Bursa kentinde uygulanan katı atık yönetim modeli, kentin atık yönetim ihtiyaçlarına yanıt verirken, her faaliyet gibi aynı zamanda çevre üzerinde bir yük oluşturmaktadır. Bu çalışmada Bursa’da kentsel katı atık yönetiminden kaynaklanan çevresel yükün analiz edilmesi ve bu yükü azaltmak için yapılması gerekenlerin belirlenmesi amaçlanmıştır. Çalışma kapsamında çevresel yük, yaşam döngüsü değerlendirmesi (YDD) ve deponi gazı etki modellemesi ile analiz edilmiştir. Uygulanan YDD sürecinde kentsel katı atığın yönetimi boyunca izlediği toplama, taşıma, aktarma istasyonuna iletilme, düzenli depolama alanında depolanma ve oluşan gazdan enerji eldesi süreçleri sistem sınırlarına dahil edilmiştir. YDD çalışması için SimaPro 8.5.0 yazılımı, deponi gazının değerlendirilmesi için EPA LandGem Modeli kullanılmıştır. Bu çalışmanın sonucunda Bursa’da bir yılda deponi gazından enerji üretim tesisiyle azaltılan toplam emisyonun yaklaşık 0,5 milyon ton karbondioksit eşdeğeri düzeyinde, bir yılda depolama yoluyla bertaraf edilen kentsel atığın küresel ısınmaya katkısının ise yaklaşık 44 milyon ton CO2 eşdeğeri düzeyinde olduğu görülmüştür. Katı atık yönetiminin kirli sis (smog) oluşumuna katkısı yaklaşık 55 milyon ton O3 eşdeğeri, ozon tabakasındaki incelmeye katkısı 647 kg CFC-11 eşdeğeri, kanserojen madde oluşumuna katkısı 22.5 CTUh ve solunum etkisi 1732 ton PM10 eşdeğeri olarak hesaplanmıştır.
The solid waste management model applied in the city of Bursa responds to the city’s waste management needs, while, like every activity, it also creates a burden on the environment. This study aims to analyze the environmental burden resulting from urban solid waste management in Bursa and determine what to do to reduce this burden. The study was analyzed through environmental burden, life cycle assessment (YDD) and storage gas impact modeling. During the implemented YDD process, the collection, transport, transfer to the transfer station, storage in the regular storage area, and the processes of gas-generated energy gloves have been incorporated into the system limits. SimaPro 8.5 for YDD work. The 0 software used the EPA LandGem Model for the assessment of the storage gas. According to this study, the total emissions reduced from the stock gas in a year by the energy production facility at the level of approximately 0.5 million tons of carbon dioxide equivalent, while the contribution of urban waste removed through storage in a year to global warming at the level of approximately 44 million tons of CO2 equivalent. The contribution of solid waste management to the formation of dirty smog (smog) is estimated as approximately 55 million tons of O3 equivalent, the contribution to the study in the ozone layer is 647 kg of CFC-11 equivalent, the contribution to the formation of carcinogenic substance is 22.5 CTUh and the respiratory effect is 1732 tons of PM10 equivalent.
Solid waste management model of the city of Bursa that responds to the waste management needs of the city creates a burden on the environment, like every other activity. The purpose of this study was to analyze the environmental burden arising from municipal solid waste management in Bursa and to determine the necessary steps to be taken to reduce this. Environmental burden was analyzed by using life cycle assessment (LCA) approach and landfill gas impact modeling. Municipal waste management steps, namely collection and transport, transport to transfer station, landfilling, energy conversion from landfill gas, were included into the system boundaries in LCA. SimaPro 8.5.0 software was used for the LCA study, and EPA LandGem model was employed for the assessment of the impact by landfill gas. The findings of the study showed that the emissions reduced by the landfill gas to energy plant in one year is approximately 0.5 million ton CO2 equivalent, and the contribution of municipal waste, which is mainly managed by landfilling, to the global warming in one year is approximately 44 million ton CO2 equivalent. The approximate contribution of municipal waste management to smog formation was calculated as 55 million ton O3 equivalent, the contribution to depletion of ozone layer was 647 kg CFC-11 equivalent, and to carcinogenic substance formation was 22.5 CTUh. Its inhalation impact was found as 1732 ton PM10 equivalent.
