The purpose this study was to analyze the factors related to the disposal behavior of college students in recycling resources. Recycling resources were classified into four categories: paper, glass, cans and plastic. The data used this study were collected through questionnaire on 420 college students living in Jeju island. The data were analyzed by using SPSS WIN program and the methods of frequency, average, standard deviation, percentage, internal consistency method, t-test, one-way ANOVA, and Scheffe's multiple range tests. The study results can be summarized as follows. Disposal behavior of paper was influenced by pocket money, of glass by sex and housing type, and of cans by housing type. Mother's education level was related to the disposal behavior of college students in recycling resources. In addition, the results showed that environment-friendly conscious and purchasing behaviors affected the disposal behavior of college students in recycling the resources of paper, glass, cans and plastic. The environment-friendly consciousness of college students was the most influential factor in the disposal behavior in recycling resources.

Recycling systems are usually designed with pulp quality targets based on cleanliness, or similar property. Achieving other specific fibre properties is rarely a goal of a recycling system, but fibre properties can be modified to suit specific end uses. Recycling line equipment choices impact n fibre properties, but these effects choices impact on fibre properties, but these effects tend to be less well documented than the effects on cleanliness or brightness.

Nowadays, flooding wast is serious problem to mankind and the endeavour for solving waste problem is performed in connection with environmental problem and natural resource problem. In Korea, there are a lot of movements related to reduction of waste, too. As the solution of these problems, recycling is recommanded and many kinds of recycling technique are devised. In America, military has been playing an important role in recycling area for a long time. This paper is the survey of several articles and working papers about America military's recycling research. We investigated the recycling of water, construction and demolition wastes etc. These research results are very important in real field of military. It is considered our military has to prepare this recycling problem and now it's the right time. All of these can be adapted to our military, commercial companies and civilians through some modification. We suggest that our military should cope with recycling problem more deliberately.

The base paper of corrugated board is mainly produced from Korean old corrugated container (KOCC), and thus the recycling rate of KOCC is very high. However, there is a problem that the pulp quality is very low while the recycling rate of OCC is high. The fines content in KOCC, the main source of the corrugated board, amounts to nearly the half of the total stock, and its formation increases as recycling process repeats due to the hornification of fiber. There have been attempts to improve the drainage property of OCC by increasing the headbox concentration of the paper machine or by applying drainage-promoting polymer additives. However, these conventional methods have problems of weakened paper strength and lowered converting fitness caused by paper formation hindrance. The strength of linerboard could not be increased in case KOCC is used, because hornified OCC pulp can-not be sufficiently refined due to the lowered drainage property caused by fines formation. We studied about a new technique consisting of froth-flotation for fractionating pulp stock into a long fiber portion and fines fraction. This study will be developed in order to enhance the drainage and strength properties of a recycled OCC pulp by selective treatment of flocculant on fractionated OCC Fines.
