Food-processing companies are controlled by societal influences and economic interests, but their efforts with regard to reducing food loss and waste are very different. This qualitative study aims to identify basic recommendations of good practice for the food-processing industry in order to prevent and handle food loss and waste. For this purpose, a comprehensive literature review was conducted in the field of food waste prevention and data was collected from thirteen German companies. The findings summarize the recommendations of good practice, which cover the entire supply chain from supplier to consumer and beyond. The analysis showed that the participating companies are already partially aware of operational measures, even if they are applied or mentioned without a systematic approach. Furthermore, the analysis revealed that most activities relate to internal matters, like processing, employees and utilization. However, the responsibility of foodprocessing companies does not end with internal processes to reduce food waste. The results show that some companies are already aware of their responsibility to be involved along the entire supply chain. Finally, the results show that the needs of consumers and suppliers must also be considered in order to reduce food waste, in addition to direct reduction measures. This paper highlights nine important stages and 53 basic recommendations for companies to address food loss and waste in order to improve their practices.
Background. Ketone bodies are a highly relevant topic in nutrition and medicine. -e influence of medium-chain triglycerides (MCT) on ketogenesis is well known and has been successfully used in ketogenic diets for many years. Nevertheless, the effects of MCTs and coconut oil on the production of ketone bodies have only partially been investigated. Furthermore, the increased mobilisation of free fatty acids and release of catabolic hormones by caffeine suggest an influence of caffeine on ketogenesis.
Methods. In a controlled, double-blind intervention study, seven young healthy subjects received 10mL of tricaprylin (C8), tricaprin (C10), C8/C10 (50% C8, 50% C10), or coconut oil with or without 150 mg of caffeine, in 250mL of decaffeinated coffee, over ten interventions. At baseline and after every 40 minutes, for 4 h, ßHB and glucose in capillary blood as well as caffeine in saliva were measured. Furthermore, questionnaires were used to survey sensory properties, side effects, and awareness of hunger and satiety. Results. -e interventions with caffeine caused an increase in ßHB levels—in particular, the interventions with C8 highly impacted ketogenesis. -e effect decreased with increased chain lengths. All interventions showed a continuous increase in hunger and diminishing satiety. Mild side effects (total � 12) occurred during the interventions. Conclusions. -e present study demonstrated an influence of caffeine and MCTon ketogenesis. -eaddition of caffeine showed an additive effect on the ketogenic potential of MCT and coconut oil. C8 showed the highest ketogenicity.
Coworking Spaces sind mittlerweile fester Bestandteil der digitalen Arbeitslandschaft in Großstädten. Nach und nach halten sie auch im ländlichen Raum Einzug. Studien und Modellprojekte haben bewiesen, dass sie sowohl gesellschaftlich als auch wirtschaftlich eine positive Wirkung auf strukturschwächere Regionen haben können. Sie bieten ein attraktives Umfeld für Kreative und Gründer und ermöglichen den Austausch mit lokalen Unternehmen. Außerdem können sie dafür sorgen, dass Pendler* innen zum Arbeiten vor Ort bleiben.
In weniger dicht besiedelten Regionen, wie dem Münsterland, ist der profitable Betrieb von Coworking Spaces bisweilen schwierig. Da naturgemäß die Standortwahl eines Coworking Space ein entscheidendes Kriterium für seine spätere Wirtschaftlichkeit ist, wird diese in der vorliegenden Studie untersucht. Dazu werden auf Coworking Spaces zugeschnittene und von Experten gewichtete Standortfaktoren aufgestellt und die 65 Orte des Münsterlands anhand dieser Faktoren bewertet. So entsteht ein Ranking, welches aufzeigt, wo die besten Voraussetzungen für Coworking Spaces herrschen.
In einigen Städten im Münsterland gibt es bereits Coworking Spaces. Einem Großteil dieser Orte wird durch diese Studie eine gute Eignung bestätigt. Beispielsweise schneiden Rheine und Bocholt aufgrund ihrer hohen Einwohnerzahl am besten ab. Es wird jedoch deutlich, dass auch andere Faktoren ausschlaggebend sein können. So bewerten Expert*innen die digitale Infrastruktur und Erreichbarkeit als sehr wichtig. Für diese Faktoren stellen vergleichsweise kleine Orte die Bestwerte, die bislang noch keine Coworking Spaces vorweisen können.
Die Ergebnisse informieren Betreiber*innen von Coworking Spaces und solche, die es werden wollen, sowie politische Entscheidungsträger*innen über mögliche Potenziale in den jeweiligen Orten. Sie zeigen auf, an welchen Stellschrauben gedreht werden kann, um gute Voraussetzungen zu schaffen. Darüber hinaus wird empfohlen, das entstehende Angebot aufeinander abzustimmen und gemeinschaftlich vorzugehen – so, wie es der Begriff Coworking bereits verdeutlicht.
Introduction: Many disease processes are accompanied and promoted
by increased inflammation in the body. Increased concentrations of high-sensitivity C-reactive protein (hs-CRP) in the blood are an indicator of subclinical inflammation, increased disease risk, and an increased risk of early death. A healthy plant-based diet and increased physical activity have been shown to reduce hs-CRP concentrations.
Objectives: Our objective was to test if a healthy lifestyle intervention program can improve hs-CRP levels and other risk factors.
Methodology: We are conducting a non-randomized, controlled intervention study with 6 times of measurement (baseline, after 2.5, 6, 12, 18 and 24 months). Participants in the intervention group (n = 104) took part in a 2.5-month intensive lifestyle program focusing on a plant-based diet (PBD), physical activity, stress management and group support. Currently they are in the less intensive phase (monthly seminars) which will be completed after 24 months. The control group (n = 62) did not take part in any program. In both groups hs-CRP was assessed, and participants with an infection/common cold at any of the times of measurement were excluded from the analyses.
Results: In the intervention group (n = 97) we observed a reduction in hsCRP from baseline to 2.5 months (p < 0.001). In the control group (n = 46) hs-CRP levels increased non-significantly. The changes from baseline to 2.5 months were significantly different between intervention and control (p < 0.01).
Conclusion: Our program led to a clinically relevant reduction in hs-CRP.
Continued follow-up will show if this improvement can be maintained in the intervention group. Our study confirms that a PBD and healthier lifestyle choices can lower hs-CRP.

In this paper, we scrutinise the sharing economy from a moral householding perspective and evaluate the moral justifications for a sustainable form of the sharing economy. We consider the emergence of normative moral justifications through householding practices that rest on local mobilisation of people in defence of communities and commitments against the adverse impacts of neoliberal market capitalism.
Our perspective draws on Karl Polanyi's conceptualisation of householding, that is, autarchic, communistic provision in a closed community. Using timebanking as an example, we illustrate how a moral sharing economy can be mobilised in collective battles against the current neoliberal system of economic crisis. We contribute to the amassing sharing economy literature emphasising a central, yet missing element of the current discourse: householding as practices creating self-sufficiency and autonomy as well as combining both kin and stranger.
The United Nations formulated the sustainable development goals (SDGs) in 2015 as a comprehensive global policy framework for addressing the most pressing social and environmental challenges currently facing humanity. In this paper, we analyse SDG 12, which aims to ‘‘ensure sustainable consumption and production patterns.’’ Despite long-standing political recognition of this objective, and ample scientific evidence both on its importance and on the efficacy of various ways of promoting it, the SDGs do not provide clear goals or effective guidance on how to accomplish this urgently needed transformation. Drawing from the growing body of research on sustainable consumption and production (SCP), the paper identifies two dominant vantage points—one focused on promoting more efficient production methods and products (mainly through technological improvement and informed consumer choice) and the other stressing the need to consider also overall volumes of consumption, distributional issues, and related social and institutional changes. We label these two approaches efficiency and systemic. Research shows that while the efficiency approach contains essential elements of a transition to sustainability, it is by itself highly unlikely to bring about sustainable outcomes. Concomitantly, research also finds that volumes of consumption and production are closely associated with environmental impacts, indicating a need to curtail these volumes in ways that safeguard social sustainability, which is unlikely to be possible without a restructuring of existing socioeconomic arrangements. Analysing how these two perspectives are reflected in the SDGs framework, we find that in its current conception, it mainly relies on the efficiency approach. On the basis of this assessment, we conclude that the SDGs represent a partial and inadequate conceptualisation of SCP which will hamper implementation. Based on this determination, this paper provides some suggestions on how governments and other actors involved in SDGs operationalisation could more effectively pursue SCP from a systemic standpoint and use the transformation of systems of consumption and production as a lever for achieving multiple sustainability objectives.
Technological solutions to the challenge of dangerous climate change are urgent and necessary but to be effective they need to be accompanied by reductions in the total level of consumption and production of goods and services. This is for three reasons. First, private consumption and its associated production are among the key drivers of greenhouse-gas (GHG) emissions, especially among highly emitting industrialized economies. There is no evidence that decoupling of the economy from GHG emissions is possible at the scale and speed needed. Second, investments in more sustainable infrastructure, including renewable energy, needed in coming decades will require extensive amounts of energy, largely from fossil sources, which will use up a significant share of the two-degree carbon budget. Third, improving the standard of living of the world’s poor will consume a major portion of the available carbon allowance. The scholarly community has a responsibility to put the issue of consumption and the associated production on the research and policy agenda.
Power: the missing element in sustainable consumption and absolute reductions research and action
(2016)
In this essay, we aim to demonstrate the value of a power lens on consumption and absolute reductions. Specifically, we illuminate what we perceive to be a troublesome pattern of neglect of questions of power in research and action on sustainable consumption and absolute reductions. In pursuit of our objectives, we delineate how many of the informal and implicit “theories of social change” of scholars and activists in sustainable consumption and sustainable development fail to address power in a sufficiently explicit, comprehensive and differentiated manner and how that failure translates into insufficient understandings of the drivers of consumption and the potential for and barriers to absolute reductions. Second, we develop the contours of a power lens on sustainable consumption. Third, we illustrate the value of such a power lens, with a particular focus on the case of meat consumption.
Veblen’s concept of conspicuous consumption is often cited to explain why consumption habits in our consumer societies tend to be unsustainable and ever increasing. However, much more than blaming individual consumption habits Veblen sharply analyzed quite some of the societal and economic forces which drive the framework conditions for un-sustainable consumption: the vested interests and the absentee ownership. The paper follows the path Veblen’s thoughts have taken trough economic and social literature over the last centuryand highlights how the actual sustainable consumption debate could make better use of Veblen’s insights e.g. in requesting the constitutive institutions for property. Opportunities for Strong Sustainable Consumption obviously presuppose radical changes, social innovations and thinking out of the box.
The paper looks at NGOs activities in Sustainable Production and
Consumption and obstacles being faced. It identifies lessons for policymakers seeking to engage civil society and makes recommendations on how academics can co-operate more effectively with civil society. Insights are drawn from recent studies on stakeholder involvement in the international political process and a series of surveys and semi-structured interviews. The authors identify four challenges. Effort should (1) be planned more strategically, (2) link sustainable consumption to current priorities, (3) ensure better links between global and local and (4) NGOs have to better link to other interest groups.
Actual initiatives to cultivate more sustainable modes of consumption have not materialized and there are indications that an implementation gap is becoming manifest.
Research must begin to systemically integrate initiatives to promote improvements in quality of life, to distinguish long-term structural consumption trends, and to identify the social mechanisms and cultural aspects of consumer behavior and household decision making.
What are the implications of the current international political, and
economic settings for consumer policy, and, in particular, those regarding sustainable consumption? In terms of improvements in the efficiency of consumption, the settings have induced efforts to this effect and show potential for further progress. In terms of necessary changes in consumption levels and patterns, however, little progress has been made since the Rio Summit nor is there likely to be any in the near future. These two dimensions of sustainable consumption need to be differentiated, as there is a substantial amount of controversy regarding our ability to achieve sustainable consumption on the
basis of improvements in efficiency alone. The paper traces these differences with respect to the work of the major international governmental organizations (IGOs) engaged in developing sustainable consumption governance. It argues that the lack of commitment
to strong sustainable consumption among IGOs can be explained by their ‘‘weakness’’ as actors in global governance and the existence of strong opposing interests among consumers and business actors.
Contemporary food production and consumption cannot be regarded as sustainable and raises problems with its wide scope involving diverse actors. Moreover, in the face of demographic change and a growing global population, sus-tainability problems arising from food systems will likely become more serious in the future. For example, agricultural production must deal with the impacts of climate change, increasingly challenging land-use conflicts, and rising health and social costs on both individual and societal levels. The unsustainability of current arrangements arises from the industrialization and globalization of agriculture and food processing, the shift of consumption patterns toward more dietary animal protein, the emergence of modern food styles that entail heavily processed products, the growing gap on a global scale between rich and poor, and the paradoxical lack of food security amid an abundance of food. These factors are attributable to national and international policies and regulations, as well as to prevalent business prac-tices and, in particular, consumers’ values and habits. The most effective ways for affluent societies to reduce the environmental impact of their diets are to reduce consumption of meat and dairy products (especially beef), to favor organic fruits and vegetables, and to avoid goods that have been transported by air on both individual and institu-tional levels (e.g., public procurement, public catering). In examining the unsustainability of the current food system this article reviews the pertinent literature to derive a working definition of sustainable food consumption, outlines the major issues and impacts of current food-consumption practices, and discusses various policy interventions, including information-based instruments, market-based initiatives, direct regulations, and “nudges.” It concludes with a call for integrative, cross-sectoral, and population-wide policies that address the full range of drivers of unsustainable food production and consumption.
It is increasingly obvious that for safeguarding environmental sustainability, eco‐efficiency measures will need to be complemented by sufficiency, in particular by strong sustainable consumption. The Theory of Planned Behaviour TPB and Social Practice Theory SPT offer different views on consumer behaviour, and on ways to change it. This paper briefly describes the challenges, discusses the applicability of both theories and their meaningfulness for policy recommendations.
We suggest an approach combining results of both bodies of theory, complemented by ideas from political economy, to substantiate the Prism of Sustainable Consumption we introduce as a heuristic sufficiency policy tool. It is useful to identify affordability criteria for change in each dimension, as the basis for deriving suggestions for effective policy interventions. We conclude
that (i) effective interventions are possible, (ii) they have to address several dimensions of affordability simultaneously, and (iii) the sufficiency policy space prism can be a useful tool in structuring planned interventions.
Experience shows that energy savings through energy efficiency measures are partly compensated by income growth, and partly by rebound effects. Therefore to be effective, efficiency measures have to be embedded in a concept of sufficiency which strives for limits and absolute reduction of energy consumption. While the sufficiency concept is not new, it only recently gained attention in the field of housing. This paper provides a basis for broader and more informed debates in policy and research on the potential of sufficiency considerations to contribute to the overall reduction of energy consumption in the residential sector. It recommends shifting the attention from energy consumption of buildings towards a concept of sustainable homes in which e.g. the size of the living area plays a crucial role. A further important aspect is the possibility to fulfil other basic needs like the provision with food, recreation and social contacts in the nearby environment. The paper describes first examples of housing projects guided by sufficiency criteria, depicts the potential roles of different actor groups and points towards some general policy recommendations.
Improving residential energy efficiency is widely recognized as one of the best strategies for reducing energy demand, combating climate change and increasing security of energy supply. However, progress has been slow to date due to a number of market and behavioural barriers that have not been adequately addressed by energy efficiency policies and programmes.
This study is based on updated findings of the European Futures for Energy Efficiency Project that responds to the EU Horizon 2020 Work Programme 2014-15 theme 'Secure, clean and efficient energy'. This article draws on five case studies from selected European countries - Finland, Italy, Hungary, Spain, and the UK - and evaluates recent energy efficiency developments in terms of indicators, private initiatives, and policy measures in the residential sector. Our analysis shows that the UK government has implemented a better range of policies, coupled with initiatives from the private sector, aimed at improving energy efficiency. However, its existing conditions appear to be more problematic than the other countries. On the other hand, the lack of effective and targeted policies in Finland resulted in increased energy consumption, while in Hungary, Spain and Italy some interesting initiatives, especially in terms of financial and fiscal incentives, have been found.
