The Directive on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment commonly referred to as the Restriction of Hazardous Substances Directive or RoHS was adopted in February 2003 by the European Union. The RoHS directive took effect on 1 July 2006, and is required to be enforced and become law in each member state. This directive restricts the use of six hazardous materials in the manufacture of various types of electronic and electrical equipment. It is closely linked with the waste electrical and electronic equipment directive (WEEE) 2002/96/EC which sets collection, recycling and recovery targets for electrical goods and is part of a legislative initiative to solve the problem of huge amounts of toxic e-waste.

유해물질제한지침(RoHS)의 제6조항에 따라 유럽위원회가 지침을 재검토 중이다. 유럽의회는 RoHS 규제에 현 8종의 전기전자 제품군에서 모든 제품으로의 규제 시행 확대와 기존 4종의 중금속과 2종의 난연제 규제에서 브롬계 난연제, 크롬계 난연제, PVC, 유해 플라스틱 첨가제 등의 즉각적 규제를 목표로 하고 있다.

유해물질 제한지침(Restriction of Hazardous Substances Directive)은 유럽연합(EU)에서 시행되며 해로운 물질을 사용한 전자제품이나, 전기기기를 제한하는 지침이다. 일반적으로 RoHS(알오에이치에스)라고 적는다. 2003년 2월에 WEEE(Waste Electrical and Electronic Equipment)에 의해 제정 공포되고 2006년 7월 1일 발효되어 카드뮴, 납, 수은, 6가 크롬, 브롬계 난연제(PBBs, PBDEs)의 사용이 금지되었다. 중국에서도 이와 비슷한 제도 RoHS(일명 China RoHS)를 시행을 하고 있어 유럽에서 정한 6가지 품목과 규제 대상이 아니지만, 과학기기나 의학장비도 중국의 RoHS에는 규제 대상에 포함되어 있다.

Product-based environmental regulations, such as RoHS, REACH, EuP, etc., on electrical and electronic equipments, chemicals, and so on, initiated by the European Union, are becoming a global trend. These regulations can create barriers to trade among nations worldwide and may thereby have a direct impact on the function of internal market. If domestic companies utilize well the international environmental regulations in advance, they will get good opportunity for expanding overseas market. In this paper the current status of countermeasure for overcoming the international environmental regulations in domestic industries was investigated and the future plans were discussed.

LCD televisions and monitors use cold cathode fluorescence lamps (CCFLs) to illuminate the screen. Most CCFLs contain mercury and they have to be carefully handled at the end of their lives as per minimum treatment standards under the Waste Electrical and Electronic Equipment (WEEE) and Restriction of Hazardous Substances (RoHS) directives. CCFLs were carefully separated from mold frames of waste LCD units for primary decontamination of mercury/fluorescent compound mixture using CCFL decontamination system designed and fabricated in the present research. Residual mercury was further removed by employing a pyro-process, where crushed CCFL tubes transferred from primary decontamination process were subject to heat treatment at $550^{\circ}C$ in a box furnace: more than 99% of mercury was removable from waste CCFLs.

Due to many recent activities on enforcement of the intensified environmental regulation such as the policies of curbing the greenhouse gas and the Restriction of Hazardous Substances (RoHS), the usage of Light emitting diode (LED) has been rapidly increased and energy efficient management of LED light system is regarded as an important technology to enhance the energy efficiency. In this paper, we propose an energy-efficient control scheme of LED light, being composed of multiple light sources. The proposed scheme controls the intensity of LED light source to minimize the total intensity while providing the quality of lighting service. The intensity of light is assumed to be proportional to power consumption, thus the objective is to minimize the total power consumption. A linear programming problem is formulated to find the optimal intensity of each light source and procedure to apply the proposed scheme in the real system is suggested. The performance evaluation results elucidate that the proposed scheme achieves over 20% improvement in power consumption of light intensity in comparison with the conventional dimming control scheme.
