{"title":"Reducing the environmental footprint of glass manufacturing","authors":"Scott Colangelo","doi":"10.1111/ijag.16674","DOIUrl":"10.1111/ijag.16674","url":null,"abstract":"<p>The glass industry is a significant source of greenhouse gas emissions due to its energy consumption profile and the use of fossil fuels in the manufacturing process. Most of the energy to produce glass is consumed in the process of treating raw materials to elevated temperatures, usually above 1500°C. Glass manufacturing also generates significant environmental impacts, such as greenhouse gas emissions, air pollution, water consumption, and waste generation. Therefore, improving the sustainability of glass manufacturing is a significant challenge for the industry and society. There are ways to reduce the energy consumption and emissions of glass melting, such as recycling glass, using oxy-fuel burners, improving furnace insulation and design, and adopting electric melting technologies. These methods can help save energy, lower costs, and enhance the sustainability and environmental footprint of the glass industry. However, the industry faces challenges and barriers, such as technical feasibility, economic viability, capital investment, and market acceptance. More research and development must be invested to improve the energy efficiency and environmental performance of glass melting. The objective of this paper is to provide an overview of the growth glass industry has made over the past 30 years and the remaining challenges for sustainable glass manufacturing with a focus on the fiberglass segment. Sharing of procedural methods, technical approaches, and results can help enable the global glass industry in our future sustainability challenges. The fiberglass segment included a broad technical view including glass chemistry development, product development, new industry codes and standards, melting development, computational fluid dynamic modeling, life cycle assessments, and sustainability goals linked to capital planning. The net result delivered a significant reduction in environmental emissions at the global enterprise scale. The implemented changes have taken decades, significant investments, and resources to plan and develop. Practices reviewed and implemented can help drive collaboration and commonality within the glass industry to achieve sustainability goals. Action is needed now if the glass industry is to meet global government demands of reducing carbon emissions by 55% by 2030 and zero carbon emissions by 2050 in alignment with the Paris Agreement on decarbonization.</p>","PeriodicalId":13850,"journal":{"name":"International Journal of Applied Glass Science","volume":"15 4","pages":"350-366"},"PeriodicalIF":2.1,"publicationDate":"2024-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ijag.16674","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141367219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effects of process parameters, diameter and position of the micro-holes, hole diameter, and pitch of the micro-hole array mold on the filling deformation of glass in contactless hot embossing were comprehensively investigated. It is found that placing the micro-hole farther away from the mold center renders decrease in both filling height and tip curvature but increase in the eccentricity of the embossed glass microlens. As a result, the formed glass microlens array shows a nonuniform distribution of filling height and tip curvature. Furthermore, reducing the pitch of micro-hole array mold can significantly improve the uniformity of formed microlens array.

Besides, the efficiency of combustion or energy utilization is directly affected by the extent of the melt-foaming. A fundamental understanding of key factors affecting melt foaming under the simulated oxy-fuel combustion environment will enable commercial E-glass fiber production to optimize both batch chemistry and operation conditions to achieve adequate furnace control. In this study, six types of E-glass batches with the same target glass composition were prepared by using four different CaO sources; calcined limes with different SO<sub>3</sub> contents, limestone, limestone with sodium sulfate, and a mixture of limestone and calcined lime. All batch samples were examined by HTMOS-EGA system (high temperature melting observation system with evolved gas analysis). HTMOS enables monitoring batch-to-melt conversation steps by using a high-resolution camera and EGA detects the evolved reaction gaseous, such as CO, CO<sub>2</sub>, and SO<sub>2</sub> via an Fourier transform infrared (FTIR) gas analyzer. Gases of water vapor, N<sub>2</sub>, and O<sub>2</sub> were introduced accordingly into the fused quartz crucible to simulate similar oxy-fuel atmosphere of the furnace operation. This study aimed to investigate the effects of different SO<sub>3</sub> contents in batches and different raw material chemistries on the foam formation in E-glass melts under the oxy-fuel atmosphere. Different raw materials were characterized by mineralogical analysis, chemical analysis, particle size distribution, chemical oxygen demanding (COD) level, and Brunauer–Emmett–Teller (BET) analysis. Although some of the batches contained the same SO<sub>3</sub> content, different foam formations resulted from the effect of the batch chemistry. Our detailed HTMOS-EGA investigations show that not only SO<sub>3</sub> content in the batch affects foam formation in E-glass melts, but also raw material chemistry and particle size have strong effects on the melt foaming in E-glass batch melting, especially for those of ingredients having hydroxide phases and/or finer particles with higher specific areas.</p>","PeriodicalId":13850,"journal":{"name":"International Journal of Applied Glass Science","volume":"15 3","pages":"276-291"},"PeriodicalIF":2.1,"publicationDate":"2024-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140573428","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
