Indirect Greenhouse Gas (GHG) Energy Emissions (Scope 3) [305-3]
4. Waste Emissions
Domestic waste is one of the sources of greenhouse gas emissions for Pupuk Kaltim. Residual waste that cannot be reused is delivered to the Final Disposal Site (TPA) which utilizes a sanitary landfill system. This waste includes residual food waste and paper waste. Both types of waste generate gas emissions annually for a certain period. During the accumulation of domestic waste in the landfill, decomposed waste releases methane gas, which accumulates in the atmosphere.
To reduce the amount of waste sent to the Final Disposal Site, Pupuk Kaltim implements the 3R (Reuse, Reduce, Recycle) efforts. Among these efforts include processing garden waste into compost, recycling used sacks for reuse in the production process, and other waste with commercial value is handed over to waste banks for recycling.
Waste Emissions
CO2 Emission Load = Emission Fraction (%) x Emission Potential (ton CO2e/ton of waste) x Amount of Waste(tons)
Keterangan:
a. Fraksi Emisi : Persen emisi yang dikeluarkan sampah selama masa penumpukan setiap tahunnya
b. otensi Emisi : Potensi pengeluaran emisi yang dikeluarkan per jumlah sampah sesuai dengan jenis sampah yang dihitung
c. Jumlah sampah: Berat masing-masing jenis sampah Dengan,
• Potensi emisi sampah kayu = 2,890 t CO2/t sampah
• Potensi emisi sampah kertas = 2,688 t CO2e/t sampah
• Potensi emisi sampah sisa makanan = 1,008 t CO2e/t sampah
• Potensi emisi sampah kain = 1,613 t CO2e/t sampah
• Potensi emisi sampah sampah taman = 1,344 t CO2e/t sampah
• Potensi emisi sampah sampah lain = 0 t CO2/t sampah 5. Emisi Penggunaan Urea
Penggunaan urea pada tanah dalam proses pemupukan mengakibatkan pelepasan kandungan CO2 yang tersimpan dalam produk pada saat proses produksi. Perhitungan pelepasan emisi GRK dari aktivitas penggunaan pupuk oleh konsumen, menggunakan data mentah berupa data penjualan Pupuk Urea dan NPK Pupuk Kaltim. Perhitungan dilakukan dengan mengalikan berat total urea dengan faktor emisi sehingga didapatkan jumlah emisi CO2-C. Jumlah CO2-C ini kemudian dikalikan dengan 44/12 untuk dikonversikan menjadi emisi CO2. Berikut merupakan uraian emisi gas rumah kaca yang dihasilkan dari penggunaan produk pupuk oleh petani pada tahun 2023:

Explanation:
a. Emission Fraction: Percentage of emissions released by waste during the accumulation period each year b. Emission Potential: Potential emission release per amount
of waste according to the type of waste calculated c. Amount of Waste: Weight of each type of waste
With,
• Wood waste emission potential = 2,890 t CO2e/ton of waste
• Paper waste emission potential = 2,688 t CO2e/ton of waste
• Food waste emission potential = 1,008 t CO2e/ton of waste
• Fabric waste emission potential = 1,613 t CO2e/ton of waste
• Garden waste emission potential = 1,344 t CO2e/ton of waste
• Other waste emission potential = 0 t CO2e/ton of waste 5. Urea Usage Emissions
The use of urea in soil during fertilization processes results in the release of stored CO2 content in the product during the production process. The calculation of greenhouse gas emissions from the use of fertilizer by consumers utilizes raw data such as sales data of Urea and NPK fertilizers from Pupuk Kaltim. The calculation is performed by multiplying the total weight of urea by the emission factor to obtain the amount of CO2-C emissions.
This quantity of CO2-C is then multiplied by 44/12 to convert it into CO2 emissions. Below is the description of greenhouse gas emissions resulting from the use of fertilizer products by farmers in the year 2023:
Penghitungan Emisi Pemakaian Urea
a. Beban emisi CO2 = Jumlah urea x Faktor emisi b. Faktor emisi CO2 = 0,20 ton C/ton urea Penghitungan Emisi NPK
a. Beban emisi CO2 = Jumlah urea dalam produk NPK (ton) x Faktor emisi (ton C/ton urea) b. Faktor emisi CO2 = 0,20 ton C/ton urea
Intensitas Emisi Gas Rumah Kaca
[SEOJK F.11]Intensitas gas rumah kaca Pupuk Kaltim dihitung dengan cara membagi emisi dari scope 1 dan 2 dengan jumlah produk Pupuk Kaltim. Intensitas gas rumah kaca Pupuk Kaltim adalah sebesar 0.71 ton CO2 eq/ton produk.
Scope 3 tidak dimasukkan ke perhitungan intensitas karena tidak berhubungan langsung dengan proses produksi. Gas yang diperhitungkan dalam kalkulasi yaitu CO2, CH4, N2O, HFC, dan PFC.
Pembagi (dedominator) untuk menghitung intensitas emisi gas rumah kaca yaitu jumlah dari produk urea, ammonia, dan NPK pada tahun 2023. [305-1, 305-4]
Pupuk Kaltim memiliki 49 (2022: 46) program pengurangan emisi Gas Rumah Kaca, terdiri dari program pengurangan diproses produksi dan fasilitas penunjang (list program pengurangan emisi GRK ada di tabel di bawah). Hal ini memiliki kontribusi yang besar untuk menghambat laju pemanasan global.
Selain program pada proses produksi, terdapat program pengurangan emisi gas rumah kaca dari fasilitas penunjang seperti perbaikan sistem tata udara, tata cahaya, dan elektromekanik serta dari penggunaan biodiesel dan program pengomposan daun sisa pembersihan area Pupuk Kaltim.
Pupuk Kaltim juga memiliki program Comdev yang bisa mengurangi emisi gas rumah kaca yaitu penggunaan solar cell, pengelolaan sampah organik dengan Black Soldier Fly, dan pengolahan sampah organik cangkang kepiting menjadi pupuk Chitosan cair.
Seluruh inisiatif tersebut menghasilkan total volume pengurangan emisi GRK sebesar sebesar 866,068.23 ton CO2 eq (2022: 973,055.35 ton CO2 eq) atau sekitar 14% (2022: 11,07%) dari total beban emisi Perusahaan (scope 1, 2, dan 3) pada tahun 2023. [305-5] [SEOJK B.2.b]
Calculation of Urea Use Emissions
a. CO2 emission load = Amount of urea x Emission factor b. CO2 emission factor = 0.20 ton C/ton urea
NPK Emission Calculation
a. CO2 emission load = Amount of urea in NPK products (tons) x Emission factor (tons C/tons urea) b. CO2 emission factor = 0.20 ton C/ton urea
Greenhouse Gas Emission Intensity
[SEOJK F.11]The greenhouse gas intensity of Pupuk Kaltim is calculated by dividing the emissions from scope 1 and 2 by the total amount of Pupuk Kaltim products. The greenhouse gas intensity of Pupuk Kaltim is 0.71 tons CO2eq/ton of product.
Scope 3 emissions are not included in the intensity calculation as they are not directly related to the production process. The gases considered in the calculation are CO2, CH4, N2O, HFC, and PFC.
The denominator used to calculate the intensity of greenhouse gas emissions is the total number of urea, ammonia, and NPK products in the year 2023. [305-1, 305-4]
Pupuk Kaltim has 49 (2022: 46) greenhouse gas emission reduction programs, consisting of reduction programs in the production process and supporting facilities (the list of greenhouse gas emission reduction programs is provided in the table below). This significantly contributes to slowing down the rate of global warming.
In addition to programs in the production process, there are greenhouse gas emission reduction programs from supporting facilities such as improving air conditioning, lighting, and electromechanical systems as well as using biodiesel and composting programs for cleaning waste leaves in the Pupuk Kaltim area.
Pupuk Kaltim also has Comdev programs that can reduce greenhouse gas emissions, such as the use of solar cells, organic waste management with Black Soldier Fly, and the processing of organic waste crab shells into liquid Chitosan fertilizer.
All of these initiatives result in a total volume of greenhouse gas emission reduction of 866,068.23 tons CO2eq (2022: 973,055.35 tons CO2eq) or approximately 14% (2022: 11.07%) of the total company emissions burden (scopes 1, 2, and 3) in 2023. [305-5] [SEOJK B.2.b]
