Using recovered energy instead of fossil fuels is a sensible direction towards a circular economy. Existing literature, while rich in technical considerations, does not analyze the decision-making process related to the wastewater infrastructure changes.

Energy Prosumers

Renewable distributed energy and self-consumption are promising and sustainable solutions in the energy-transition scenario for moving toward a circular economy. In this future scheme, prosumers are expected to play a leading role in the forthcoming sustainable energy market, facing new technical, economic, and financial challenges as energy producers at a small scale. In fact, the adoption of photovoltaic (PV) self-consumption systems requires mobilizing capital for investment and their interaction with the market. In this scenario, the aim of this paper was to explore insights into the decision-making process of prosumers to enhance the understanding of self-consumption deployment and to support effective policymaking. This study contributes to the state of the art by defining and classifying determinants of the energy prosumers’ decision-making process and their relevance using a heuristic approach. Potential measuring tools and methods are analyzed through a specific case study of Spanish prosumers.

At present, algorithms are becoming the heart of society by taking control over the decision-making process as societies are increasingly getting digitalised. There is a consistent theme that an unaccountable, black box technology has taken over the stage and is now making decisions for us, with us, and about us. But the contention around public participation in making decisions in science and technology needs to advance to a stage where there is a more direct conversation between the public and those developing the technologies. With the above mentioned conception of moderating emerging technologies’ development, primarily digital technology due to its overreaching effects on humans and what humans interpret it to be. Firstly, the research through a literature survey is aimed to understand the meaning and nuances of the word algorithm. Then the analysis based on case study is focused on the algorithmic questions, such as bias, privacy, design, transparency, and accountability. In a larger context, concerns over jobs, ways of social interactions, etc., had been discussed, since these concerns are the result of the application of algorithms. The analysis of academic literature pointed out the vital facet of multiple understanding of the word algorithm. Further, the research also emphasizes the meaning of philosophy and politics in technology and its non-neutral nature.

Energy Economy

Conventional energies are directly related to the use of fossil fuels, generating this type of energy entails alarming economic and environmental costs. Based on this, the transition to clean energy, implies modifications in the energy labour market. Specifically, we studied the large labour market that the solar industry can generate in Mexico, with the help of the 3R's methodology, we have adapted it to a circular economy focusing on the solar panels could be the main technology for this sector.

AbstractIn accordance with sustainable economic and social development, Europe supports the use of energy from renewable sources to decrease the use of fossil fuels. Among renewable energy sources, wood, especially production wood waste from the supply chain, represents an exploitable source in line with a circular economy development. In this context, processing of residues produced by wood companies becomes an important resource. This work deals with the possible energy recovery of glued wood wastes. Two solid biofuels were produced from glued wood wastes: pellets and briquettes. They have been produced in collaboration with a local company and analyzed according to the applicable EN ISO international standards. The results were compared with the limits imposed by the standards in order to identify their quality class and their applicability to the current market. The amount of adhesive present in the wood wastes does not negatively affect the intrinsic characteristics of the material that is suitable for the production of solid biofuels. In addition, the amount of wood waste containing cross-linked polyurethane was calculated in order not to compromise the quality of solid biofuels made therefrom.

This case study explores the strategic business opportunities, for Lane Crawford, an iconic luxury department store, to transition in a circular economy towards sustainability. A new experimentation framework was developed and conducted among cross departmental employees, during a Design Lab, with intention to co-create novel Circular Economy business concepts towards a new vision: the later was a reframe of the old system based on the principles of sustainability; to move beyond a linear operational model towards a circular economy that can contribute to a regenerative society. This work draws on both academic and professional experience and was conducted through professional practice. It was found that innovative co-created concepts, output from the Design Lab, can create radical change in a circular economy that is holistically beneficial and financially viable; looking forward to extract greater value a)Internal organization requires remodeling to transform towards a circular economy; b)Requirement for more horizonal teams across departments vs solely vertical; c)New language and relationships are required to be able to transition towards a circular economy; d)Some form of physical and virtual space requirements, for cross-disciplinary teams to come together to co-create; e)Ability to iterate, learn and evolve requires agency across the business
