The results of the life cycle assessment (LCA) of oil waste (OW) management and disposal of refineries are presented, which include environmental impacts beyond the implementation of the techniques themselves, but also the production of the necessary material (reagents, materials) and energy (electricity, fuel, steam). LCA demonstrated that the most significant impacts of oil-containing waste treatment and disposal methods are in the categories Ecotoxicity (for freshwater)" and "Human toxicity" (cancer and non-cancer diseases)" resulting from the burning of fossil fuels and the emission of heavy metals (zinc, copper, vanadium, cobalt, chromium, nickel and lead).

This paper presents the preliminary results of a Life Cycle Assessment (LCA) study comparing different wastewater treatment works, operated by Thames Water Utilities Ltd. in the UK. Fifteen works have been studied, representing a range of size and type of treatment works. Five management regimes for centralising sludge treatment and disposal were analyzed in the context of LCA to provide guidance on choosing the best practicable environmental option (BPEO). Consideration of Global warming potential indicates that the four proposed management regimes with centralisation of sludge for treatment and disposal, as adopted by Thames Water Utilities Ltd., is an environmental improvement upon the current practice. One of these options, that of complete centralisation and composting of sludge prior to disposal, exerts the least environmental impact with respect to Global warming potential. This suggests that the adoption of composting at Crawley is environmentally preferable to increasing the digestion facility at this works.

Alternative Scenarios

ABSTRACT The primary municipal waste treatment in Tuban Regency, East Java, was landfilling, besides the small amount of the waste was turned to compost. Landfilling causes global warming, which leads to climate change due to CH4 emission. This environmental impact could be worst by the population growth that increases the amount of waste. This study aimed to evaluate the environmental impact on waste management in the Gunung Panggung landfill in Tuban Regency and its alternative scenarios using Life Cycle Assessment (LCA). Four scenarios were used in this study. They are one existing scenario and three alternative scenarios comprising landfilling, composting, and anaerobic digestion. The scope of this study includes waste transportation to waste treatment which is landfilling, composting, and anaerobic digestion (AD). The functional unit of this analysis is per ton per year of treated waste. Environmental impacts selected are global warming potential, acidification potential, and eutrophication potential. The existing waste management in Gunung Panggung landfill showed the higher global warming potential because of the emission of CO2 and cost for human health, which is 6.379.506,17 CO2 eq/year and 5,92 DALY, respectively. Scenario 3 (landfilling, composting, and AD; waste sortation 70%) showed a lower environmental impact than others, but improvements were still needed. Covering compost pile or controlling compost turning frequency was proposed for scenario 3 amendment. Keywords: environmental impact, landfill, life cycle assessment, waste management   ABSTRAK Landfill merupakan pengelolaan sampah utama di tempat pemrosesan akhir (TPA) Gunung Panggung Kabupaten Tuban. Selain landfill, pengomposan diterapkan untuk mengolah sebagian kecil sampahnya. Landfill menghasilkan gas metana yang menyebabkan pemanasan global dan memicu perubahan iklim. Pertambahan penduduk memperbanyak sampah yang perlu diolah di TPA dan dapat memperparah dampak lingkungan yang ditimbulkan. Tujuan penelitian ini adalah menilai dampak lingkungan dari pengelolaan sampah eksisting di TPA Gunung Panggung Kabupaten Tuban Jawa Timur beserta skenario alternatifnya menggunakan Life Cycle Assessment (LCA). Terdapat satu skenario eksisting dan tiga skenario alternatif pengelolaan sampah yaitu landfilling, pengomposan, dan fermentasi anaerob (anaerobic digestion). Ruang lingkup studi meliputi pengangkutan sampah, pengelolaan sampah dengan cara pengomposan, Anaerobic Digestion (AD), dan landfill. Satuan fungsional yang digunakan yakni ton sampah yang diolah per tahun. Dampak lingkungan yang dipelajari di antaranya: pemanasan global, asidifikasi, dan eutrofikasi. Dampak lingkungan skenario eksisting menunjukkan nilai tertinggi terutama pada pemanasan global (6.379.506,17 CO2eq/tahun) dan kerugian pada kesehatan manusia (5,92 DALY). Skenario alternatif 3, yang meliputi pengelolaan secara landfill, pengomposan, dan AD menunjukkan dampak lingkungan yang kecil, namun memerlukan perbaikan. Perbaikan untuk skenario 3 yaitu dengan menambahkan penutup pada tumpukan kompos atau mengontrol frekuensi pembalikan kompos untuk mengurangi emisi NH3. Kata kunci: dampak lingkungan, life cycle assessment, pengelolaan sampah, tempat pemrosesan akhir
