Abstract

Sheet Glass Industry is one industry that uses 75 % natural gas energy and 25 % electricity. Using the Intergovernmental Panel on Climate Change, IPCC-2006 emission calculation method, the average greenhouses gas (GHG) emissions obtained from the calcination process obtained 112 211 t CO2 yr–1 per plant and an average emission factor (EFkl) of 0.18 CO2 t–1 yr–1 of pull. With the technology of converting heat into electrical energy, residual combustion as flue gases has the potential to be used to produce electrical energy. Referring to the analysis and calculation; one of factories has potential to generate 0.8 MW to 3 MW electric energy. It’s efficiency of 10 % to 40 % so that it can be calculated as a component of GHG emission reductions whose value is 4.6 t CO2 yr–1 to 18.7 t CO2 yr–1 per plant. With this reduction, each of the GHG emission and emission factors per plant dropped to 93 442 t CO2 yr–1 and 0.16 CO2 t-pull–1.

Highlights

Global warming is a term used to describe the gradual increase in the average temperature of the earth's atmosphere and oceans, the value of 0.74 °C ± 0.18 °C (1.33 °F ± 0.32 °F) over the last 100 yr
The industrial sector provides energy consumption which varies by region, according to differences in industrial output, energy intensity, and industry composition [2]
Indonesia's commitment at COP-21 in Paris to reduce greenhouses gas (GHG) emissions by 29 % in 2030 by its own efforts (CM1) or by 41 % with international assistance (CM2) as outlined in the Nationally Determined Contribution (NDC) document [4]. This momentum is the basis for changing the target for GHG emission reductions in Indonesia by 26 % in 2020

Summary

Introduction

Global warming is a term used to describe the gradual increase in the average temperature of the earth's atmosphere and oceans, the value of 0.74 °C ± 0.18 °C (1.33 °F ± 0.32 °F) over the last 100 yr. Increasing the amount of carbon dioxide and other greenhouse gases released by burning fossil fuels, land clearing, agriculture, and other human activities, is believed to be the main source of global warming that has occurred over the past 50 yr. The Intergovernmental Panel on Climate Change (IPCC) concluded that, most of the increase in global average temperatures since the mid-20th century was most likely due to increased concentrations of greenhouse gases (GHGs) due to human activities [1]. Companies can reduce energy consumption in all ways, including improving industrial sector processes to optimize energy use and minimize energy losses, increase the use of cogeneration, and recycle materials and types of fuel to reduce costs and increase efficiency. The biggest energy consumption is the transportation sector by 43.89 % followed by residential / household 16.62 %, commercial 5.8 % and others. Based on the type of energy used, petroleum is still the largest portion of 43.7 % followed by electricity 19.9 %, natural gas 15.3 %, coal 9.6 %, LPG 8.5 % and biofuels 2.97 % [3]
