Closed loop or ‘circular’ production systems known as Circular Economy and Cradle to Cradle represent a unique opportunity to radically revise the currently wasteful system of production. One of the challenges of such systems is that circular products need to be both produced locally with minimum environmental footprint and simultaneously satisfy demand of global consumers. This article presents a literature review that describes the application of circular methodologies to education for sustainability, which has been slow to adopt circular systems to the curriculum. This article discusses how Bachelor and Master-level students apply their understanding of these frameworks to corporate case studies. Two assignment-related case studies are summarized, both of which analyze products that claim to be 'circular'. The students' research shows that the first case, which describes the impact of a hybrid material soda bottle, does not meet circularity criteria. The second case study, which describes products and applications of a mushroom-based material, is more sustainable. However, the students' research shows that the manufacturers have omitted transport from the environmental impact assessment and therefore the mushroom materials may not be as sustainable as the manufacturers claim. As these particular examples showed students how green advertising can be misleading, applying “ideal” circularity principles as part of experiential learning could strengthen the curriculum. Additionally, this article recommends that sustainable business curriculum should also focus on de-growth and steady-state economy, with these radical alternatives to production becoming a central focus of education of responsible citizens. https://doi.org/10.1016/j.jclepro.2019.02.005 LinkedIn: https://www.linkedin.com/in/helenkopnina/

With the effects of climate change linked to the use of fossil fuels, as well as the prospect of their eventual depletion, becoming more noticeable, political establishment and society appear ready to switch towards using renewable energy. Solar power and wind power are considered to be the most significant source of global low-carbon energy supply. Wind energy continues to expand as it becomes cheaper and more technologically advanced. Yet, despite these expectations and developments, fossil fuels still comprise nine-tenths of the global commercial energy supply. In this article, the history, technology, and politics involved in the production and barriers to acceptance of wind energy will be explored. The central question is why, despite the problems associated with the use of fossil fuels, carbon dependency has not yet given way to the more ecologically benign forms of energy. Having briefly surveyed some literature on the role of political and corporate stakeholders, as well as theories relating to sociological and psychological factors responsible for the grassroots’ resistance (“not in my backyard” or NIMBYs) to renewable energy, the findings indicate that motivation for opposition to wind power varies. While the grassroots resistance is often fueled by the mistrust of the government, the governments’ reason for resisting renewable energy can be explained by their history of a close relationship with the industrial partners. This article develops an argument that understanding of various motivations for resistance at different stakeholder levels opens up space for better strategies for a successful energy transition. https://doi.org/10.30560/sdr.v1n1p11 LinkedIn: https://www.linkedin.com/in/helenkopnina/

In 1896 Svante Arhenius discovered that fossil fuels are a source of carbon dioxide. In 1965 the US Presidents science advisory panel reported that pollution is a major threat to society. In the 1970s atmospheric scientists Manabe, Wetherald and Sawyer confirmed that human activities are contributing factors to climate change. Richard Maxwell and Toby Miller explored the environmental impact of media technology in 2012. Kääpä explored sustainability in media in 2018, yet in 2022 sustainability in Film, TV and Media is still in its infancy, while other sectors are taking strong measures to reduce their carbon footprint. This report synthesis Elkington’s’ triple bottom line with Porters’ value chain in Film, TV, and media production as framework to teach sustainability. Research highlights the importance of Small Medium Enterprises (SMEs) in the sector and underscores Green Production strategies that reduce the carbon footprint. Research reveals that the sector has the unique potential to change the way audiences perceive sustainability using Green Content strategies and highlights the sustainability problem in distribution. Results suggest that educational institutions in Film, TV, and Media must do more to integrate sustainability into their curricula to unleash the full potential beyond sector boundaries.

Densely populated areas are major sources of air, soil and water pollution. Agriculture, manufacturing, consumer households and road traffic all have their share. This is particularly true for the country featured in this paper: the Netherlands. Continuous pollution of the air and soil manifests itself as acification, decalcification and eutrofication. Biodiversity becomes lower and lower in nature areas. Biological farms are also under threat. In case of mobility, local air pollution may have a huge health impact. Effective policy is called for, after high courts blocked construction projects, because of foreseen building- and transport-related NOx emissions. EU law makers are after Dutch governments, because these favoured economics and politics over environmental and liveability concerns. But, people in the Netherlands are strongly divided. The latest provincial elections were dominated by environmental concerns, next to many socio-economic issues. NOx and CO2 emissions by passenger cars are in focus. Technical means and increasing fuel economy norms strongly reduced NOx emissions to a still too high level. A larger number of cars neutralized a technological reduction of CO2 emissions. The question is: What would be the impact of a drastic mandatory reduction in CO2, NOx, and PM10 emissions on car ownership and use in the Netherlands? The authors used literature, scenario analysis and simulation modelling to answer this question. Electric mobility could remove these emissions. Its full impact will only be achieved if the grid-mix, which is still dominated by fossil fuels, becomes green(er), which is a gradual, long-term, process. EVs compete with other consumers of electricity, as many other activities, such as heating, are also electrifying. With the current grid-mix, it is inevitable that the number of km per vehicle per year is reduced to reach the scenario targets (−25% resp. −50% CO2 emissions by cars). This calls for an individual mobility budget per car user.

This chapter will introduce the circular economy (CE) and Cradle to Cradle (C2C) models of sustainable production. It will reflect on the key blockages to a meaningful sustainable production and how these could be overcome, particularly in the context of business education. The case study of the course for bachelor’s students within International Business Management Studies (IBMS), and at University College in The Netherlands will be discussed. These case studies will illustrate the opportunities as well as potential pitfalls of the closed loop production models. The results of case studies’ analysis show that there was a mismatch between expectations of the sponsor companies and those of students on the one hand and a mismatch between theory and practice on the other hand. Helpful directions for future research and teaching practice are outlined. https://www.springer.com/gp/book/9783319713113#aboutBook https://www.linkedin.com/in/helenkopnina/

The production of biogas through anaerobic digestion is one of the technological solutions to convert biomass into a readily usable fuel. Biogas can replace natural gas, if the biogas is upgraded to green gas. To contribute to the EU-target to reduce Green House Gases emissions, the installed biogas production capacity and the amount of farm-based biomass, as a feedstock, has to be increased. A model was developed to describe a green gas production chain that consists of several digesters connected by a biogas grid to anupgrading and injection facility. The model calculates costs and energy use for 1 m3 of green gas. The number of digesters in the chain can be varied to find results for different configurations. Results are presented for a chain with decentralized production of biogas, i.e. a configuration with several digesters, and a centralized green gas production chain using a single digester. The model showed that no energy advantage per produced m3 green gas can be created using a biogas grid and decentralized digesters instead of one large-scale digester. Production costs using a centralized digester are lower, in the range of5 Vct to 13 Vct per m3, than in a configuration of decentralized digesters. The model calculations also showed the financial benefit for an operator of a small-scale digester wishing to produce green gas in the cooperation with nearby other producers. E.g. subsidies and legislation based on environmental arguments could encourage the use of decentralized digesters in a biogas grid.

n the work package described in this report, members are investigating whether a cooperative of farmers can become self-sufficient in energy and fertilization by using manure and organic waste flows in combination with anaerobic fermentation. The aim is to link the nutrient cycle (from manure to digestate to green fertilizer consisting of, for example, nitrate, phosphate, potassium, and trace elements) to a self-sufficient energy system, by the combined production of electricity, green gas, green fuels, and green fertilizers. Within this research such a system is called a circular multi commodity system (CMCS). In effect linking, the nutrient cycle with an energy production chain. In addition, other energy sources and sinks can also play a role in the system such as wind, solar PV and storage (e.g. batteries or hydrogen). For this symbiosis of production techniques to succeed in practice, intensive cooperation between arable farmers and dairy farmers is needed. Farmers supply part of the input from the biofermenter and receive green fertilizers at the end of the process, which are used as a substitute for fertilizer. The case is based on a cooperative of farmers with a minimal geographical spread and maximum diversity in type of business. In this way, the current waste and nutrient chain is being replaced by a more sustainable and closed cycle. This could provide significant environmental benefits: reduction of the environmental impact through the use of fertilizer, reduction of dependence on fossil raw materials, and reduction of CO2 emissions.

Given the increasing importance of sustainability as a part of one’s daily routine and life in countries in the European Union, there is a need to establish a basic understanding of the attitudes, behaviours and culture among older people. This, in turn, should lead to better policies which help alleviate the effects of the current cost-of-living and energy crises and make our societies more sustainable and resilient. Despite the growing awareness of sustainability amongst the general public, a conceptual model of a sustainable lifestyle among older people is missing. The existing reports from the WHOprovide some guidance on how to move along, as they touch upon items that are related to sustainability such as walkability, proximity to transportation stops and emergency preparedness, and highlight the need to improve the fit between people’s needs and the environments in which they live. Any effort to come up with such a conceptual model would have to acknowledge that energy conservation and sustainable behaviours among our older population, as was shown by Bennetts et al., are not an integral part of all older people’s lifestyles and day-to-day choices. Also, following Dikken et al.,many seemingly sustainable choices may be made purely out of financial necessity. New models and policies would have to acknowledge that in times of declining purchase power, the majority of older people living on the edge make sacrifices in terms of energy use in the broadest sense of the word due to financial constraints and not out of concern for the environment.
