Estimating the Additional Greenhouse Gas Emissions in Korea: Focused on Demolition of Asbestos Containing Materials in Building

View Article: PubMed Central - PubMed

ABSTRACT

When asbestos containing materials (ACM) must be removed from the building before demolition, additional greenhouse gas (GHG) emissions are generated. However, precedent studies have not considered the removal of ACM from the building. The present study aimed to develop a model for estimating GHG emissions created by the ACM removal processes, specifically the removal of asbestos cement slates (ACS). The second objective was to use the new model to predict the total GHG emission produced by ACM removal in the entire country of Korea. First, an input-equipment inventory was established for each step of the ACS removal process. Second, an energy consumption database for each equipment type was established. Third, the total GHG emission contributed by each step of the process was calculated. The GHG emissions generated from the 1,142,688 ACS-containing buildings in Korea was estimated to total 23,778 tonCO2eq to 132,141 tonCO2eq. This study was meaningful in that the emissions generated by ACS removal have not been studied before. Furthermore, the study deals with additional problems that can be triggered by the presence of asbestos in building materials. The method provided in this study is expected to contribute greatly to the calculation of GHG emissions caused by ACM worldwide.

Mentions: Administrative district of Korea is divided into metropolitan governing units and local governing units. The former are roughly classified into seventeen units (i.e., one special city, six metropolitan cities, one metropolitan autonomous city and nine provinces), and then further into 163 local governing units (cities and countries). The methods for the reclamation and disposal of ACM are currently under development [39]; however, the Wastes Control Act of Korea defines ACM as designated waste containing hazardous materials, which should be buried in places other than general landfills. As of 2013, a total of five locations existed specifically for burying ACM [40]. Additionally, each landfill contains a designated area for ACM burial. The majority of the ACM being buried are ACS. Figure 3 shows the local governing units in Korea, and the locations of ACS landfills.
