Tekstil sektöründe Avrupa Birliği IPPC direktifi ile uyum çalışmaları: BAT uygulamaları

TÜBİTAK ÇAYDAG15.01.2008Bu çalışma, Türkiye'de bir tekstil işletmesi için IPPC (Entegre Kirlilik Önleme ve Kontrolü) Direktifi kapsamında "Mevcut En İyi Teknikler"in ilk uygulaması ve değerlendirmesidir. IPPC Direktifi'nin hayata geçirilmesinde rehber olacak bir "en iyi uygulama örneği" tekstil sektörü için geliştirilmiş ve bu kapsamda işletme için "Mevcut En İyi Teknik" ihtiyaçları belirlenmiştir. Sürdürülebilir hammadde ve atık yönetimi için, ilk olarak, üretim süreçlerinin BREF ("Mevcut En İyi Teknikler" Referans) Dokümanı ile detaylı karşılaştırılması yapılmıştır. Su yoğun bir sektör olması sebebiyle, proseslerde geri kullanımı mümkün olabilecek atıksular belirlenip atıksu karakterizasyon çalışmaları yürütülmüştür. Proses atıksularında ve tesisten çıkan toplam atıksuda geri kazanım olanaklarının araştırılması için atıksu yönetim stratejisi oluşturulmuştur. Bu stratejiyle uyumlu olarak, üretim süreçlerinin BREF Tekstil Dokümanı ile detaylı karşılaştırılması yapılmış, gerek atıksuların geri kullanım amaçlı arıtılabilirliği gerekse su kullanımının ve atıksu üretiminin azaltımı üzerine çalışılmıştır. Uygulanabilir BAT önerileri fabrika yetkilileri ile birlikte çalışarak belirlenmiştir. Atıksu yönetimi çalışmalarının yanı sıra, enerji tüketiminin azaltılması, kimyasal değişikliği ve çevresel risk analizi çalışmaları da yürütülmüştür.This study was undertaken as the first application and evaluation of Best Available Techniques (BAT) within the context of the IPPC (Integrated Pollution Prevention and Control) Directive to a textile mill in Turkey. A “best practice example”, which will form a guideline for the implementation of the IPPC Directive, is to be developed for the textile sector; and within this context BAT requirements for the mill were determined. In order to achieve a sustainable resource and waste management; firstly, a detailed screening of the production processes with respect to BREF (BAT Reference) Textile Document was made. Being a water intensive sector, wastewater characterization study was conducted to identify the possible candidate wastewaters to be reused. A wastewater management strategy was adopted to investigate the possible reuse opportunities in the process wastewaters along with the composite mill effluent. In line with this strategy, production processes were analyzed in depth in accordance with the BREF Document not only to treat the generated wastewaters for their possible reuse but also to reduce the amount of water consumption and wastewater generation. Applicable BAT options were determined in cooperation with the mill staff. Besides studies related to wastewater management, minimization of energy consumption, chemical substitution and environmental risk analysis studies were also conducted

Clinical and histopathological characteristics of primary focal segmental glomerulosclerosis in Turkish adults

The data regarding primary FSGS (pFSGS) from different parts of the world differ. While the prevalence of pFSGS has been increasing in Western countries like the USA, it follows an inconsistent trend in Europe and Asia and a decreasing trend in Far Eastern countries such as China in the last two decades. There are undetermined factors to explain those national and geographic discrepancies. Herein, we aimed to reveal the current prevalence with clinical and histopathological characteristics of pFSGS in Turkish adults. This study includes the biopsy-proven pFSGS patients data recorded between 2009 and 2019, obtained from the national multicenter primary glomerulonephritis registry system of the Turkish Society of Nephrology Glomerular Diseases (TSN-GOLD) database. 850 of the 3875 primer glomerulonephritis patients(21.9%) have pFSGS. The mean age is 40.5 ± 14.2 and 435 (51.2%) of patients are male. Nephrotic syndrome is the most common biopsy indication (59.2%). 32.6% of patients have hematuria, 15.2% have leukocyturia and 7.8% have both. Serum creatinine, albumin, and proteinuria are 1.0 mg/dL (IQR = 0.7–1.4) mg/dl, 3.4 ± 0.9 g/dl, 3400 mg/day(IQR, 1774–5740), respectively. Females have lower mean arterial pressure (− 2.2 mmHg), higher eGFR (+ 10.0 mL/min/1.73 m2), and BMI (+ 1.6 kg/m2) than males. Thickened basal membrane(76.6%) and mesangial proliferation (53.5%) on light microscopy are the major findings after segmental sclerosis. IgM (32.7%) and C3 (32.9%) depositions are the most common findings on immunofluorescence microscopy. IgM positivity is related to lower eGFR, serum albumin, and higher proteinuria. The prevalence of pFSGS is stable although slightly increasing in Turkish adults. The characteristics of the patients are similar to those seen in Western countries. © The Author(s) 2024
