Eco-effective sustainability assessment in buildings: Status and future directions for life cycle studies
AI summary Read the abstract
This review examines the status and future directions of sustainability assessment in buildings, covering life cycle assessment, circularity principles, and emerging concerns including indoor toxic emissions from endocrine-disrupting chemicals and microplastics, highlighting growing integration of absolute sustainability frameworks in the built environment.
Abstract Sustainability assessment is the process of estimating multidimensional impacts (environmental, social, economic) of a product, process, or activity. The concept is more evolved in the context of products and is emerging in the built environment domain. Sustainability assessment in buildings has aligned with the perspective of green buildings, encouraging sensitivity to the local environment and materials with lower energy and carbon footprint. There is an emerging focus on applying circularity principles, life cycle assessment, absolute sustainability, and estimating the long-term impacts of indoor toxic emissions in buildings mainly due to the COVID-19 pandemic, rising climate change concerns, and novel pollutants such as endocrine-disrupting chemicals and microplastics. This paper presents an overview of the existing literature on building life cycle sustainability assessment (LCSA) and scrutinizes the existing approaches from an eco-effectiveness perspective. A guiding framework is presented to integrate eco-effectiveness principles in the LCSA of buildings. The framework includes criteria for effectiveness in the context of the life cycle of buildings. This study attempts to integrate diverse perspectives, including limitations in this paper, to promote a holistic understanding of the impacts of a building over its life for improved sustainability. Such studies are crucial in the present context, where the role of the buildings is changing from reducing environmental impacts to ecosystem restoration.

Strategies for efficient management of microplastics to achieve life cycle assessment and circular economy
AI summary Read the abstract
This review examines strategies for managing microplastic waste through a circular economy and life cycle assessment (LCA) lens, arguing that current recycling practices and waste disposal methods are inadequate given the sheer volume of plastics entering ecosystems. The authors propose a conceptual framework integrating LCA principles into microplastic management to better quantify ecological risks and guide more sustainable plastic use policies.
Life cycle assessment in fashion industry: a systematic review
AI summary Read the abstract
This systematic review of life cycle assessments in the fashion industry (2010-2024) found persistent methodological inconsistencies that undermine the reliability of sustainability claims. The review identifies microplastic emissions from textiles as a growing but poorly incorporated impact category, highlighting a gap in understanding the full environmental footprint of clothing.
A critical review on plastic waste life cycle assessment and management: Challenges, research gaps, and future perspectives
AI summary Read the abstract
This review examines the full environmental impact of plastics from production through disposal, noting that life cycle assessments often produce unexpected results when comparing bio-based and petroleum-based plastics. A major gap exists because microplastic pollution is not yet factored into these environmental assessments, despite growing evidence of its ecological harm.
Microplastics as an Emerging Potential Threat: Toxicity, Life Cycle Assessment, and Management
AI summary Read the abstract
This review covers the full life cycle of microplastics, from how they enter the environment to their toxic effects on living organisms. Microplastics accumulate in aquatic and land ecosystems, where they can harm organisms by causing oxidative stress, disrupting hormones, and damaging organs. The authors emphasize that with global plastic production still rising, better waste management and recycling methods are urgently needed to reduce human and environmental exposure.
Transforming pollution into solutions: A bibliometric analysis and sustainable strategies for reducing indoor microplastics while converting to value-added products
AI summary Read the abstract
This review maps the research landscape of indoor microplastic pollution, which comes from everyday items like synthetic clothing, furniture, and packaging. People are constantly exposed to these tiny particles through indoor air and dust, with early evidence linking them to respiratory and digestive health issues. The study also highlights promising approaches for converting captured microplastic waste into useful products like biofuels and construction materials.
