A multi-criteria analysis of building level graywater reuse for personal hygiene – new article co-authored by Timos Karpouzoglou

Timos Karpouzoglou has been with the Division since 2018, and is working closely with the KTH WaterCentre, where he previously was a research coordinator. His current research is focused on urban water infrastructure and is informed by social sciences and the humanities. In a new article, together with Jörgen Wallin (KTH) and Jesper Knutsson (Chalmers), Timos investigates how water demand globally exceeds over available water supply, and takes a closer look at the reuse of bathroom graywater for shower and bathroom sink hot water. The investigation focuses on water and energy savings, water treatment, economic benefit and investigates the main actors and institutions that are involved. “A multi-criteria analysis of building level graywater reuse for personal hygiene” was published in the 2021 December issue of Resources, Conservation & Recycling Advances.

Abstract

Globally an increasing number of people are facing water scarcity. To address the challenge, measures to reduce water demand are investigated in the world. In the present paper, a novel approach to reuse bathroom graywater for shower and bathroom sink hot water is investigated. The investigation focuses on water and energy savings, water treatment, economic benefit and investigates the main actors and institutions that are involved.

The main results are that there is significant potential for water and energy savings with a positive economic benefit. Water savings of domestic hot water up to 91 % and energy savings up to 55 % were observed. The investigated treatment plant produces recycled graywater with a quality close to drinking water standards.

The investigation also presents that the reason for the positive economic benefit will depend on the utility tariffs. Therefore, two locations with different utility rate structures were investigated, Gothenburg, Sweden and Settle, USA. In Gothenburg, the utility cost for energy was the driver of economic benefit and in Seattle it was the water and wastewater cost that was the driver. The return of investment for the system and installation was shown to be 3.7 years in Gothenburg and 2.4 years in Seattle.

Abstract

Much research on the societal consequences of climate change has focused on inaction, seeking to explain why societies and individuals do not change according to experts’ recommendations. In this qualitative study, we instead consider people who have changed their behaviour for the sake of the climate: They have stopped travelling by air. We first asked them to elaborate their rationales for the behaviour change. Then, using topos theory to find thought structures, we analysed their 673 open-text answers. Several themes emerged, which together can be regarded as a process of change. Increased knowledge, primarily narrated as a process by which latent knowledge was transformed into insight, through experience or emotional distress, was important. Contrary to certain claims in the literature, fear stimulated change of behaviour for many in this group. Climate change was framed as a moral issue, requiring acts of conscience. Children were invoked as educators and moral guides. Role models and a supportive social context played an important part. Alternatives to flying were brought forward as a motive to refrain from flying. Only a few mentioned shame as momentous. Instead, stopping travelling by air invoked a feeling of agency and responsibility, and could also result in a positive sensation.

Lize-Marié van der Watt and Kati Lindström on Tourism and Heritage in Antarctica

Polar Geography has just released an article from the Creating Cultural Heritage in Antarctica Project (CHAQ) with both Kati Lindström and Lize-Marié van der Watt, the project’s PI, as co-authors. The article “Tourism and heritage in Antarctica: exploring cultural, natural and subliminal experiences” explores the inseparability of natural and cultural features in the tourist appreciation of heritage in Antarctica.

Abstract

The guidelines on heritage management adopted by the 2018 Antarctic Treaty Consultative Meeting provide the most recent iteration for an Antarctic tourism sector which had, prior to the COVID-19 pandemic, been projected to increase further with various risks and potential impacts requiring careful management. In this paper the role of cultural heritage for tourism prior to the COVID-19 pandemic is examined through three empirical perspectives. First, how the Antarctic cultural heritage is represented through the designation of Historic Sites and Monuments and Site Guidelines for Visitors; then how this is presented through tourism operators’ websites; and, finally, how it is experienced by visitors as narrated in open-source social media information. Each dataset suggests that, while cultural heritage is an important component of an increasingly commodified tourist offering, it is only part of an assemblage of elements which combine to create a subliminal and largely intangible Antarctic experience. In particular, a polarization of the heritage experience between cultural and natural does not appear productive. The paper proposes a more nuanced understanding of heritage tourism in Antarctica which accommodates the notion of a hybrid experience that integrates cultural heritage, the history and stories this heritage represents, and the natural environmental setting.

Our New Post-Doc in Energy History: Marta Musso Investigating Resource Exploitation and Possibilities for Digital Archives

Covid-19 profoundly changes the way we work. What luckily has not changed, is that new people join us at the division. Marta has recently taken up the position of a post-doc, while we are mostly working from home. Thus we asked her the following questions to introduce Marta’s work, show potential for collaboration and to get to know her a little bit better.

A picture of Marta Musso, smiling warmly and friendly, open curly brown hair, glasses

Could you please tell us about yourself and the fields you are working on?

My name is Marta Musso and I am the new post-doc in energy history at the department, working together with Per Högselius. My research follows two main strands: the first one is linked to energy policy history, and it focusses on the international economic policy of resource exploitation, and the relations between state and enterprises in negotiations for resource exploitation in the post-colonial years. The second strand of research refers to the development of digital archives, and the usage of digital-born documents on behalf of historians. I am involved in preservation projects to allow historians to make the best out of digitisation and digital technologies, such as Archives Portal Europe (www.archivesportaleurope.net). At the same time, I am an advocate of digital preservation, particularly for what concerns energy archives. Currently I am the president of Eogan, the network of energy archives.

What do you work on right now? Do you feel an impact by the current pandemic on your work?

My current research project at KTH is an extension of my PhD, which focussed on the development of the Algerian oil industry and on the nationalisation of oil resources in the post-colonial years. I am now looking at the claims of the G-77 and OPEC countries in particular with regards to the international commodity market in the years leading to and following the 1973 oil crisis. Luckily so far I have found a lot of material online (thumbs up to the UN archives which have a very good digitisation strategy!), and I have much material from my PhD years that I did not get to properly study (particular from the OPEC archives). However, I would like to also visit the OECD archives in Paris and not only are they closed, but on their website they state clearly that they do not do digitisation on demand. Hopefully the situation will change between now and Autumn 2021. Other than that, it is bad that I cannot get to meet my new colleagues and get a better feeling of the spirit of the department; on the other hand, there are a lot of interesting things happening online and I don’t feel like I am missing out. As a matter of fact, having a toddler in the house, some things are easier to do online than in person, so I also appreciate the good side of this difficult situation.

What do you aim for in the near future in terms of research, projects, or public outreach?

I hope to have a book manuscript by end of 2021, and 2/3 papers out in the meantime. I also really like to engage in public history projects, and I would like to be more involved in making documentaries or to communicate my research in other ways than academic papers – but it is difficult to find the time and the opportunities! I also hope that my research could be of interest to current energy policies, particularly with regards to international coordination in the fight against climate change. One of the aims of my current research is to show how many lost opportunities there were in the 1970s to develop a more balance global economy

In the very near future, I am presenting a volume I have recently co-edited, which is being published by the Journal of Energy History as open access, on the 11th December, at 2pm. (Registration here)

Thank you Marta. It is great to have you and your expertise with us!

Beyond Nonpartisan Discourses: Radical Knowledge for Extreme Times
by Marco Armiero

The majority of scientists agree on climate change and on the most daunting environmental problems humans are facing today. Moved by a commendable desire to contribute to the solution of these problems, several scientists have decided to speak up, telling the scientific truth about climate change to decision-makers and the public. Although appreciating the commitment to intervene in the public arena, I discuss some limits of these interventions. I argue that stating the reality of climate change does not prescribe any specific solution and sometimes it seems faint in distributing responsibilities. I ask whether unveiling/knowing the truth can be enough to foster radical transformations. Can knowledge move people towards transformative actions if power relationships do not change?Various environmental justice controversies prove that even when science is certain—and this is rarely the case in that kind of controversies—knowing might be not enough in the face of power structures preventing free choices and radical changes. In the end of my article, I state that it is fair to recognize that scientists have done their parts, and it is now up to social movements to foster the radical changes in power relationships that are needed for transforming societies.

A Sea Change in the Environmental Humanities
by Cecilia Åsberg

As we are living through a transformative response to a viral pandemic, this think piece suggests a reimagining of the environmental humanities in the open-ended inventories of feminist posthumanities and the low trophic registers of the oceanic. Sea farming of low trophic species such as seaweeds and bivalves is still underexplored option for the mitigation of climate change and diminishing species diversity in the warming oceans of the world. The affordances of low trophic mariculture for coastal life and for contributing to society’s transition into climate aware practices of eating, socializing and thinking is here considered, and showcased as an example of the practical uses of feminist environmental posthumanities.

Keywords: feminist environmental humanities, feminist posthumanities, oceanic studies, low trophic theory

New Article: Claiming Value in a Heterogeneous Solid Waste Configuration in Kampala

Division and EHL researcher Henrik Ernstson, together with Mary Lawhon, University of Edinburgh and Hakimu Sseviiri, Shuaib Lwasa and Revocatus Twinomuhangib from Makerere University (Urban Action Lab) are published in a forthcoming issue of the scientific journal Urban Geography. In the peer review article “Claiming value in a heterogeneous solid waste configuration in Kampala” they examine recycling in Kampala, the city’s complex waste systems and why little waste moves through it.

Abstract 

Kampala has a complex set of regulations describing actors, rules and procedures for collection and transportation of waste, and requires waste to be disposed of at the landfill. Yet little of the city’s waste moves through this “formal system”. Building on wider scholarship on urban infrastructure and calls to theorize from southern cities, we examine recycling in Kampala as a heterogeneous infrastructure configuration. Kampala’s lively recycling sector is socially and materially diverse: it is comprised of entrepreneurs, publicprivate partnerships and non-governmental organizations, as well as a range of materials with different properties and value. We articulate how actors assert claims, obtain permissions, build and maintain relationships as they rework flows away from the landfill. We argue that recognizing sociomaterial heterogeneity throughout the waste configuration enables a clearer analysis of contested processes of claiming value from waste. We also demonstrate how these efforts have pressured the state to reconsider the merits of the modern infrastructure ideal as a model for what (good) infrastructure is and ought to be. Various actors assert more heterogeneous alternatives, raising the possibility of alternative modes of infrastructure which might generate better incomes and improve service provision.

This article is a part of the Heterogenous Infrastructure Configurations in Uganda (HICCUP) project, funded by the Swedish Research Council.

Henrik is a long time research fellow of the Environmental Humanities Laboratory and the Division. He is a political ecologist, lecturer at the University of Manchester, world wide resident, honorary associate professor of the University of Cape Town, a postcolonial urbanist and a filmmaker to mention only a few things on a long list of engagements.
