چکیده مقاله :
Poultry industry is an important production system due to providing remarkable portion of the human food and protein needs. Considering the necessity of environmental protection, the amount of environmental impacts of a turkey production unit in Iran was determined using life cycle assessment method. The required information were collected through questionnaires and interviews with farm owners. In this research, the system boundary was poultry farm gate and functional unit was considered as onetonne of turkey meat. The amount of indicators including abiotic depletion, abiotic depletion (fossil fuels), global warming, ozone layer depletion, human toxicity, fresh water aquatic ecotoxicity, marine aquatic ecotoxicity, terrestrial ecotoxicity, photochemical oxidation, acidification potential and eutrophication potential were found to be 1.61 kg Sb eq, 20.19 MJ, 3.63 kg CO2 eq, 1.90 kg CFC -11 eq, 67.60 kg 1.4 DB eq, 4.55 kg 1.4 DB eq, 1.04 kg 1.4 DB eq, 1.17 kg 1.4 DB eq, 0.0005 kg C2H4 eq, 0.024 kg SO2 eq and 0.0094 kg PO4 eq, respectively. The results showed that the feed input has the highest emissions in comparison with other inputs.
صنعت طیور به خاطر تأمین سهم قابل توجهی از نیاز غذایی و پروتئینی بشر یکی از بخشهای مهم تولیدی میباشد. با توجه به ضرورت حفظ محیط زیست، میزان انتشار آلایندهها در یک واحد تولیدی بوقلمون در ایران با استفاده از روش ارزیابی چرخه حیات مورد بررسی قرار گرفت. اطلاعات مورد نیاز از طریق پرسشنامه و مصاحبه حضوری با مرغدار جمعآوری شد. در این روش مرز سامانه دروازه واحد پرورش و واحد عملکردی یک تن گوشت بوقلمون در نظرگرفته شد. انتشار آلایندهها مربوط به نهادهها و ستادههای واحد پرورش تعیین گردید. مقادیر شاخصهای زیستمحیطی شامل: تخلیه منابع زمینی، تخلیه منابع فسیلی، گرمایش جهانی، تخلیه لایه اوزن، سمیت انسانی، سمیت آبهای سطحی، سمیت آبهای آزاد، سمیت زمینی، اکسیداسیون فوتوشیمیایی، پتانسیل اسیدی شدن و یوتریفیکاسیون به ترتیب برابر kg Sb eq 61/1، MJ 19/20، kg CO2 eq 63/3، kg CFC -11 eq 90/1، kg 1.4 DB eq 60/67، kg 1.4 DB eq 55/4، kg 1.4 DB eq 04/1، kg 1.4 DB eq 17/1،kg C2H4 eq 0005/0، kg SO2 eq 024/0 و kg PO4 eq 0094/0 بدست آمد. نتایج نشان داد که نهاده خوراک بیشترین آلایندگی را در بین نهادههای مصرفی داشت.
