumlah unit pengolahan direkomendasikan di beberapa kelurahan sehingga terjadi perubahan skor area berisiko.Kata Kunci: Kota Cimahi, Peta Area Berisiko, Persampahan ABSTRACTCimahi City is one of the cities in West Java that still faces solid waste problems, such as the limited implementation of waste sorting activities, the limited number of temporary shelter sites, the indiscriminate waste disposal on river, open burning of solid waste, etc. In following up on these various waste problems and achieving the target of 30% waste reduction determined by the National Strategic Policy, an instrument is needed to analyze risk areas based on the level of risk of solid waste per village in Cimahi City. These risk areas are depicted in the form of maps by referring to the 2018 District/City Sanitation Strategy Guidelines. Risk areas are assessed through a score of 1 s.d. 4 for very low, low, high and very high risks. The score is obtained by multiplying the Impact parameters and Exposure parameters. The results of this study indicate that there are three villages with very high risk of solid waste, namely Kelurahan Cibeureum, Setiamanah, and Padasuka and one village with high risk of solid waste, namely Kelurahan Melong. The addition of the number of processing units was recommended in several villages so that changes in the score of risk areas occurred. Keyword: Cimahi City, Map of Risk Areas, Waste Solid

This paper is expected to encourage the professional sanitarian to seriously consider problems related to solid waste disposal. It is divided into four specific parts: (a) solid waste disposal, a universal environmental health problem; (b) public awareness;(c) the Solid Waste Disposal Act; and (d) solid waste disposal–a challenge. The term “solid waste disposal” includes storage at the point of production, collection, and transportation to the point of ultimate disposal. Solid waste disposal is an important facet of most all environmental sanitation programs. Today the professional sanitarian knows that many diseases are spread by improper solid waste disposal. In addition, improper solid waste disposal adversely affects many aspects of the environment. Until quite recently, public interest in solid waste disposal was minimal. This interest currently is high and the public expects appropriate action on the part of someone. The Solid Waste Disposal Act is indicative of public interest and provides several areas for improving solid waste disposal practices of the nation. Solid waste disposal presents a challenge to the professional sanitarian, and provides him with a real opportunity to fill the void in today's solid waste disposal management.

Incineration is the main way to dispose the municipal solid waste (MSW) in Taiwan. The amount of MSW is rapidly decreased during recent 10 years due to the policies implementation of waste reduction and resource recycle since 2003. Assessment of incinerator operation stop and transformation therefore becomes an essential issue. An evaluation framework was constructed and put into practice in this research. With the considerations of service status, operation performance, MSW treatment status and the impact level of stopping operation was integrated and assessed in the first stage. An optimal model was built for re-programming the MSW clean strategies of original service areas by taking account of MSW collection distance, design capacity of incinerators and the heating value of solid waste in the second stage. A case study was implemented for four incinerators in Kaohsiung City of southern Taiwan to demonstrate the feasibility of proposed assessment framework.

Abstract The impact of uncontrolled municipal solid waste disposal of 3800 tons per day on surface and groundwater in the downstream of Jawaharnagar dumping site was studied. The un-engineered solid waste dumping yard site spreading over an area of about 300 ha is located on topographic high (hillock), and falls in Madyala stream and Dammaiguda watersheds of Musi sub-basin. The area is underlain by granites of the Archaean age. Both surface and groundwater samples, collected covering hydrological cycles of 2011and 2012, were analyzed for major chemical constituents. During 2012, 15 samples of both seasons were tested for BOD, COD, and TOC. The mean values of some tested chemical constituents of surface water samples (15) were - EC 13066 m S/cm, TH 753, Na+ 813, K+ 530, HCO3− 978, Cl− 1304, and NO3− 262 (all in mg/l) which prove that the tanks and stream near dump yard were pools of leachate. The average values of contaminated groundwater samples among the four sampled sessions (17) indicate EC was above 5000 m S/cm, TH 1624, Cl− 1502, and SO42− 284 (all in mg/l) which were found much above the threshold values. Very few samples were found suitable for drinking purpose and most of the samples fall in Good class of WQI. Very high content of TOC, BOD, and COD in both surface and groundwater samples indicate the presence of organic pollutants sourced from domestic waste dumps. Wide temporal and spatial variability in the concentration of many ion species can be attributed to deviation in rainfall, topography, plume dynamics, and aquifer hydraulics. Low resistivity values (5 to 25 ohm.m) at a distance of 4 km from the dumping site and high infiltration rate (29 cm/hr) at Madyala stream, which were contaminant hotspots, indicate the mass flux was controlled by hydrological features. Scattered and limited distribution of contaminants can be accounted for heterogeneous nature of country rocks, retarded lateral and vertical flow of water which restricts the movement of contaminants to certain preferred pathways. The study supports the hypothesis of solid waste dumps were the epicenter of pollution which generates leachate and dissipate contaminants to the aquatic environment influenced by factors like soils, topography, and aquifer hydraulics and contaminant kinetics.

Coal self-combustion loses a large amount of coal resources in China's Xinjiang region, not only caused huge economic losses each year, but also caused serious environmental pollution problems. Through the coals on the ecological environment, including air, water, land resources, biological survival of both the environment and the geological environment,the article analyzed the impact of coal on the environment,and Proposed technical measures to combat coal fires.

An important component of the current interests in environmental problems concerns solid waste. Not only has public interest in solid waste disposal been substantial, but legislators have restricted ways by which solid wastes may be disposed. New Hampshire's State Legislature, for example, has passed a law requiring municipalities to cease all open burning by 1975.
