A collaborative UK government-funded research project drawing on the design and sustainability expertise of the Department of Design and Technology at Loughborough University and the sustainability and product bank functions at The Boots Company set out to investigate the potential that refi llable packaging systems can offer the consumer and the environment. In the past, refi lls have generally been categorized under one general heading and often branded as a failure. However, early in the project, the team identifi ed that by taking a creative approach to interpreting refi lls, there are actually a wide range of different types of refi lls that can be differentiated with respect to their delivery approach and level of consumer/business interaction. Once these had been identifi ed, collated and categorized, the team set out to investigate the consumer perceptions, and the business barriers and drivers found to infl uence the adoption and success of a number of different types of refi llable packaging. This paper reports on those fi ndings. It concludes that differentiating between refi ll types holds the key to developing more suitable and more successful refi llable packaging systems as positive and negative attributes can be more accurately identifi ed and responded to.

a b s t r a c tHigher Education Institutions play a critical role in societies transition towards sustainable development, educating future professionals and decision makers. In the last few decades, a number of technical universities have devoted major efforts to integrating sustainable development into engineering curricula. There is still, however, an increasing need to further transform learning and training environments and build capacity of educators and trainers on sustainable development issues.Against this background, this paper assesses the role of online training courses, within continuing professional development strategies, in promoting sustainable human development in engineering degrees. It was built upon the implementation of a European initiative, the Global Dimension in Engineering Education, promoted by a transdisciplinary consortium of technical universities and nongovernmental organisations.In terms of method, this study analyses two sets of quantitative and qualitative indicators to assess i) the perceived quality/relevance of the training proposals, and ii) the learning acquisition of participants. Quantitative indicators were complemented by a descriptive analysis of findings from a semi-structured survey. The results provide evidence that online learning can be an effective approach for continuing professional development of academics. The findings also suggest that participants perceived online courses' contents and curricula, developed jointly by academics and practitioners of non-governmental organisations, as relevant and useful for integrating sustainability principles in teaching activities. To conclude, authors recommend the leaders of higher educational institutions to explore the integration of online courses addressed to faculty into university policy and strategies, as a way to promote professional development and the engagement of academics on sustainable development.

• This is the peer reviewed version of the following article: LOFT- A broad range of qualitative methods were used to create a background framework, develop design concepts and test the viability of the design solutions. Two concepts were turned into high fidelity prototypes and tested in multi-activity user focus groups. The prototypes were evaluated from an environmental perspective using the Eco Indicator 99.Discussion is focused around general findings regarding refillable packing and also on specific findings related to 'concentrates mixed in the parent pack'. The findings from this study have increased understanding about the potential implications of refillable packaging and how it might be successfully utilised by business. A range of guidelines for the design of refills have been identified. Further a more detailed understanding of consumer perceptions, business challenges/opportunities and environmental savings associated with 'concentrated refills that are mixed in the parent pack', has been identified.It has been seen that to be successful refills must offer good quality; be very easy to use and appropriately delivered; be clearly communicated; be offered through a brand consumers like; and represent good value, whilst radically reducing the amount of packaging manufactured and distributed. Incorporating carefully considered consumer and environmental needs into the brief is critical to the successful development of refillable packaging.

This study set out to better understand the feelings of stakeholders from the UK food packaging supply chain towards a move to circular economy (CE) systems. The research areas studied included current and future challenges facing supply chain stakeholders, the consideration of transformative technologies (TT) to enable packaging solutions in the move to CE systems and what CE systems using TT would look like for the UK's chilled food packaging sector. A questionnaire was selected to obtain data from across the UK food packaging supply chain. Participants were selected from six industry stakeholder groups, with 24 completing the questionnaire. This study has clearly shown there is a large spectrum of solutions in a move to CE, each with their own benefits and limitations. TT has an ability to enable these, but in selecting the best one for a specific packaging solution, a decision maker must take into consideration business constraints of the supply chain and the consumer's behaviour towards new solutions.

The growth of eating lunch purchased out of the home has led to an increased need for pre-packaged food-to-go products. Single-use plastic packaging is frequently chosen for its food safety and convenience attributes; however, the material format is under scrutiny due to concerns over economic waste and environmental impact. A circular economy could transform linear make-use-dispose supply chains into circular systems, ensuring the cycling of valuable plastic resources. However, there has been limited research into how consumers will behave within circular economic systems. Understanding consumer behaviour with packaging disposed out of the home could aid designers in developing solutions society will adopt in the transition to a circular economy. This study evaluates the application of behaviour research methods, and the behavioural insight outputs, with stakeholders from the UK food-to-go packaging supply chain. A novel co-design workshop and business origami technique allowed multiple stakeholder groups to collaboratively discuss, evaluate, and plan how consumer behaviour techniques could be used within their supply chain packaging development process. Although all stakeholders identified strengths in incorporating behaviour studies into the development process, providing essential knowledge feedback loops, barriers to their application include the cost and time to implement, plus the existing inconsistent UK waste infrastructure.
