Öğe Life Cycle Assessment of Construction of Water Supply Pipelines: A Case Study from Van, Turkey(2020) Baş, Bilge; Haidery, Jaweed AhmadPipelines that supply water from water resource to the reservoirs constitute an important part of water supply system construction. Inthis study, environmental impacts of construction of pipeline component of a water supply system in Van, Turkey are investigatedusing Life Cycle Assessment (LCA) methodology. Construction of pipelines is executed using conventional open cut system. Lifecycle inventory (LCI) of the study is generated using primary data gathered and GaBi Professional database is used for backgroundprocesses. CML 2001 was the environmental impact assessment method used. According to the results, the main contributors to AP,FAETP, GWP, HTP, MAETP are raw materials used for the production of pipelines which are high density polyethylene granules andcarbon black. Most of TETP is generated because of installation of pipelines and sand used for backfilling the pipe trenches isresponsible of this. Production and installation of pipelines end up with ADP due to the used materials. Transportation activitiesexecuted during the construction of pipelines have environmental impacts in every category considered; however, their contribution isnot significant compared to the other activities conducted.Öğe Life Cycle Assessment of Construction of Water Supply Pipelines: A Case Study from Van, Turkey(2020-04) Baş, Bilge; Haider, Jaweed AhmadPipelines that supply water from water resource to the reservoirs constitute an important part of water supply system construction.

As for all energy technologies, offshore wind farms (OWFs) will have both local and global negative and positive impacts. Understanding and quantifying these burdens and benefits requires a holistic sustainability assessment. This study tests and applies a novel (socio-) environmental impact assessment framework to quantify the monetized (socio-) environmental footprint and handprint of an offshore wind farm located in the Belgian Continental Shelf. This framework consists of a combination of two ways of integrating Life Cycle Assessment (LCA) and Ecosystem Services Assessment (ESA) to quantify both the site-specific and site-generic impacts on ecosystem services (ESs) over the lifetime of a human intervention. For the operation and maintenance stage of the OWF, impacts on three local ESs were quantified, i.e. offshore wind energy provisioning, nursery and habitat maintenance and aesthetic value, while for the other life cycle stages site-generic impacts on multiple ESs were calculated. A comprehensive list of data was inventoried to conduct both the LCA and ESA studies. The monetized impact results were then aggregated and monetized at the level of three areas of protection, i.e. human health and well-being, natural resources and ecosystem quality. The results show that the OWF has a net handprint of +euro85,196, mainly due to electricity production, while the absolute footprint (-euro4039) consists largely of impacts associated to the supply chain of materials to manufacture the offshore windfarm. Furthermore, this study compares the (socio-) environmental performance of an OWF with nuclear energy, which is used as benchmark because of its high importance for electricity supply in Belgium. This study is a first step towards a valuable contribution to understanding the multi-scale burdens and benefits of offshore wind energy, which can support decision-and policy-making.Öğe Türk Endüstrisi için Temiz Üretim ve Yaşam Döngüsü Değerlendirmesi Örnekleri(İstanbul Teknik Üniversitesi, 2023) Babuna, Fatoş Germirli; Baş, Bilge; Türkmen, Burçin Atılgan; Kanat, Nilay ElginözNüfus artışına paralel olarak ivme kazanan endüstriyel faaliyetler, küresel ölçekte çevre kirliliği yaratan odak noktalarının en önemlisidir. Güncel endüstriyel kirlenme kontrolü temiz üretim kavramını benimseyen bir yapıdadır. Temiz üretim ise proseslere, ürünlere ve hizmetlere sürekli uygulanan entegre, önleyici nitelik taşıyan bir çevre stratejisidir. Yaşam döngüsü değerlendirmesi (YDD), endüstriyel faaliyet kaynaklı istenmeyen çevresel etkilerin azaltılması, diğer bir deyişle temiz üretim yönünde doğru adımların atılması için kullanılacak objektif bir araçtır. Kimi durumda kullanılan enerji kaynağının değiştirilmesi, kimi durumda başka bir ülkede üretilerek ithal edilen girdilerin yerli yapım olanlarla değiştirilmesi ya da geri dönüştürülmüş malzeme kullanımı veya çıkan atıkların geri dönüşüme gönderilmesi çevresel etkilerin azalmasına neden olmaktadır. Bu çalışmada endüstride temiz üretim seçeneklerinin saptanmasında YDD kullanımına ait örnekler sunulmaktadır. Örneklerin tümü ülkemizde yerinden toplanmış verilerle yürütülen çalışmalara aittir. YDD’de girdi olarak başka coğrafyalar için oluşturulmuş veri tabanlarının kullanımı yerine ülkemize özel verilerin oluşturulmasının önemi vurgulanmıştır.
