Nowadays, countries all over the world are deeply concerned about pollution in the global environment, so they are seeking various ways to adequately disposal of waste. Still, the environmental situation seems to be getting worse and worse. It is evident that such wastes and pollution have been endangering human life nestled in this globe up to the end of the 20th century. We should not, however, tolerate such human misconduct and mal-management of resources any more in the new millenium. For realizing a society that is sustainable for generations to come, it is important to establish a social system for minimizing wastes, promote re-use and recycling, and develop technology for improving recycling efficiencies, including product designs that facil-itate re-use and recycling and innovative technologies for processing wastes. In this paper, reviewing the current status of Korean waste problems, the governmental policy and specific approach for the establishment for recycling society is considered.

Recently efficient recycling of natural resource has been raised many people's interest with global warming issue. This study is focused mainly on main content of automobile recycling regulation and current situation of each nations including EU which is firstly acted. Also we were considering for adequate way to make better resource recycling condition and reduce Environment burden.

This research was performed to use recycling wood fiber from waste MDF as raw materials for manufacturing of interior decorative accessories. Virgin fiber of Pinus rigida for manufacturing MDF and recycling fiber from manufactured MDF with virgin fiber were dyed by using reactive dyes (Bis-monochlorotriazine and Vinyl sulfone type), vat dyes (Anthraquinone type), direct dyes (Diazo type) such as red, yellow and blue, and natural dyes using gardenia or sappan wood, and they were examined to evaluate their dyeing properties and sunlight fastness. The hue of virgin fiber and recycling fiber were 4.2YR, and 4.4YR, respectively, which showed red-yellowish color. The recycling fiber looked a little darker than the virgin fiber, where $L^*$ values of the recycling fiber showed a little lower. Reactive, vat and direct dyes dyed well both the virgin and recycling fibers. The recycling fiber showed a little higher values of colour yield and a little lower in $L^*$, but it seemed that there was no significant difference. The Hue values of the recycling fiber and the virgin fiber dyed with sappan wood were 4.4YR and 4.0YR, showing no difference between/after dyeing. However the Hue values of the recycling fiber and the virgin fiber dyed with gardenia were 7.4YR and 6.9YR, respectively. Those values were much higher than the values of the fibers dyed with other chemical dyes. But the fibers dyed with gardenia showed poor sunlight fastness.

According to the EPA in Taiwan report, 9.05 million metric tons of solid wastes were generated in 1999, and the waste glass was accounted of 4.95 percent. However, with the increasing tonnage of disposal cost and existing disposal sites are reaching full capacity, recycling is currently accepted as a sustainable approach to waste management. Therefore, it's essential and urgent that the government in Taiwan establish the recycling and recovery framework for the minimization of the solid waste, reduction of materials and energy consumption, and the encouragement for the reuse, recycle and recovery development. To achieve this Boal, Taiwan has been strived for a long period of time in waste glass recovery and recycle. Waste glass, unlike other kinds of resource waste, is 100% recyclable. The EPA in Taiwan now center on a lot of different kinds of waste glass, such as glass container, flat glass, CRT glass, windshields glass, fluorescent lamps, and waste pesticide glass container. This article will focus on the framework of the recycling market access, and also try to provide some strategies to improve waste glass recycling efficiently.
