Abstract

The cement industry is one of the largest contributors to greenhouse gas emissions, particularly carbon dioxide (CO₂), which significantly impacts global climate change. Reducing CO₂ emissions in cement production is a crucial challenge for achieving environmental sustainability. One potential solution is the use of Refuse-Derived Fuel (RDF) as an alternative fuel in cement kilns. RDF has a high calorific value and can partially replace fossil fuels like coal, leading to a significant reduction in emissions.
This study evaluates CO₂ emissions reduction in the cement production process at PT Indocement by utilizing Alternative Fuel (AF) containing RDF technology. The calculation of CO2 emission using the IPCC 2006 Guidelines, and the resulting emissions are projected using linear regression. A comparative analysis was conducted by obtaining CO₂ emissions to assess the emission reduction achieved through the use of RDF technology. The study evaluated the required percentage of AF to meet the company's emission reduction targets or alternative scenarios. This study analyzes the trend of greenhouse gas emissions resulting from fuel combustion and cement production at Plant 11 and Plant 14 during the period 2020 to 2024. The study results show that emissions from fuel combustion in Plant 11 increased from 199,783 tons CO₂ in 2020 to 554.477 tons CO₂ in 2024. At Plant 14, emissions increased significantly from 404,518 tons CO₂ in 2020 to 447,501 tons CO₂ in 2022. The increase in emissions was caused by non-biomass fuels not passing through optimal pre-treatment, while further reductions were driven by the transition to environmentally friendly fuels such as biomass fuels. Emissions from the cement production process at both plants showed fluctuations, with Plant 11 decreasing from 71,275 to 67,405 tons of CO₂ eq/ton of cement eq, and Plant 14 from 139,825 to 117,948 tons of CO₂ eq/ton of cement eq during the 2020-2024 period. To achieve the emission intensity target of 0,490 tons CO₂ eq/ton cement by 2030, it is necessary to increase the use of carbon-neutral biomass-based alternative fuels (AF) in the new scenario by 42%, is required in the new scenario with emission intensities of 0.486 and 0.493 tons CO₂ eq/ton of cement eq. This strategy not only reduces emission intensity but also improves energy efficiency and supports the sustainability of the cement industry.

Industri semen merupakan salah satu kontributor terbesar emisi gas rumah kaca, terutama karbon dioksida (CO₂), yang berdampak signifikan terhadap perubahan iklim global. Mengurangi emisi CO₂ dalam produksi semen merupakan tantangan krusial untuk mencapai keberlanjutan lingkungan. Salah satu solusi potensial adalah penggunaan Bahan Bakar dari Sampah (RDF) sebagai bahan bakar alternatif dalam tungku semen. RDF memiliki nilai kalor yang tinggi dan dapat menggantikan sebagian bahan bakar fosil seperti batu bara, sehingga menghasilkan pengurangan emisi yang signifikan.
Studi ini mengevaluasi pengurangan emisi CO₂ pada produksi semen di PT Indocement melalui pemanfaatan bahan bakar alternatif (AF) berbasis RDF. Emisi CO₂ dihitung menggunakan Pedoman IPCC 2006 dan emisi yang dihasilkan diproyeksikan mengunakan regresi linier. Analisis perbandingan dilakukan dengan memperoleh emisi CO2 untuk menilai pengurangan emisi yang dicapai melalui penggunaan teknologi RDF. Studi ini juga mengevaluasi persentase AF yang diperlukan untuk memenuhi target pengurangan emisi perusahaan atau skenario alternatif. Studi ini menganalisis tren emisi gas rumah kaca yang dihasilkan dari pembakaran bahan bakar dan produksi semen di Plant 11 dan Plant 14 selama periode 2020 hingga 2024. Hasil studi menunjukkan bahwa emisi dari pembakaran bahan bakar di Plant 11 meningkat dari 199.783 ton CO₂ pada 2020 menjadi 554.477 ton CO₂ pada 2024. Di Plant 14, emisi meningkat secara signifikan dari 404.518 ton CO₂ pada 2020 menjadi 447.501 ton CO₂ pada 2022. Peningkatan emisi disebabkan oleh bahan bakar non-biomassa tidak melalui pre-treatment yang optimal, sedangkan penurunannya didorong oleh transisi ke bahan bakar biomassa yang lebih ramah lingkungan. Emisi dari proses produksi semen di kedua pabrik menunjukkan fluktuasi, dengan Plant 11 menurun dari 71.275 menjadi 67.405 ton CO₂ eq/ton semen eq, dan Plant 14 dari 139.825 menjadi 117.948 ton CO₂ eq/ton semen eq selama periode 2020-2024. Pencapaian target intensitas emisi 0,490 ton CO₂ eq/ton semen pada tahun 2030, diperlukan peningkatan penggunaan AF berbasis biomassa yang netral karbon (AF) sebesar 42% dalam skenario baru dengan intesitas emisi 0,486 dan 0,493 Ton CO2 eq/ton sement eq. Strategi ini tidak hanya mengurangi intensitas emisi tetapi juga meningkatkan efisiensi energi dan mendukung keberlanjutan industri semen.
