“…In this context, the goal of this study is to assess the carbon footprint of a novel biocomposite, MycoBamboo, as a novel insulation material for renovating building facades, and to analyze each process involved in its production. Despite their already established architectural potentials [27][28][29][30], the currently available literature and knowledge about the process efficiency and relative environmental impacts of these bio-based composites are very fragmented [31][32][33][34]. Indeed, the mycelium-based composites are new promising solutions for construction, and a deep understanding of their ability to mitigate the climate change over their life cycle is needed.…”

This research explores the carbon removal of a novel bio-insulation composite, here called MycoBamboo, based on the combination of bamboo particles and mycelium as binder. First, an attributional life cycle assessment (LCA) was performed to define the carbon footprint of a European bamboo plantation and a bio-insulation composite, as well as its ability to remove CO2 along its lifecycle at a laboratory scale. Secondly, the Global Worming Potential (GWP) was estimated through a dynamic LCA with selected end-of-life and technical replacement scenarios. Finally, a building wall application was analyzed to measure the carbon saving potential of the MycoBamboo when compared with alternative insulation materials applied as an exterior thermal insulation composite system. The results demonstrate that despite the negative GWP values of the biogenic CO2, the final Net-GWP was positive. The technical replacement scenarios had an influence on the final Net-GWP values, and a longer storage period is preferred to more frequent insulation substitution. The type of energy source and the deactivation phase play important roles in the mitigation of climate change. Therefore, to make the MycoBamboo competitive as an insulation system at the industrial scale, it is fundamental to identify alternative low-energy deactivation modes and shift all energy-intensity activities during the production phase to renewable energy.

“…Akhimien et al [30], for instance, provided a review for circular economy interventions in buildings under seven main circular economy principles or strategies and highlighted the possible gaps in research on this topic. Similarly, Cimen [33] and Eberhardt et al [5] presented a review of the literature on the circular economy in the construction and built environment sector, highlighting key findings and gaps in the reviewed studies. Munaro et al [3] provided a state-of-the-art review on CE research and focused on analyzing what has already been done in terms of circular practices in the construction value chain.…”

“…Moreover, despite the efforts being made, the wide-scale adoption and implementation of CE in building design and construction strategies still lack a common direction, often implemented through small-scale and fragmented approaches [3,5,33]. Buildings are complex and dynamic, involving many different systems and components, each with its own life cycle, functions, and characteristics.…”

“…The literature also indicates that CE initiatives are directed toward different focus areas and use different tools [38]. Thus, it is argued that these fragmented initiatives prevent the universal adoption of CE in the building industry [33,35]. Studies indicate that there is also a lack of knowledge on the definition of CE, its fundamental principles, and its implementation in an innovative manner in the building sector's business model [27,36], while Kirchherr and Van Santen [39] indicate that most CE studies focus on developed countries, making many of the CE studies irrelevant to construction in less-developed countries.…”

Circularity in the New Gravity—Re-Thinking Vernacular Architecture and Circularity

The mounting climate change crisis and the rapid urbanization of cities have pressured many practitioners, policymakers, and even private investors to develop new policies, processes, and methods for achieving more sustainable construction methods. Buildings are considered to be among the main contributors to harmful environmental impacts, resource consumption, and waste generation. The concept of a circular economy (CE), also referred to as “circularity”, has gained a great deal of popularity in recent years. CE, in the context of the building industry, is based on the concept of sustainable construction, which calls for reducing negative environmental impacts while providing a healthier indoor environment and closing material loops. Both vernacular architecture design strategies and circular economy principles share many of the same core concepts. This paper aims at investigating circular economy principles in relation to vernacular architecture principles in the built environment. The study demonstrates how circular principles can be achieved through the use of vernacular construction techniques and using local building materials. This paper will focus on Egypt as one of the oldest civilizations in the world, with a wide vernacular heritage, exploring how circularity is rooted in old vernacular settlements and how it can inspire contemporary circular practices.

“…Three stages such as site preparation stage, construction stage and post construction stage create waste and pollution to the environment. Construction works such as land excavation, roadworks, building works, demolition and renovation [3]. Construction works destroy the natural environment which provides shelter for flora and fauna.…”

The ASEAN population will increase to 724.8 million by the year 2030 and the urbanization rate increases with years. This leads to the development of the construction industry to fulfil the fundamental social and physical requirements. Construction activities create an adverse negative impact on the environment, such as pollution and damage to the environment. This article will study more about the construction and demolition waste (C&D waste) and it can be founded in various construction stages. Therefore, the government and authorities introduce environmental management practices to mitigate the negative impact on construction on the environment and minimize the pollution at the source. What, why and where are terms required to consider before the implementation of environmental management practice. The government policies of Malaysia, Singapore and Thailand are summarized. Approximately 10% of total synthetic carbon dioxide (CO2) sourced from concrete production. The content more emphasizes the green materials generated from agricultural waste to replace the silica in concrete. The bamboo is used as interior decoration and material for building construction. Green materials technology is solar panel, solar thermal collector, geothermal technology, hydropower technology and cooling roof system.
