This paper examines employees' work-related attitudes to recycling and waste management systems whilst retaining a link with personal domestic behavior. A questionnaire of 38 Likert-type items measured employee attitudes to environmental, waste management and recycling, environmental and sustainability concerns, perceived costs and benefits to the company. The hypotheses included demographic differences in attitudes, that attitudes and behavior are related and that behaviors transfer from home to work. The sample included 189 employees from 6 northern UK companies. A factor analysis reduced the attitudes items into four factors, being a positive approach to company recycling, that policies are needed, that recycling is costly to the company and that recycling can earn money. The factors were correlated with behavioral measures and compared by demographics and past recycling behavior using t-tests and ANOVAs. The results show differences in attitudes and behaviors by job type and age, that recycling at work and home are unrelated but that use of eco-friendly products is related to attitudes and concern about depletion of natural resources. The findings are discussed in terms of attitude theories, workplace behavior, training and communications about environmental and waste management in companies plus the transferability of these findings to other types of management systems, other sectors or regions.

Many cities publish climate change mitigation strategies and other policy measures to support the wide spread uptake of Electric Vehicles (EVs). This paper investigates the effectiveness of these strategies and the provision of infrastructures in 30 UK cities, with a specific emphasis on those strategies that are within the remit of cities and local authorities. The climate mitigation strategies and supporting documents were obtained from 30 UK cities recommended by the Urban Audit Methodology. We show that 13 cities mention EVs in their strategies. Analysing EV registrations and the EV infrastructures that is provided by cities we found that there is no statistical difference in the number of charging points or EVs between the cities that have EVs as part of their climate change mitigation strategy and those that do not. It was shown that EV uptake was more generally associated with other factors (such as local vehicle population or income) rather than any documented EV/climate mitigation strategy. We demonstrate that local strategies are failing in achieving the much needed step change and make suggestions how to improve EV uptake as an even more radical thinking and policies may become necessary to achieve carbon reduction targets.

• The present paper provides a short review on the basics of the supply and value chain challenges for EV batteries. • The paper serves as the editorial for a special issue on sustainable supply and value chains of EV batteries. • The state-of-the-art and gaps in EV LIBs research and development are presented with regards to five main themes. Lithium-ion batteries (LIBs) play a key role in advancing electromobility. With an increasing trend in the demand for LIBs, the sustainability prospect of LIBs lifecycle faces many challenges that require proactive approaches. There are various sustainability challenges and risks across the supply and value chains of LIBs from mining, material supplies to Original Equipment Manufacturers (OEMs), users to final disposal. Risks are for example the increased raw material demands as well as some economic risks due to price increment or political instabilities in some countries within the raw material supply chain. Despite the promising research efforts on the performance metrics of LIBs and advancing the technology, the research on the various aspects of sustainability of LIBs and its life cycle are still in its infancy and require closer attention. As the editorial of the Special Issue on sustainable supply and value chains of EV batteries, this article presents some of the most pressing challenges of EV LIBs across the different stages of its life cycle. It covers issues from supply and demand of the battery raw materials, battery manufacturing, use, and end-of-life treatments. Within this context the reported findings of some 20 different research teams from across the globe, the state-of-the-art, technical or policy gaps in EV LIBs research and development are presented, as well as market instruments such as innovative business models, and governmental interventions like subsidies or regulations. We grouped the materials presented into five main themes (1) EV and LIB materials demand projections (2) EV LIBs international trade risk (3) EV battery regulation and adoption (4) EV LIBs life cycle assessment (5) and EV LIBs reverse logistics. We conclude by discussing some future research challenges such as the need for more reliable and applicable prediction models that use accurate data on EV stock and end-of-life EVs. Finally, we argue that more collaboration between academia, manufactures, OEMs and the battery recycling industry is needed to implement successful circular economy strategies to achieve environmentally friendly, flexible and cost-efficient battery supplies, use and recycling processes.

Abstract: The management of plastic wastes is important owing to the high levels of embodied fossil fuel energy they contain. Although the environmental benefits of closed-loop recycling of plastics have been established through a number of life cycle studies, the benefits of open-loop recycling of plastics have not been examined for many substituted materials. This paper compares two equivalent sports-field drainage systems, one based on conventional sand and aggregate drainage materials, the other incorporating a novel drainage material produced from mixed plastics waste. The scope is confined to an analysis of primary energy consumption and global warming potential. It was found that the novel drainage system had lower global warming potential and primary energy consumption than the conventional system. These results were robust to sensitivity analyses of electricity mix and transportation distance to installation. [ABSTRACT FROM AUTHOR]

The construction and maintenance of UK roads consume large amounts of quarried aggregates. The use of secondary (recycled), instead of primary (virgin), materials helps easing landfill pressures and reducing demand of extraction. However, concerns over inferior road performance and additional costs have hindered the widespread use of secondary aggregates in such applications. This is especially the case in surface layers of asphalt pavements that may represent a value application for recycled solid waste materials (SWM). Waste glass, steel slag, tyres and plastics are selected for this study, which reviews standards and literature for technical requirements, as well as the performance of asphalt pavements constructed using such recycled materials. Waste arising and management indicates that although there is a large potential for supplying secondary materials, a few factors have effectively depressed such recycling activities. Such barriers are described here and may also apply to the secondary use of other SWM. After identifying and quantifying such barriers a brief discussion suggests ways of their removal.

With the widespread adoption of e-mobility, there are high numbers of lithium Ion batteries (LIB) entering the waste stream. It is imperative that disposal and recycling strategies are developed and implemented. There is an urgent need for safe, environmentally friendly and economically affordable disposal routes for End of Life (EoL) LIBs. This study has looked at 44 commercial recyclers and assessed their recycling and reclamation processes. A novel qualitative assessment matrix termed "Strategic materials Weighting And Value Evaluation" (SWAVE) is proposed and used to compare the strategic importance and value of various materials in EoL LIBs. The sustainability and quality of recycled material are assessed by comparing the final form or composition after the recycling processes, the industrial processes and the industry type (primary sector, manufacturer or recycler). SWAVE is applied to each company, producing a score out of 20, with a higher number indicating that more materials can be recycled. The separation processes and resources from six of the prominent recycling companies are discussed further. The majority of recyclers use one or more of mechanical treatment, pyrometallurgy, or hydrometallurgy, concentrating upon high value metal extraction rather than closed-loop recycling of the metals or component materials, highlighting an environmental and technological gap. To improve the current circular economy of batteries reuse and repurposing of materials (closed-loop recycling), instead of purely recycling or recovery of metals should be considered for further development. Further studies of environmental trade-offs from recycling or recovering one material in preference to another is required. [ABSTRACT FROM AUTHOR]
