| Summary: | The use of coal as an energy source will still reach 25% by 2050 according to
Presidential Regulation No. 22 Year 2017. This will make the coal mining process
continue so that many companies, such as PT Pamapersada Nusantara as the largest
coal mining contractor in Indonesia, want to know the environmental impact they
produce. This life cycle assessment analysis has a functional unit of 1 ton of coal. This
analysis has a scope of topsoil removal, overburden removal, coal getting, coal hauling
to port, and mining support with impact factors being acidification potential,
eutrophication potential, global warming potential, and photochemical ozone creation
potential. The main hotspot of mining activities is in the OB removal process with an
acidification potential value of 0.036 kg SO? eq/ton coal or 52.32%, eutrophication
potential value of 0.0032 kg PO? eq/ton coal or 46.99%, global warming potential
value of 5.23 kg CO? eq/ton coal or 52.57%, and photochemical ozone creation
potential value of 0.000029 gr C?H? eq/ton coal or 47.99%. This is due to the large use
of B35 fuel and lubricants in OB removal. The recommendation to reduce the
environmental impact factor is electrification which covers 9.81% of the company's
revenue and has a return on investment of around 2.61% per year. |
