The One

NH3 is one of the major substances contributing to the secondary generation of PM2.5; therefore, management is required. In Korea, the management of NH3 is insufficient, and the emission factor used by EPA is the same as the one used when calculating emissions. In particular, waste incineration facilities do not currently calculate NH3 emissions. In the case of combustion facilities, the main ammonia emission source is the De-NOx facility, and, in the case of a power plant with a De-NOx facility, NH3 emission is calculated. Therefore, in the case of a Municipal Solid Waste (MSW) incinerator with the same facility installed, it is necessary to calculate NH3 emissions. In this study, the necessity of developing NH3 emission factors for an MSW incinerator and calculating emission was analyzed. In addition, elements to be considered when developing emission factors were analyzed. The study found that the NH3 emission factors for each MSW incinerator technology were calculated as Stoker 0.010 NH3 kg/ton and Fluidized Beds 0.004 NH3 kg/ton, which was greater than the NH3 emission factor 0.003 NH3 kg/ton for the MSW incinerator presented in EMEP/EEA (2016). As a result, it was able to identify the need for the development of NH3 emission factors in MSW incinerators in Korea. In addition, the statistical analysis of the difference between the incineration technology of MSW and the NH3 emission factor by the De-NOx facility showed a difference in terms of both incineration technology and De-NOx facilities, indicating that they should be considered together when developing the emission factor. In addition to MSW, it is believed that it will be necessary to review the development of emission factors for waste at workplaces and incineration facilities of sewage sludge.

An effective waste management system is, and has always been, essential infrastructure, particularly given the potential for waste to adversely impact the surrounding environment. In recent decades, however, there has been growing awareness of the scale, breadth and immediacy of those adverse impacts, and of the unsustainability of the enormous (and increasing) amount of waste society generates. Governments around the world have mobilised and there has been a widespread shift towards policies promoting circular economies, waste minimisation and maximised resource efficiency. Singapore is a case in point; despite having a traditionally high waste output and a waste management system dependent on waste incineration as the primary means of disposal, Singapore has committed to a zero waste future. This article presents a review of domestic waste management policy and law in Singapore. Several gaps in the legal framework are identified and considered against the broader context, leading to the conclusion that there is a material environmental vulnerability in the legal framework that should be redressed in order to entrench environmental protections and to align the law with Singapore's policy ambitions. Notwithstanding this deficiency, it is hard not to be optimistic about the future of domestic waste management in Singapore, as the government has made an ambitious policy commitment and appears to be pursuing it with vigour.

The objectives of this research were to compare the happiness and thinking styles of undergraduate students in the Physical Education and Sports Teaching Department and different departments, and to examine the relations between the students’ happiness levels and their thinking styles. Using the correlational study design 661, undergraduate students were determined by a convenience sampling method. Participants were selected in terms of being easily accessible from Gazi University, which is located in the Ankara province, Turkey. The analysis indicated that the Department of Physical Education and Sports Teaching students' average level of happiness was significantly higher than in some other departments. However, the Department of Physical Education and Sports Teaching students' need for cognition was not significantly different from the students from other departments. Physical Education and Sports Teaching students' faith in intuition was significantly higher than the Department of Guidance and Psychological Counseling students’. Besides, the happiness levels and thinking styles did not differ significantly by gender. There was a positive correlation between their faith in intuition and happiness. However, there was no significant relation between their happiness levels and need for cognition, nor need for cognition and their faith in intuition.

It is known that cement minerals hydration is accompanied with heat emission. Heat of hardening influences formation of a cement compound structure and its properties. It is important to reduce the heat quantity at continuous cementation of waste and filling of compartments of a repository or containers by a cement grout. For reduction of heating, it is necessary to use cement of mineral additives (fuel ashes, slag and hydraulic silica). Properties of ashes after domestic waste incineration can be similar to ones of fly fuel ashes. However, ash after domestic waste incineration is toxic industrial waste as it contains toxic elements (As, Cd, Hg, Pb, Sb, Zn). Utilization of secondary waste (slag and ash) of combustion plants is an important environmental approach to solving cities’ issues. Results of the research have shown that ashes of combustion plants can be used for radioactive waste conditioning. Coprocessing of toxic and radioactive waste is ecologically and economically effective. At SIA “Radon”, experimental batches of cement compositions are used for cementation of oil containing waste.

ABSTRAKSungai Silandak dan Singker merupakan sungai penting dalam sistem drainase Semarang Barat.Sungai tersebut telah dialiri limbah industri dan limbah domestik yang berasal dari pemukiman warga sekitar. Adanya masukan limbah industri dan domestik akan berpengaruh terhadap kualitas air sungai seperti peningkatan unsur hara yang dapat menyebabkan eutrofikasi. Tujuan dari penelitian ini adalah mengetahui beban pencemaran (TSS, Nitrat, Fosfat) yang akan bermuara ke Teluk Semarang serta mengkaji status pencemaran berdasarkan metode Indeks Kualitas Air pada Sungai Silandak dan Sungai Siangker. Materi yang digunakan dalam penelitian ini adalah contoh air yang diambil pada bagian hulu, tengah dan hilir.Metode penelitian menggunakan metode survei, teknik penentuan lokasi sampling bersifat purposive pada 6 titik lokasi sempling.Contoh air diambil menggunakan metode komposit sebanyak 500 ml pada pagi dan sore hari dengan interval waktu 1 minggu. Hasil yang diperoleh berdasarkan analisis beban pencemaran yang berasal dari Sungai Silandak yaitu TSS 838,31 mg/detik, nitrat 5,44 mg/detik dan fosfat 5,08 mg/detik dan Sungai Siangker TSS 417,76 mg/detik, nitrat 4,18 mg/detik dan fosfat 3,42 mg/detik. Kualitas air Sungai Silandak bagian hulu, tegah dan hilir secara berturut-turut termasuk dalam kelas tercemar berat, tercemar sedang dan tercemar sangat berat. Sedangkan kualitas air Sungai Siangker bagian hulu, tengah dan hilir secara berturut-turut termasuk dalam kelas tercemar berat, tercemar berat dan tercemar sangat berat. Kata kunci: Beban Pencemaran, Indeks Kualitas Air, Sungai Silandak, Sungai Siangker ABSTRACTSilandak and Siangker were the important rivers in drainage system on West Semarang. The rivers drained industrial and the domestic waste from around the residential. The industrial and domestic wastes influenced the quality of the waters as the improvement of nutriens that made eutrophication. The purpose of this study was to know the pollution load (TSS, nitrate, phosphate) that flew to bay of Semarang and to review status of pollution from Silandak and Siangker rivers based on the Water Quality Index. Samples of water from Silandak and Siangker rives were taken from the upstream, midstream and downstream. The method used in this study a purposive sampling method to determine on 6 sampling points. Water samples were taken 500 ml by composite in the morning and afternoon in a week. The ammount of pollution load from Silandak river was TSS 838.31 mg/second, nitrate 5.44 mg/second and phosphate 5.08 mg/second and the ammount from Siangker river was TSS 417.76 mg/second, nitrate 4.18 mg/second and phosphate 3.42 mg/second. The water quality of Silandak river from the upstream, midstream and downstream in a row classified as heavily polluted, moderately polluted and very heavily polluted class while Siangker river from the upstream, midstresm and downstream rin a row classified heavily polluted, heavily polluted and very heavily polluted class. Key word:Pollution Load, Water Quality Index, Silandak River, Siangker River
