This paper reviews the state of the ?Bubanj? landfill near the City of Nis, Serbia, which has been used for 47 years and which is categorized as a non-sanitary landfill. We utilised the LandGEM 3.02 model, used for estimating landfill gas emission rates, to calculate the amount of landfill gases. Additionally, we measured the amount and composition of landfill gas in section S4 of the landfill from July 2014 to June 2015. We utilised the ALOHA software to estimate the fire-vulnerable zone. The results of our analysis show that the measured average methane emission is higher than the calculated emission. The difference between the measured average emission and calculated emission of methane is logical, as the measurements were performed in an active section, where methane emission higher than in inactive sections is to be expected. Based on the measured methane emissions during one year, we conclude that the methane emission drops as the ambient temperature drops. This paper showcases the state of the ?Bubanj? landfill, which is highly unsatisfactory in terms of environmental and fire protection because of landfill gas generation.

This paper discusses fires that occur in sanitary landfills as a result of oxidation processes in the landfill body. The paper provides an overview of the causes and incidence of landfill fires, as well as their classification. Finally, it analyzes fire occurrence indicators.

The gases produced from Sanitary Landfill are to be monitored and collected so as not to cause environmental pollution. TPA Bangklet in Bangli District, Bali Province iscurrently being reviewed and further developed to be pilot Sanitary Landfill in Indonesia. A system of monitoring and capturing or collecting LFG (Landfill Gas) has been done toBangklet’s Sanitary Landfill of the dry Cell Pilot Plant, especially for the second layer. LFG measurement results show the average value of 32.99% for CH4, 31.87% for CO2, 5.4% for O2 and up to 29.68% for other gases. But the arrests and the collection of LFG system still needs improvement, because there are some leaks that led to the entry of oxygen into the system and vice versa the LFG is released into the atmosphere. It is suggested that the pattern of capture, and utilization of LFG monitoring system have to be applied to all Sanitary Landfills located in Indonesia.

Green House Gas Emissions

TPA mengemisikan Landfill Gas (LFG) yang mengandung paling banyak metana dan karbondioksida. Metana memiliki efek pemanasan beberapa kali lebih kuat dalam menyebabkan pemanasan bumi dibandingkan dengan CO2. Oleh karena itu pemanfaatan metana TPA sebagai bahan bakar pembangkit listrik telah menjadi target negara-negara berkembang untuk mengurangi green house gas emissions (GHGs). Sebelum membangun Pembangkit Listrik Tenaga Sampah (PLTSa) di sebuah TPA dibutuhkan serangkaian studi untuk menentukan apakah PLTSa layak dibangun di TPA tersebut, salah satunya adalah mengetahui jumlah LFG dari TPA untuk menghitung potensi energi listrik yang dapat dihasilkan. Tujuan dari penelitian ini adalah mengetahui jumlah LFG yang dihasilkan oleh TPA Makbon Kota Sorong dan selanjutnya menghitung  potensi PLTSa berdasarkan kandungan metana dalam LFG. Tahapan penelitian dimulai dari pengumpulan data kuantitatif berupa jumlah ton sampah yang masuk ke TPA setiap tahun, ukuran TPA, dan jumlah penduduk. Untuk estimasi LFG digunakan LandGEM-v302 yang diunduh dari website US EPA. Sedangkan untuk estimasi potensi energi listrik digunakan rumus. Dari hasil penelitian, TPA Makbon Kota Sorong model sanitary landfill menghasilkan emisi maksimal metana sebesar 7,321 x 105 m3 pada tahun 2035 jika  diasumsikan tahun 2020  mulai menerima sampah. Berdasarkan hasil penghitungan dengan menggunakan rumus diperoleh potensi energi listrik maksimal yang dihasilkan 1,685 x 106 kWh.

Minimal Environmental Impact

Waste disposal is an element of integrated waste management. Properly designed projects for landfill construction ensure safe waste disposal with minimal environmental impact. The first part of this paper discusses and analyses waste management and landfills in Serbia. The second part describes the factors contributing to landfill gas (LFG) generation. The influence of several factors on LFG generation is shown on the basis of measurements of LFG components concentrations and of the analysed wastewater samples taken from “Pirot” Regional Sanitary Landfill. Depending on the contributory factors, provision of optimal conditions at the landfill accelerates waste decomposition, in turn producing larger quantities of LFG, with the ultimate goal of proper controlled LFG management. The paper presents guidelines for controlled LFG management, the implementation of which would automatically meet the requirements and recommendations of both domestic and European legislation.

Environmental Assessment (EA) is the identification, prediction and evaluation of Environmental impacts. Environmental Monitoring transforms EA from a one time pre-project document to a continual assessment of impacts. Post project analysis concerns life cycle environmental management and environmental studies during project implementation. This study illustrates significance of Post project Environmental Monitoring and Impact Assessment using a factual example of Gokarna Sanitary Landfill Site (GLFS) after final operation and closure. The environmental inventory, the preventive and compensatory measures adopted by GLFS were studied and some modes of public involvement, economic measures and regulatory measures were analyzed during the construction and operation of the GLFS. Environmental inventory of the site indicated that GLFS might constitute concrete environmental conflict. The result of handpicking analysis showed that risk of medical and industrial hazardous waste cannot be excluded. Water and leachate analysis indicated that the impact of disposal is still pronounced at the site and ground water pollution may be dispersing to the general ground water flow direction. Soil analysis indicated that impact of disposal is pronounced on similar trends in two sites in landfill site. PH, BOD and COD values of leachate indicated that a good biodegradation of organic wastes (i.e. stable methane process) is going on the site and opens a potential for using landfill gas as an energy resource. The public participation, and economic measures studied through questionnaire method confirmed that during operation phase there was inadequate compliance with the planning and operational strategies at implementation that is also a major issue environmentally. There were no provisions for monitoring hazardous wastes, surface and ground water pollution and landfill gas during the operation phase. This study intends to conclude for regular Environmental Monitoring and Post project Impact Assessment for corrective actions and also for the construction and successful operation of similar projects. Possibility of Post project Environmental Monitoring and Impact Assessment in environmental policy making is also considered.
