MSW Incineration Bottom Ash-Based Alkali-Activated Binders as an Eco-Efficient Alternative for Urban Furniture and Paving: Closing the Loop Towards Sustainable Construction Solutions

Buildings, Journal Year: 2025, Volume and Issue: 15(9), P. 1571 - 1571

Published: May 7, 2025

Innovative approaches in the Portland cement industry, aligned with circular economy principles, offer a promising solution to reduce environmental impacts. These methods can initially target architectural elements lower structural demands, such as urban furniture and paving, before being applied areas higher usage. Alkali-activated binders (AABs) made from secondary resources present sustainable alternative (PC), promoting resource recovery, conservation, low-carbon economy. Incinerator bottom ash (IBA), traditionally landfilled, has shown potential precursor for AABs due its aluminosilicate content. Repurposing IBA paving transforms it into valuable resource. Accordingly, this is first study utilize sole or applications. Research, including state-of-the-art studies proof of concept developed work, demonstrates that IBA-based produce cast concrete suitable non-structural elements, meeting technical, environmental, ecotoxicological standards. Using AAB formulations not only reduces reliance on primary raw materials but also contributes significant energy savings binder production lowers greenhouse gas (GHG) emissions, resulting reduced carbon footprint. Furthermore, producing local residual resources, IBA, facilitates reintegration municipal waste cycle at point origin, fostering approach development supporting

Published: March 9, 2024

The construction sector, a significant consumer of energy, possesses the potential to realize substantial environmental and economic advantages through adoption innovative technologies design approaches. Notably, Passive House standard, exemplified by energy-efficient single-family homes, emerges as prominent solution. This study analyzes five external wall systems across multiple stages: (i) literature review examination techniques within passive utilizing Database; (ii) material technological assessment three wood-based two masonry constructions; (iii) an in-depth thermal performance analysis selected partitions; (iv) Life Cycle Assessment (LCA) systems. Our findings indicate that among homes built 50.94% utilized timber constructions, while 34.21% employed masonry. Thermal revealed wall, EW-M-01, exhibited superior efficiency with heat transfer coefficient (U-value) 0.0889 W/m2K. Meanwhile, wooden EW-T-01, led its category U-value 0.1000 LCA highlighted EW-T-02 presented lowest integrated non-renewable energy demand (PENTR) at 425.70 MJ/kg most favorable Global Warming Potential (GWP), reduction 55.51 kg CO2e.
