The increasing accumulation of synthetic plastic waste in oceans and landfills, along with the depletion of non-renewable fossil-based resources, has sparked environmental concerns and prompted the search for environmentally friendly alternatives. Biodegradable plastics derived from lignocellulosic materials are emerging as substitutes for synthetic plastics, offering significant potential to reduce landfill stress and minimise environmental impacts. This study highlights a sustainable and cost-effective solution by utilising agricultural residues and invasive plant materials as carbon substrates for the production of biopolymers, particularly polyhydroxybutyrate (PHB), through microbiological processes. Locally sourced residual materials were preferred to reduce transportation costs and ensure accessibility. The selection of suitable residue streams was based on various criteria, including strength properties, cellulose content, low ash and lignin content, affordability, non-toxicity, biocompatibility, shelf-life, mechanical and physical properties, short maturation period, antibacterial properties and compatibility with global food security. Life cycle assessments confirm that PHB dramatically lowers CO₂ emissions compared to traditional plastics, while the growing use of lignocellulosic biomass in biopolymeric applications offers renewable and readily available resources. Governments worldwide are increasingly inclined to develop comprehensive bioeconomy policies and specialised bioplastics initiatives, driven by customer acceptability and the rising demand for environmentally friendly solutions. The implications of climate change, price volatility in fossil materials, and the imperative to reduce dependence on fossil resources further contribute to the desirability of biopolymers. The study involves fermentation, turbidity measurements, extraction and purification of PHB, and the manufacturing and testing of composite biopolymers using various physical, mechanical and chemical tests.

Every year, tens of millions of the 1.4 billion cars on the world’s roads are decommissioned. While the ferrous and other metals that constitute about 75% of a vehicle by weight can be readily and profitably recycled, the remaining mix of plastics, glass, composites, complex materials, fragments and contaminants are mainly destined for landfill as automotive shredder residue (ASR). For every car, approximately 100–200 kg of ASR is disposed of in landfill, posing a growing technical and environmental challenge worldwide. The recovery of the ASR for high-end application is the focus of this study, aiming to optimise the use of these valuable resources and minimise the extractive pressure for raw materials, a future green manufacturing, contributing towards a zero waste circular economy. As the dissolution of carbon into iron is a key step in the manufacture of iron-carbon alloys, the feasibility of utilizing the waste polymers within ASR as sources of carbon in different areas of pyrometallurgical processing was investigated. Polypropylene and rubber, in a blend with metallurgical coke, were used as carbonaceous substrates and the slag-foaming phenomenon was investigated via the sessile drop technique in an argon environment at 1,550°C. The results indicated the rubber/coke blend achieved significantly better foaming behaviour, and the PP/coke blend exhibited a moderate improvement in slag foaming, in comparison to 100% metallurgical coke. The overall results indicated the incorporation of ASR had significant improvement in foaminess behaviour, increasing furnace efficiency.

In today's world, events are used as a mean to achieve an array of objectives including changing behaviours. This chapter asserts the importance of marketing in encouraging sustainable behaviours by children through events. Thus, it examines the most effective way of marketing to contribute to shift behaviours in a young age having events as an ally. The question that poses is how marketing and more specifically social marketing can help to plan, create, design and promote sustainable events for children. Bearing that in mind, and based on a semi-systematic literature review, one developed a comprehensive conceptual framework intending to show how it is possible to encourage sustainable children's behaviour through events. Results suggest that social marketing can play a significant role in changing children's behaviour towards sustainability. It is argued that there is a creation of ‘value’ even that behaviour change is only temporary. Furthermore, it is suggested that social marketing represents a viable approach when seeking to educate children and change their behaviours towards the adoption of more sustainable practices. This chapter advances theoretical knowledge by offering a conceptual framework and by suggesting a way forward in marketing sustainable events for children.

The aim of this chapter is to introduce the reader to the complexities of marketing organization especially in bigger firms. This chapter draws attention to one of these major drivers for change — globalization. This is done with the help of an in-depth case study of ABB Robotics.

The case describes how a change is achieved through a major marketing reorganization process. Initially, there are major difficulties grasping the organizational problem and identifying its causes. Many different organizational “issues” are part of the problem in the multifaceted case. Relying on complexity theory, the case suggests that a more complex environment with greater number of relevant players, which are — themselves — interconnected through networks, will also exhibit a greater range of change. Change and reorganization processes like the one confronting the case company would rather be the normal situation for companies embedded in complex global networks.

The purpose of this paper is to examine the ways in which academic researchers frame and conduct sustainability research and to ask to what extent we are limited by these frames.

Our approach is based on an epistemological critique. We begin with a discussion of the ways in which sustainable consumption has been conceptualised within marketing; we question the influence of positivist social science research traditions and examine how research on sustainability is impacted by the structure of academia.

Our critical reflection leads us to suggest three ways in which sustainability research might be re-framed: a reconsideration of language, a shift in the locus of responsibility and the adoption of a holistic approach.

We propose that in order to make progress in sustainability research, alternative frames, terms, units of analysis, method(ologies) and research ambitions are needed.

By making visible our collective, unexamined assumptions, we can now move forward with new questions and agendas for sustainability research.

Composites based on fiber are commonly used in high-performance building materials. The composites mostly use petrochemically derived fibers like polyester and e-glass, due to their advantageous material features like high stiffness and strength. All the same, these fibers also have important shortcomings related to energy consumption, recyclability, initial processing expense, resulting health hazards, and sustainability. Increasing environmental awareness and new sustainable building technologies are driving the research, development, and usage of “green” building materials, especially the development of biomaterials.

In this chapter, the natural fiber evaluation approach is applied, which covers a diverse set of criteria. Consequently, the comparative assessment of diverse natural fiber types is applied through the use of an expert decision system approach. The best performing fiber choice is made by comparatively evaluating the materials related to green building. The proposed fiber can be used and applied by green building material manufacturing companies in various countries or locations as a reference when selecting the fiber with the best performance.

Austerity in Greece has produced the ostensibly counterproductive effect of throwing the country into a deeper depression and rendering it more difficult to repay its debts. I address this apparent paradox by examining both the integration of Greece into the European Monetary Union and post-crisis austerity measures with a particular focus on the Greek credit system. I do so by employing a historical materialist framework focusing on Marx’s concept of ‘fictitious capital’, capital not backed by a commodity transaction, but by a claim on future value. I argue that, while the crisis is overdetermined, one hitherto unexplored dimension is the rapid expansion of the Greek credit system in the 1990s and 2000s. More specifically, Greek banks expanded to neighbouring countries, and borrowing by households and firmed spiked dramatically after Greece adopted the Euro, but a number of domestic political-economic factors acted as drags to this process. In this context, I argue that the crisis has served as an opportunity to impose a radically accelerated restructuring of the Greek economy in line with the ideal neoliberal utopia. This can be understood as one of the three responses to a crisis of fictitious capital: internal devaluation, asset devaluation or upward. However, the success of this project is far from guaranteed, so far the austerity project pursued by the troika has failed to replace the old Greek balance of social forces that have dominated the post-junta political economy of Greece.
