Rapid technological innovations, including the emergence of the Internet of Things (IoT), introduce a range of uncertainties, opportunities, and risks. While it is not possible to accurately foresee IoT's myriad ramifications, futures and foresight methodologies allow for the exploration of plausible futures and their desirability. Drawing on the futures and foresight literature, the current paper employs a standardised expert elicitation approach to study emerging risk patterns in descriptions of IoT risk scenarios. We surveyed 19 IoT experts between January and February 2018 using an online questionnaire. The submitted scenarios provided expert's perception of evolving IoT risk trajectories and were evaluated using thematic analysis, a method used to identify and report patterns within data. Four common themes were extracted: physical safety; crime and exploitation; loss of control; and social norms and structures. These themes provide suitable analytical tools to contextualise emerging risks and help detecting gaps about security and privacy challenges in the IoT.

Blockchain technology is emerging as a plausible disruptor of waste management practices that influence the governance of plastics. The interest among the waste management community in the potential and fundamental changes to complex resource management associated with blockchain adoption parallels recent research in other sectors, such as finance, health, public administration, etc. During any comparable period characterized by a step-change in positive coverage of an early-stage technology, it can be challenging for actors to access a grounded, evidence-based oversight of the current state of practice and make informed decisions about whether or how to adopt blockchain technology. The current absence of such a systematic overview of recent experiences with blockchain initiatives disrupting waste practices not only limits the visibility of these experimental efforts, but also limits the learning that can be shared across waste plastics researcher and practitioner communities. This paper contributes with a current overview of blockchain technology adoption in the waste management sector, giving particular attention to implications for the governance of plastics. Our study draws on both primary interview data and secondary documentation data to map the landscape of current blockchain initiatives in the global waste sector. We identify four areas of blockchain use that are beginning to change waste management practices (payment, recycling and reuse rewards, monitoring and tracking of waste, and smart contracts). We conclude by outlining five areas of significant blockchain uses, implications, and influences of relevance to the development of circular plastic waste governance in both research and practice.

The global waste and resource crises necessitate and give great impetus for better and more sustainable management of waste. Increasingly, resource and waste streams that once were sent to landfill or incinerated are now reused, recycled, or recovered. Yet, while many laws and policies have been adopted for this very purpose, a number of recurrent challenges persist across interventions seeking to further facilitate the necessary, widespread transitions to sustainable waste management. This perspective article explores the suitability of blockchain technology in overcoming these challenges. In particular, we discuss the opportunities and challenges for blockchain in (1) offering clarity in property rights of products and wastes, (2) supporting law and policy goals by incentivizing sustainable waste management, and (3) maintaining anonymity and privacy for institutions and individuals.

The literature on blockchain technology and circular economy is at a nascent stage, with only initial limited and superficial recognition of the possible role blockchain may have in supporting circular economy laws and policies. This paper contributes to this emerging area by exploring the regulatory opportunities and challenges for adoption of blockchain for circular waste management. In particular, through a mixed methods approach combining empirical and doctrinal research, this paper presents initial findings on: (1) the current role of blockchain within the legal landscape on circular economies;(2) the regulatory barriers of blockchain application to circular economies; and (3) opportunities of blockchain in supporting regulatory mechanisms promoting circularity.
