Our mission is to offer a unique perspective on the mutually beneficial relationship between industries and the environment and, hence, promote practical and sustainable approaches to their coexistence. EIL maintains a global perspective, addressing the diverse needs and challenges faced by industries across developed and developing nations. The journal distinguishes itself by introducing fresh viewpoints into the scientific discourse, enriching our understanding of the intricate connection between industry and the environment.</p> <p style="font-weight: 400;"> </p> TULTECH en-US Environmental Industry Letters 2806-2965 Modeling the Circular Economy in Cellulose Synthesis from Recycled Materials: A Novel Construction Management Approach https://journals.tultech.eu/index.php/eil/article/view/152 <p>The adoption of circular economy principles is paramount to the sustainable transformation of cellulose production. The circular economy emphasizes the continuous use and recycling of materials, reducing waste and environmental impact. In cellulose production, incorporating recycled materials minimizes the demand for virgin resources, conserves energy, and mitigates environmental degradation. By embracing circularity, the cellulose industry contributes to resource efficiency, lowers its carbon footprint, and aligns with global sustainability goals, fostering a more resilient and eco-friendly production model. The present study developed a circular economy-based model as per recycled materials for the production of cellulose with the application of MATLAB 2019b software. In the created model, kinetic equations for cellulose synthesis are applied. As well, a sensitive analysis is done due to the behavior of the presented sustainable system during that time.</p> Reza Yeganeh Khaksar Copyright (c) 2024 Reza Yeganeh Khaksar https://creativecommons.org/licenses/by/4.0 2024-03-22 2024-03-22 2 1 30 43 10.15157/eil.2024.2.1.30-43 Green Chemistry in the Hydrolysis Process of Cellulose by Acids: Modelling, Optimization, and Life Cycle Assessment https://journals.tultech.eu/index.php/eil/article/view/150 <p>Cellulose is a critical material in a variety of engineering applications, holding significant importance in the evolving landscape of future lifestyles. The imperative for its production in the future is underscored by its versatile utility. However, conventional production processes involve the application of numerous chemicals. In this research, MATLAB-based simulation played a pivotal role in modeling the hydrolysis process during cellulose production. We further extended the simulation to optimize the production process. Notably, the application of life cycle assessment (LCA) brought an additional layer of sustainability to the study, resulting in the development of a more environmentally sound and sustainable acidification method for the hydrolysis process. This integrated approach holds promise for fostering a more sustainable and eco-friendly future in cellulose production.</p> Mohammad Eftekhari Hassan Monhemi Copyright (c) 2024 Authors https://creativecommons.org/licenses/by/4.0 2024-03-30 2024-03-30 2 1 1 15 10.15157/eil.2024.2.1.1-15 Green Branding of Czech-Poland Merchandise through Hydrogen Energy: A Study for Sustainable Production and Market Differentiation https://journals.tultech.eu/index.php/eil/article/view/151 <p>Through this research strategies for sustainable production and market differentiation are studied and explored. By tapping into the potential of hydrogen, businesses can minimize environmental impact and carve a distinct identity in the market, cultivating a reputation for sustainability. This research aims to uncover how embracing hydrogen as a clean energy source can benefit businesses and contribute to broader environmental responsibility goals. Exploring successful green branding examples and consumer responses, insights are provided to enable businesses to implement green branding initiatives effectively, driving both ecological and economic sustainability in the CzechPoland region. In the final stage of this research, three mathematical-conceptual models are developed for the implementation of green marketing in hydrogen energy production in both the Czech Republic and Poland regions, covering eco-friendly products and services, environmental responsibility, and corporate social responsibility (CSR).</p> Seyed Morteza Javadpour Copyright (c) 2024 Seyed Morteza https://creativecommons.org/licenses/by/4.0 2024-03-16 2024-03-16 2 1 16 29 10.15157/eil.2024.2.1.16-29
