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: Building demolition can lead to emission of dust (e.g., hazardous fiber) into the environment [27]. Asbestos fibers can also be released into the environment during the removal process, causing the same deleterious environmental and health effects that the removal was commissioned to curb. Most at risk, in this case, is the health of demolition workers and the general public [27]. The EPA’s National Emission Standards for Hazardous Air Pollutants (NESHAP), the Occupational Safety and Health Act (2009), and the Asbestos Safety Management Act (2012) state that all ACM must be removed from buildings in advance of demolition [28,29]. Therefore, the building demolition process generates GHG emissions two-fold—first by the precursory step of ACM removal, and second, by the demolition itself. Because no existing studies have explored this additional GHG emission, the objectives of this study were to (1) develop a model for estimating the additional GHG generated by ACS removal during building demolition and (2) use this model to estimate the total GHG emissions generated by ACS removal in the entire country of Korea. An overview of the methodology is presented as a flow chart in Figure 1. This study is meaningful in that it discusses problems regarding GHG emissions that have thus far not been considered within the building sector. The methodology developed in this study allows the estimation of GHG emissions that were previously not accounted for in GHG modeling. The methodology can be used to produce databases of ACS removal emissions, which can, in turn, inform solutions and policies toward global GHG reduction in the future.
