Supporting circularity in construction with performance-based deconstruction

Growing needs for sustainable consumption and production of resources call for controlling substantial amounts of waste in the construction sector. Planned dismantling of structures (i.e., deconstruction) maximizes the utilization of resources and enables Circularity in Construction (CiC). Since there is a lack of comprehensive guidance for deconstruction, this paper aims to develop a conceptual model that extracts resources from the built environment through targeted deconstruction and helps to reuse them in new construction. Qualitative and quantitative analyses were performed to identify the stakeholders' needs and requirements; factors that strongly affect deconstruction processes; technologies to be adopted; and the guidelines to follow. The quantitative study included Political, Economic, Social, Technological, Legal, and Environmental analysis, Co-occurrence Network analysis, and interaction analysis. The results unveiled 37 unified barriers to CiC across six categories; 42 deconstruction-related factors among four categories: Feasibility, processes, profitability, and environmental impact; and 32 unique synergies between deconstruction-related factors and Construction 4.0 technologies. The proposed model formalizes the link between existing facilities' resources and new construction projects for efficient decision-making in the planning and execution of deconstruction. The novelty of this model lies in considering people, processes, technology, and guidelines at every step to ensure the desired change.

Topology of Ethos: Anthropology Study of the Phenomenon of Home

Introduction. The purpose of the article is to consider the phenomenon of the Home in the philosophical and anthropological aspect, to show the prospects of studying the topology of human existence in the form of the immediate environment and everyday practices, set through ethos as an immanent norm of human existence. To do this, an attempt is made to define the boundaries of the Home as a space of human self-sufficiency, and ethos as a condition for the possibility of understanding communication and connection between the individual and their external environment, which allows us to return to the conceptual consideration of the ultimate foundations of human existence.Methodology and sources. An attempt is made on the basis of a critical analysis of nonclassical and post-classical philosophy (phenomenology, existentialism, structuralism) to consider the process of deconstruction of the foundations of human existence. Based on such concepts as the “Lebenswelt” by E. Husserl, “Dasein” by M. Heidegger, studies of the space of human existence by M. Merleau-Ponty and U. Eko, and definitions of the ethos by P. Bourdieu, the main boundaries of the phenomenon of the Home are determined, which is introduced into the discourse of philosophical anthropology.Results and discussion. The phenomenon of the Home, considered in the anthropological aspect, allows us to interpret the goal of the civilization development process as the “domestication” of being, the construction of an “inhabited world”, in which an individual gets the opportunity to realize their existence in an event with “his others”. The life world is formed as a constant movement of the inhabitants of the home, their active, understanding communication within the boundaries of a common space and a common way of life, its forms and rules, that is, a common ethos.Conclusion. As a condition of the human way of being and its ultimate basis, can be considered Home as a community of I and “its others”, having its own topology, the relationship between which is set by a unique ethos.

Colourization of Photographs as Remix

This paper seeks to explore the concept of colourization of black and white photographs as a form of reflexive remix. Colourized photographs call into question notions of the authentic and the “spectacular aura,” nostalgia, pastiche, and tradition. Such colourization is subject to controversy: some argue it honours the original photograph through its efforts to be historically accurate, while others argue it degrades the original. However, colourized photographs present a new expression worthy of consideration because they can capture experiences and emotions differently. In particular, the process of deconstruction and reconstruction through technologies such as artificial intelligence can create something unique that is perhaps missing from the original. As a remix, the colourization of black and white photographs makes the viewer question what they feel, how they perceive, and how they view history.

Family photos and architectural representation: Using photo-collage sketchbook to understand behaviour patterns in family apartment buildings

This article presents a three-step process of collecting, deconstructing and reconstructing family photos in ethnographic research investigating the sociocultural aspects of behaviour patterns in family apartment buildings. The first author conducted the study for her Ph.D. thesis in architectural design, supervised by the second and third authors. As an architect, the first author created a photo collage sketchbook, combining various representational techniques of her profession with family photographs. While observing the family apartment building and trying to understand the “gecekondu” where the participants lived before the family apartment building, the researcher realised that the interviews were insufficient, and this problem forced the use of a photo collage sketchbook. To synthesise ethnographic knowledge, research started with obtaining family photos. After extracting and grouping, the deconstruction process began. Deconstructed layers are then reconstructed by using various architectural representation techniques and text. This photo collage sketchbook has helped us understand various aspects of the family apartment buildings related to architecture and culture. While doing this, the sketchbook prepared with visual contents combined with short notes represents the data collecting, organising, analysing, interpretation, knowledge-making, and presentation stages. In working with a photo collage sketchbook, obtaining family photographs and overlapping the photographs and interviews’ narratives appear challenging. Therefore, collective interviews have been a critical move to compare and verify the memories recalled by the participants. While interviewing, it is vital to show the photos to every participant from a particular age group because they contribute differently to the photo components because of the place experience. So, this study is not about a set of instructions or tools but experiences about the process or approach to constructing ethnographic knowledge.

Performance and mechanism of efficient activation of peroxymonosulfate by Co-Mn-ZIF derived layered double hydroxide for the degradation of enrofloxacin

Due to the uncontrolled synthesis of layered double hydroxides (LDHs), a simple and efficient strategy was needed to construct high-performance LDHs. Herein, Co-Mn-ZIF was used as the sacrificial template to form cobalt-manganese-nickel LDH (M−Co−Mn−Ni LDH) through the process of deconstruction and reconstruction. Due to the sufficient in-situ etching of the Co-Mn-ZIF template, M−Co−Mn−Ni LDH exhibited a larger specific surface area (482.4 m2/g) and pore volume (3.3 × 10−2 cm3/g) as well as easier diffusion and interaction with reaction sites of organic molecules. The prepared M−Co−Mn−Ni LDH showed high catalytic performance for the degradation of enrofloxacin (ENR) by activating peroxymonosulfate (PMS), with the removal rate of 88.5 % within 30 min. The quenching reaction and electron paramagnetic resonance (EPR) analysis results indicated that SO4•− and 1O2 were main active substances in the oxidation process of ENR. In addition, the Co-Mn-Ni LDH/PMS system was stable and almost unaffected by pH values, organic and inorganic substances, and it could achieve high removal efficiency in various pollutant samples. This work provided a convenient and efficient approach for the construction of high-performance MOFs derived LDHs catalysts.

Research on building deconstruction based on BIM technology

This paper delves into the revolutionary role of Building Information Modelling (BIM) technology in building deconstruction and its profound implications for sustainable development. Conventional demolition methods often neglect considerations of material reuse and environmental ramifications. BIM emerges as a versatile solution, offering sophisticated analytical tools that amplify efficiency, safety, and material traceability throughout the deconstruction process. In this paper, the lifecycle applications of BIM are further explored. Traversing from the planning stage to material handling and recycling, the important contribution of BIM to the circular economy is highlighted. Despite being in the nascent stages of adoption for building demolition, this paper posits that comprehensive integration of BIM holds the promise to fundamentally transform the construction sector, ensuring its alignment with sustainability objectives. Case studies and real-world applications are meticulously analysed to furnish empirical evidence corroborating these assertions, shedding light on the practical and environmental advantages of leveraging BIM in deconstruction.

Autoxidation Catalysis for Carbon-Carbon Bond Cleavage in Lignin.

Selective lignin depolymerization is a key step in lignin valorization to value-added products, and there are multiple catalytic methods to cleave labile aryl-ether bonds in lignin. However, the overall aromatic monomer yield is inherently limited by refractory carbon-carbon linkages, which are abundant in lignin and remain intact during most selective lignin deconstruction processes. In this work, we demonstrate that a Co/Mn/Br-based catalytic autoxidation method promotes carbon-carbon bond cleavage in acetylated lignin oligomers produced from reductive catalytic fractionation. The oxidation products include acetyl vanillic acid and acetyl vanillin, which are ideal substrates for bioconversion. Using an engineered strain of Pseudomonas putida, we demonstrate the conversion of these aromatic monomers to cis,cis-muconic acid. Overall, this study demonstrates that autoxidation enables higher yields of bioavailable aromatic monomers, exceeding the limits set by ether-bond cleavage alone.

Application of Aromatic Ring Quaternary Ammonium and Phosphonium Salts–Carboxylic Acids-Based Deep Eutectic Solvent for Enhanced Sugarcane Bagasse Pretreatment, Enzymatic Hydrolysis, and Cellulosic Ethanol Production

Deep eutectic solvents (DESs) with a hydrophobic aromatic ring structure offer a promising pretreatment method for the selective delignification of lignocellulosic biomass, thereby enhancing enzymatic hydrolysis. Further investigation is needed to determine whether the increased presence of aromatic rings in hydrogen bond receptors leads to a more pronounced enhancement of lignin removal. In this study, six DES systems were prepared using lactic acid (LA)/acetic acid (AA)/levulinic acid (LEA) as hydrogen bond donors (HBD), along with two independent hydrogen bond acceptors (HBA) (benzyl triethyl ammonium chloride (TEBAC)/benzyl triphenyl phosphonium chloride (BPP)) to evaluate their ability to break down sugarcane bagasse (SCB). The pretreatment of the SCB (raw material) was carried out with the above DESs at 120 °C for 90 min with a solid–liquid ratio of 1:15. The results indicated that an increase in the number of aromatic rings may result in steric hindrance during DES pretreatment, potentially diminishing the efficacy of delignification. Notably, the use of the TEBAC:LA-based DES under mild operating conditions proved highly efficient in lignin removal, achieving 85.33 ± 0.52% for lignin removal and 98.67 ± 2.84% for cellulose recovery, respectively. The maximum digestibilities of glucan (56.85 ± 0.73%) and xylan (66.41 ± 3.06%) were attained after TEBAC:LA pretreatment. Furthermore, the maximum ethanol concentration and productivity attained from TEBAC:LA-based DES-pretreated SCB were 24.50 g/L and 0.68 g/(L·h), respectively. Finally, the comprehensive structural analyses of SCB, employing X-rays, FT-IR, and SEM techniques, provided valuable insights into the deconstruction process facilitated by different combinations of HBDs and HBAs within the DES pretreatment.

Synthesis of dienes from pyrrolidines using skeletal modification

Saturated N-heterocyclic pyrrolidines are common in natural products, medicinal compounds and agrochemicals. However, reconstruction of their skeletal structures creating new chemical space is a challenging task, and limited methods exist for this purpose. In this study, we report a skeletal modification strategy for conversion of polar cyclic pyrrolidines into nonpolar linear dienes through a N-atom removal and deconstruction process. This involves N-sulfonylazidonation followed by rearrangement of the resulting sulfamoyl azide intermediates. This can be an energetically unfavorable process, which involves the formation of active C–C π bonds, the consumption of inert C–N and C–C σ bonds and the destruction of stable five-membered rings, but we have used it here to produce versatile conjugated and nonconjugated dienes with links of varying lengths. We also studied the application of this method in late-stage skeletal modification of bioactive compounds, formal traceless C(sp2)–H functionalization and formal N-atom deletion.

Utilising 3D fashion design software to enable remanufacturing in sportswear

ABSTRACT The boundaries between physical and digital practice within fashion are becoming increasingly blurred, with recent technological advancements seeing brands launching virtual collections and retailing fashion products for the Metaverse. This foray into a digital space has acted as a catalyst for the use of digital software in practical design and make applications and provided opportunities for innovation when challenging ecological parameters. Utilising an action research approach, this paper proposes three cycles of iterative problem solving, creating an interplay between physical and virtual garment experimentation. A process of product deconstruction, digitisation and remanufacture has provided insights into the possibilities of new practices enabling garment remanufacture methods for circularity. Findings have indicated that the use of 3D fashion design software can aid in the diversion of whole garments from the landfill and help enable commercial viability in methods of remanufacture within the sportswear market sector.

Embedding Sustainability Justice in Greek Secondary Curricula through the DeCoRe Plus Methodology

This paper describes the processes of embedding Sustainability Justice in secondary education curricula for economic courses in Greece applying the DeCoRe plus methodology and participatory action research. These processes resulted in a reconstructed curriculum that was implemented by nine teachers teaching courses in economics. Sustainability justice emphasizes the ethics and praxis of education for sustainability and requires an understanding of the curriculum as a process and praxis and teaching as an ethical and political praxis. The implementation of the diagnostic evaluation of DeCoRe plus showed that economics teachers in Greece select more behavioral than constructive-emancipatory teaching approaches. On the other hand, the implementation of the reconstructed curriculum units in their courses using the DeCoRe plus methodology revealed a shift from instructive to constructivist and emancipatory teaching and learning approaches. Teachers by the great majority declared the political and ethical perspective of teaching and seeing curriculum as a living text that can always be under the process of deconstruction, construction, and reconstruction.

TERRITORIAL POLICY OF THE EU STATES: TARGETS, TOOLS, ACHIEVEMENTS

The article presents the process of formation and development of the territorial policy of the European Union and its Member States. The author defines the goals and logic of territorial and political transformation of national territorial and political systems in the context of glocalisation – macro-regional integration of national entities in Europe, where regions are proclaimed the main beneficiary of reforms, and place is proclaimed the topos, the basis of the political process. Place-based politics, development of self-government systems, decentralisation reforms, promotion of local and regional autonomy and systemic asymmetry, where status is determined by the scope of functional responsibilities, are considered as processes of de(re)construction of a new model of polycentric governance and political interaction in the context of formation of an effective supranational political space of the EU. The author examines the peculiarities of the transformation of systemic relations in the EU member states, including the relations between metropolises and non-European remote territories (on the example of France and the Netherlands), and the relations between the supranational centre of the EU and these remote territories of the EU states, which have the specifics of asymmetric involvement in the territorial and political processes of the EU. The author notes that the development of the EU political space is ahead of the process of transformation of the territorial morphology, which is manifested in the expansion of political participation rights at the supranational level and the preservation of restrictions at the national level. The paper notes that the EU’s spatial development strategy is formed on the basis of an institutional compromise between different levels of political decision-making in a multi-level and polycentric system of territorial and political relations and is provided by a set of instruments. This complex is formed by: the policy of vertical and horizontal cooperation; multilevel and polycentric governance; practices of regional and autonomy; asymmetry of statuses and functional roles; 4D decentralisation instruments; standardisation and measurement (indexation) of standards; instruments of consociative democracy, which provide for “inclusion policy”, “effective citizenship”, “mobile political participation” in the context of deepening integration, increasing mobility, and changing the functional significance of the institution of citizenship.

Zapping Zone and Level Five. Between the visitor’s experience of the video installation and the filmmaker’s reflection of the essay film

The displacement from the essay film to the video installation has in Chris Marker one of its first and most relevant figures. The comparative study of Zapping Zone. Proposal for an imaginary television (1990) and Level Five (1997) allows for the analysis of the construction and complexification, and the deconstruction and saturation processes that take place between the most complex expression of the Markerian essay film and its transformation into the video installation. Zapping Zone responds to the embodiment of both the magmatic stage of the postmodern audiovisual era and the starting point of the filmmaker's work (documentaries, essay films, video installations, etc.), which would be the opposite of the writer’s blank page: a saturated world of images that needs to be selected, analysed and worked on in order to build meaning. Level Five offers the filmmaker’s reflection on that same reality, applied to the Battle of Okinawa, through a complex audiovisual thinking process that hybridises different types of images—documentary and fictional; analogue and electronic—devices—epistolary video diary, video game and cyberspace—and their authorial subjectivities—Laura, Laura’s lover and Chris—in order to reflect on the relationship between these audiovisual forms and spaces and the thematic axis memory-pain-oblivion.

ANALYSIS OF ACID MIXTURE COMPARISON ON THE PROCESS OF DESTRUCTION OF LEAD METAL (Pb) ON SAMPLE OF CARPET SHELL’S MEAT (Ruditapes variegatus)

ABSTRACT
 
 Analysis of the acid mixture ratio in the lead (Pb) metal deconstruction process in carpet shell’s meat samples (Ruditapes variegatus). In the deconstruction agent HNO3 : HCl (1:3), the average lead metal concentration contained in sweet clam meat is 4.6305 ± 1.066 mg/kg and for the HNO3 : H2SO4 (3:1), the average lead metal concentration contained in the same sweet clam meat was 5.6516 ± 2.556 mg/kg. Statistical test results showed no significant difference in the dissolving power of the acid mixture HNO3 : HCl (1:3) and HNO3 acid mixture: H2SO4 (3:1) as seen from the p>0.005 value, so both the HNO3 acid mixture: HCl (1:3) and HNO3 acid mixture: H2SO4 (3:1) can be used to deconstruct Pb metal in sweet clam meat (Ruditapes variegatus) because there is no significant difference in the two acid mixtures.

Systematic bioprospection for cellulolytic actinomycetes in the Chihuahuan Desert: isolation and enzymatic profiling.

The quest for microbial cellulases has intensified as a response to global challenges in biofuel production. The efficient deconstruction of lignocellulosic biomass holds promise for generating valuable products in various industries such as food, textile, and detergents. This article presents a systematic bioprospection aimed at isolating actinomycetes with exceptional cellulose deconstruction capabilities. Our methodology explored the biodiverse oligotrophic region of Cuatro Cienegas, Coahuila, within the Chihuahuan Desert. Among the evaluated actinomycetes collection, 78% exhibited cellulolytic activity. Through a meticulous screening process based on enzymatic index evaluation, we identified a highly cellulolytic Streptomyces strain for further investigation. Submerged fermentation of this strain revealed an endoglucanase enzymatic activity of 149 U/mg. Genomic analysis of strain Streptomyces sp. STCH565-A revealed unique configurations of carbohydrate-active enzyme (CAZyme) genes, underscoring its potential for lignocellulosic bioconversion applications. These findings not only highlight the significance of the Chihuahuan Desert as a rich source of cellulolytic microorganisms but also offer insights into the systematic exploration and selection of high-performing cellulolytic microorganisms for application in diverse environmental contexts. In conclusion, our bioprospecting study lays a foundation for harnessing the cellulolytic potential of actinomycetes from the Chihuahuan Desert, with implications for advancing cellulose deconstruction processes in various industries. The findings can serve as a blueprint for future bioprospecting efforts in different regions, facilitating the targeted discovery of microorganisms with exceptional cellulosic deconstruction capabilities.

Decolonising knowledge production: the experience of the Syrian Female Journalists Network (SFJN)

ABSTRACT This article delves into the Syrian Female Journalists Network’s (SFJN) approach to decolonise knowledge production, focusing on a multi-faceted deconstructive framework. Through an examination of our analytic and deconstructive process of media language and discourse, our methodology centres on identifying and challenging prevailing patriarchal and colonial power dynamics and binaries within language, particularly in the Syrian media context. Furthermore, our article addresses the transformative role of language in collectively contesting colonial structures through translation and meaning-making processes. Additionally, the article underscores the utilisation of self-identification as a feminist decolonial strategy, emphasising its role in dismantling fixed identity categories and amplifying marginalised voices. Furthermore, it highlights the significance of accountability towards targeted communities by fostering inclusivity, securing access to knowledge, and validating diverse perspectives. Ultimately, this article offers an insight into SFJN’s nuanced approach of decolonising knowledge.

Austrian national identity in the centre-periphery model

ABSTRACT This article deals with the question of Austrian national identity, seen as a case study set within the theoretical frameworks of the centre-periphery model, and in particular, the theories of cultural emancipation of a periphery from the preponderance of a centre. The article examines , firstly, the unequal partnership between Germany and Austria, whose roots are to be found in the rivalry between the Habsburgs and Hohenzollerns, and, secondly, the way Austria invented its concept of a cultural centre after 1945. Finally, emphasis is put on selected political, cultural, and social phenomena, as well as processes that have happened since the 1960s, which question the traditional image of Austria. The salient element of this deconstruction process is by means of unearthing Austria’s memory of the Nazi past, which facilitates the emergence of a critical culture of remembrance and undermines the artificial post-war construct of Austrian national identity.

Towards controlled semi-autonomous deconstruction

The automation of deconstruction processes presents unique difficulties due to the harsh working conditions involved. In this research, we aim to address these limitations by advancing the teleoperated machine, BROKK 170, toward a developed semi-autonomous concept. We propose a framework for robot-assisted deconstruction, exploring the communication and sensing systems of the prototype deconstruction robot, along with its capabilities. Additionally, field tests are conducted to evaluate the performance of the proposed approach in real-world scenarios. The potentials and limitations drawn from these initial results are discussed.

THE DECONSTRUCTION IN THE SHORT STORY JIMAT SERO BY EKA KURNIAWAN

"Jimat Sero" is one of Eka Kurniawan's short stories in the collection of short stories Cinta Tak Ada Mati in 2018. This paper will use deconstruction to examine the ideology of the text and describe the results of its dissemination in the text. This paper uses Jacques Derrida's deconstruction theory. The method used is content analysis with double reading. The results contain two main points; First, the ideology of the text from the identification of metaphysical hierarchies, binary oppositions, and undecidable elements in the text. Second, dissemination of the results of the deconstruction process. The result of the text's ideology is the curious days experienced by Aku after being given an amulet by Rohman. The results of the dissemination in the text are; 1) Aku reflects the generality of society towards mystical things, 2) Rohman's character is an abortion of village people who consider the city as the primary goal of success.

Design for adaptability and disassembly: guidelines for building deconstruction

Purpose Design for adaptability and disassembly (DfAD) is an effective method to reduce construction and demolition waste generation, landfill loads and greenhouse gas generation; preserve natural resources; and increase environmental awareness in the construction industry. However, it is an underexplored strategy due to a lack of information about projects and a set of agreed guidelines to guide buildings deconstruction. This study aims to understand how DfAD can support the sector’s transition toward circularity. Design/methodology/approach Through an integrative literature review, this study analyzed the current publications and terminologies used, identified the main themes discussed and described the key criteria for integrating deconstruction in the building design stage. Findings The results showed that the term DfAD encompasses different ecodesign strategies and is concentrated in six major thematic categories (design and construction principles, tools for DfAD, components and connections for DfAD, barriers, drivers and guidelines for DfAD, existing building stock potential and selective deconstruction process). In total, 60 criteria were presented to guide the deconstruction of buildings, emphasizing standardization, modularization and prefabrication of materials and components as fundamental requirements. Originality/value The study highlighted the need to expand the knowledge and training of the design team, establish public policies and tax incentives and develop tools, methods, and circular indicators to enable the implementation of deconstruction strategies for buildings.
