Sustainability considerations for organic electronic products.

The development of organic electronic applications has reached a critical point. While markets, including the Internet of Things, transparent solar and flexible displays, gain momentum, organic light-emitting diode displays lead the way, with a current market size of over $25 billion, helping to create the infrastructure and ecosystem for other applications to follow. It is imperative to design built-in sustainability into the materials selection, processing and device architectures of all of these emerging applications, and to close the loop for a circular approach. In this Perspective, we evaluate the status of embedded carbon in organic electronics, as well as options for more sustainable materials and manufacturing, including engineered recycling solutions that can be applied within the product architecture and at the end of life. This emerging industry has a responsibility to ensure a 'cradle-to-cradle' approach. We highlight that ease of dismantling and recycling needs to closely relate to the product lifetime, and that regeneration should be facilitated in product design. Materials choices should consider the environmental effects of synthesis, processing and end-product recycling as well as performance

Design, health and circular economy.

Products generate waste in a linear value production model design. New sustainable design methods focus on using bio-materials and re-manufacturing processes to decrease waste and impact on the environment. Circular Economy models are sustainable because they aim to keep the value of a product at the end of their useful life. They reintegrate products in the chain instead of becoming waste and lose their value. However, circular models require an understanding of the big picture of business model ecosystems on what, who and how everyone closes the loop. Furthermore, the Internet of Things in product-service systems (PSS) requires the integration of diverse perspectives in their conception and design. The objective of this thesis is to find a way to create circular PSS concepts in circular economy models through a collaborative design approach. The approach extracts the expertise of other areas to understand the real needs of all stakeholders to close the gap between design and business perspectives. It aims to understand what value means for each stakeholder, the implications of moving towards circular economy models, the impact on the product architecture, the technological trends opportunities and the experiences that the users and customers desire. The study case for the thesis focuses on chronic diseases in Finland, especially for ischemic heart diseases which are the leading cause of deaths triggered by a cardiac arrest. The cardiopulmonary resuscitation (CPR), and the automated external defibrillator (AED) are fundamental to save a life. Methods, tools and principles of PSS and circular models, combined with Human-Centred Design (HCD) approaches, identify a problem space and possible solutions for circularity and usability in the study case. The limits of this research are that the time scope for the project only reached the design concept stage, without the implications of standards for medical equipment for a future product development stage. The outcomes of the research are insights for CPR and AED as a product-service system in circular economy models. However, the principal value is a new canvas that analyses a product -from the perspectives of design, business and technology- to map all the implications required to transform a product into a PSS in a circular model; integrating experts in a collaborative workshop to validate the model. The complexity of product-service systems in circular models resides in their natural transdisciplinarity. The number of stakeholders and their expertise surpass the knowledge of design to understand their processes. Alongside the contribution of the new canvas, the main conclusion for this work is that transdisciplinary projects could be led through the collaborative design approach under two conditions. The first condition is when the designer understands the meanings of concepts across disciplines, and secondly when the project has access to all the critical stakeholders in the project’s ecosystem. Thus, the need for transdisciplinary tools for design approaches requires further analysis and development

A conceptual framework for circular design

Design has been recognised in the literature as a catalyst to move away from the traditional model of take-make-dispose to achieve a more restorative, regenerative and circular economy. As such, for a circular economy to thrive, products need to be designed for closed loops, as well as be adapted to generate revenues. This should not only be at the point of purchase, but also during use, and be supported by low-cost return chains and reprocessing structures, as well as effective policy and regulation. To date, most academic and grey literature on the circular economy has focused primarily on the development of new business models, with some of the latter studies addressing design strategies for a circular economy, specifically in the area of resource cycles and design for product life extension. However, these studies primarily consider a limited spectrum of the technical and biological cycles where materials are recovered and restored and nutrients (e.g., materials, energy, water) are regenerated. This provides little guidance or clarity for designers wishing to design for new circular business models in practice. As such, this paper aims to address this gap by systematically analysing previous literature on Design for Sustainability (DfX) (e.g., design for resource conservation, design for slowing resource loops and whole systems design) and links these approaches to the current literature on circular business models. A conceptual framework is developed for circular economy design strategies. From this conceptual framework, recommendations are made to enable designers to fully consider the holistic implications for design within a circular economy

The circular economy: An interdisciplinary exploration of the concept and application in a global context

There have long been calls from industry for guidance in implementing strategies for sustainable development. The Circular Economy represents the most recent attempt to conceptualize the integration of economic activity and environmental wellbeing in a sustainable way. This set of ideas has been adopted by China as the basis of their economic development (included in both the 11th and the 12th ‘Five Year Plan’), escalating the concept in minds of western policymakers and NGOs. This paper traces the conceptualisations and origins of the Circular Economy, tracing its meanings, and exploring its antecedents in economics and ecology, and discusses how the Circular Economy has been operationalized in business and policy. The paper finds that while the Circular Economy places emphasis on the redesign of processes and cycling of materials, which may contribute to more sustainable business models, it also encapsulates tensions and limitations. These include an absence of the social dimension inherent in sustainable development that limits its ethical dimensions, and some unintended consequences. This leads us to propose a revised definition of the Circular Economy as “an economic model wherein planning, resourcing, procurement, production and reprocessing are designed and managed, as both process and output, to maximize ecosystem functioning and human well-being”

Circular Procurement: The First Step in a Series.

The Dutch Ministry of Infrastructure & Environment proudly hosted the first International Congress on Circular Procurement in Amsterdam on 20-22 April 2016. Attended by 120 experts from over 23 countries around the world, the Congress aims were to profile examples of Circular Procurement, to share experiences and to discuss how Procurement could be used as a powerful tool to deliver more circular economies.The Congress did not seek to define Circular Procurement but described it as the use of procurement as a mechanism to stimulate the circular economy by fulfilling the need for goods and services in a more circular, resource efficient way, by closing the loops of products, their components and the resources used as far as possible. Circular procurement therefore acts as a driver to help develop the circular economy by creating a demand for circular products. Collaboration, especially with the market, is an essential element in finding the best possible circular option available at the current time

Standardization Framework for Sustainability from Circular Economy 4.0

The circular economy (CE) is widely known as a way to implement and achieve sustainability, mainly due to its contribution towards the separation of biological and technical nutrients under cyclic industrial metabolism. The incorporation of the principles of the CE in the links of the value chain of the various sectors of the economy strives to ensure circularity, safety, and efficiency. The framework proposed is aligned with the goals of the 2030 Agenda for Sustainable Development regarding the orientation towards the mitigation and regeneration of the metabolic rift by considering a double perspective. Firstly, it strives to conceptualize the CE as a paradigm of sustainability. Its principles are established, and its techniques and tools are organized into two frameworks oriented towards causes (cradle to cradle) and effects (life cycle assessment), and these are structured under the three pillars of sustainability, for their projection within the proposed framework. Secondly, a framework is established to facilitate the implementation of the CE with the use of standards, which constitute the requirements, tools, and indicators to control each life cycle phase, and of key enabling technologies (KETs) that add circular value 4.0 to the socio-ecological transition

Sustainability principles through educational e-textile kit

Innovations in smart textiles technology are on the rise with a promise to add value to the consumer's life (Goodman et al., 2018). However, these innovations and the high development speed involved also raise concerns about environmental issues related to these trends (Van der Velden et al., 2015). Therefore, TTorch project was created which aim is to bring different fields, like electronics and textile engineering, together to create a kit for educational purposes and follow circular economy principles while doing it. TTorch is a creative toy with a development kit for up to 10-year-old children, using e-textile principles. The product kit creates a bridge between engineering and design, by letting the user explore a personal light source and build surroundings to it. The goal of the project is to show how interdisciplinary fields can work together and with that creating different opportunities. This paper gives a short overview of e-textiles, research on e-waste, textile waste and e-textile waste management. Further on it will focus on the necessary collaboration between design, engineering and industry by emphasising difference between core team and network around the core team. The collaboration aim it to create ecological product kit for educational purposes following the concept of STEAM. Discussions will include how collaboration between team members with diverse backgrounds, and surrounding network was necessary to identify specific gap in the market and to evolve the idea from product to development kit

Integrating Circularity in the Sustainability Assessment of Asphalt Mixtures

Rising concerns about the impacts that the road engineering industry is imposing to the environment have redirected national road authorities to firmly re-consider the sustainability implications of their operations. Lately, though, sustainability has established a forceful correlation with the Circular Economy and its principles. The road engineering industry, therefore, is moving towards more circular approaches. However, this is occurring without the assessment of the potential impacts of such a transition. For this reason, in this study, a composite indicator, namely, Environmental Sustainability and Circularity indicator (ESCi), for investigating the potential effects that increased circularity could have at the environmental sustainability of asphalt mixtures is developed. It can be utilized as a decision-making support tool from stakeholders involved in both asphalt mixture production and road pavement management. In addition, in this study, four asphalt mixtures with different percentages of Reclaimed Asphalt (RA) were assessed in terms of their “cradle-to-gate” environmental impacts and circularity, by means of Life Cycle Assessment, and Material Circularity Index, respectively. Their fatigue and permanent deformation performances play a key role in the assessment and distinctive results obtained for the asphalt mixtures with increasing RA% and thus, significant environmental benefits and increased circularity are observed after specific RA% threshold

Developing Scenarios for Product Longevity and Sufficiency

This paper explores the narrative of peoples’ relationships with products as a window on understanding the types of innovation that may inform a culture of sufficiency. The work forms part of the 'Business as Unusual: Designing Products with Consumers in the Loop' [BaU] project, funded as part of the UK EPSRC-ESRC RECODE network (RECODE, 2016) that aims to explore the potential of re-distributed manufacturing (RdM) in a context of sustainability. This element of the project employed interviews, mapping and workshops as methods to investigate the relationship between people and products across the product lifecycle. A focus on product longevity and specifically the people-product interactions is captured in conversations around product maintenance and repair. In exploring ideas of ‘broken’ we found different characteristics of, and motivations for, repair. Mapping these and other product-people interactions across the product lifecycle indicated where current activity is, who owns such activity (i.e. organisation or individual) and where gaps in interactions occur. These issues were explored further in a workshop which grouped participants to look at products from the perspective of one of four scenarios; each scenario represented either short or long product lifespans and different types of people engagement in the design process. The findings help give shape to new scenarios for designing sufficiency-based social models of material flows

The case for transforming the approach to waste, and growing a circular economy; a design perspective.

In recent years, there has been a growing discussion of resource efficiency, the ‘circular economy’ and the economic and environmental benefits of maximising the value of resources beyond the life of a product. This Environmental Audit Committee inquiry was initiated to examine the case for transforming the approach to waste, and growing a 'circular economy'. This is an evidence paper published online at http://www.publications.parliament.uk/pa/cm201415/cmselect/cmenvaud/214/21411.htm A full transcript of the inquiry is available at http://data.parliament.uk/writtenevidence/committeeevidence.svc/evidencedocument/environmental-audit-committee/growing-a-circular-economy/oral/9635.html
