“…CBA has been applied to many different projects, such as crop irrigation (Al-Karaki, 1998), surface water treatment regulations , groundwater quality improvements (Yadav and Wall, 1998), health risks from drinking water , improvements to sewer systems (Schultz et al, 2004), rainwater harvesting (Ngigi et al, 2005), water reallocations (Messner et al, 2006), biomass-recovered fuel (Petrou and Mihiotis, 2007), and optimal planning of a municipal solid waste management system (Chang et al, 2012). This research illustrates that CBA could be incorporated into an integrated physical, environmental, and economic model to support planning and policy-making decisions related to water resources.…”

“…This situation is complicated with the fact that two third of Indonesian territory are sea. Another issue from the open dumping landfill is landfill gas (LFG) generated when the waste decomposed [7]. LFG is mostly composed of Methane (CH4) and carbon dioxide (CO2) that categorized as greenhouse gases (GHG).…”

Like most cities in the world, population in Indonesia continues to grow every year. Problems that can arise from this are the increasing amount of municipal solid waste (MSW) production and the growing demand for electricity. To deal with the problems, Indonesian government runs 3R (Reduce, Reuse and Recycle) and WTE (Waste to Energy) Programs simultaneously. 3R program aims to reduce the number of waste, while WTE program aims to generate electricity as an alternative energy source. This study aims to find out the optimal proportion of MSW treated through the 3R and WTE programs. For the purpose, a goal programming model has been developed and solved using LINGO 11. The results showed that the optimal proportion of MSW through the 3R program is 49.90%, 12.37% through WTE program. This leaves 37.73% of waste untreated. The electricity generated from WTE program reached 1,229.695 GWh, total emissions that can be saved is 1,809,208.2 tons CO2 equivalent and total land-use for the programs is 4,036,239.1 m 2 . This study was enriched by performing some scenarios, i.e. adding budget allocation of WTE program, tightening the limit of total emission from waste management and reducing the limit of land-use for waste treatment. AbstractOptimasi Program 3R dan WTE untuk Sampah Perkotaan di Indonesia. Seperti umumnya kota-kota di dunia, penduduk kota-kota besar di Indonesia terus bertambah tiap tahun. Keadaan ini memunculkan dua permasalahan yaitu bertambahnya jumlah sampah kota (MSW) dan bertambahnya permintaan akan listrik. Untuk mengatasi permasalahan tersebut, pemerintah memunculkan program 3R (Reduce, Reuse, and Recycle) dan program WTE (Waste to Energy) secara bersamaan. Program 3R bertujuan mengurangi jumlah sampah yang dibuang sedangkan program WTE bertujuan memanfaatkan sampah sebagai alternative untuk menghasilkan listrik. Penelitian ini untuk menjawab berapa porsi sampah yang optimal untuk digunakan untuk membangkit listrik dan berapa untuk 3R. Untuk tujuan tersebut telah dibuat model goal programming dan dipecahkan dengan menggunakan software optimasi Lingo release 11. Hasil running dari model yang dibangun menunjukkan bahwa porsi MSW yang dapat dikelola lewat 3R adalah 49,90%, lewat WTE 12,37%. Sisanya 37,73% sampah tidak terkelola. Listrik yang dihasilkan dari program WTE ini mencapai 1.229,695 GWh. Emisi yang dapat dikurangi sebesar 1.809.208,2 tons CO2 equivalen dan total lahan yang digunakan adalah 4.036.239,1 m 2 . Dalam penelitian ini juga dilakukan beberapa skenario yaitu penambahan alokasi dana pada program WTE, pengetatan emisi dan berkurangnya luas lahan yang dapat digunakan.

“…According to [6,7], the waste management sector contributes 5% to global greenhouse gases emission. There are many studies which have investigated the waste management system and the emission of greenhouse gases [8][9][10][11][12][13]. A study was conducted by [14,15] to quantify carbon emission and emission reductions related to waste management activities.…”

Life Cycle Assessment Modelling of Greenhouse Gas Emissions from Existing and Proposed Municipal Solid Waste Management System of Lahore, Pakistan

Open Dumping of indiscriminate municipal solid waste (MSW) remarkably contributes to global warming (GW). Life Cycle Assessment modelling may be a useful tool for assessing the best waste management option regarding GW potential. The current study evaluates the contribution of an existing MSW management (MSWM) system to greenhouse gases in Gulberg Town, Lahore, Pakistan. This research also presents a comparison of scenarios with different waste management options. Life Cycle Assessment methodology has been used to conduct the study. EASETECH has been used for modelling. The short-term scenarios (STSs) have been developed to promote the thinking of integration of treatment technologies in the current waste management system within a few months. The results show that the major contribution to the total emissions comes from the anaerobic digestion of organic material from open waste dumps. Currently, recycling is the best treatment option for reducing the CO 2 -eq values in the study area. It was clarified that recycling is the best option for reducing the CO 2 -eq values, whereas biogasification comes in second in terms of savings and reduction. The integration of recycling and biogasification techniques would be a good solution.
