Abstract: The UN Sustainable Development Goals (SDGs) offer a framework for a better future by focusing on people, planet, prosperity, peace and partnerships. SDGs directly relating to the built environment are SDG 11, SDG 9 and SDG 12. The SDGs do not explicitly mention circular thinking or practices. Yet, the principles underpinning sustainability and circularity are the same, especially those focusing on resource efficiency and conservation. The aim of this paper is to map the SDGs against circular built environment indicators in the Global South. In doing so, not only is the alignment between the National Determined Contributions (NDCs) and the built environment established, but the significant position that the built environment plays in the rapidly growing cities of the Global South is also strongly supported. Using secondary research, this paper first investigates the primary and secondary SDG indicators for achieving circular built environments by the One Planet Network’s Sustainable Buildings and Construction programme. This is then validated by undertaking workshops with experts in the Global South to determine an interim set of SDG indicators relate to circular economy such as local jobs, design considering climate mitigation, resilience and adaptation and such other indicators. The paper recommends priority indicators for achieving circular built environments in the Global South and suggests further research needs to be undertaken to finalise these indicators.

Abstract: One Planet Sustainable Buildings and Construction Programme (SBC), led by the Ministry of the Environment, Finland and co-led by RMIT University and UN Environment Programme was initiated in 2015. Work on circular built environments commenced in the second iteration of the programme’s work plan. SBC was the first global programme that worked on circularity and responsibly sourced materials in the buildings and construction sector. In 2020, the SBC programme published a range of reports focusing on the state of play for circular built environments across specific regions, tied together with a global report. The present focus of the programme is on Africa, Asia and Latin America, where case studies are collected following a common framework.These case studies together with a global survey provide reliable performance data for responsibly sourced building materials in the Global South. The underpinning premise through this process is to support related SDGs across the social, environmental, and economic considerations and enable countries to achieve their targets under the Paris Agreement. This paper presents key findings from this study, largely derived through case studies in the Global South. The results show that not all stages of the building life cycle are addressed through local ex les.

Abstract: Circular economy thinking encourages society to adopt sustainable patterns of consumption and production. This basic principle aligns with the objectives of the United Nations’ Sustainable Development Goals (SDGs), which include improving human welfare through equal access to drinking water and sanitation together with reliable, sustainable, and modern energy supplies for all. Traditional approaches to delivering public utility services have been rooted within the Baconian view that the environment is a pool of resources that exist for the betterment of humankind. Whilst this tradition has delivered water supply, sanitation, electricity generation, and waste management services, that have improved the lives of countless humans, the provision of these services largely relies on business models and technologies that have had significant adverse impact upon the natural environment. To inform the development of new sustainable business models, this paper explores circularity concepts from the perspective of decision makers and actors responsible for the delivery of public utility infrastructure. Through a review of the secondary literature, this paper examines core circular economy principles and maps these against fundamental business model elements to synthesise a framework of precursor considerations for future business models. This framework has potential application in testing the extent to which existing business models in the utility sector support the transition to a circular economy and how current business models can be adapted to assist the achievement of sustainable development.

Abstract: This paper aims to highlight the localised shelter solutions to fulfil adequate and disaster resilient housing needs of urban informal settlers of Honiara, the capital city of Solomon Islands, in a way that is sensitive to their unique challenges, values and aspirations, is gender- and disability-inclusive, and considers housing from the complete lifecycle of a disaster (pre-, during- and post-). Qualitative data was gathered through empirical research through five community workshops at five hotspot settlements, two stakeholder workshops and a stakeholder interview. Semi-structured questions as well as photographs of housing and settlement were used for data collection. With an emphasis on self-recovery, the identified shelter needs were then matched with the roles and responsibilities of the Government to support a process of “assisted” self-preparedness and recovery. The output of the research was the Solomon Islands Shelter Guide. This paper draws from the Guide to present some of the findings. One of the key findings was an emphasis on shelter self-preparedness and self-recovery. However, in order for them to do that, they needed a combination of assistance – technical knowledge, materials and financial support – which is tailored to their settlement’s specific needs and based on hazard damage assessment. While the Guide provides one form of the assistance (i.e. technical), this paper is a call for action from the Solomon Islands Government and shelter responders to fulfil the rest of the community needs for shelter adequacy. The paper contributes to existing scholarship on shelter after disasters by adding “assisted” in front of self-recovery, in line with the limited access to resources by the most vulnerable to recover, despite housing being” a human right and definition of adequate housing (UN-Habitat, 2015, 2021), which includes freedom of choice, entitlements and meeting minimum adequacy criteria. There are many implications of this research. Since the publication of the Shelter Guide, there is excitement among most humanitarian and development agencies, government authorities and the local communities in Honiara. The Guide forms the first step in contributing to identified needs and strengthening community capacities to self-build, self-recover or self-retrofit one’s house based on their own choice of materials, design, social and economic circumstance. However, it provides one of the three elements identified as needs by the communities, as i) technical guidance, and a kit-of parts for multi-hazard safe housing, ii) financial and economic assistance and iii) a political voice or being supported and heard by the government. The research team are working with the same five urban informal communities in 2022–2023 to develop and operationalise local disaster plans (in partnership with local non-government organisations), capacity-building activities and translation of the Shelter Guide into technical posters (for local builders) and graphic novel in local pidgin language, as part of the Climate Resilient Honiara project (funded by the United Nations framework convention on climate change (UNFCCC) Adaptation fund and administered by UN-Habitat). In the longer term it would be worth evaluating the practical implications of the Guide or to examine whether the proposed socio-technical and governance guidance will find roots in the local culture. While the Guide adhered to internationally agreed concepts of self-recovery, incremental shelter and core space, it contributes to existing scholarship on shelter after disasters by adding “assisted” in front of self-recovery, in line with housing as a human right and adequate housing (UN-Habitat, 2015, 2021), including freedom of choice, entitlements and meet minimum adequacy criteria, all of which require materials and financial assistance by the relevant in-country authorities.

Abstract: The circular economy (CE) is emerging as a solution for a thriving economy within regional and planetary boundaries for environment and social justice. CE is multifaceted with interconnected processes and therefore rather difficult to assess comprehensively. This paper reviewed the corpus of macro-level CE assessments, to find the best practices in CE assessments of regions scaling from neighborhoods to planetary. The extensive content analysis on the corpus of 165 studies used a novel mixed methods of meta-analysis, taxonomy and integrative review. This review investigates the comprehensiveness of CE assessments. Findings include three types of CE performance monitoring, four types of resource clustering, five scales, and a 5-step procedure to evaluate CE. CE can be monitored on: (a) absolute performance, quantifying economic resource-input, stock and waste-output (b) efficiency performance, monitoring the optimization of CE processes similar to recycling, reuse, or even sharing and virtualizing (c) policy performance to monitor strategies from regional stakeholders. Resource clustering can create hierarchies by metrics, uses, system-boundaries, or emergy. Identified scales are: XL for the planet L for continents M for large provinces, states and smaller countries S for cities and, XS for neighborhoods. Scales assist in comparing and benchmarking, but are also required for a proposed policy of localizing CE. This review found the ReSOLVE-framework as relatively comprehensive on CE processes. Also, multiple knowledge gaps were identified among resources, processes and regions. This review aids CE knowledge accumulation across regions and scales, to accelerate implementing the CE.

Abstract: Lithium-ion batteries have become a crucial part of the energy supply chain for transportation (in electric vehicles) and renewable energy storage systems. Recycling is considered one of the most effective ways for recovering the materials for spent LIB streams and circulating the material in the critical supply chain. However, few review articles have been published in the research domain of recycling and the circular economy, with most mainly focusing on either recycling methods or the challenges and opportunities in the circular economy for spent LIBs. This paper reviewed 93 articles (66 original research articles and 27 review articles) identified in the Web of Science core collection database. The study showed that publications in the area are increasing exponentially, with many focusing on recycling and recovery-related issues policy and regulatory affairs received less attention than recycling. Most of the studies were experiments followed by evaluation and planning (as per the categorization made). Pre-treatment processes were widely discussed, which is a critical part of hydrometallurgy and direct physical recycling (DPR). DPR is a promising recycling technique that requires further attention. Some of the issues that require further consideration include a techno-economic assessment of the recycling process, safe reverse logistics, a global EV assessment revealing material recovery potential, and a lifecycle assessment of experiments processes (both in the hydrometallurgical and pyrometallurgical processes). Furthermore, the application of the circular business model and associated stakeholders’ engagement, clear and definitive policy guidelines, extended producer responsibility implications, and material tracking, and identification deserve further focus. This study presents several future research directions that would be useful for academics and policymakers taking necessary steps such as product design, integrated recycling techniques, intra-industry stakeholder cooperation, business model development, techno-economic analysis, and others towards achieving a circular economy in the LIB value chain.

Abstract: The triple bottom line (TBL) principle encompasses the idea of continued economic and social well-being with minimal or reduced environmental pressure. However, in construction projects, the integration of social, economic, and environmental dimensions from the TBL perspective remains challenging. Green building rating tools/schemes, such as Green Rating for Integrated Habitat Assessment (GRIHA), Leadership in Energy and Environment Design (LEED), Building Research Establishment Environment Assessment (BREEAM), and their criteria, which serve as a yardstick in ensuring sustainability based practices and outcomes, are also left wanting. These green building rating tools/schemes not only fail to comprehensively evaluate the three dimensions (social, economic, and environment) and interaction therewith, but also lack in capturing a life cycle approach towards sustainability. Therefore, this study intends to address the aforementioned challenges. The first part of this study presents the concept of sustainable construction as a system of well-being decoupling and impact decoupling. Findings in the first part of this study provide a rationale for developing a methodological framework that not only encapsulates a TBL based life cycle approach to sustainability assessment in construction, but also evaluates interactions among social and economic well-being, and environmental pressure. In methodological framework development, two decoupling indices were developed, namely, the phase well-being decoupling index (PWBDIK) and phase impact decoupling index (PIDIK). PWBDIK and PIDIK support the evaluation of interdependence among social and economic well-being, and the environmental pressure associated with construction projects in different life cycle phases. The calculation underpinning the proposed framework was illustrated using three hypothetical cases by adopting criteria from GRIHA Precertification and GRIHA v.2019 schemes. The results of these cases depict how the interactions among different dimensions (social, economic, and environment) vary as they move from one phase to another phase in a life cycle. The methodological framework developed in this study can be tailored to suit the sustainability assessment requirements for different phases and typologies of construction in the future.

Abstract: – This paper aims to evaluate how transformative learning is key to innovating sustainability education in the built environment in the region’s universities, in addition to reporting on the research project undertaken to integrate sustainability thinking and practice into engineering/built environment curricula in Asia-Pacific universities. – The project drew from the experiences of academics in built environment programmes and espoused a collaborative inquiry process wherein the role of the industry was vital. A literature review focusing on sustainability integration into curricula was followed by a workshop which brought together academic and industry participants. – The general direction of education for sustainability is moving increasingly towards integration and innovation. However, the slow progress of integration of sustainability in the built environment curricula may have been due in part to the outcome ractice-led approach of built environment education, which is the hallmark of the discipline and lends to a largely discipline-based curriculum framework. – The project focused only on the curricula of university programmes and courses taught in the participating Asia-Pacific universities and institutions. – This paper highlights how the framework for the proposed curriculum guide focusing primarily on built environment programmes and courses can provide guidance for potential application in other higher education institutions. – Much is written about embedding sustainability and education in built environment curricula. However, little analysis, application and collaborative work in Asia-Pacific universities have taken place. This paper considers the value of transformative learning in the innovation of the predominantly discipline-based engineering/built environment programmes for sustainability.

Abstract: With increased climate-related risks and natural disasters, impacts on infrastructure assets are intensifying. As the need for adaptation actions increase, how finance is used to enable adaptation plays a vital role in the resilience of infrastructure. This research aims to understand how infrastructure adaptation measures are carried out, focusing on how financing is used to aid such efforts. Exploratory interviews with infrastructure and finance practitioners from a broad range of organisations were conducted to understand the dynamics of how infrastructure adaptation occurs. The findings reveal that infrastructure agencies conduct adaptation activities to maintain the serviceability of assets under climate change risks, with most climate financing targeting mitigation rather than adaptation. Most actions are taken at in idual asset or agency level with little collaboration across agencies and sectors. The results illustrate a need for a more holistic, systems-level approach to adaptation across the infrastructure sector in Australia.

Abstract: Buildings are one of the highest emitters of greenhouse gases globally. To reduce the detrimental effects of buildings on the environment and recognise their potential for emissions reductions, a transition towards sustainable building solutions has been observed globally. This trend and the associated benefits have been discussed and argued for more than three decades now. However, the impacts of sustainable buildings are yet to be demonstrated at macro, meso, and micro levels in the community, as the actual versus expected performance of such buildings are still being questioned. Consequently, this entry discusses the concepts underpinning sustainable buildings outlining the drivers and practices to achieve sustainable built environment solutions from the design to operation stage using university buildings as a case study. The chapter also recommends evidence-based solutions on understanding the actual and perceived gaps to achieve expected performance using “Green Star” rated academic buildings in Australia.

Abstract: / The relevant literature is abound with different definitions for sustainability, but the most meaningful definition is set within an evolutionary framework. Mechanistic and evolutionary frameworks for sustainable development are discussed. Evolution and adaptation are characteristics of complex adaptive systems, and a new understanding of sustainable development can be gleaned by using the complex adaptive systems framework. This approach to sustainable development issues implicitly requires proactive involvement by the public. This paper supports that bottom-up participation needs to be nurtured. Appropriate processes to enable participation need to be designed and implemented.

Abstract: Circular business models (CBMs) are integral to the concept of the circular economy (CE). The aims of the study are to (1) redesign a canvas for CBM and (2) validate it through a single case study. The developed canvas is called the “Circular Business Model Value Dimension Canvas”. For the validation, a semi-structured interview with a social enterprise (SE) operating in hybrid CBM (i.e., resource recovery, sharing platform, and product use extension) in Australia has been performed. Results showed that a successful hybrid CBM for a SE necessitates the integration of forward and reverse supply chains through partnerships with new product retailers and resource recovery companies. Other important factors include the presence of physical stores, an effective product return strategy, initial funding support from the government, the employment of young in iduals with special needs, and the promotion of behavioral change among low-income customer segments. Although the canvas was applied to the enterprise, it can also be applied to other organizations as the canvas integrates all essential components for business modeling. The proposed canvas serves as a supportive tool for CBM innovation (CBMI) and provides a framework for researchers to investigate the CBMI process in organizations transitioning from linear to circular.

Abstract: The circular business model (CBM) is one of the main building blocks of circular economy (CE), and recycling is one of the main strategies for achieving it. CBM literature is currently evolving, and recycling-oriented discussion has been found in a scattered manner. This review article aims to identify critical components of the recycling-focused business model in CE and evaluate potential business and research opportunities in the area. Data collection was undertaken from the Web of Science (WoS) core collection and ScienceDirect database. Results of the study showed that efficiency of municipal solid waste management, reporting mechanism of recyclers cost of recycled materials, the establishment of a plastic hub, implementation of extended producer responsibility, strategic partnership, incentives, and product design were highlighted as critical requirements for efficient recycling operated business models, especially for waste solar PV panels, e-waste, textile waste, and vehicles and battery sector. It also identified the benefits of using recycled materials in reducing carbon footprint, energy consumption, and achieving low environmental impact. Three-dimensional printing, sensor-based RFID tags, digital twins, additive manufacturing, Industry 4.0, and the Internet of Things (IoT) were found as state-of-the-art technological innovations applied to recycling-oriented circular business models. This article provides critical practical solutions for new business model development and indicates vital future research directions along with a conceptual framework development, which would be helpful for policymakers, business entities, and research academics.
