As a result of Turkey's economic growth, industrial development has accelerated across the country and this has ultimately led to the environmental sector and waste management gaining importance. In Turkey, where there is a depletion of natural resources, the expansion of energy demand, and the orientation in environmental technologies, waste is no longer a problematic issue that needs to be eliminated; but it has become a source of raw materials whose processing and recycling can be achieved with today's technology. In the scope of sustainable development, the waste hierarchy includes the three priority targets. These are prevention of waste production, reuse, recycling, or recovery respectively. The method for non-recoverable wastes is landfilling with energy recovery if possible. In this context, this study aims to investigate the electricity generation potential of the solid wastes disposed at the Edirne Solid Waste Landfill Facility. When the amount of waste to be sent to the facility, which was assumed to have a 20-year economic life, increases by 5% in parallel with the population profile, it is seen that electricity production will go up rapidly until 2040. However, the results of the study present that the potential of methane production will fall as the stored waste age increases so that a significant decrease in electricity production should be expected from 2045 onwards. Once it is considered that the facility continues to produce electricity for a hundred years beyond 2040, the electricity generated from the facility will contribute to the electricity network and provide the avoidance of approximately 25 thousand tons of CO2 on a national basis.
In this study, solid waste characterisation of high-income, middle-income, low-income regions and market areas in Tekirdağ Metropolitan Municipality was carried out in winter and summer, 2016. As a result, the amount of organic wastes (kitchen wastes, park and green wastes) and packaging waste (paper, cardboard, bulky cardboard, plastics, glass, metals and bulky metals) in Tekirdağ were determined as 41.02% and 32.4% respectively, by waste sampling. When waste characterisation was analysed based on the districts, it was seen that paper and plastic waste is mostly produced from the Çorlu district. The reason for this could be the high level of welfare of the citizens living in Çorlu and the high number of working people compared to other districts due to the high density of industrial facilities. It was also seen that the ash percentage of waste is high in the districts of Hayrabolu, Şarköy, Muratlı, Marmaraereğlisi, Malkara and Saray, which are the districts not covered by natural gas distribution grid. Waste samples were characterised in the Tubitak Energy Institute Laboratory to determine the moisture content, calorific value and glow loss. The results showed that there is a high moisture and organic matter in the wastes, which makes the incineration method not suitable for the treatment of solid wastes in Tekirdağ. The results of this study highlighted that there is a potential for introducing recycling schemes especially in high income regions in Tekirdağ. To initiate such programmes, collected municipal waste could be separated in two streams in place; organics and co-mingled dry-recyclables.
An increase in population, energy demand, industrial activities and other technological developments inevitably cause large amount of waste to be produced. It is a known fact that traditional methods for the collection, transportation and disposal of wastes are not capable anymore to prevent health problems and economic losses. Any deficiency in the management of hazardous wastes, which constitute a significant part of solid wastes, has a range of negative effects for environmental health and safety. The aim of this study is to assess the situation of hazardous solid-waste management in Turkey. This was achieved by reviewing the rates of waste generation across the country. Current requirements and challenges in hazardous waste management are also discussed, and suggestions for solving problems are presented.The study results that the Kocaeli and Izmir, as the two cities with the larger population and industrial activities of Turkey, produces the largest amount of hazardous waste in Turkey. On the other side, Istanbul, which is the mostly populated city with advanced health service, is by far the largest medical waste producer across the country. This is followed by Ankara, the capital city of Turkey and then Izmir. Although hazardous waste management in Turkey has improved because of a strong governance and institutional involvement in recent years, efforts directed by scientific research are still required to enable robust waste management. These efforts will greatly aid decision makers such as municipal authorities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
