Abstract Condensation inside marine containers occurs during voyages owing to weather changes. In this study, we define the condensation probability along one of the major routes for container ships between Asia and Europe. First, the inside and outside air conditions were measured on land in Japan, and a correlation analysis was conducted to derive their relationship. Second, onboard measurements were conducted for 20,000 twenty-foot equivalent unit (TEU) ships to determine the variation in outside air conditions. Complicated patterns of weather change were observed with changes in latitude, sea area, and season. Third, condensation probability was estimated based on a multi-regression analysis with land and onboard measured data. The maximum condensation probability in westbound or eastbound voyages in winter was found to be approximately 50%. The condensation probability estimation method established in this study can contribute to the quantification of cargo damage risks for the planning of marine container transportation voyages.

In recent years, the state-of-the-art research has been dealing with putting into traffic, withdrawing and freeing the environment from electrical and electronic equipment waste-WEEE. In our country there has been no serious research so far concerning this problem, although current and future members of the European Union (EU) are obligated to conduct WEEE directive based on individual responsibility of each "waste manufacturer". The Ministry of Science and Environmental Protection of Serbia has accepted the financing of scientific research project called "The development of electrical and electronic equipment recycling system". In this paper, statistical estimation method of quantity and diffusion of computer waste (which according to the EU classification, belongs to the third category WEEE-devices for computer and communication technique) in the territory of Serbia is described. The implications of the problem on our country are also presented.
