Operationalizing Industrial Ecology in the Waste Sector : Roles and tactics for circular value innovation
- 2017
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The take-make-waste approach to resource management in human production and consumption systems is contributing to a variety of environmental and social problems worldwide. Additionally, as the world’s population and affluence increase, so do the negative impacts of poor resource management. Lifting the waste management (WM) sector into a new phase of development, which takes its lead from the ideals of Industrial Ecology and circular economy, is seen by many scholars and practitioners as one potential to assist in alleviating these impacts. While there are many studies on how more efficient inter-organizational resource management is (or could be) constructed, there are relatively few business development studies which have explored novel approaches (from roles to tactics) that WM organizations might operationalize toward more efficient resource management.The aim of this thesis is to contribute to the development of knowledge and understanding of how the waste management sector can operationalize more effective and efficient resource management. In approaching this aim, two research questions guided the exploration of: 1) novel roles for WM and 2) support tactics for such roles. Grounded in the broader context of Industrial Ecology (IE) and Business Development, five studies were performed. Two studies, focused on the novel roles of inter-organizational resource management and high value secondary resource extraction, were performed through literature review and interviews, and market driver analysis respectively. In exploring support tactics, two design and proof of concept studies were carried out to investigate data analysis tools for inter-organizational resource management, and one long-term action research engagement project was coordinated to study hands-on inter-organizational collaboration tactics.The studies highlighted that the Swedish WM sector holds some key capacities for operationalizing (and in some cases, is already developing) the novel resource management roles identified: industrial symbiosis facilitator, eco-industrial park manager, holistic facility management, and high value resource extractor. However, depending on the portfolio of services to be performed in such roles, several capacities may need to be developed or strengthened. Main opportunities seen for these roles were – staying ahead of market developments, and aligning activities with organizational goals. The main general risk related to these roles was insufficient returns on investment. Looking forward, the main enablers identified were policy leadership for more balanced market mechanisms, increasing use of external knowledge, developing long term partnerships, lobbying, stockpiling resources, and carefully crafting new business models.The tools developed for strategically applying external information toward the identification of opportunities within new roles showed tactical potential. However, their implementation in broader development processes has yet to be fully validated. The hands-on exploration of change oriented collaboration, highlighted collective system framing and goal setting and face-to-face interaction as key activities for inter-organizational approaches within roles such as industrial symbiosis facilitator.Throughout the studies, several novel roles were investigated. Each of these roles will need to be individually evaluated by directing bodies of WM organizations, and evaluated from the organization’s vision and strategy. If certain roles are chosen to be explored in more detail, they will need to be developed within full business models - addressing issues such as income structure, internal processes and capacities to be developed, and key customers. Through applying IE and business development concepts and findings, WM organizations have possibilities to translate ambitious visions into novel offerings.

Sharing Resources for Greener Logistics
- 2024
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Freight transportation, a significant contributor to the environmental impact of logistics, is projected to grow, thereby increasing its environmental footprint. With many actors contributing to the greening of logistics, their roles, and responsibilities for the greening of logistics differs. One mean for progressing the greening of logistics, is to share resources between actors needed for implementing different green logistics practices. Resource sharing among these actors will be a key strategy for advancing the greening of logistics.The purpose of this thesis is to increase the understanding how resources can be shared between actors to facilitate the implementation of green logistics practices. It focuses on the different green logistics practices that can be implemented to green logistics through a resource perspective, where resources and actors that controls resources and implements green logistics practices are the subject of analysis. Through the application of resource dependency theory, this thesis sets out to understand why actors need to share resources with other actors, and how they can manage their dependency onto resources controlled by other actors.The findings of suggest that there are different resources needed for green logistics: knowledge, technical resources, financial resources, time, employees, and IT-systems. The actors that control these resources or that implements green logistics practices are: logistics service providers, shippers, customers, technology providers, and governmental authorities. Through the lens of resource dependence, it is suggested how the dependencies can be managed through resources sharing between different actors. These ways of sharing resources are characterized by three parameters: duration (short-term vs long-term), directness (direct vs indirect), and scope (resource sharing with one or multiple actors). Through a combination of these parameters, different ways of sharing resources between actors are proposed.The contributions of this thesis are primarily aimed at enriching the green logistics literature and enlightening logistics practitioners. Theoretically, it extends our understanding of interaction for greener logistics by focusing on resource sharing between different actors. By applying resource dependency theory, a deeper understanding of why and how actors can share resources to enable the greening of logistics is given. Additionally, this thesis proposes a categorizations of green logistics practices, actors, and resource. This can be used to further understand green logistics, whilst simultaneously be a tool for practitioners to understand their role in the greening of logistics.

Calcium Homeostasis in Patients with Graves' Disease
- 2016
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Patients with Graves´ Disease (GD) have a higher risk of developing more severe and prolonged hypocalcaemia after total thyroidectomy (TT) than patients who undergo surgery for benign atoxic goitre. Since TT is the most effective treatment for GD, it is crucial to identify mechanisms for postoperative hypocalcaemia. The aim of this thesis was to study the mechanisms of calcium metabolism in patients with GD.It is safe to operate on GD patients with TT. Results in Paper I showed fewer recurrences and equal complication rates compared to patients who underwent subtotal thyroidectomy (ST). The transient lowering of PTH seen in the hypocalcaemic patients was fully restored one month after surgery (Papers II and V).The calcium-sensing receptor (CaSR) is crucial for maintaining plasma calcium, and single nucleotide polymorphisms (SNPs) in the gene may alter the sensing function. Thus, we analysed SNPs in CaSR in GD patients (Paper II) and showed that they had a more left-shifted calcium-PTH set-point compared to controls, implicating higher sensitivity. This is also supported by the results in the group of postoperatively hypocalcaemic patients. They already had lower plasma calcium preoperatively (Papers II, IV and V) and lacked the T/G G/A G/C, a haplotype shown in Paper III to have a close relationship to higher p-calcium levels. Moreover, a lack of the T allele in rs1801725 was seen in the group of patients needing permanent treatment with calcium and vitamin D, i.e. > 12 months, (paper V).Patients who became hypocalcaemic (p-calcium < 2.00 mmol/L) on day one postoperatively, had lower preoperative levels of thyroid stimulating hormone (TSH) and higher levels of T3, this was also applied to the patient groups requiring temporary or permanent postoperative treatment (Papers II and V). In addition, hypocalcaemic patients treated for less than six months with anti-thyroid drugs had higher levels of bone metabolism markers CTX and P1NP than normocalcaemic patients (Paper V).In conclusion, the postoperative period of hypocalcaemia seen in patients with GD is a complex medical condition, caused by a combination of surgical trauma, different SNPs in CaSR, and high bone metabolism related to preoperative thyroid metabolism.

Ett nödvändigt drivmedel i transformationen mot ellastbilar? : En jämförelse av resursdelning mellan två tekniker
- 2024
-
Ingår i: Transportforum.
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Aktörssamverkan är central för omställning mot en grönare transportsystem, exempelvis vid omställning till eldrift. En organisation i isolering har inte allt det som krävs för en omställning till eldrift, och resurser måste istället delas mellan centrala aktörer såsom fordonstillverkare, infrastrukturhållare och logistikföretag. En aktör har tekniken medan en annan kanske har kunskapen. Beroendet kan vara av olika karaktär och dess omfattning påverkas av exempelvis hur kritisk eller vanlig resursen är. Men på vilket sätt är dessa beroenden centralt vid valet av lösning? Laddning av batterier med sladd är det koncept som vi satsar främst på inom Europa, medan byte av batterier (battery swapping) är den teknik med störst genomslag i exempelvis Kina. Vi har jämfört vilken roll resursdelning har för dessa tekniker.Studien har jämfört resultat från två forskningsprojekt finansierade av Vinnova och Energimyndigheten. Båda projekten har haft arbetspaket som berör samverkan, samtidigt som de fokuserar olika former av tekniska lösningar. Empirin kommer från en strukturerad intervjustudie med 19 svenska logistikaktörer som testat sladdladdning, djupare intervjuer och workshops med olika aktörer från akademi och näringsliv. Empiriska data har analyserats utifrån Resource dependency theory.

Logistics Service Providers Going Green : A Framework for Developing Green Service Offerings
- 2014
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Environmental impact has increasingly become a “buzzword” and an important topic. This topic has been integrated into the agenda of many companies worldwide, and this dissertation focuses on the transportation and logistics industry. Environmental concerns have gained increased attention among many logistic service providers (LSPs) due to the environmental impact from their operations, and they have been identified of having a significant role in reducing the environmental burden in the supply chain. An environmental approach of the LSPs' business has also been identified as a way to achieve competitive advantage and provide market opportunities where the development and marketing of new products and services associated with green issues are suggested as important aspects for future growth. However, considering the scarcity of research regarding this topic, a study that reveals potential aspects in the development of green service offerings can bridge the knowledge gap and provide opportunities for further research within this field. The purpose of this dissertation is therefore to develop and explain a framework for LSPs’ development of green service offerings. The purpose is addressed by first investigating LSPs' service development from a general perspective in order to, in a second stage, reach a better understanding of the implications when integrating green aspects in LSPs' service development efforts.Theoretically, this dissertation departed from service marketing literature or more specifically new service development (NSD) research. This resulted in a conceptual framework including key dimensions and aspects regarding a company’s NSD efforts and activities. From this foundation, the theoretical framework was developed further based on research regarding LSPs' service development and innovation management. Finally the framework was extended with green logistics literature as well as research regarding LSPs' green development and influences on their service offerings.Empirically, this research is mainly based on qualitative data from an in-depth case study on a large LSP active on the Swedish market. In addition, empirical data from a multiple case study and a questionnaire survey conducted for the Licentiate thesis were used in order to enrich the analysis regarding the LSPs' development of green service offerings. The analysis followed a stepwise approach where literature and empirical data were analysed.One of the main results in this dissertation is the framework for LSPs' new service development, consisting of five dimensions: NSD culture, NSD strategy, NSD process focus, IT use and expertise and NSD knowledge and skills. The NSD framework presents a holistic view of the LSPs’ NSD efforts by revealing different dimensions, their roles and relations to each other as well as the pre-requisites to take into consideration in the development of new services. Thus, the different NSD dimensions should not solely be viewed as isolated dimensions; instead, there is a need for LSPs to have a holistic view and understanding of the NSD activities’ reciprocity.Another main result concerns the adaption of the NSD framework to green service development. The results reveal some pre-requisites relevant for LSPs to consider in their efforts to develop green service offerings and are summarised in the following main dimensions:Creating green awareness in the NSD culture – encourage participation regarding green initiatives within the organisation, defining a “common picture” in order to facilitate collaboration efforts and knowledge exchange concerning green expertise. The support from top management was also identified of having an influencing impact. Defining the strategic approach of green service offerings – integrate a green concern in the overall business strategy and to define the strategic role and incentives for developing green service offerings. The results also suggest LSPs to adapt green NSD efforts to different business contexts and market possibilities to match existing resources and skills with customers’ green requirements, and to perform a segmentation of customers’ environmental work and ambitions to increase the understanding of customers’ green attitudes and requirements.Create processes and routines to facilitate spreading of green knowledge – highlights the relevance of a process focus for spreading green knowledge both from an external and internal perspective. It involves e.g. adoption of certifications, procedures for environmental calculations and documentation as well as routines to spread and integrate green knowledge among employees as well as identification of customers’ green requirements.Improve green internal knowledge and build green collaborations – provide training and education to increase the level of green awareness and knowledge among employees as well as customers and strive for collaboration efforts both internally and externally to utilise each other’s knowledge and resources towards the development of green service offerings.Increase transparency of green information both internally and externally – improve green information transparency to build both internal and external trust and increase possibilities to effectively use other actors’ knowledge and resources to develop environmental improvements in the supply chain. Integration of IT expertise and synchronisations of IT systems to facilitate and support environmental work and development of green service offerings.

Urban Consolidation Centres : On Relationships between Customer Needs and Services in City Logistics
- 2018
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Urban Consolidation Centres (UCCs) are often conceived as an enabler to alleviate negative effects associated with distribution of goods in cities, such as traffic congestion and hazardous emissions. UCCs not only have the potential to reduce these effects but also provide alternative distribution solutions by introducing new transhipment points. Despite their potential, UCCs often fail to be self-supporting and are often dependent on subsides, which is not considered to be sustainable in the long run. In response, this thesis takes its point of departure in the two business models elements value propositions and target customers. A business model is often viewed as an enabler to generate revenue and UCCs have the potential to generate revenue by offering services to their customers, and the customers pay for the services. To understand how customers can benefit from UCCs and provide arguments why they should use these, it is important to understand the relationship between customers’ needs and the services UCCs can provide. The purpose of this thesis is to identify and describe the potential relationship between needs of UCC customers and UCC services.The research in the thesis is both explorative and descriptive, where a first step is to identify customer needs, UCC services, and value propositions. The descriptive part is to describe them and it is also the foundation for understanding the relationship between customer needs and UCC services. Through the analysis and discussion, multiple customer needs are identified and described for seven customer groups and the UCC operator; all of which could be considered customers of UCCs. The thesis also adds to the UCC literature with three new identified UCC services: e-commerce with used products, advertisement, and registration in computer system. The outcome of the analysis also provides illustrations of how customer needs can be matched with UCC services. For the most studied customer group, receiver of goods, a total of 29 different matches were identified, which illustrates the possibilities but also the complexity of the relationships. To understand the relationship, three different types of gaps were also identified that have implications for future research.The main contributions to research and the UCC literature in particular are enlargement of the scope of customers and the illustration of the relationships between customer needs and UCC services. The illustrations include contributions such as identifying, mapping and describing the customer needs, UCC services, and value propositions. An important first step is to understand how customer needs and UCC services can be linked, and this thesis provides examples of how this can be achieved. Viewing every stakeholder as a potential customer opens up the opportunity to fulfil their needs and the potential to generate revenue, which in turn could close the gap in the problem of non-self-supporting UCCs. Furthermore, with self-supporting UCCs, the number of freight vehicles can be reduced and this may lead to more attractive cities with less traffic congestion and lower emissions.

Towards greener supply chains : Inclusion of environmental activities in relationships between logistics service providers and shippers
- 2014
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- It is well-recognised that companies are under pressure to take responsibility for the environmental impact of their operations. Logistics service providers (LSPs), who through their transport and logistics operations have a large negative impact on the environment, are one type of supply chain actor that is under such pressure. However, in order for LSPs to be able to lower their environmental impact sufficiently, their customers, the shippers, also need to take responsibility. This thesis takes its starting point in the relationships between LSPs and shippers and argues that in order for LSPs’ environmental activities to reach their full potential, the shippers must be included in the activities.The purpose of this thesis is to describe and explain how supply chain actors, with a specific focus on logistics service providers and shippers, can include environmental activities in their relationships with each other. This comprises identifying those environmental activities that are relevant for relationships between LSPs and shippers, as well as describing the extent to which environmental activities are included in such relationships. By means of the theoretical perspective of power between supply chain actors, the thesis also sets out to further understand how power balances between LSPs and shippers can influence the extent to which they include environmental activities in their relationships with each other. Finally, the use of the theoretical perspective of coordination aims, through the analysis of coordination mechanisms, to shed light on how environmental activities are included in LSP-shipper relationships.The research in this thesis has mainly descriptive and explanatory aims, although due to the novelty of research into LSPshipper relationships in an environmental context, the research process as such is mainly exploratory. Following an abductive approach, the insights from literature are combined with empirical data from two cases studies, a homepage scan, a survey and a study of city logistics projects. Most of the applied research methods take a dual perspective of relationships between supply chain actors and thus include both LSPs and shippers.One conclusion from the research conducted for this thesis comprises the identification of environmental activities as well as a suggestion for a classification based on the activities’ role in the business between LSPs and shippers. With a starting point in the identified activities, a comparison of a market perspective and a relationship perspective of environmental activities in LSP-shipper relationships indicates that LSPs are able to fulfil the requirements set by shippers and that shippers’ requirement thus are met. The research does, however, point to a passiveness among LSPs in their relationships with shippers, who in turn would like the LSPs to be more proactive.Further, based on an analysis of power balances in LSP-shipper relationships, it is suggested that in an LSP-shipper relationship in which the shipper has a power advantage, the shipper’s environmental ambitions for logistics sets the agenda for the environmental activities in that relationship.An analysis of coordination of environmental activities in LSP-shipper relationships indicates that the mechanisms of direct supervision, which is when one actor tells the other actor in the relationship what to do, and mutual adjustment can be chosen to be used in order to include environmental activities in LSP-shipper relationships. While direct supervision is suggested to be a coordination mechanism that is easy for shippers to apply, mutual adjustment appears to hold greater potential for the development of environmental activities.Finally, these findings in combination are suggested to have implications for the coordination of environmental activities in LSP-shipper relationships. More specifically, this thesis offers a categorisation of different types of LSP-shipper relationships and the involved actors’ environmental ambition. Depending on whether the environmental ambition of the LSP and shipper in a specific relationship is high or low appears to have implications for the possibility to work towards greener supply chains for each type of relationship.

Battery-Swapping for Heavy Duty Vehicles : A Feasibility Study on Up-Scaling in Sweden
- 2024
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Rapporten fokuserar på den kommersiella genomförbarheten av ett batteribytessystem för tunga lastbilar i Sverige. Genom att studera affärsmodeller, kompatibilitet med svenska regelverk och integration i transportverksamheten har vi utforskat hur disruptiva teknologier, ekosystemeffekter och cirkularitet skulle kunna möjliggöra en snabb introduktion och uppskalning av ett batteribytessystem. Ett särskilt fokus har legat på Kina för att analysera statusen för batteribyten och de processer som har lett till den snabba utvecklingen och uppskalningen där. I Kina krävde batteribyte en ny affärsmodell där aktörer såsom energiproducenter, batteritillverkare och maskinindustri går i spetsen för utvecklingen och spridningen av batteribyten. Batteribyte är nu den dominerande tekniken för eldrivna lastbilar i Kina.Exempel på fördelar med batteribyte som förespråkas är att det bara tar några minuter att byta batteri, minskad investering för lastbilsägare, låg påverkan på det lokala elnätet och att fordons- och batterilivscykler separeras. En simuleringsstudie om batteribyte för tunga lastbilar i hamnverksamhet visar i denna rapport på tydliga fördelar jämfört med kabelladdning. Det finns dock ett par utmaningar med att införa batteribyte i Sverige. För det första finns det inga tydliga förespråkare för batteribyte inom industrin. Till exempel är de svenska och europeiska fordonstillverkarna tveksamma eftersom det utmanar deras nuvarande affärsmodell och att de kan ta rollen som grindvakter. För det andra omfattar inte de nuvarande standarderna och regelverken för fordon och energisystem i Sverige och i EU batteribyte. Rapporten tar också upp behovet av kunskap och utbildning av personer vid batteribytesstationer, samt vikten av social hållbarhet vid elektrifiering av tunga transporter.

Bokkapitel (refereegranskat)abstract
- E-commerce presents a fantastic opportunity for consumers to receive product deliveries anytime, anyhow and anywhere. However, a major challenge for all logistics systems is that of environmental sustainability, and for e-commerce, the distribution of products to consumers constitutes one of the largest environmental challenges. This chapter focusses on green distribution alternatives for consumers, and thereby provides an overview of how e-commerce can become more environmentally sustainable through offering such alternatives. The chapter starts by pointing to two major trends behind the greening of e-commerce: the growth of e-commerce itself and the increasing societal and corporate concern for environmental sustainability. Building on a series of studies of e-commerce development on the Swedish market, the perspectives of consumers, retailers and logistics service providers paint a broad picture of e-commerce delivery. Finally, today’s as well as potential future challenges for sustainable e-commerce deliveries are discussed.
