“…The "life cycle assessment" cluster presents the central concept in assessing the environmental impact from plastic production to disposal stages. The connection between these two clusters is clearly seen in the term "plastic waste", which is linked to the concept of "life cycle assessment", implying the importance of the LCA approach in measuring the environmental impact of plastic waste management (Anshassi & Townsend, 2021). This analysis strengthens that the scientific literature is focused on integrating LCA concepts in efforts to manage plastic waste, encompassing reduction, recycling (Santos et al, 2022), and better environmental impact management (Alhazmi et al, 2021).…”

Timbulan dan pembuangan sampah plastik menjadi masalah global yang semakin rumit dan perlu diatasi. Studi ini bertujuan untuk melakukan analisis bibliometrik dari penilaian siklus hidup (LCA) tentang sampah plastik. Data dari tahun 2013 hingga 2022 dikumpulkan dari Scopus dan Web of Science. Data yang telah dikumpulkan kemudian digabungkan dan dihapus duplikasinya menggunakan R v.4.2.3 dan R studio v.3.8.6. Setelah itu, data dianalisis dan divisualisasikan dengan bantuan Biblioshiny. Data yang dianalisis meliputi publikasi tahunan artikel ilmiah, kontribusi berdasarkan negara, kata kunci yang relevan berdasarkan peta pohon, pola pertumbuhan penelitian, pengelompokan topik, posisi penelitian berdasarkan peta tematik, dan peta struktur konseptual dalam cakupan kata kunci terkait. Tren publikasi tahunan menunjukkan pertumbuhan substansial dari 30 artikel pada tahun 2013 menjadi 631 artikel pada tahun 2022, yang menandakan kesadaran dan perhatian terhadap permasalahan sampah plastik. Tiongkok, Amerika Serikat, dan Italia memimpin publikasi tahunan sekaligus sebagai negara-negara yang paling banyak dikutip artikel-artikelnya, mengingat status mereka sebagai produsen plastik terbesar di dunia. Kata kunci yang paling relevan dari peta pohon juga ditampilkan adanya integrasi yang kuat antara upaya daur ulang plastik dan LCA dalam pengelolaan dampak lingkungan dengan kata kunci yang menonjol antara lain daur ulang, LCA, pengelolaan sampah, sampah plastik, dampak lingkungan, dan ekonomi sirkular. Studi ini pada akhirnya memberikan wawasan mendalam mengenai posisi penelitian dan arah masa depan terkait studi LCA tentang sampah plastik, yang semakin meningkat karena pentingnya pengelolaan sampah plastik berkelanjutan. Kajian ilmiah dalam bidang ini diharapkan terus berkembang untuk mendukung kesadaran dan komitmen seluruh pemangku kepentingan dalam mengatasi permasalahan sampah plastik di seluruh dunia. Abstract The generation and disposal of plastic waste become an increasingly complicated global concern that needs to be overcome. This study aims to conduct a bibliometric analysis of life cycle assessment (LCA) studies on plastic waste. Data from 2013 to 2022 were collected from Scopus and Web of Science. Collected data were merged and deduplicated using R v.4.2.3 and R studio v.3.8.6. Afterward, data were analyzed and visualized by Biblioshiny. The analyzed data encompass scientific production output, contributions by country, relevant keywords by tree map, research growth pattern, topic clustering, research position by thematic map, and conceptual structure map within this scope. The annual publications trend denotes a substantial growth from 30 articles in 2013 to 631 articles in 2022, signifying awareness and attention towards plastic waste issues. China, the United States, and Italy have led annual publications as well as the most cited countries, given their status as the world’s largest plastic producers. The most relevant keywords from the tree map also show a strong integration between plastic recycling efforts and LCA in managing the environmental impact with prominent keywords including recycling, LCA, waste management, plastic waste, environmental impact, and circular economy. This study finally provides profound insights into research positions and future direction related to LCA studies on plastic waste, which are escalating at the forefront because of the importance of sustainable plastic waste management. Scientific studies in this domain are expected to continuously grow to support the awareness and commitment of all stakeholders in addressing plastic waste issues worldwide.

“…One approach to quantify the negative impacts of plastic waste is to perform a life cycle assessment (LCA) (Alhazmi et al, 2021;Anshassi & Townsend, 2021;Neo et al, 2021;Santos et al, 2022). This analysis considers the environmental impacts of the production, usage, and waste-processing phases of plastics.…”

“…Some of the studies have selected the waste management strategies based on the use of life cycle assessment (LCA). It is commonly used as a systematic tool for i) comparing different treatment strategies (Anshassi and Townsend, 2021), ii) analyzing the environmental impacts of specific treatment technologies (Erses Yay, 2015), iii) providing modifications of existing process to minimize environmental impacts (Koroneos and Nanaki, 2012). Wang et al (2022) used the LCA and material flow analysis to investigate the environmental impacts of changing MSW management from a landfill and energy from waste mode to a multi-technology mode.…”

A significant amount of municipal solid waste (MSW) generation and ineffective management can cause adverse impacts on the environment (air and water pollution) and human health. Therefore, a sustainable approach for handling MSW is required. This study aims to develop a tool to select the most promising MSW management system using the superstructure optimization technique to ensure that the selected system can achieve minimization of the total annual cost and environmental impacts. This can lead to a multi-objective superstructure optimization problem solved by using the augmented ϵ-constraint method. The developed model is based on the concept of material balance and all potential technologies include anaerobic digestion, pyrolysis, gasification, incineration, sanitary landfill, material recovery facility and composting. The proposed methodology is applied to synthesize the MSW management system in Warin Chamrap district to determine its applicability. In this research, the composition of MSW include organics, paper, plastic, glass, and others. The results show that the Pareto-optimal solutions optimizing both total annual cost and environmental impacts can be developed. The MSW management system with the lower total annual cost tends to have the higher environmental impacts and the trade offs between each objective can be identified so the decision makers are able to consider before making their decision. Further investigation on sensitivity analysis reveals that the selling prices of products, annual capital cost and operating cost factors have different degree of impacts on the waste management strategies and total annual cost.

Life Cycle Assessment and Life Cycle Cost of an Innovative Carbon Paper Sensor for 17α-Ethinylestradiol and Comparison with the Classical Chromatographic Method

et al. 2022

Nowadays there is a growing concern with the environment and sustainability, which means that better methods, including pollutants analysis, with less consumption of materials, organic solvents, and energy, need to be developed. Considering the almost inexistent information about the topic, the main goal of this work was to compare the environmental impacts of two analytical methods, a traditional one based on liquid chromatography with fluorescence detection and a newly developed carbon paper sensor. The selected analyte was 17α-ethinylestradiol, which is a contaminant of emergent concern in aquatic ecosystems due to its endocrine disruptor behavior. The life cycle assessment data showed that the sensor detection presents an almost negligible environmental impact when compared with the extraction step (the same for both methods) and the liquid chromatographic determination (roughly 80 times higher than with the sensor). The sensor values for all categories of damage are below 3% of the total method impacts, i.e., 1.6, 1.9, 2.4, and 2.9% for resources, climate change, human health, and ecosystem quality. The extraction represents 98.1% of the sensor environmental impacts (and 99.6% of its life cycle costing) and 38.8% of the chromatographic method. This study evidences the need of developing and applying greener analytical (detection and extraction) strategies.
