“…The Life Cycle Assessment (LCA) is one method that can be used in calculating the impact of greenhouse gas emissions produced by a process or product (Sharma et al, 2018;Potter & Röös, 2021). LCA is carried out by quantifying the use of resources involved and carbon dioxide emissions produced by a system that is limited by a system boundary (Badan Standardisasi Nasional, 2016;Badan Standardisasi Nasional, 2017).…”

ABSTRAK Tahu merupakan salah satu sumber protein dengan permintaan yang tinggi di Indonesia. Saat ini beberapa industri tahu telah menggunakan peralatan-peralatan berbahan dasar stainless steel. Kondisi ini menunjukkan keseriusan industri tahu untuk membuat produk tahu yang higienis. Namun, produk tahu yang higienis saja tidaklah cukup. Persaingan pasar global menuntut sebuah produk tidak hanya memperhatikan kualitas, namun juga menjadi produk yang ramah lingkungan dengan ditandai oleh nilai emisi CO2 yang rendah. Sejalan dengan kondisi tersebut, maka studi terkait dengan perhitungan emisi CO2 yang dihasilkan oleh sebuah produk menjadi hal yang perlu diutamakan. Pada studi ini dilakukan penelitian estimasi emisi CO2 yang dihasilkan dari 1 kg tahu dengan menggunakan metode LCA dan menerapkan batasan sistem from cradle to gate, yakni penghitungan emisi Gas Rumah Kaca (GRK) dihitung dari penanaman kedelai hingga menjadi 1 kg produk tahu. Studi kasus dilakukan pada 3 industri tahu dan diketahui bahwa emisi GRK yang dihasilkan per 1 kg tahu berada pada rentang 0,35–0,5 kg CO2 eq. Faktor utama penyumbang emisi CO2 berasal dari air limbah hasil dari proses produksi, diikuti budidaya kedelai dan transportasi bahan baku kedelai dari perkebunan menuju ke industri. Hasil penelitian ini memberikan rekomendasi kepada industri tahu untuk mengurangi emisi CO2 yang dihasilkan dari limbah cair proses produksi tahu. Alternatif pengolahan limbah cair yakni dengan mengolah air limbah menggunakan sistem anaerobik guna menghasilkan biogas yang digunakan untuk kebutuhan memasak. Kata kunci: Kedelai, Tahu, LCA, Emisi GRK, Limbah cair ABSTRACT Tofu is one of the protein sources with high demand in Indonesia. Currently, several tofu industries have used stainless steel-based equipment. This condition shows the seriousness of the tofu industry to make hygienic tofu products. However, hygienic tofu products are not enough. The global market competition required the products to take notice not only of their quality but also of environmentally-friendly products characterized by a low value of CO2 emission. In accordance with the condition, studies related to calculating CO2 emissions resulting from a product are necessary. In this study, we conducted research on the estimation of CO2 emissions resulting from 1 kg of tofu using the LCA method and applying the system boundary from cradle to gate, in which greenhouse gas (GHG) emissions were calculated from soybeans plantation to 1 kg of tofu products. Case studies were conducted on three tofu industries, and it was found that the GHG emissions produced per 1 kg of tofu were in the range of 0.35–0.5 kg CO2 eq. Three main factors contribute to CO2 emissions, i.e., wastewater, soybean cultivation, and soybean transportation from plantation area to industry. Therefore, this study recommends the tofu industry reduce CO2 emissions resulting from wastewater. The alternative is to treat wastewater using an anaerobic system to produce biogas for cooking purposes. Keywords: Soybeans, Tofu, Life Cycle Assessment (LCA), GHG emissions, Wastewater

“…The life cycle assessment approach takes into account many logistical activities like packaging and distribution plus the standard product design and manufacturing processes (Zanjirani et al, 2009). The use of LCA to evaluate the sustainability of manufacturing processes and products can be found in the literature (Durgesh et al, 2011;Nigri et al, 2014;Raymond, 2013;Sharma et al, 2018). LCA technique includes all the environmental impacts arising out of a product through its life cycle from extraction of raw materials, production, use phase till disposal (Kumar et al, 2020).…”

A medicine can be administered in varied dosage forms which are having different environmental impacts. Two dosage forms of paracetamol (tablet and syrup) have the same function but are prepared and packaged differently, meaning that the environmental impacts arising out of their production will be of different magnitude. This study utilizes the life cycle assessment technique to find and compare the environmental impacts of two dosage forms of the paracetamol. Life cycle assessment software 'GaBi' v 8.0 has been utilized to carry out this study. Midpoint and endpoint impact assessment methods from 'ReCiPe' impact assessment method are used to carry out the life cycle impact assessment. The midpoint impact assessment results show that syrup production has 90% contribution in climate change impact category and more than 50% environment impact in fine particulate matter formation, fossil depletion, freshwater consumption, freshwater eutrophication, freshwater ecotoxicity, ionizing radiation, photochemical ozone formation, stratospheric ozone depletion, and terrestrial ecotoxicity midpoint impact categories. Tablet production has major impacts in 3 midpoint impact categories that are human toxicity, ionizing radiation, and metal depletion. Syrup production has major impacts (more than 70%) in 8 out of the 11 endpoint impact categories considered, while tablet production has a major impact in 3 impact categories that are human toxicity and ionizing radiation endpoint impact categories. Syrup production has a visibly higher impact in more number of midpoint as well as endpoint impact categories considered. The environmental hotspot is, however, dependent on the individual impact categories. The results of the study add to the existing knowledge of environmental sustainability assessment in the pharmaceutical sector and will benefit the environmental managers to better manage the environmental sustainability of pharmaceutical products.
