초록

Environmental concerns regarding mercury-containing fluorescent lamps have been raised in many countries, especially after International Minamata Convention on Mercury in 2014. Improper management and disposal of the waste such as landfilling and incineration may pose serious threats to the environment and human health. In Korea, mercury-containing lamps have been regulated by the expanded producer responsibility (EPR) system since 2004. However, only less than 30% of the lamps sold to consumers has been collected by municipalities. In order to provide additional measures related to proper management of fluorescent lamps, there is a need for a quantitative material flow study by life cycle stage. In this study, material flow analysis was conducted by collecting relevant data from literature review, available statistics, and field site visits to lamp recycling facilities. According to the results of this study, approximately 150 million units of fluorescent lamps were put on the market in 2013, while 36.9 million units of the lamps were recycled mainly from households in the year. It is estimated that approximately 3.5 million units and 2.3 million units of lamps in disposal bags are disposed and treated in landfills and incineration facilities, respectively. This study also found that there were significant amounts of uncollected lamps that were present in industrial sectors. The material flow of the industrial sectors are largely unknown and not properly regulated by government. Based on the mass flow of mercury in lamps, 1.6ton of mercury in lamps came into consumer markets in 2013. Approximately 407 kg of mercury was collected by the recycling process at the fluorescent lamps recycling facility. The mercury disposed in landfills and treated in incinerators were found to be 38.3kg and 25.5kg, respectively. Further study may be warranted to focus the material and mercury flow of lamps in industrial sectors in order to accurately determine the final destination and disposal of such waste in the environment because there are very few available statistical data regarding distribution flow and treatment of lamps in the sectors.
