Pupuk urea adalah merupakan salah satu jenis pupuk yang paling banyak digunakan oleh petani di Indonesia. Total penggunaan pupuk urea selama tahun 2018 yang tercatat pada Kementerian Perindustrian Indonesia adalah sejumlah 6,27 Juta ton atau mengalami peningkatan 5% dari tahun sebelumnya. Salah satu pabrik yang menghasilkan pupuk urea adalah PT Pupuk Kujang di Cikampek Jawa Barat. Tujuan dari studi ini adalah untuk mengidentifikasi dampak lingkungan potensial yang dihasilkan dari produksi 50 Kg pupuk urea. Metode yang digunakan dalam kajian dampak daur hidup (Life Cycle Impact Assessment) adalah CML-IA dengan 11(sebelas) parameter yaitu abiotic depletion dan abiotic depletion (fossil fuel), global warming (GWP100), ozone layer depletion, human toxicity, fresh water dan marine aquatic ecotoxicity, terrestrial ecotoxicity, photochemical oxidation, acidification, dan eutrophication,  Adapun batasan sistem menggunakancradle to grave yang memperhitungakn bahan dasar, proses produksi, transportasi dan pengelolaan limbah (karung bekas pupuk). Dari hasil analisa didapatkan bahwa proses produksi memberikan kontribusi dampak paling besar dibandingkan dengan pengelolaan limbah sisa karung (landfill). Proses produksi memberikan kontribusi terhadap dampak potensial lingkungan pada kisaran 99,14 – 100 persen dari total dampak yang di hasilkan. Sebagai tambahan bahwa dampak yang ditimbulkan pada proses di pabrik ammonia akan memberikan kontribusi lebih besar pada kisaran 22-37 persen lebih besar dibandingkan dengan proses di pabrik urea.Dari hasil analisa dengan memanfaatkan grafik jaringan (networking graph) pada program SimaPro juga menunjukkan bahwa environmental hotspotsdari daur hidup pupuk urea disebabkan oleh penggunaan gas alam, katalis molybdenum, penggunaan listrik dari Perusahaan Listrik Negara (PLN), penggunaan polypropylene dalam material karung, dan transportasi. Dengan mempertimbangan environmental hotspot maka tindakan perbaikan berkelanjutan perlu dilakukan baik berupa  audit energi maupun pengelolaan penggunaan katalis.

The article characterizes selected issues related to the method of performing environmental impact analyses. Particular attention was paid to the need for identifying environmental effects associated with the process of shaping beverage bottles. This study concerns the analysis of selected stages of the machine’s life cycle environmental impact in the specific case of the blow molding machine used in the production of bottles. Life cycle assessment analysis was performed using the SimaPro 8.4.0 software (The Dutch Company Pre Consultants). The CML 2 and ReCiPe2016 methods were chosen to interpret the lists of chemical emissions. Impact categories specific to the CML 2 model are: abiotic depletion, acidification, eutrophication, global warming, ozone layer depletion, human toxicity, fresh water aquatic ecotoxicity, marine aquatic ecotoxicity, terrestrial ecotoxicity, and photochemical oxidation. Among all the considered impact categories, marine aquatic ecotoxicity was characterized by the highest level of potential harmful effects occurring during the bottle production process. A new aspect of the research is to provide updated and more detailed geographic data on Polish bottle production.

Although recycled polymers and reinforced polymer composites have been in use for many years there is little information available on their environmental impacts. The goal of the present study is to analyze the environmental impact of new composite materials obtained from the combination of recycled thermoplastics (polypropylene [PP] and polyethylene [PE]) with mineral fillers like talc and with glass fiber. The environmental impact of these composite materials is compared to the impact of virgin PP and PE. The recycled and virgin materials were compared using life cycle assessment method according to their environmental effects. Within the scope of the study, GaBi software was used for Life Cycle Assessment (LCA) analysis. From cradle-to-grave life cycle inventory studies were performed for 1 kg of each of the thermoplastics. Landfilling was considered as reference scenario and compared with filled recycled plastics. A quantitative impact assessment was performed for four environmental impact categories, global warming (GWP) over a hundred years, human toxicity (HTP), abiotic depletion (ADP) and acidification potential (AP) were taken into consideration during LCA. In the comparison of recycled and virgin polymers, it was seen that recycling has lower environmental effect for different impact assessment methods like acidification potential, abiotic depletion, human toxicity and global warming.

Purpose Bioconcrete is widely believed to be environmentally beneficial over conventional concrete. However, the process of bioconcrete production involves several steps, such as waste recovery and treatment, that potentially present significant environmental impacts. Existing life-cycle assessments of bioconcrete are limited in the inventory and impact analysis; therefore, they do not consider all the steps involved in concrete production and the corresponding impacts. The purpose of this study is to extensively study the cradle-to-gate environmental impacts of all the production stages of two most common bioconcrete types (i.e. sludge-based bioconcrete and cement kiln dust-rice husk ash (CKD-RHA) bioconcrete) as opposed to conventional concrete. Design/methodology/approach A cradle-to-gate life-cycle assessment process model is implemented to systematically analyze and quantify the resources consumed and the environmental impacts caused by the production of bioconcrete as opposed to the production of conventional concrete. The impacts analyzed in this assessment include global warming potential, ozone depletion potential, eutrophication, acidification, ecotoxicity, smog, fossil fuel use, human toxicity, particulate air and water consumption. Findings The results indicated that sludge-based bioconcrete had higher levels of global warming potential, eutrophication, acidification, ecotoxicity, fossil fuel use, human toxicity and particulate air than both conventional concrete and CKD-RHA bioconcrete. Originality/value The contribution of this study to the state of knowledge is that it sheds light on the hidden impacts of bioconcrete. The contribution to the state of practice is that the results of this study inform the bioconcrete production designers about the production processes with the highest impact.

STUDI KOMPARASI PENGGUNAAN KUNYIT DENGAN IRADIATOR SEBAGAI PENGAWET TAHU DENGAN PENDEKATAN LIFE CYCLE ASSESSMENT. Kontaminasi mikroba pada makanan menimbulkan masalah selama penyimpanan, pengangkutan, dan pemasaran. Dalam mengatasi masalah ini dilakukan pengawetan terhadap makanan, beberapa cara yang dapat dilakukan yaitu pengawetan secara konvensional dan iradiasi. Dalam penerapannya, teknik pengawetan makanan secara konvensional dan iradiasi memiliki kelemahan, sehingga perlu dilakukan studi komparasi menggunakan Life Cycle Assessment (LCA). Salah satu produk pangan yang dapat dilakukan studi LCA adalah tahu. Tujuan penelitian ini untuk menentukan dan membandingkan dampak lingkungan yang ditimbulkan dari penggunaan kunyit dengan iradiator sebagai pengawet tahu dengan pendekatan LCA. LCA dilakukan dengan menggunakan software OpenLCA dengan unit fungsional 41,8335 kg tahu. Data produksi tahu diperoleh dari produsen tahu yang berbasis di Kotagede Yogyakarta dan PAIR BATAN untuk data pengawetan tahu menggunakan iradiator. Sistem batas LCA mulai dari proses pembuatan tahu sampai menjadi produk jadi (cradle to gate). Dampak lingkungan yang disebabkan dari pengawetan tahu menggunakan kunyit maupun iradiator berupa acidification potential, climate change, eutrophication, freshwater aquatic ecotoxicity, human toxicity, marine aquatic ecotoxicity, photochemical oxidation, dan terrestial ecotoxicity. Kontribusi dampak terhadap lingkungan yang paling dominan terjadi pada pengawetan tahu menggunakan kunyit dan iradiator adalah climate change, dengan kontribusi sebesar 16,67136 dan 14,51325 kg CO2 eq.

Dumping of municipal solid waste into uncontrolled dumpsites is the most common method of waste disposal in most cities of India. These dumpsites are posing a serious challenge to environmental quality and sustainable development. Mumbai, which generates over 9000 t of municipal solid waste daily, also disposes of most of its waste in open dumps. It is important to analyse the impact of municipal solid waste disposal today and what would be the impact under integrated waste management schemes. In this study, life cycle assessment methodology was used to determine the impact of municipal solid waste management under different scenarios. Six different scenarios were developed as alternatives to the current practice of open dumping and partially bioreactor landfilling. The scenarios include landfill with biogas collection, incineration and different combinations of recycling, landfill, composting, anaerobic digestion and incineration. Global warming, acidification, eutrophication and human toxicity were assessed as environmental impact categories. The sensitivity analysis shows that if the recycling rate is increased from 10% to 90%, the environmental impacts as compared with present scenario would reduce from 998.43 kg CO2 eq t−1 of municipal solid waste, 0.124 kg SO2 eq t−1, 0.46 kg PO4−3 eq t−1, 0.44 kg 1,4-DB eq t−1 to 892.34 kg CO2 eq t−1, 0.121 kg SO2 eq t−1, 0.36 kg PO4−3 eq t−1, 0.40 kg 1,4-DB eq t−1, respectively. An integrated municipal solid waste management approach with a mix of recycling, composting, anaerobic digestion and landfill had the lowest overall environmental impact. The technologies, such as incineration, would reduce the global warming emission because of the highest avoided emissions, however, human toxicity would increase.

This study aimed to reduce the holistic environmental impacts of insulation materials proposed for the accommodation of a marine cargo ship, and suggest the optimal option for cleaner ship production, using life cycle assessment. With a commercial bulk carrier as a case ship, three major insulations were assessed, which were wool-based material (mineral wool or glass wool), expanded polystyrene, and polyurethane foam. The analysis was scoped based on ‘from cradle to grave’, while focusing on the following five representative environmental indicators: global warming potential100years, acidification potential, eutrophication potential, ozone depletion potential, and human toxicity potential. The assessment was performed in the platform of the GaBi software. The results showed that polyurethane foam would have the greatest impacts, especially in regard to global warming, eutrophication, and human toxicity. On the other hand, expanded polystyrene and wool-based material showed better environmental performance than polyurethane foam. For example, wool-based insulation was found, in terms of GWP and HTP, to produce 2.1 × 104 kg CO2-eq and 760.1 kg DCB-eq, respectively, and expanded polystyrene had similar results with respect to GWP, AP, and EP as 2.1 × 104 kg CO2-eq, 23.3 kg SO2-eq, and 2.7 kg Phosphate-eq, respectively. In fact, the research findings point out the shortcomings of current design practices in selecting insulation materials for marine vessels, while providing meaningful insights into the importance of the selection of appropriate insulation materials for marine vessels for cleaner shipping. Therefore, it is believed that this paper will make a sound contribution to enhancing future design practice and regulatory frameworks in response to environmental issues in the marine industry.

The Life Cycle Assessment (LCA) is one of the most important analytical tools available to provide the scientific basis of engineering solutions for sustainability. The focus of this study was a LCA (cradle to gate) of a product intended to be used in countertops. The functional unit chosen was 1 m2 of finished panel (countertop) and the boundary system involved the study of raw materials and product packaging and the panel’s production process. The chosen method for impact assessment was EPD (2018) available in SimaPro PhD software and Acidification, Eutrophication, Global Warming, Photochemical Oxidation, Abiotic Depletion (elements), Abiotic Depletion (fossil fuels), Water Scarcity and Ozone Layer Depletion were the impact categories considered. Results showed that the panel’s manufacturing is the process that presented the highest influence in all categories analyzed ranging from 88% on Abiotic Depletion to approximately 101% on Water Scarcity. Polyvinylchloride (PVC) is the greatest contributors to all impact categories except to Photochemical Oxidation that is the Polyester.

A cost combined life cycle environmental assessment was carried out to estimate the economic and environmental impact of wastewater treatment in the pulp production site of China. Results showed that the impact seen from abiotic depletion, acidification, eutrophication, global warming, fresh water aquatic ecotoxicity, and marine aquatic ecotoxicity categories represented an important contribution to the overall environmental impact, while the impact seen from human toxicity, terrestrial ecotoxicity, and photochemical oxidation categories played relatively small role. Specifically, the machine, electricity, coagulant production processes had the highest contribution to the overall environmental and economic impact. Improving electricity and chemicals applications efficiency are the efficient way to minimize overall environmental and economic impacts.
