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.

Benghazi, like other cities in Libya, faces problems associated with poorly managed solid waste operation. The uncertainty of the types of municipal solid waste (MSW) it is the challenge that, hinders chosen the best method for solid waste management. This study deals composition analysis of the city’s MSW as, sustainable waste management options. To specify types of MSW the samples collection in wet seasons and dry seasons. Number of samples collected as 40 samples per season. And to get a representative sampling, in this case employed a range of sampling techniques including stratified sampling, systematic random sampling, and purposive sampling. The samples was collected, mixed and then weighed as, kilogram (Kg). The samples were characterized. as, paper, glass, metals, plastics, textiles, non-food, food and putrescibles, misc-combustibles, misc. non-combustibles, household hazardous waste. And then the samples weighed again to determine the proportion of each type. Finally, this study forwarded some important conclusion and recommendations towards improving the current situation.

Healthcare Waste Management

The management and treatment of healthcare waste (HCW) are of great concern owing to its potential hazard to human health and the environment, particularly in developing countries. Nowadays, various technological alternatives are gaining momentum as efficient and favorable waste management options across the world. However, selecting a suitable technology as well as an effective waste management approach for the treatment of HCW is still a challenging task for the municipal authorities. This study renders a comprehensive analysis of healthcare waste management (HCWM) practices and the technological options for its better management through a case study in Khulna, the southwestern division of Bangladesh. A number of healthcare establishments (HCEs) in the study area were selected and a questionnaire survey, as well as field investigations, was performed to find out the present status of HCWM and its limitations. An assessment of different technological alternatives was also carried out using Sustainability Assessment of Technologies (SAT) methodology which could pave the way for treating hazardous waste more efficiently in the Khulna metropolitan area. The study revealed that the overall HCW generation rate and hazardous HCW generation rate in Khulna city were 0.90 kg bed−1 day−1 and 0.18 kg bed−1 day−1, respectively. Assessment of management system revealed that 56% (n=38) of workers did not receive any form of training in the handling of hazardous waste. Around 54% (n=47) of them did not use any safety equipment or clothing. It has been found from the study that, among different technological alternatives based on the final score, incineration was the most suitable option for the treatment of hazardous waste in Khulna. Finally, some guidelines have been put forward to improve its existing management practices.

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

In the article the estimation of ecological safety of schemes of handling was executed building wastes that are used presently. А comparative analysis is conducted with the perspective methods of handling wastes (recycling, incineration). Basic indicatos are set for the estimation of ecological safety of construction. The quantitative values of environmental indicators for each of the ways of waste management have been deter-mined. Results show that in terms of the Global Warming Potential, the most environmentally friendly treat-ment was recycling, followed by incineration and lastly landfilling.
