This article provides a nano (hyperlocal) view of climate change mitigation by viewing regenerative organizing through the eyes (as well as bodies and senses, etc.) of the households engaged in community-based energy projects. By showing what humans make up for in the largely absent relationship between nature and technology in these projects, we envision an incremental extension of the literature on community-based energy. The radically different contribution we aim to make is a tripartite imbrication that brings in natural agency alongside the human and the technical but specifies precisely how nano (smaller than micro) embodied practices afford mis- and realignments. https://doi.org/10.1177/1086026619886841 LinkedIn: https://www.linkedin.com/in/helenkopnina/

The relevance of citizen participation in regeneration projects, particularly in shrinking cities, is widely acknowledged, and this topic has received a great deal of policy and academic attention. Although the many advantages of citizen participation in regeneration projects have been identified, its current forms have also received considerable criticism. In short, this criticism boils down to the conclusion that the ideal of citizen participation is not put into practice. This paper considers why this is the case, asking whether current participatory practices enable citizens to exercise influence as political actors in urban regeneration projects. In this paper, we examine this question based on Mouffe’s conception of the political, coupled with findings from our empirical research conducted in Heerlen North, The Netherlands. We conducted qualitative research on urban regeneration in the shrinking old industrial city of Heerlen. The findings reveal two distinct perspectives on citizen participation. Professionals see the existing context of citizen participation as a reasonable and practical but, in some respects, insufficient practice. Citizens’ views on participation are organized around feelings of anger, shame, and fear and are grounded in experiences of a lack of recognition. These experiences limit citizens’ abilities to exert true influence on regeneration projects. We conclude that efforts to regenerate shrinking cities should strive to recognize these experiences so as to create conditions that generate respect and esteem and, as such, enable urban social justice.

Paper sludge contains papermaking mineral additives and fibers, which could be reused or recycled, thus enhancing the circularity. One of the promising technologies is the fast pyrolysis of paper sludge, which is capable of recovering > 99 wt.% of the fine minerals in the paper sludge and also affording a bio-liquid. The fine minerals (e.g., ‘circular’ CaCO3) can be reused as filler in consumer products thereby reducing the required primary resources. However, the bio-liquid has a lower quality compared to fossil fuels, and only a limited application, e.g., for heat generation, has been applied. This could be significantly improved by catalytic upgrading of the fast pyrolysis vapor, known as an ex-situ catalytic pyrolysis approach. We have recently found that a high-quality bio-oil (mainly ‘bio-based’ paraffins and low-molecular-weight aromatics, carbon yield of 21%, and HHV of 41.1 MJ kg-1) was produced (Chem. Eng. J., 420 (2021), 129714). Nevertheless, catalyst deactivation occurred after a few hours’ of reaction. As such, catalyst stability and regenerability are of research interest and also of high relevance for industrial implementation. This project aims to study the potential of the add-on catalytic upgrading step to the industrial fast pyrolysis of paper sludge process. One important performance metric for sustainable catalysis in the industry is the level of catalyst consumption (kgcat tprod-1) for catalytic pyrolysis of paper sludge. Another important research topic is to establish the correlation between yield and selectivity of the bio-chemicals and the catalyst characteristics. For this, different types of catalysts (e.g., FCC-type E-Cat) will be tested and several reaction-regeneration cycles will be performed. These studies will determine under which conditions catalytic fast pyrolysis of paper sludge is technically and economically viable.
Artificial grass is much more durable and easily maintained than natural grass and therefore finds use in a wide range of applications. The artificial grass system consists of various components which are currently predominantly made of non-biodegradable plastics derived from fossil fuels. Consequently, it has a large environmental impact and is a significant contributor to the world’s (micro)plastic problem. Simultaneously, the world is suffering from a textile waste problem. In the EU only, 12.6 million tons of textile waste is produced annually. Most of this post-consumer textile waste ends up in landfills or incinerators. Striving for a circular economy, new regulations like the Extended Producer Responsibility (EPR) define goals for the collection and recycling of this textile waste. A dominant textile-waste stream is cotton, which consists of the biodegradable biopolymer cellulose. Cotton can be eco-friendly chemically recycled into regenerated cellulose fibres using the lyocell wet-spin process. The ReCeWTAG proposal will explore regenerating cellulose pulp from textile waste into natural artificial grass-like fibres. Currently cellulosic fibres do not have the same properties as synthetic fibres. This applied project will explore how regenerated cellulose grass fibres can be produced with the properties required by varying parameters on Saxion’s recently installed wet-spinning line. SaXcell BV will supply cellulose pulp generated from various cotton-containing textile waste-streams. TenCate Thiolon BV will advise on the required properties. bAwear will assess the environmental impact benefits. The aim is to follow-up this project to replace all synthetic components in artificial grass with cellulose creating a circular system as well as expanding the concept to other technical textiles. It will also assess waste streams like agricultural residues for cellulose regeneration, supporting the circular economy by reducing microplastics, waste and environmental impact.
"Regenerative Renaissance" (RR) embarks on an innovative journey to reshape the Fashion and Textile Industry's (FTI) societal and environmental influence. This project, led by University of Groningen (UG) in partnership with fashion designer Joline Jolink (JJ) and local farm Boerderij Gagel: Lente Land (LL) aims to transform Joline’s business into a leading regenerative small-medium enterprise (SME), establishing new norms for social and net positive circularity in the Dutch FTI. It probes how the FTI can progress from sustainability (net zero) to regeneration (net positive), focusing on fostering a symbiotic bond between fashion/textile production and land regeneration, connecting textiles and people with the land. This vision transcends traditional sustainability, seeking to actively enhance environmental restoration, biodiversity and creating multiple values. It entails a transformation of the fashion business model (BM), embedding regenerative practices into all aspects of running a fashion business and strengthening the ties between humans and nature. RR strives to reduce the fashion industry's environmental impact while enriching ecosystems and communities. The project involves collaborating with local communities and stakeholders to co-create initiatives like community farming, educational workshops, creating alternative products and a clothing line that reflects regeneration principles in its making and storytelling. The ultimate goal is to develop a replicable regenerative BM for the FTI, redefining the interaction between fashion, society, and the environment, and prompting a balanced shift towards a sustainable, ecologically harmonious future.
