Sustainability and recycling opportunities in the textile and apparel sector [Teksti'l ve konfeksi'yon sektöründe sürdürülebi'li'rli'k ve geri' dönüşüm olanaklari]

A significant increase in textile consumption has occurred as a result of global population growth and overall improvement of living standard. The total volume of textile and fashion production at the global level is estimated to be more than 80 million tons annually, and therefore improving the environmental performances of this industry is vital. Recycling of textile waste materials is gaining importance worldwide due to shortages of natural resources and increasing waste disposal costs. Assessments on sustainability of the textile and apparel sector as well as benchmark results focused on the environmental impacts of the most commonly used fibres in the fashion industry are given in this study. In addition to these, classification of textile wastes, waste management strategies, methods and practices for textile recycling are presented

Effects of aerobic plus explosive power exercises on bone remodeling and bone mineral density in young men

Objectives: This study aims to examine effects of aerobic jogging and explosive power exercises on body composition, maximal oxygen consumption (MaxVO2), bone mineral density (BMD) and bone turn-over markers: serum bone alkaline phosphatase (BAP), C terminal telopeptide (CTx), Procollagen type I N-terminal propeptide (PINP), in men aged between 20 and 40. Materials and methods: Thirty seven healthy males were divided into exercise group (EG, n = 19) and control group (CG, n = 18). EG completed 10 weeks of outdoor aerobic (jogging at 60-70% maximal heart rate reserve starting from 20 min steadily increasing up to 28 min) and explosive power exercises (in 2-3 sets, with maximum repetitions lasting 15 s), 3 times per week. All measurements were taken before and after the exercise program. BMD was measured via dual energy X-ray absorptiometry (DEXA). Results: Body mass index (p < 0.001) significantly decreased; MaxVO2 (p < 0.001), femur neck (p = 0.036) and total score BMD significantly increased in EG (p = 0.034). BAP and vitamin D increased in both groups (p < 0.001). Conclusion: Performing our outdoor exercise program in spring months might have an important role in the significant increase (9 vs. 22 ng/mL) in mean vitamin D level, which reached above the fracture risk level of 20 ng/mL. © 2018 Turkish Biochemistry Society.
