“…The results indicate that the proportion of organic content affects the moisture content. Initial decomposable VS of waste were found to be 55% (Lakshmikanthan and Sivakumar Babu, 2017), and the obtained average value in this study was 56.22%. The average pH of mixed waste was found to be 5.12 in this study because of the high amount of food waste in landfills.…”

Quantification, measurement of quality, post-treatment, and leachate control has been a significant problem due to the dumping of waste in an unscientific manner across the globe, and especially in developing countries like India. In this context, the objective of this study was to investigate the degradation of fresh mixed municipal solid waste (MSW) in an anaerobic landfill reactor operated with rainfall addition in laboratory conditions. Experiments were carried out in a landfill reactor of 1 m length × 1 m width × 1.1 m height. The reactor was simulated with 50 years weighted average actual rainfall rate of India. It contained the waste composition of 73% wet waste (food and kitchen) and 27% dry waste (paper, plastic, wood, textiles, and others). The leachate parameters were continually monitored for 39 weeks. In the fresh MSW landfill reactor it was evident that concentrations of leachate parameters were high initially, and there was a significant decrease in BOD5 (7041–39310 mg L−1), COD (15692–71630 mg L−1) and TS (9077–33200 mg L−1) in leachate. Therefore, rainfall had a direct influence on leachate quality. The developed first-order decay models were used for BOD5, COD, and total solids with adjusted R2 of 0.83, 0.92, and 0.96, respectively. Therefore, this model can be applied for leachate strength estimation at any given time from the period of deposition of waste under similar rainfall and waste compositions, and is largely applicable in India and tropical areas. This study is expected to be a good simulation for cities with the waste composition of high wet waste (>70%) as the estimations of important design parameters such as BOD5, COD, VFA, and NH4+-N were studied in this research. As the importance of moisture (precipitation) has been established in this study, some moisture additions can be designed in areas with low rainfall, such as arid zones.

“…Reaksi tersebut dapat dipercepat dengan mengoptimalkan kandungan air dan udara sehingga aktivitas mikroba menjadi meningkat dan penguraian bahan organik menjadi lebih cepat. Kondisi demikian membuat TPA berfungsi sebagai bioreaktor sehingga disebut juga dengan TPA Bioreaktor (2,3) . Sampah organik dan air yang berfungsi sebagai bahan baku utama serta sampah anorganik, akan bereaksi dengan oksigen yang sangat sedikit (anaerob) sehingga dihasilkan gas-gas tertentu, air lindi serta material organik seperti humus sebagai produk utama (4) .…”

High population growth rate has stimulated the increase of energy consumption. Therefore, the use of renewable energy sources such as methane gas from landfill has also been encouraged. It is necessary that landfill methane gas is purified to increase its concentration. Common method to purify methane gas is water scrubber method. The aim of this research was to evaluate the effectiveness of landfill methane gas purification using a spray water scrubber (water scrubber method), a water column scrubber (bubbling methods) and the combination of both methods to increase the content of landfill methane. The experiment was conducted in the dry season and rainy season. Results of the study concluded that water scrubber was the most effective method for increasing methane gas concentration. The average increase of methane gas in the dry season were 33.32% (water scrubber) and 23.79% (combination of bubbling and water scrubber), and in the rainy season 8.89% (water bubbling) and 2.75% (combination of water scrubber and water bubbling). The increase in methane gas was due to a decrease in CO2 gas. In addition, there was an increase of H2O content in biogas from landfill after the purification process.Keywords: Landfill, methane gas, purification, water scrubberABSTRAKTingginya laju pertumbuhan penduduk telah memacu konsumsi energi yang terus meningkat. Oleh karena itu diperlukan upaya pemanfaatan sumber energi terbarukan, yang salah satunya adalah gas metana yang berasal dari TPA sampah. Keinginan untuk meningkatkan kandungan gas metana TPA diperlukan upaya purifikasi, menggunakan metode water scrubber. Penelitian ini dilakukan dengan tujuan mengetahui efektivitas purifikasi gas metana TPA dengan menggunakan metode pengaliran gas dalam percikan air (water scrubber) dan metode pengaliran gas dalam air atau water bubbling (serta kombinasi keduanya) untuk meningkatkan kandungan gas metana TPA, yang dilakukan pada musim kemarau dan musim penghujan. Hasil penelitian menyimpulkan bahwa water scrubber merupakan metoda yang paling efektif untuk meningkatkan kandungan gas metana. Rata-rata peningkatan gas metana pada musim kemarau dan musim penghujan, berturut-turut sebesar 33,32% (water scrubber), 23,79 (kombinasi water bubbling dan water scrubber), 8,89% (water bubbling) dan 2,75% (kombinasi water scrubber dan water bubbling). Peningkatan gas metana tersebut terjadi karena adanya penurunan gas CO2. Selain itu, terjadi peningkatan kandungan H2O pada biogas dari TPA setelah proses purifikasi.Kata kunci: TPA, gas metana, purifikasi, water scrubber.

“…For that purpose, stabilization/solidification of solid wastes by use of lime, cement, etc. is used (Dermatas and Meng, 1996, 2003; Lakshmikanthan and Sivakumar, 2017; Zhang et al, 2015). The majority of CCR residues such as fly ash and bottom ashes have been attracting more attention towards the use of alternative construction materials.…”

Fluidized bed combustion bottom ash: A better and alternative geo-material resource for construction

Though the majority of research on fly ash has proved its worth as a construction material, the utility of bottom ash is yet questionable due to its generation during the pulverized combustion process. The bottom ash produced during the fluidized bed combustion (FBC) process is attracting more attention due to the novelty of coal combustion technology. But, to establish its suitability as construction material, it is necessary to characterize it thoroughly with respect to the geotechnical as well as mineralogical points of view. For fulfilling these objectives, the present study mainly aims at characterizing the FBC bottom ash and its comparison with pulverized coal combustion (PCC) bottom ash, collected from the same origin of coal. Suitability of FBC bottom ash as a dike filter material in contrast to PCC bottom ash in replacing traditional filter material such as sand was also studied. The suitability criteria for utilization of both bottom ash and river sand as filter material on pond ash as a base material were evaluated, and both river sand and FBC bottom ash were found to be satisfactory. The study shows that FBC bottom ash is a better geo-material than PCC bottom ash, and it could be highly recommended as an alternative suitable filter material for constructing ash dikes in place of conventional sand.
