Plastic waste derived from the packaging industry currently represents an important environmental problem. Therefore, it is necessary for product designers and engineers to become aware of this fact and seek to incorporate the environmental vector when designing, redesigning, and developing containers and packaging, so that they are more sustainable and eco-effectiveness. Starting from this premise, the following objectives have been proposed in this work: (1) study and identification of possible Ecodesign strategies to apply to an existing agricultural package (model used in the collection and distribution of fruit and vegetable products); (2) to propose a redesign of the package studied, applying the information and knowledge obtained previously; (3) comparative analysis between the existing (commercial) package and the redesign proposal developed. In order to respond to this approach, work has been carried out with CAD/CAE tools (SolidWorks 3D CADTM software). The results obtained from the case study developed in this work indicate that the application of CAD/CAE tools supported by the proposed Ecodesign strategies can be a very useful and effective instrument in the design and development of this type of packaging, for practical application in the agro-food and packaging industry, which can facilitate in the short to medium term the transition to a circular economy model, based on the "Cradle to Cradle" concept.

Finite Planning Horizon

Abstract This paper describes the optimization of preventive maintenance (PM) over a finite planning horizon in a semi-Markov framework. In this framework, the asset may be operating, and providing income for the asset owner, or not operating and undergoing PM, or not operating and undergoing corrective maintenance following failure. PM is triggered when the asset has been operating for τ time units. A number m of transitions specifies the finite horizon. This system is described with a set of recurrence relations, and their z-transform is used to determine the value of τ that maximizes the average accumulated reward over the horizon. We study under what conditions a solution can be found, and for those specific cases the solution τ* is calculated. Despite the complexity of the mathematical solution, the result obtained allows the analyst to provide a quick and easy-to-use tool for practical application in many real-world cases. To demonstrate this, the method has been implemented for a case study, and its accuracy and practical implementation were tested using Monte Carlo simulation and direct calculation.

Conservation Actions

AbstractConservation practices during the first decade of the millennium predominantly focused on resisting changes and maintaining historical or current conditions, but ever-increasing impacts from climate change have highlighted the need for transformative action. However, little empirical evidence exists on what kinds of conservation actions aimed specifically at climate change adaptation are being implemented in practice, let alone how transformative these actions are. In response, we propose and trial a novel typology—the R–R–T scale, which improves on existing concepts of Resistance, Resilience, and Transformation—that enables the practical application of contested terms and the empirical assessment of whether and to what extent a shift toward transformative action is occurring. When applying the R–R–T scale to a case study of 104 adaptation projects funded since 2011, we find a trend towards transformation that varies across ecosystems. Our results reveal that perceptions about the acceptance of novel interventions in principle are beginning to be expressed in practice.

AbstractThis paper discusses the uses and applications of the Pedagogy of Experience Complexity for Smart Learning (PECSL), a four-tier model of considerations for the design and development of smart learning activities. Using existing mobile apps and relevant activities as illustrative examples, the PECSL is applied to indicate concepts and mechanisms by which useful pedagogical considerations can work alongside user-centred design principles for the design and development of smart learning in urban hyper-localities. Practical application of the model is discussed using real world examples of activities as a basis to demonstrate the potential for manifold opportunities to learn, and plan for experience complexity in a smart learning activity. Case study approaches reflect on aspects of the PECSL in how it might be a useful and pragmatic guide to some of the issues faced when designing digital citizen learning activities in complex urban environments.

Practical Implications

Purpose International attention is increasingly turning to the challenge of creating age-friendly environments. This study aims to examine the application of asset-based approaches in undertaking community development projects with older people. The paper intends to share the learning that may be useful when designing community development projects for older people in the future. Design/methodology/approach This study followed a multiple project case study design, with a focus on project delivery practices. It was undertaken as a co-production exercise involving university researchers and trained older volunteer community researchers (CRs). Over 18–24 months of qualitative research was conducted in relation to six area-based urban projects between 2018 and 2020. Findings There were five leading themes as follows: mapping and building on assets in highly localised settings; creating governance and direction through steering groups; developing activities with diverse groups of older people; reaching isolated and lonely older people; building local capacity to embed sustainability. Practical implications The effectiveness of assets-based approaches in promoting age-friendly agendas appears to be contingent on the values, skills, capacity and resourcing of delivery agencies, alongside wider public sector investment in communities. Diversity and inequalities amongst older people need to be taken into account and community development that specifically focuses on older people needs to be balanced with the whole population and intergenerational practice. Originality/value This paper provides an empirical account of the practical application of assets practices specifically in the context of the age-friendly community agenda. The co-production method brings together insights from academic and volunteer older CRs.
