Mind the gap(s)! Ressursmegling for å kutte det norske matsvinnet

Magma forskning og viten, 25(5), s. 95- 103.

Hvert år kastes rundt en tredjedel av all spiselig mat i Norge. En stor andel av svinnet oppstår før maten når butikkhyllene, hovedsakelig fordi den har «feil» utseende, form eller farge målt mot etablerte standarder. Dette utgjør et betydelig klimagassutslipp, økt press på landareal og stadig voksende avfallsmengder, og det representerer et verditap for den norske økonomien på over 20 milliarder kroner. I produsentleddet finnes det per i dag ikke god statistikk for omfanget av svinn. Fra et faglig perspektiv representerer dette skjulte svinnet et kunnskapsgap for fremgang innen den sirkulære økonomien. Fra et forretningsperspektiv representerer gapet mellom svinn og ressursutnyttelse store muligheter for forretningsmodellinnovasjon og nye verdikonfigurasjoner. Det er store verdier å hente på å utnytte ressursene som kasseres i dagens lineære økonomi. Denne artikkelen peker på ressursmegling via digitale plattformer som en forretningsmodell som kan oppnå betydelige kutt i det norske matsvinnet ved å fungere som et bindeledd mellom avfallsstrømmer og nye bruksområder, ved hjelp av digitale plattformer. Vi benytter resultater fra en forbrukerundersøkelse gjennomført blant norske husstander på temaet «matsvinn og ikke-standard matvarer», og hevder på grunnlag av disse resultatene at det ligger et betydelig verdipotensial i å tette informasjons- og koordineringsgapene som i dag preger matbransjen. Vi forsøker å belyse norske forbrukeres holdninger til «ukurante varer» og diskuterer faktorer for å lykkes med ressursmegling ikke bare innen matbransjen, men også den norske økonomien mer generelt.

Willingness to Pay for Crowdfunding Local Agricultural Climate Solutions

Sustainability, 13(16) Doi: 10.3390/su13169227

The recent rise in climate concern among citizens worldwide is coinciding with a rising interest in agricultural climate solutions. The future scaling-up of these solutions, however, requires more knowledge about the mitigation potential, costs and financing options, including crowdfunding (CF). Our objective is to explore the driving factors behind the public’s willingness to pay for crowdfunded climate mitigation projects at the farm level. In this study, four mitigation options from the perspective of farmers were identified: solar panels on the barn roof, biogas from animal manure, drag hoses for improved manure dispersal, and the addition of biochar to soils. The study investigates the optimal characteristics of crowdfunding campaigns to finance such mitigation measures. The most influential factors on the respondents’ WTP is neither climate concern nor proximity, but instead the knowledge regarding CF, combined with how comprehensible and salient the suggested measure is. The main implications are that future projects that aim to achieve broad participation in CF campaigns need to communicate well, to improve both public knowledge of the funding mechanism (CF) itself and the comprehensibility and salience of the agricultural measure.

‘On the Road to Circular Aggregates’

[Academic lecture]. IMP Conference 2024.

In this paper we aim to investigate how a group of public agencies and projects sought to develop market agencement through the collaborative governance of market devices for re-framing residual materials in the context of a circular economy for construction aggregates. Our analysis of two cases of market agencement for residual construction aggregates, we identify the introduction, elaboration, and enforcement of new market devices as a key mechanism for re-categorizing residual aggregates as calculable and tradable in the marketplace. This process involved combining and overlaying existing (and historically predominant) market devices for ensuring waste and pollution control, oriented around centralized indicators for allocating ‘pollution allowances’ and limits on ‘contaminated content’, with novel waste re-categorization devices, such as material classification, certification and declaration schemes demonstrating the productive properties and functionality of residual materials. Through prolonged fieldwork, we shadowed key market actors in their endeavour to mobilize commercial and public support for a new market for residual aggregates materials. Our analysis of stakeholder claims and interactions, throughout the two case contexts, unearths the various calculative frames that were introduced to make salient the wastefulness of extant (linear) practices, while simultaneously allowing for (re)evaluating treatment, sorting, and classification activities as valuable and marketable. They achieved this, we argue, through the ‘peripheral vision’ of new calculative devices (Callon & Muniesa, 2005) that downgraded extant practices such as landfilling old, and excavating new, construction aggregates as wasteful and costly, while convincing public authorities of the benefits of facilitating the market exchange of residual aggregates. This, we argue, involves the mutually enforcing processes of regulate-ing and market-ing a set of end-of-waste criteria, which ultimately allowed for the economic and circular organizing of a previously non-economic and un-marketable residual material.
