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.

Demolition process of building and boundary of this study: (1) preliminary survey; (2) preliminary work; (3) ACS dismantlement and removal; (4) disposal and cleaning; (5) loading and exporting; and (6) transportation. If the result of Step 1 concludes that the building is ACM-free, the ACS removal process can be omitted, and the demolition can commence immediately.

If the result of Step 1 concludes that the building is ACM-free, the ACS removal process can be omitted, and the demolition can commence immediately.

Mentions: It is stated by the Asbestos Safety Management Act (2012) that when demolishing a building (including remodeling), the inclusion of ACM must be surveyed in advance [29]. As a consequence, if the building contains ACM, the ACM must be removed before demolition [29]. Therefore, compared with the demolition of ACM-free buildings, additional GHG emissions occur during demolition of a building containing ACM. These extra emissions are generated by the electricity and fuel consumption of equipment used in the removal and transportation of the ACM prior to demolition. Therefore, the scope of this study was set as the entire ACS removal process of a building, from the preliminary survey to the transportation of ACS during the demolition stage. This study has classified the ACS removal process into six steps, based on asbestos-related laws, and results from the literature review [34]. Figure 2 depicts the scope of this study, inclusive of these six steps within the general demolition process of a building and the ACM removal process.
