Sustainability and application of life cycle assessment in welded structures

Abstract

As global environmental impacts have increased, modern societies have expressed a strong interest in implementing sustainable solutions to reduce emissions and use operational energy and natural resources. The construction industry is a leading promoter of significant environmental impacts because it consumes a significant amount of water, energy, and materials. Steel and welding are critical in all three major sectors of the industry: construction, infrastructure, and industry. This paper discusses the significance of meeting sustainable development goals in welded structures and identifies ways that this industry can help to reduce environmental impact and improve employment conditions while achieving economic growth, saving time, and maintaining structural quality. The paper discusses how to optimize various aspects ranging from raw material extraction to construction waste disposal using the life cycle assessment (LCA) methodology. It provides a starting point and demonstrates how these tools can contribute to more sustainable welded structures.
