Öğe Compost production experience from municipal solid waste, in Istanbul(2006) Borat M.; Celik T.; Bayat C.TOC (Total Organic Carbon), TKN (Total Kjedhal Nitrojen), tP (total Phosporus), C/N (Carbon/Nitrogen ratio) contents and other properties of Municipal Solid Waste, in İstanbul are suitable for Compost Production. Compost is an extremely useful agent in agriculture, provides humous to soil, improves its porosity, workability, aeration and needless to say improves water absorption capacity. It also helps increasing the number of saprofit micro organisms and helps plants to get more of fertilizers. Another advantage of compost production is surely to decrease the volume of the waste to be placed in sanitary landfills. This means more longer service periods, which is extremely important for a huge metropole like İstanbul. The Compost plant, which is using aerobic fermentation process, was put in service in September 2001. It has a capasity of 700 tons per day in one shift. 700 tons of municipal waste per day screened through 80 mm sieve. Approximately 300 tons of material per day which passes through is sent to fermentation process. Out of the rest 400 tons per day, approximately 10% (40 tons) is sent to sorting by hand unit for resource recovery. Here, plastic, paper, cardboard and other material are regained. The rest 360 tons per day is sent to sanitary landfill for burrying. The material, which is suitable for composting, then screened through 10 mm sieve. The part which pass through this sieve is again sent to sanitary landfill because it may cause delay in fermentation process. The rest, which did not pass through 10 mm sieve, is taken into 8 fermentation units. 3 of this units are fully covered. Waste is spread within the units with 2 m. thickness. Humidity is controlled within these units, water is added if necessary and units are continuously aerated. In the first unit, after 3 days, tempeature increases up to 65-70 0C. Thus, pathogen micro organizms in the waste are got rid off. In every unit, solid waste inhabited a week. Hence, complete fermentation process is thus completed within 8 weeks. The row compost obtained is approximately 200 tons per day. After sieveing 100 tons of fresh compost is obtatined. It is than stored in an open air for maturation. Than it is used in parks, gardens, and green areas around streets and motorways in the vicinity of İstanbul Metropolitan Municipality. © 2006. International Scientific Conference SGEM.Öğe A general comparati?ve evaluati?on of the exi?sti?ng legal procedures concerni?ng the soli?d and hazardous waste management i?n the European uni?on and i?n Turkey(2007) Demir G.; Celik T.; Bayat C.Technological developments in 20. and 21. centuries have highered up standards of living and created welfare and more comfortable living conditions for mankind. However, together with the increasing world population, environmental problems have also increased and diversified based on various reasons. Therefore, with the aim of solving the existing air, water and earth pollution problems and taking them under control, laws and regulations have been put into force and announced both internationally and domestically. These laws and regulations have been renovated and new arrangements have still been made. In this study, we have made a general comparative evaluation of the existing legal procedures concerning the solid and hazardous waste management of the European Union and Turkey who maintains negotiations on integration into the union.Öğe Global warming and importance of building isolation(2008) Eren E.; Celik T.This paper will first discuss the environmental pollution that threatens the world's presence and its consequences. Then, it will concentrate on one of the most important concequences of environmental pollution, the global warming, its antecedents and activities that result in CO2 emition. The negative effect of CO2 and greenhouse gases on the atmosphere, on the seas, climate changes, melting of the icebergs and the resulting scarcity, starvation, desertification will be explained. As one of the reasons of global warming, our topic will be buildings without isolation and how to reduce the CO2 released from these buildings. Especially we will present our ideas on how a good isolation would reduce heat loss in the buildings and help energy savings. Then we will good show an example of a house with good isolation 'Passive House' explain the terminology, the characteristics and being of the 'Passive House'.Öğe Removal of copper (CU) from municipal solid waste (MSW) compost using batch washing(2006) Bayat C.; Ozbas E.E.; Celik T.This paper deals with the removal of copper from Municipal Solid Waste (MSW) compost using Na2 and a mixture of Na2S2O5 and Na2 in the batch mode. At the end of extraction studies, for 3 hours at 1:25 solid:liquid ratio by using 0.05 M Na2EDTA, 100% removal yield was obtained for Cu. 100% heavy metal removal yield was obtained with 0.01 M Na2EDTA and 0.1 M Na2S2O5, at 1:6 solid:liquid ratio, for Cu in this study. © 2006. International Scientific Conference SGEM.Öğe The use of glass as a packaging material, recycling and a general outlook of the procedures in Turkey(2008) Albayrak S.; Demir G.; Celik T.; Bayat C.The world population has been increasing rather fast along with an inevitable rise in the process of industrialization. Today, the world population has reached 7.2 billion and it has been struggling for better standards of life. However, the ecological equilibrium has been tilted off as a result of depletion of natural resources and of the damage to the nature in order to obtain such packaging materials used for the needs of 7.2 billion people, mainly in terms of food and catering sectors as well as textile, furniture and the like. In today's world, people tend to consume foods and beverages known as "fast food" so as to save their time in a world of competition which renders volumes of packaging wastes naturally. In this context, packaging items made of glass are worth considering and relatively more advantageous than others, since they are recyclable and hygienic. Hence, in this work there have been some evaluations and analysis made for glass as a packaging material in Turkey.
