Innovating thermal treatment of municipal solid waste (MSW): Socio-technical change linking expectations and representations

This paper combines two theoretical perspectives: future technological expectations mobilising resources; and social representations assimilating new ideas through anchoring onto familiar frames of reference. The combination is applied to the controversial case of thermal-treatment options for municipal solid waste (MSW), especially via gasification technology. Stakeholders’ social representations set criteria for technological expectations and their demonstration requirements, whose fulfilment in turn has helped gasification to gain more favourable representations. Through a differential ‘anchoring’, gasification is represented as matching incineration’s positive features while avoiding its negative ones. Despite their limitations, current two-stage combustion gasifiers are promoted as a crucial transition towards a truly ‘advanced’ form producing a clean syngas; R&D investment reinforces expectations for advancing the technology. Such linkages between technological expectations and social representations may have broader relevance to socio-technical change, especially where public controversy arises over the wider systemic role of an innovation trajectory

Linking the multi-level perspective with social representations theory: Gasifiers as a niche innovation reinforcing the energy-from-waste (EfW) regime

The multi-level perspective (MLP) theorises technological change as a process of niche innovations competing with incumbent socio-technical regimes. As a mid-range theoretical framework, the MLP invites complementary, more detailed theorisation of salient issues, especially the roles of socio-political agency in changing regime rules around technological competition. Taking a socio-cognitive perspective, this paper links the MLP with social representations theory, to show how a new technology is diversely anchored in a familiar one for different agendas. The case study is a specific niche innovation – thermal treatments of municipal solid waste (MSW) within the UK's wider regime of energy-from-waste (EfW). Through landscape-level changes, controversy over incinerators has destabilised the EfW regime's rules. This instability has opened up opportunities for gasifiers as a niche innovation, yet gasifiers have also become an extra focus for conflict over incinerators' wider role in the waste hierarchy. Agents compare thermal-treatment options for MSW according to various criteria which have unstable, changing rules. These express different socio-cognitive frameworks, analysed here as diverse social representations of novelty. The case study offers an insiders' perspective on endogenous enactment, i.e. the conflicting roles of socio-political agency in shaping transition pathways

Grassroots social innovation and the mobilisation of values in collaborative consumption: a conceptual model

There is growing interest in the potential of grassroots innovations to play a role in the transition to sustainable production and consumption systems. However, the role of values has been little considered in relation to the development and diffusion of grassroots innovations. We develop a conceptual model of how citizens’ values are mobilised by grassroots innovations, drawing on the value theory of Schwartz et al. (2012) and the theory of collective enactment of values of Chen et al. (2013). Using the results of a large scale survey of free reuse groups (e.g. Freecycle and Freegle), which enable collaborative forms of consumption, we apply the conceptual model to explore how participants’ values are mobilised and expressed. We show that while the majority of free reuse group participants do hold significantly stronger self-transcendence (i.e. pro-social) values than the wider UK population, they also hold other values in common with that population and a minority actually place less emphasis on self-transcendence values. We conclude that diffusion of this particular grassroots innovation is unlikely to be simply value limited and that structural features may be more significant

Afghanistan's energy sociotechnical imaginaries:Alternative visions in a conflict zone

Imaginaries are understood to be both discursive and cognitive constructs that shape behaviour, policies, and institutions – but how do longstanding imaginaries evolve in new circumstances, and how do they interact with existing power structures in changed circumstances? Drawing on conceptions of discursive power, this paper investigates the interplay of power with both new and old imaginaries in the case of Afghanistan, specifically regarding alternative energy futures. Employing an interpretive approach, we draw on document analysis and semi-structured interviews with elite stakeholders and policy observers, to provide an account of the relations between alternative energy futures imaginaries and political power. We demonstrate, how certain discursive practices are made possible, authorised and articulated through imaginative geographies. Critically, the government-advocated imaginary of Afghanistan as an energy corridor and hence an energy importer both represents the views of several powerful interests and concurs with the long-held idea of Afghanistan as a buffer state. In this way, political path dependencies are reinforced through a supportive imaginary, just as the dominant imaginary is itself reinforced by the main stakeholders. While in line with our interpretive epistemology we do not make claims for the specific configuration of imaginaries being generalisable elsewhere, we do find the general theoretical approach useful for understanding discursive aspects of conflict zone politics, particularly vis-à-vis energy system trajectories

Narratives of change: Strategies for inclusivity in shaping socio-technical future visions

Narratives of change are increasingly becoming the focus in the context of sustainability transition, and one reason for this is the growing awareness of the impact of language on our environment. Drawing on an analysis of narratives of change of the Swedish strategic innovation program Viable Cities, in our article we illustrate how intermediary organizations seeking to facilitate sustainable futures use narratives to develop their strategies for inclusivity, and we discuss the value of narrative analysis to understand such mediation. In so doing, we draw on a narrative approach from literary studies and show the added value of analysis of textual presentation techniques for sustainability transitions research. As interpretations of discourse, narratives shape social communities and not only tell us about change, but also witness, and are intended to drive, specific changes. Our analysis of the presentation techniques of the narrative of Viable Cities reveals the ways in which the narrative seeks to achieve the goal of inclusion, to help drive change towards the goals of sustainability. This is done through the plurality of the storylines and the narration; while the plurality of perspectives is maintained through the essayistic character of the texts, as well as through stretching the time of the narrative

Imaginaries on ice:Sociotechnical futures of data centre development in Norway and Iceland

In 2018, Norway promoted itself as a ‘Datacentre Nation’. In terms of low cost, renewably generated sources of electricity and low ambient temperatures, Nordic countries and the data centre sector are potentially mutual beneficiaries – yet, there are also negative impacts associated with the necessary electric power production. With this as a starting point, for Norway and Iceland, we explore how data centre proponents promulgate similar techno-environmental imaginaries, but achieve differing degrees of stabilisation. To this end, we use three sources of imaginaries relating to data centre development in Iceland and Norway: those implicit in promotional imagery originating within the countries concerned; those implicit in international newspapers, as indicative of external perceptions; and those implicit in focus groups with the Norwegian and Icelandic public. We show how data centre advocates deploy visual imagery to create a promotional techno-environmental imaginary that marries nature with the digital in a symbiotic form, and we observe that this is largely consistent with the more mundane international imaginary of Norwegian data centres. For Iceland, however, the external imaginary is dominated by associations of excess energy consumption by bitcoin mining. For the publics questioned, there are multiple imaginaries of data centres, with significant notes of moral and other forms of scepticism. Looking ahead, we suggest that for long-term stabilisation of positive data centre imaginaries, conducive to investment, the capacity of Iceland and Norway to equitably supply sufficient renewable power will need to be addressed as a matter of urgency.</p

What is needed for citizen-centered urban energy transitions : Insights on attitudes towards decentralized energy storage

This paper aims to fill a research gap in the area of consumer-citizen attitudes to business models for decentralized energy storage, at the level of households and buildings. The study focuses on the interaction of such attitudes and their underlying motivation factors with socio-cultural, contextual factors. Self-determination theory (SDT) is used as a theoretical framework, to connect interpersonal and contextual factors, addressing the question of how contexts influence the motivation to support energy storage. Drawing on SDT, this study examines the role of autarky (independence from the energy system), autonomy (control over energy management) and relatedness (degree of sharing required) in this regard, embedded and interpreted in the socio-cultural local context of two demonstration sites in Sweden and Portugal. A mixed method approach is used. Quantitative survey data provides information on local social and cultural dimensions, followed by stakeholder consultation workshops that elicit participants’ views on different models of decentralized energy storage. The findings raise questions of how to improve autarky and autonomy for prosumers, while keeping the need for time investment low and provide flexibility regarding the required degree of interaction between prosumers. Implications for business models and policy support for citizen-centered sustainable urban energy systems are derived
