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.

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.

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.

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.

This study explores the significance and implementation priorities for Digital Product Passports (DPP) in the context of building renovation projects. It aims to reveal bottlenecks and how a data-driven workflow bridges the DPP understanding/implementation gap, facilitating the transition towards practices aligned with the EU Green Deal goals.

A mixed-methods embedded design was employed for a real-case study exploration. Desk research and field observations ground the two-level analysis combining project documentation, namely the Bill of Quantities (BoQ), with different criteria in digitalisation and sustainability, such as economic ratio, 3D modelling, waste management, hazards, energy performance and facility management. All results were interpreted from the DPP lens.

The analysis revealed a system for identifying building products representing a significant part of the renovation budget. About 11 priority DPPs were found. Some are crucial for both the deconstruction and construction phases, highlighting the need for an incremental and strategic approach to DPP implementation.

The study is limited to a single case study. Constraints are minimised given the sample's archetype representativeness. The outcomes introduce the need for strategic thinking for incremental DPP implementation. Future research will explore additional criteria and cases.

The research has resulted in a classification framework for DPPs' significance and priority, which is provided with case results. The outcome of the framework provides views on concept alignment to make the implementation in construction more straightforward. Its practical use can be replicated in other projects, emphasizing the importance of data structure and management for the circular economy.

This paper aims to investigate the relationship between academia and society focusing on how technical universities perform Third Mission (TM) to promote knowledge outside the academic environment producing multiple benefits.

This investigation is performed through the conceptual approach. The theoretical background of the TM is explored through scientific literature review. It analyses a selected pool of experiences focused on Environmental and Sustainable Education (ESE). The study identifies significant aspects of two specific case studies, designed and implemented by the authors.

Outcomes show opportunities and limitations in the application of ESE on behalf of technical academia. The study suggests solutions, precautions and systemic changes to promote ESE for childhood as TM activity in technical engineering academia. These recommendations can be useful for policymakers to set academic goals and plan the strategic management of teaching, research and TM.

The paper focuses on the role of technical engineering universities and criticalities faced by academics to foster and perform ESE. Future perspectives aim to create new opportunities to strengthen the social impact of scientific and technical research by building bridges with childhood education.

Previous research has evidenced that communication design students wish to engage further with sustainable practices but struggle to understand how (Newton and Ellis, HER conference 2023). Whereas other design disciplines (fashion, product, furniture) can often focus on a “physical” output, communication design embraces multiple outcomes, distributed throughout a range of platforms, representing an area of industry and study which can prove difficult to define. This study aims to add further clarity as to how students consider sustainability aligned to their practice.

Previous focus group research sought to uncover how communication design students implicitly consider “sustainability”, uncovering that their knowledge is limited. Suggestions from participants emphasised that it was the role of the institution, not the student, to fully integrate sustainability into practice and to define methods they can deploy. This paper notes a subsequent workshop conducted with 33 Level 5 undergraduate students asking them to reflect on Sustainable Development Goals (SDGs) 12/13 in relation to meaningful practice and institutional responsibility.

Workshops demonstrated the need to engage with sustainable thinking throughout every stage of development. It is clear that students demand more from academic staff at programme level, and from the institution at large, to provide further solutions to sustainability concerns which are relevant to their specific practice.

Discussion surrounding pedagogical practice across communication design lacks interrogation, yet the discipline represents a significant aspect of both design and contemporary society. It is paramount that methods for reinforcing implicit engagement with sustainable best practice within students, their development and their future beyond university are therefore developed.

This study aims to investigate how the adoption of sustainable manufacturing practices by companies can positively impact their reputation and environmental performance. Additionally, it aims to explore the specific relationships between these factors within the unique context of manufacturing companies in Tunisia.

The research uses an online questionnaire survey methodology targeted at manufacturing companies in Tunisia. This approach provides detailed insights into the current landscape of sustainable manufacturing practices within the region.

The study underscores the increasing significance of sustainable manufacturing practices for companies striving to align with environmental sustainability while meeting stakeholder expectations. It reveals that embracing these practices can indeed yield favorable impacts on both a company’s environmental performance and its overall reputation.

While the study sheds light on the relationships between sustainable practices, environmental performance and reputation, it acknowledges certain limitations. These limitations might include the scope of the survey, potential biases in responses or constraints within the Tunisian manufacturing context, impacting the generalizability of findings.

This research holds unique value by offering insights into the complex interplay between sustainable manufacturing practices, environmental performance and corporate reputation in a developing country context like Tunisia. The study contributes to a deeper understanding of these dynamics, benefiting both academia and industry practitioners interested in fostering sustainability within the manufacturing sector.

The integration of sustainability, performance measurement and new product development (NPD) is key for aligning environmental and social objectives with business strategies. While previous research has initiated proposals for integrating sustainability into NPD or incorporating sustainability into corporate measurement systems, there is a notable deficiency in studies that comprehensively integrate these three perspectives. In this sense, this study proposes a performance framework (PF) to integrate sustainability performance indicators (PIs) into the measurement system considering the company’s NPD phases.

The PF was developed through a literature review and action research (AR). This resulting PF was positively evaluated by the practitioners in the company.

First, the review enabled the synthesis of an initial conceptual PF with 188 sustainability PIs and a five-step procedure. Then, the empirical results of the AR led to a new PF that presents the systematisation of the PIs database and a practice-based seven-stage approach.

This action-oriented research limits the extent to which this study’s findings can be generalised. Future research should apply the PF in different research designs to produce managerially relevant knowledge.

This PF may provide managers with actionable knowledge that best supports the measurement system integration with sustainability PIs considering the NPD phases.

Integrating sustainability, performance measurement and the NPD has been recognised as critical for supporting decision-making concerning the impact of processes and products. Compared with previous frameworks, the proposed PF extends the existing literature by introducing a systematised PIs database and a novel procedure for integrating sustainability measurement throughout the NDP.

This study aims to analyze the implications of the recent European Union Regulation 2023/1542 on the circular economy and stakeholder strategies within the electric vehicle lithium-ion battery (EV-LIB) sector. It aims to explain the policy intentions, recommend practical strategies for stakeholders and examine how the new regulation exerts pressure on stakeholders to transition from older directives to more sustainable practices and operational standards, while also highlighting policy gaps.

The research employs a dual-method approach, combining text analysis of EU legislation with semi-structured interviews of industry stakeholders. This methodology allows for a comprehensive understanding of the regulatory impacts by integrating legislative intent with practical, on-the-ground insights from key players in the EV-LIB sector.

Our findings show that the three aggregated dimensions of operational sustainability, R&D and new technologies and collaborative dynamics are the key dynamics underlying the intended outcomes. The findings also highlight the policy’s historical development, the stakeholder categories, the implications for each and practical recommendations in responding to the policy requirements. Additionally, the findings identify policy gaps, such as weak incentives and broad economic operator classifications, with examples from international markets. The regulation creates proactive stakeholders driving innovation and collaboration and reactive ones adapting to changes, where static implicit implications may affect their viability by imposing unequal burdens.

To the best of the authors’ knowledge, this paper is the first to analyze the new EU Regulation 2023/1542, offering novel insights into the strategic responses required by stakeholders to adapt to the regulatory pressures. By focusing on the latest regulatory framework and its practical implications, the study bridges the gap between policy and practice, providing valuable guidance for industry players navigating the evolving regulatory environment.

Heterogeneous and micro-structured materials have been the object of multiscale and homogenization techniques aimed at recognizing the elastic properties of the equivalent continuum. The proposed investigation deals with the mechanical characterization of the heterogeneous material structured metamaterials through analyzing the ultimate strength using the limit analysis of the Representative Volume Element (RVE). To get the desired material strength, a novel finite element formulation based on the derivation of self-equilibrated solutions through the finite elements devoted to calculating the lower bound theorem has been implemented together with the limit analysis in Melàn’s formulation.

The finite element formulation is based on discrete mapping of Volterra dislocations in the structure using isoparametric representation. Using standard finite element techniques, the linear operator V, which relates the self-equilibrated internal solicitation to displacement-like nodal parameters, has been built through finite element discretization of displacement and strain.

The proposed work presented an elastic homogenization of the mechanical properties of an elementary cell with a geometry known in the literature, the isotropic truss. The matrix of elastic constants was calculated by subjecting the RVE to numerical load tests, simulated with a commercial FEM calculation code. This step showed the dependence of the isotropy properties, verified with Zener theory, on the density of the RVE. The isotropy condition of the material is only achieved for certain section ratios between body-centered cubic (BCC) and face-centered cubic (FCC), neglecting flexural effects at the nodes. The density that satisfies Zener’s conditions represents the isotropic geomatics of the isotropic truss.

For the isotropic case, the VFEM procedure was used to evaluate the isotropy of the limit domain and was compared with the Mises–Schleicher limit domain. The evaluation of residual ductility and dissipation energy allowed a measurement parameter for the limit anisotropy to be defined. The novelty of the proposal consisted in the formulation of both the linearized and the nonlinear limit locus of the material; hence, it furnished the starting point for further limit analysis of the structures whose elementary volume has been described through the proposed approach.

This study aims to improve the mechanical properties of an object produced by fused deposition modelling with high-grade polymer.

The study uses an ensembled surrogate-assisted evolutionary algorithm (SAEA) to optimize the process parameters for example, layer height, print speed, print direction and nozzle temperature for enhancing the mechanical properties of temperature-sensitive high-grade polymer poly-ether-ether-ketone (PEEK) in fused deposition modelling (FDM) 3D printing while considering print time as one of the important parameter. These models are integrated with an evolutionary algorithm to efficiently explore parameter space. The optimized parameters from the SAEA approach are compared with those obtained using the Gray Relational Analysis (GRA) Taguchi method serving as a benchmark. Later, the study also highlights the significant role of print direction in optimizing the mechanical properties of FDM 3D printed PEEK.

With the use of ensemble learning-based SAEA, one can successfully maximize the ultimate stress and percentage elongation with minimum print time. SAEA-based solution has 28.86% higher ultimate stress, 66.95% lower percentage of elongation and 7.14% lower print time in comparison to the benchmark result (GRA Taguchi method). Also, the results from the experimental investigation indicate that the print direction has a greater role in deciding the optimum value of mechanical properties for FDM 3D printed high-grade thermoplastic PEEK polymer.

This study is valid for the parameter ranges, which are defined to conduct the experimentation.

This study has been conducted on the basis of taking only a few important process parameters as per the literatures and available scope of the study; however, there are many other parameters, e.g. wall thickness, road width, print orientation, fill pattern, roller speed, retraction, etc. which can be included to make a more comprehensive investigation and accuracy of the results for practical implementation.

This study deploys a novel meta-model-based optimization approach for enhancing the mechanical properties of high-grade thermoplastic polymers, which is rarely available in the published literature in the research domain.

This study evaluates the implementation of circular economy (CE) design strategies in mass timber construction to identify knowledge gaps and define crucial future research areas for promoting CE design adoption in this field.

A two-stage systematic literature review (SLR) was conducted to, first, identify CE design strategies applicable to the construction industry and then investigate the current state of CE design research in mass timber construction. Scopus and Web of Science databases were searched for relevant literature. In total, 52 peer-reviewed journal articles published between 2016 and 2023 were shortlisted. Descriptive and thematic analyses were then employed to analyse and synthesise the relevant literature.

Seven CE design strategies were identified in the first stage of the SLR. The second stage of the SLR revealed limited research on CE design strategies in mass timber construction. Several research problems were identified, including a lack of suitable connectors for the deconstruction phase, durability concerns, insufficient knowledge of CE design methods, lack of knowledge and education about mass timber construction, missing actors within the value chain, higher cost, an underdeveloped market and inadequate regulatory requirements. These findings highlighted the future research directions to foster CE design adoption in mass timber construction.

The study systematically identifies existing knowledge on the application of CE design strategies in mass timber construction. Moreover, it presents a conceptual framework that links current research problems to future research directions across technical, social, economic and regulatory categories, thereby advancing CE practice in mass timber construction.
