As much as one-third of the food intentionally grown for human consumption is never consumed and is therefore wasted, with significant environmental, social and economic ramifications. An increasing number of publications in this area currently consider different aspects of this critical issue, and generally focus on proactive approaches to reduce food waste, or reactive solutions for more efficient waste management. In this context, this paper takes a holistic approach with the aim of achieving a better understanding of the different types of food waste, and using this knowledge to support informed decisions for more sustainable management of food waste. With this aim, existing food waste categorizations are reviewed and their usefulness are analysed. A systematic methodology to identify types of food waste through a nine-stage categorization is used in conjunction with a version of the waste hierarchy applied to food products. For each type of food waste characterized, a set of waste management alternatives are suggested in order to minimize environmental impacts and maximize social and economic benefits. This decision-support process is demonstrated for two case studies from the UK food manufacturing sector. As a result, types of food waste which could be managed in a more sustainable manner are identified and recommendations are given. The applicability of the categorisation process for industrial food waste management is discussed.

As nations develop policies for low-carbon transitions, conflicts with existing policies and planning tools are leading to competing demands for land and other resources. This raises fundamental questions over how multiple demands can best be managed. Taking the UK as an empirical example, this paper critiques current policies and practices to explore the interdependencies at the water-energy-food nexus. It considers how current land uses and related policies affect the UK’s resilience to climate change, setting out an agenda for research and practice relevant to stakeholders in land-use management, policy and modelling. Despite recent progress in recognising such nexus challenges, most UK land-related policies and associated science continue to be compartmentalised by both scale and sector and seldom acknowledge nexus interconnections. On a temporal level, the absence of an over-arching strategy leaves inter-generational trade-offs poorly considered. Given the system lock-in and the lengthy policy-making process, it is essential to develop alternative ways of providing dynamic, flexible, practical and scientifically robust decision support for policy-makers. A range of ecosystem services need to be valued and integrated into a resilient land-use strategy, including the introduction of non-monetary, physical-unit constraints on the use of particular services

Sustainable development is the current strategic trajectory with transformative intent for complex global challenges including eradication of poverty, full social inclusion and prevention of ecological collapse. However, discourses related to the private sector emphasise economic and social development over the environmental components of sustainable development. Embedding sustainability is the related management imperative for business, supported by numerous frameworks, yet there is confusion about implementation in both literature and practice. This research addresses these issues with a mixed methods study combining a scoping literature review with a qualitative e‐Delphi study. The main findings are that the economic system constrains the embedding of sustainability in business; and that a paradigm shift towards ecocentric business models lacks support. The results are used to develop a novel model to aid transformational sustainable development that acknowledges the influences of the economic system in business whilst respecting social and ecological embeddedness.

Recent trends in the bio-plastics industry indicate a rapid shift towards the use of bio-derived conventional plastics such as polyethylene (bio-PE). Whereas historically a significant driver for bio-plastics development has been their biodegradability, the adoption of plastics such as bio-PE is driven by the renewability of the raw materials from which they are produced. The production of these renewable resources requires the use of agricultural land, which is limited in its availability. Land is also an essential requirement for food production and is becoming increasingly important for fuel production. The research presented in this paper envisages a situation, in the year 2050, where all plastics and liquid fuels are produced from renewable resources. Through the development of different consumption and productivity scenarios, projected using current and historic data, the feasibility of meeting global demands for food, liquid fuels and plastics is investigated, based on total agricultural land availability. A range of results, comparing low-to-high consumption with low-to-high productivity, are reported. However, it is from the analysis of the mid-point scenario combinations, where consumption and productivity are both moderate, that the most significant conclusions can be drawn. It is clear that while bio-plastics offer attractive opportunities for the use of renewable materials, development activities to 2050 should continue to focus on the search for alternative feed stocks that do not compete with food production, and should prioritise the efficient use of materials through good design and effective end-of-life management.

The adoption of circularity indicators in the electrical and electronic sector is understood to play a critical role in organisational decision making during the transition from a linear to a circular economy. Yet, it is widely recognised that there is no standardised method of measuring circularity performance. Additionally, the extent of literature uncovers a range of shortcomings of existing cross-sector circularity indicators, including a predominant focus on end-of-life, limited coverage of social measurements, a lack of sector specificity and limited capture of product functionality, durability or sharing. Furthermore, the current electrical and electronic sector-specific circularity indicators focus greatly on repair and recycling, failing to acknowledge the significant impact on circularity of the design and manufacturing, distribution and use phases. Therefore, this research set out to answer how electrical and electronic manufacturers can measure the circular economy performance of their products by developing and testing multidimensional circularity indicators for all products’ life cycle stages. To achieve this, a two-fold qualitative approach was adopted. Firstly, a stakeholders’ workshop aiming to generate, categorise and rate novel circularity indicators was held. Secondly, a focus group piloted the resulting workshop’s circularity indicators. The findings highlight key factors that influence circularity indicators’ applicability to electrical and electronic products, including product function, service arrangement, and customer type. The research has implications for electrical and electronic organisations seeking pathways to the circular economy by understanding, assessing, and measuring the circularity of their products.

The growing interest in bio-polymers as a packaging material, particularly from companies looking to reduce their environmental footprint, has resulted in wider adoption. Traditionally the selection and specification of packaging materials was based on aesthetic, technical and financial factors, for which established metrics exist. However with bio-polymers, where the primary rationale for their use is environmental, alternative metrics are required. Furthermore, there is a significant strategic element to the decision process that requires a broader range of horizontal and vertical inputs, both within the business and the wider supply chain. It is therefore essential that a holistic approach is taken to the bio-polymer based packaging design process to ensure that the final packaging meets the original strategic intent and overall requirements of the business. Current eco-packaging design tools are generally limited to professional users, such as designers or packaging engineers, and generally provide tactical rather than strategic support. This disconnect, between the need for inclusivity and greater strategic support in holistic design, and the exclusivity and largely tactical support of current eco-design support tools, indicates a clear need for a new decision support tool for sustainable pack design using bio-polymers. This paper proposes a framework for an eco-design decision support tool for bio-polymer based packaging that has been developed using a predominantly qualitative research approach based on reviews, interviews and industrial packaging design experience and is an extension of previously published work. This research investigates further how existing eco-design methods, such as the ‘Balanced Score Card’, can be applied within the tool and how the shortcomings associated with incorporating social and environmental aspects can be partly resolved, through a simplified set of metrics tailored specifically for bio-polymer packaging decisions. The results of this research is a framework for the development of a three tier eco-design tool for bio-polymer packaging that provides decision support at the three critical stages of the design process: strategic fit, Feasibility assessment and concept/pack development.
