Perspective: Comparison of end-of-life scenarios of municipal solid waste from viewpoint of life cycle assessment

Frontiers in Built Environment, Journal Year: 2022, Volume and Issue: 8

Published: Sept. 14, 2022

Municipal solid waste management systems use several techniques for municipal at the end-of-life stage. However, to take major differences identify good practices and optimal actions, more complex comparisons need be discussed. This perspective article discusses advances future directions of given specific research area from viewpoint author with review professional literature presentation other authors’ work. work assesses compares environmental impacts two scenarios (landfilling conventional incineration) in European Union including practical life cycle assessment. To find answers, eight main impact categories, emissions, primary energies were analyzed using GaBi 8.0 software. Based on results, it can concluded that case incineration, emissions electricity power credit are higher. These results used compare treatment processes lower impacts, perform further these processes.

A Methodological Framework to Foster Social Value Creation in Architectural Practice

Sustainability, Journal Year: 2023, Volume and Issue: 15(3), P. 1849 - 1849

Published: Jan. 18, 2023

The building industry is essential for a national transition towards circular economy (CE) in Denmark. Danish state subsidises the affordable housing sector, which largest single sector within industry, making an driver transition. social components of sustainability are considered crucial to ensuring quality environmental and economic CE. However, value creation (SVC) has been neglected processes, public investments being used without policymakers thoroughly assessing CE’s socioeconomic efficiency effectiveness. therefore needs integrated methodologies support comprehensive decision on CE during construction renovation. SVC apparent field architectural firms. Two surveys were conducted among business managers firms identify challenges potentials regarding architects’ practices. results described analysed this study. Several impact categories, indicators tools identified, discussed summarised methodological framework that can architects about constructing renovating housing. Further refinement dynamic iterative decision-making anticipated as future work.

Including Nature-Based Success Measurement Criteria in the Life Cycle Assessment

IntechOpen eBooks, Journal Year: 2023, Volume and Issue: unknown

Published: March 6, 2023

Conventional life cycle assessment (LCA) is a technique to assess environmental impacts associated with all the stages of product’s or process. Such along product process are assessed via criteria establish success when accounting for resource intake, waste, and emissions fluxes. In most cases, range may vary, defined by designer’s aims, failing evaluate parts said completely. This before follow “reducing unsustainability” paradigm (RUP), changes needed toward an based on “achieving sustainability” (ASP). Thus, this chapter embarks search approaches, assuming biomimicry principles can improve current LCIA tools. Comprehending LCA done literature review. Results showed that tools continue be developed under RUP, where three approaches present great potential ASP. A discussion over difference in assessing two case studies built environment, net-zero-energy buildings, sustainable construction projects both paradigms presented.

Promoting Circular Economy of the Building Industry by the Use of Straw Bales: A Review

Buildings, Journal Year: 2024, Volume and Issue: 14(5), P. 1337 - 1337

Published: May 8, 2024

Over the past decade, concept of a circular economy has increasingly gained attention as framework for guiding businesses and policymakers. Given its significant environmental impact, building industry plays pivotal role in transition toward economy. To address this, our review proposes bio-based material, specifically straw bale, which elaborates on circularity buildings based 3R principles economy: reduce, reuse, recycle. In terms “reduce” principle, straw-bale can reduce construction waste, energy requirements, carbon emissions. Regarding “reuse” utilize agricultural waste resources are easily disassembled due to their prefabrication. As “recycle” undergo physical, biological, biochemical conversion processes (thermochemical conversion), yielding both wooden composite boards potential biogas biomass fuels electricity heating. This study evaluates contribution packaging use raw using determine future research opportunities achieve The results this offer solutions interdisciplinary insights researchers practitioners interested environment.

Sustainability considerations of nuclear power in space transportation and infrastructures

Research Square (Research Square), Journal Year: 2024, Volume and Issue: unknown

Published: Aug. 27, 2024

Nuclear thermal propulsion (NTP) and nuclear electric (NEP) systems are considered to be potential enablers for exploring Mars beyond. The fission surface power can provide continuous heat electricity, which complements solar on the Moon Mars. attracting spacefaring nations stakeholders again after Space Race era due their advantages envisioned applications. This paper examines space from a few sustainability perspectives. First, logistics transportation perspective, we identify operational regimes where could complement or outperform chemical rocket propulsion. Second, self-engineering technologies that may enhance reliability of in orbit surface. Lastly, discuss extraterrestrial infrastructures, inspired by design approaches adopted architecture, engineering, construction (AEC) industry, contribute cislunar circular economy.
