Transboundary movement of waste review: From binary towards a contextual framing.

Multiple cases of toxic waste dumping from the Organisation for Economic Co-operation and Development (OECD) countries to non-OECD countries in the 1980s led to scholarly attention to transboundary waste movements. The Basel Convention was established to provide an international legal framework to tackle such problems in the early 1990s, focusing on hazardous waste. However, the transboundary movement of all waste, not just hazardous waste, remains a societal challenge globally, frequently surfacing as an ethical question on the one hand and a story of resource management/trade on the other. This phenomenon has been studied across disciplines resulting in diverse, scattered and often contested understandings. Despite previous and ongoing efforts, waste production, management and transboundary movements are increasing and are predicted to grow significantly with global social, environmental and economic implications. This literature review uses a research synthesis and problematisation approach to critically analyse the transboundary waste literature since 1985. The findings highlight research trends, the need for data reliability and policy coherence, and the sustainability implications of the phenomenon. One recurring theme in the literature is the reduction of the complex phenomenon involving multiple countries, policies, actors and waste streams into simple opposite narratives, which we called transboundary waste binaries. We have identified and then challenged assumptions behind transboundary waste binaries and discussed the implications of such assumptions on the broader discourse. We have concluded with future research recommendations to look past the transboundary waste binaries towards a nuanced and contextual understanding of transboundary waste flows.

A survey of Circular Economy initiatives in Portuguese central public sector organisations: National outlook for implementation.

The Circular Economy (CE) is generally understood as an opportunity to transform the current unsustainable linear economic system by redesigning the way organisations provide goods and services rethinking how society consumes and uses those resources. In this context, the public sector is mainly recognised as an actor enabling the implementation of a sustainable CE through governmental interventions and policy initiatives. However, there is a lack of studies considering the public sector at an organisational level. CE in organisations includes a wide range of different practices that are important to examine in order to analyse the CE implementation process. Consequently, this study aims to characterise the current state of implementing circular practices and supporting strategies in central public sector organisations. To fulfil this aim, a questionnaire survey was sent to the organisations pertaining to the Portuguese Central Public Administration, as surveys are valuable tools to systematically collect information on various topics. The results demonstrate a relatively low level of implementation. Circular practices such as purchasing remanufactured or used items, using sharing platforms, increasing the efficiency of buildings, adopting green human resources and collaborative initiatives for circularity, and assessing and communicating about CE activities have presented low levels of adoption. At the same time, waste collection for recycling and dematerialisation practices showed good implementation levels. There is, thus, immense potential for further implementation of circularity in central public sector organisations in Portugal. This research contributes to deepening the understanding of the extent to which circular practices are embedded in public sector organisations and identifying the main implementation strengths and weaknesses. This research has the potential to help practitioners and researchers in the transition towards circularity in identifying circular opportunities in their organisations and in building a vision to further implement circularity in public sector organisations.

Negotiating Stakeholder Relationships in a Regional Circular Economy: Discourse Analysis of Multi-scalar Policies and Company Statements from the North of England.

Circular economy (CE) literature discusses the need for cooperation between different stakeholders to promote a CE; there is also an assumption regarding the benefits of loop closing on a local or regional scale. However, the potentially conflicting priorities, understandings, and expectations of the stakeholders involved have not been sufficiently addressed. Regional (or local) authorities have a responsibility to promote prosperity for stakeholders in their administrative region, within the constraints of national policy; conversely companies can have financial imperatives associated with stakeholders who may be globally distributed. Evidence of these conflicting priorities, the various positions stakeholder take, and their expectations of each other can be seen in the language choices regional actors make in their public-facing policy and report documents. The aim of the paper is to consider the challenges for creating a regional-scale CE that might arise from the differing priorities and values of companies and public agencies relating to specific places. It uses discourse analysis (including critical approaches) to examine how policy and business documents represent the stakeholders of the CE, their place in it, their priorities, and, importantly, the relationship between CE actors, focusing on the case of North Humberside on the North East coast of England. The plans set out in these reports are designed for external stakeholders and allow us to gain an insight into company and policy thinking in relation to CE developments in the coming years, including how they view each other's roles. Findings indicate a shared motivation across scales and sectors for the CE as a means towards sustainable growth within which business plays a central role. However, there is a critical double disjuncture between different visions for implementation. First, between policy scales, a regional-scale CE is prioritised by regional policymakers, who have an interest in economic advantage being tied to a specific place and call for national scale support for their actions. Second, between regional policymakers and business, companies focus on their own internal operations and potential supply chain collaborations, with little attention given to the regional scale. This can be seen in the way organisations represent the actors of a nascent CE differently. In addition, a hegemonic business-focused growth discourse excludes other visions of the CE; the public are relegated to a passive role primarily as consumers and recipients of under-specified "opportunities" of wealth creation. CE theorisations need to incorporate and address these critical perspectives in order to support the development of strategies to overcome them.

Brownfield sites promote biodiversity at a landscape scale.

Repurposing of brownfield sites is often promoted, because it is perceived that protecting the "green belt" limits damage to biodiversity; yet brownfield sites provide scarce habitats with limited disturbance, so conversely are also perceived to be ecologically valuable. Combining data from three national-scale UK biological monitoring schemes with location data on historical landfill sites, we show that species richness is positively associated with both the presence and increasing area of ex-landfill sites for birds, plants and several insect taxa. Assemblage rarity of birds is also positively associated with presence of ex-landfill sites. Species richness associated with ex-landfill sites declined over time for birds and insects but increased over time for plants. These findings suggest that development of brownfield sites may have unintended negative consequences for biodiversity, and imply that to minimise loss of biodiversity, brownfield site repurposing could be targeted towards smaller sites, or sites in areas with a high density of other brownfield sites.
