Improving sustainability performance and adapting to circular economy principles in operational business strategies are becoming increasingly prioritized. In this pursuit, the concept of industrial symbiosis (IS) has become increasingly relevant. IS represents a collaborative approach where the interplay of material, residual waste, energy, and infrastructure exchanges aims to yield not only economic and environmental advantages for the participating companies but also substantial societal benefits by using resources more efficiently. Biogas production is such an example, it can reduce greenhouse gas emissions since it can produce heat and electricity, replace renewable fuel for vehicles, or be used as input material for industrial use. The digestate from biogas production can also be used as an effective agricultural fertilizer to replace chemical fertilizers which are produced using fossil energy.

Digital tools and platforms in IS can be used to different extent depending on businesses levels of digital maturity (the extent to which businesses adapt to ongoing digital change and integrate digitalization). Digital tools and platforms hold a central role for developing various advantages in biogas-based IS, but since the digital maturity for IS focusing on biogas production is uncertain, the current efficiency obtained by tools and platforms is unknown. Therefore, through semi-structured interviews and study visits, this study assesses stakeholder collaboration and use of digital tools at five IS sites with biogas production in Sweden. It explores (i) current digital maturity and collaboration characteristics amongst established biogas-based IS, and (ii) needs amongst stakeholders for development of digital tools and platforms to promote digital maturity, monitoring, collaboration, and knowledge exchange in current and future IS structures.

Preliminary results of the on-going study show that the use of digital tools varies depending on the character and size of resource flows that are included in the collaboration, and due to the internal digital maturity of the involved companies. In general, the use of digital tools for stakeholder interaction is on low or medium level, in which manual handling is required and little is automated. This complies with the sites being relatively small, and the number of stakeholders involved are relatively few. Moreover, the preliminary results show that the interest of future development of digital tools is found to be related to business development and expanded market opportunities through diversified raw material use, increased production, and new distribution channels. In addition, a demand of digital platforms for exchange of experience and competence supply has been identified.

Perception and awareness can affect behaviour and decision-making, for example, how companies implement Circular Economy (CE) practices. However, there is limited empirical research about this topic. Thus, we investigated the perception and awareness of representatives from water-intensive and bio-based sectors regarding the CE concept based on interviews and a survey with 10 companies in Sweden. Our results indicate that CE is understood mainly as zero waste and its key principles are resource efficiency and ecodesign. Missing (or partially addressed) important elements of CE are consumption, social aspects, regenerative role of CE, collaboration, and Industrial Symbiosis. The main benefit from implementing circular strategies is economic, and the main barrier is the lack of financial resources. The bio-based companies have a broader understanding of CE and its benefits than the water-intensive companies. Overall, more clarification and standardisation of the CE concept is necessary to avoid misunderstanding with other concepts such as sustainability. © 2024 The Authors

The measurement of progress towards Circular Economy (CE) within a company is crucial for identifying opportunities and designing circular practices. However, most of the existing tools do not consider the systemic view and principles of CE. The aim of this paper is to assess the contributions and limitations of CE assessment tools regarding the key elements: social dimension, stakeholder engagement, R-imperatives and industrial symbiosis. Also, the aim is to offer guidance for improvements towards a CE transition. The methodology was an integrative literature review; then based on the critical assessment of tools a guide was created. Thirty-eight tools were thoroughly analysed and our results show that there is a limited number of multidisciplinary tools (only 10), that is including all CE key elements, and in some cases partly. Social dimension is not fully explored; only 6 tools have indicators related to society, local community, customers, and workers. Recommendations for future tools development include to offer training for possible users of the tools and to develop tools for the service sector. Finally, we conclude that all the key elements of CE are interconnected. The proposed guide-ACTION (Assessing Circular Transition In Organisations Now)- includes the key elements, databases, tools, and indicators, and is aligned with the CE principles to help the assessment. © 2022 The Author(s)

Efforts to mitigate greenhouse gas (GHG) emissions are receiving increased attention among governmental and commercial actors. In recent years, the interest in paludiculture, i.e. the use of rewetted peatlands, has grown because of its potential to reduce GHG emissions by stopping soil decomposition. Moreover, cultivating wetland plants on rewetted peatlands for  bioenergy production that replaces fossil fuels in the transport sector, can contribute to additional GHG emission reductions. In this study, an analysis of literature data was conducted to obtain data on GHG emissions (CO2 and CH4) and biomass production from rewetted peatlands cultivated with two different wetland plant species: Phragmites australis (Pa) and Typha latifolia (Tl). In  addition, a  biogas experiment was carried out to investigate the biomethane yield of Pa and Tl biomass, and the reduction of global warming potential (GWP) by using biomethane as vehicle fuel. The results show that peatland rewetting can be an important measure to mitigate the GWP as it reduces GHG emissions from the soil, particularly on a 100-year timescale but also to some extent on a 20-year timescale. More specifically, rewetting of 1 km2 of peatland can result in  a  GWP reduction corresponding to  the  emissions from ±2600 average sized petrol cars annually. Growing Pa on rewetted peatlands reduces soil GHG emissions more than growing Tl, but Pa and Tl produced similar amounts of biomass and biomethane per land area. Our study concludes that Pa, because of a more pronounced GWP reduction, is the most suitable wetland plant to cultivate after peatland rewetting. © 2020 The Author(s). Published by Elsevier Ltd.

Farm-based biogas production is a promising renewable energy technology with the potential for creating sustainable economic, environmental, and social value. However, Swedish farmers engaged in this activity struggle to turn a profit because of high-investment costs and severe price competition with fossil fuels. One way to address this situation is to re-organize the activity by innovating the business model (BM) towards sustainability. In this study, a team of researchers took an action research approach that proposed solutions for the financial difficulties at a farm cooperative that intended to develop its farm-based biogas production. Two participatory workshops (including researchers, producers, students, and consultants) were conducted using the sustainable business-modelling tool called the Flourishing Business Canvas (FBC). Based on the 215 ideas developed in the workshops, five sustainable BM prototypes were created. These five prototypes form the basis of an approach for initiating the development of a network-level BM for sustainability that highlights its superiority over a single-firm BM. The network-level BM’s main advantage in the farm-based biogas context is its strong focus on stakeholder collaboration that supports the development of a stakeholder business case for sustainability. Overall, this study highlights the usefulness of the network concept in the practice of sustainable BM development. Collaborative business modelling for developing network-level BMs that address environmental and social problems for and with stakeholders can be an effective way to increase long-term financial profit and promote the growth of a firm, a network, or an industry. © 2018 The Author(s)

Global warming along with energy demand and rising prices of natural energy resources have motivated studies to find some renewable and clean energy. The use of algae as the third-generation biofuel can avoid the competition for farmland, and algae can be considered as a potential future source of renewable energy. Algae can be used for biogas production through anaerobic digestion (AD). Fucus vesiculosus and Fucus serratus are the two dominating species of brown seaweed growing in the Baltic Sea in the southwest of Sweden. Pretreatment can significantly affect the biogas production because hydrolysis of the algae cell wall structure is a rate-limiting step in the AD process. In this study, four different pretreatments: mechanical, microwave (600 W, 2 min), ultrasonic (110 V, 15 min), and microwave combined with ultrasonic (600 W, 2 min; 110 V, 15 min) were applied to the seaweed and then codigested with a biogas plant leachate. The aim of this study was to investigate methane yields from AD after these pretreatments. The results showed that when compared with only mechanical pretreatment, the ultrasonic, ultrasonic combined with microwave, and microwave pretreatments could obtain increased cumulative methane yields of 167, 185, and 156%, respectively. The combined pretreatment showed a maximum methane yield of 260 mL/g·of volatile solids after 20 days of digestion. The ultrasonic combined with microwave pretreatment showed a significant improvement in methane yield when compared with the mechanical pretreatment. Copyright © 2019 American Chemical Society

In recent years in Sweden, interest has grown concerning the possibilities of biogas production from organic waste. This interest reflects a general concern over environmental sustainability in society. However, given the lack of financial backing and the competition of other energy producers, few Swedish biogas plants have been profitable. This is particularly the situation with farm-based biogas producers. One response to this problem in the farm-based biogas industry is to engage in business model innovation that can lead to new ways of organizing business structures and activities. This qualitative study, which takes an action research approach, explores the early phases (initiation and ideation) of the business model innovation process for sustainability at a biogas-producing farm cooperative in southern Sweden. The main activities and the actors who are central to the execution of these activities are identified in six sub-phases. The paper describes two Flourishing Business Canvas workshops in which the participants were the researchers, members of the farm cooperative, external consultants, and university students. This study contributes theoretically to the literature with its detailed examination of the early phases of the business model innovation process for sustainability. It also contributes to practice with its conceptual model that demonstrates how biogas producers and farm managers can innovate and transform their current business models towards sustainability in order to improve competitiveness and long-term profitability.

As companies and other organizations increasingly recognize society’s demand for greater social and environmental sustainability, university and college business schools have responded with new pedagogic approaches. Business schools have begun to offer courses in business models and business model innovation that focus not only on profit-normative goals but also on social and environmental goals. This paper describes an Experiential Workshop for university undergraduates in which the Service-Learning pedagogic approach is taken and Flourishing Business Canvas is applied as a tool for collaborative visual business modelling. In the Workshop, the students work with business model innovation for a biogas production cooperative of farmer-members in southern Sweden. The students take the role of problem-owners and problem-solvers as they co-create new business models ideas for the cooperative. The paper presents the students’ achievement of three Learning Objectives as they engage in meaningful, “real-world” simulations with a high degree of autonomy that allows them to combine their theoretical knowledge with practice. Implications for educators who wish to test the Experiential Workshop in their classrooms are proposed. The paper concludes with the suggestion that Education for Flourishing is a useful expansion of Education for Sustainable Development. © 2017 Elsevier Ltd. All rights reserved.
