In debates about recycling and the circular economy, the role of existing organisations that already facilitate the circulation of materials through society can be neglected. Indeed, the social enterprise sector may currently be more significant than the commercial waste management sector in facilitating the circular economy within Australia. Drawing on interviews with organisations involved in collecting and reprocessing used electronics and scrap metal in Australia, the authors detail some of the synergies and tensions between the social enterprises and commercial organisations that have emerged as recycling gains traction through government policy and various forms of product stewardship. The authors conclude with suggestions for policy and governance approaches most likely to facilitate productive and perhaps symbiotic relationships between the two sectors in the future.

The Waste Management Hierarchy is a well-established framework for conceptualizing the spectrum of desirable behaviours to manage, reduce and avoid waste. To date, research relating to the householder behaviours on the Waste Management Hierarchy has primarily focused on the lower order disposal and recycling behaviours, reflecting the areas of historical policy attention. Recently, however, policy focus has shifted to ‘higher order’ behaviours such as reuse and avoidance, in line with Circular Economy thinking. To address the measurement gap, this chapter develops and tests a battery of householder waste behaviour measures across the entire waste hierarchy. The battery was piloted with 573 South Australian householders, where the ‘higher’ order waste behaviours are more likely to be displayed as the Waste Hierarchy has been embedded in waste policy directives for many years. Findings empirically validate the Waste Management Hierarchy, deliver a quantified benchmark of the prevalence of behaviours across its spectrum and explore the underlying motives driving pro-environmental behaviour.

This contribution aims to provide multidisciplinary knowledge on the effectiveness of experimenting with nature-based solutions (NBS) for urban regeneration policy, planning, design, and governance. Specifically, the following research questions have been investigated through a cross-case study conducted in the cities of Barcelona, Copenhagen, and Marseille: What is the wider contribution of NBS for urban generation? What are the added value, the strengths, and the weaknesses of urban regeneration programs leveraging on NBS? and What is the upscale potential of NBS within selected urban regeneration programs in Europe in a post–COVID-19 scenario? The focus of the research is to create an understanding of what type of NBS development process can bring forward sustainable urban development, the different stakeholders that might be involved, the nature of their involvement, and the relationship between the actors. Three cities have been identified as most informative to explore how NBS can be valid alternatives for buildings, districts, and infrastructures redevelopment, as a starting point to foster urban resilience: Copenhagen, Barcelona, and Marseille. The results of the conducted study reveal future opportunities as well as challenges with respect to possible integrated strategies for successful codesigned and cocreated NBS for urban regeneration, especially in light of the revised post–COVID-19 pandemic urban agendas focusing on health and well-being of citizens as well as on more balanced and resilient urban built environments.

Biosolids, the residual solids from wastewater treatment operations and once considered a waste product by the industry, are now becoming increasingly recognised as a multifunctional resource with growing opportunities for marketable use. This shift in attitude towards biosolids management is spurred on by increasing volatility in energy, fertilizer and commodity markets as well as moves by the global community towards mitigating global warming and the effects of climate change. This chapter will provide an overview of current global biosolids practices (paired with a number of Australian examples) as well as discuss potential future uses of biosolids. Additionally, present and future risks and opportunities of biosolids use are highlighted, including potential policy implications.

Having considered various types of pedagogy as well as technology affordances and multimedia learning principles, this chapter focuses on issues surrounding the representation and sharing of content using technology. Anderson & Krathwohl’s (2001) Taxonomy of Learning, Teaching and Assessing is examined as a means of conceptualizing different types of thinking processes in a way that can be applied across discipline areas. The representational requirements of different subject areas (English, mathematics, science, history, geography, and computing) are explored by means of examples, with reference to the role of technology and the range of possible tasks that may be utilized. Assessment issues as they relate to the representation of content are also considered. The broader contextual shift toward open education and sharing is discussed, including key drivers such as learning object repositories, open educational resources, Creative Commons licensing, and massive open online courses.

This chapter identifies the five new roles that are critical to establishing and sustaining a knowledge preservation and curation practice. For each role, the authors describe fundamental responsibilities and competencies. Two of the roles support knowledge preservation, including business knowledge analyst and specialized knowledge preservationist. Three of the roles support knowledge curation including business interlocutor/translator, knowledge curator, and knowledge asset developer. Each role faces peculiar challenges in a dynamic and chaotic knowledge economy.

The production of waste creates both direct and indirect environmental impacts. A range of strategies are available to reduce the generation of waste by industry and households, and to select waste treatment approaches that minimise environmental harm. However, evaluating these strategies requires reliable and detailed data on waste production and treatment. Unfortunately, published Australian waste data are typically highly aggregated, published by a variety of entities in different formats and do not form a complete time-series. We demonstrate a technique for constructing a multi-regional waste supply-use (MRWSU) framework for Australia using information from numerous waste data sources. This is the first subnational waste input–output framework to be constructed for Australia. We construct the framework using the Industrial Ecology Virtual Laboratory (IELab), a cloud-hosted computational platform for building Australian multiregional input–output tables. The structure of the framework complies with the System of Environmental-Economic Accounting (SEEA). We demonstrate the use of the MRWSU framework by calculating waste ‘footprints’ that enumerate the full domestic supply chain waste production for Australian consumers.

Contemporary literature reveals that, to date, the poultry livestock sector has not received sufficient research attention. This particular industry suffers from unstructured supply chain practices, lack of awareness of the implications of the sustainability concept and failure to recycle poultry wastes. The current research thus attempts to develop an integrated supply chain model in the context of poultry industry in Bangladesh. The study considers both sustainability and supply chain issues in order to incorporate them in the poultry supply chain. By placing the forward and reverse supply chains in a single framework, existing problems can be resolved to gain economic, social and environmental benefits, which will be more sustainable than the present practices.

The theoretical underpinning of this research is ‘sustainability’ and the ‘supply chain processes’ in order to examine possible improvements in the poultry production process along with waste management. The research adopts the positivist paradigm and ‘design science’ methods with the support of system dynamics (SD) and the case study methods. Initially, a mental model is developed followed by the causal loop diagram based on in-depth interviews, focus group discussions and observation techniques. The causal model helps to understand the linkages between the associated variables for each issue. Finally, the causal loop diagram is transformed into a stock and flow (quantitative) model, which is a prerequisite for SD-based simulation modelling. A decision support system (DSS) is then developed to analyse the complex decision-making process along the supply chains.

The findings reveal that integration of the supply chain can bring economic, social and environmental sustainability along with a structured production process. It is also observed that the poultry industry can apply the model outcomes in the real-life practices with minor adjustments. This present research has both theoretical and practical implications. The proposed model’s unique characteristics in mitigating the existing problems are supported by the sustainability and supply chain theories. As for practical implications, the poultry industry in Bangladesh can follow the proposed supply chain structure (as par the research model) and test various policies via simulation prior to its application. Positive outcomes of the simulation study may provide enough confidence to implement the desired changes within the industry and their supply chain networks.
