Life Cycle Sustainability Assessment of Bio-Based and Recycled Materials in Eco-Construction Projects

Abstract

The construction sector is responsible for damaging the environment, using lots of energy and emitting copious greenhouse gases. As ecological issues grow, projects that use bio-based and recycled materials in buildings are becoming more popular. It gives us better ways to build by lowering the environmental impact and supporting reuse of resources. Using a Life Cycle Sustainability Assessment, this study assesses how these materials perform with regard to environmental, economic and social factors. The industry and process input-output models are included in the framework’s LCSA method, which adds Life Cycle Assessment Life Cycle Costing, and Social Life Cycle Assessment . Existing case studies, EPDs and reports from companies were all sources of data used in this study. The process of economic and social assessment drew from stakeholder surveys along with market data and social hotspot databases. The research demonstrates that using bio-based and recycled materials results in less carbon emissions, less energy being used and less loss of important resources than traditional ones. Bio-based materials tend to be more expensive at first, but they give positive economic and health results over the long run. These materials encourage new job opportunities and are good for the community. The results support the idea that LCSA is essential for making environmentally friendly choices in construction and encourage using circular economy ideas in the building process.
