Assessing the Carbon Footprint of a Product: A Case Study : Underground Electrical Cable Manhole Construction for Pipe Jacking

Abstract

      This study aims to assess the carbon footprint of the product, specifically focusing on the case study of underground electrical cable manhole construction for pipe jacking. By employing the principles of carbon footprint assessment for the product evaluation. It is quantitative research. The study of environmental impacts arising from the construction of underground electrical cable ducts and cable systems over one kilometer. Using the Life Cycle Assessment (LCA) method in the Business to Business (B2B) format.  The study found that the construction of underground electrical cable ducts using Pipe Jacking results in greenhouse gas emissions equivalent to 2,761,673.56 kgCO₂e/km. By dividing the work into three main activities. In assessing the equivalent carbon dioxide emissions released during the pipe jacking process, the highest value recorded is 1,412,814.5 kgCO₂e/km. 2) Underground electrical cable laying is equal to 918,474.324 kgCO2e/km. 3) The manhole installation is equal to 430,384.737 kgCO2e/km. Whereas the highest greenhouse gas emissions release is from the pipe jacking activity, accounting for 51.15% of the total. Due to the extensive use of cement concrete and the transportation of concrete pipes for Pipe Jacking over long distances, up to 50 kilometers, from the casting facility in Pathum Thani province.
