Every year, tens of millions of the 1.4 billion cars on the world’s roads are decommissioned. While the ferrous and other metals that constitute about 75% of a vehicle by weight can be readily and profitably recycled, the remaining mix of plastics, glass, composites, complex materials, fragments and contaminants are mainly destined for landfill as automotive shredder residue (ASR). For every car, approximately 100–200 kg of ASR is disposed of in landfill, posing a growing technical and environmental challenge worldwide. The recovery of the ASR for high-end application is the focus of this study, aiming to optimise the use of these valuable resources and minimise the extractive pressure for raw materials, a future green manufacturing, contributing towards a zero waste circular economy. As the dissolution of carbon into iron is a key step in the manufacture of iron-carbon alloys, the feasibility of utilizing the waste polymers within ASR as sources of carbon in different areas of pyrometallurgical processing was investigated. Polypropylene and rubber, in a blend with metallurgical coke, were used as carbonaceous substrates and the slag-foaming phenomenon was investigated via the sessile drop technique in an argon environment at 1,550°C. The results indicated the rubber/coke blend achieved significantly better foaming behaviour, and the PP/coke blend exhibited a moderate improvement in slag foaming, in comparison to 100% metallurgical coke. The overall results indicated the incorporation of ASR had significant improvement in foaminess behaviour, increasing furnace efficiency.

Much of the body of literature analysing the gig economy focuses on its exploitation of low-wage workers and its role in increasing precarious work. This chapter approaches the topic from a different angle, focussing on the contribution of the gig economy to the declining power of the medical profession. As well as facilitating and promulgating contingent work in healthcare, the gig economy disaggregates medical work into isolated on-demand micro-tasks on digital platforms. This has implications for the status and power of the medical profession, the doctor–patient relationship, and inter-professional boundaries in healthcare. The mechanisms through which these dynamics unfold, as well as the inter-related factors that support the transformations in the allocation and content of medical work, are discussed. These include the implications of heightened transparency of medical work resulting from unbundling of jobs, commodification of medical professionals, and platform-based vulnerabilities such as rating systems that impact doctor–patient relationships. Closure theory is drawn on to illuminate the dynamics of the transformation in professional boundaries and the arising conflict that it entails for the healthcare workforce at different levels. The conflict is theorised as an insidious exercise of closure by allied health professionals on the remit of the medical profession, which challenges remuneration, authority, and other exclusionary benefits traditionally accrued to the medical profession.

In most classrooms, where information is presented orally via spoken language, accurate knowledge of a student’s hearing status is crucial so that the interdisciplinary team can ensure appropriate service provision. Audiologists play a key role on the interdisciplinary team to provide other professionals with information about children’s hearing status, communication needs, device use, and intervention strategies. Conversely, audiologists gain valuable information and strategies from other team members.

In 2018, significant legislative changes were made in child welfare in Ontario, Canada. As part of the changes, a Voluntary Youth Services Agreement was developed to allow young people between 16 and 17 years of age to obtain the necessary support services that they need to be able to further their independence, autonomy and agency in their lives. Yet, hearing directly from young people about the benefits and challenges of this program is limited. This study was intended to address these gaps. There were 15 young people (11 females and four males) who participated in a telephone interview about their views and experiences with the VYSA agreements. The majority spoke positively about the benefits of the programme and being able to continue their schooling, purchase clothing and obtain employment. They also believed that the programme allowed them more security and safety than being homeless. Some raised the challenges related to the amount of money that they received should be determined by the place that they reside in as some cities are more expensive than others. From a policy perspective, as the program continues, further changes may also be explored that examines the eligibility criteria where young people must be in need of protection before they can enter the program. In other words, moving from a deficit-based approach to a more child centred practice that includes hearing from young people in child welfare.
