Environmental Considerations in Aircraft Manufacturing Industry Through the Example of Boeing Andairbus Companies
59-66Views:111Aircraft manufacturing industry has developed dynamically in the last decades. Reinforced polymers have become the most dominant raw materials, while the recycling rate of the generated industrial waste has also increased. The fuel efficiency of the engines has increased, and the emitted CO2 per capita has significantly fallen. However, the environmental impact of the aircraft manufacturing industry seems to reach a permanent level. In this study, we have analyzed the environmental impact and the environmental considerations of the aircraft manufacturing industry through the examples of Boeing and Airbus companies. Our goal was to determine the relation between industrial growth and the environmental impact, particularly to the potential innovations.

Utilization of grinding dross remained from production process in order to minimize waste and save costs
18-25Views:101It is i mportant to reuse wastes from production process particulary. In the course of metal roughing grinding dross comes off. Its oil content is high enough to treat i t wi th piston briquette machinery and by this methode part of this oil can be retrievable and returned to production. By means of making a ma terial balance I determined how much effective the machinery has to be to work the dross and its payback was also calculated.

Assessment of Mycotoxin Contamination of Foods
90-96Views:184According to RASFF reports, in the present, pathogenic microorganisms, pesticide residues and mycotoxins are the most frequent food contaminants. In 2014, 12% of the total notifications were caused by mycotoxin contamination. In this study we have analyzed the RASFF notifications that are related to the mycotoxin contaminations. It can be stated that aflatoxin is responsible for 90% of the total mycotoxin notifications, and the total notification number has decrease by 40% since 2004. However the number of oc hratoxin-A notifications are slowly increasing. Aflatoxin was mainly detected in nuts and nut products and oil seeds, especially groundnuts, while ochratoxin-A was detected in fruits (more than 85% in figs) and spices. The number of deoxynivalenol and fumonisin notifications were significantly less, however some appear every year for cereals and bakery products, especially corn and wheat. Zearalenone and patulin were detected only in 16 and 18 cases but 22% of the patulin notifications are related to baby food, so the tracking of patulin is really important.
