Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The article entitled ‘Review: the availability of life-cycle studies in Sweden’ by Croft and colleagues (January 2019, volume 24, issue 1, pages 6–11) has puzzled many researchers in Sweden. The stated purpose of the article is to review the availability of water and carbon footprinting studies and life-cycle assessment (LCA) studies in Sweden. Despite its title and purpose suggesting otherwise, the article appears to be about the accessibility of life-cycle case studies from Sweden in South Africa. It is problematic that the article claims to be a review in the title and text, but is presented by the journal as a commentary. We believe that the article’s method is unclear and that its title and results are misleading. The authors of the article found only 12 academic papers, 10 academic theses, 8 company reports, and 1 presentation. This result significantly underestimates the actual production and availability of Swedish LCA case studies.

- A greater quantity and variety of materials are being produced worldwide to meet demand for consumer products, buildings and infrastructure. Additionally, highly diffused products such as cars and electronics have become materially complex and depend on numerous scarce metals. Consequently, managing the societal supply of a variety of materials and metals sustainably is becoming increasingly important. This includes the use of efficient and effective waste management. However, the current management of waste in general and of waste consumer products specifically, have been pointed out as requiring significant developments to become more advanced to cope with the increasing material complexity. It has also been pointed out that research taking systems perspectives is crucial to improve waste management. Additionally, researching change processes and the co-evolution of social and technical factors (i.e., socio-technical change), has furthered the understanding of how ‘green’ industries develop in other empirical fields. Consequently, both systemic and socio-technical perspectives are likely relevant to waste management research. We used the Scopus database to search for 31 research approaches associated with such perspectives in journal articles writing about waste management in general, waste electrical and electronic equipment (WEEE) or end-of-life vehicles (ELVs). We conclude that, although the majority of the examined research does not mention the considered approaches, some environmental system analysis approaches are frequently mentioned and show signs of growth in adoption. In contrast, socio-technical approaches are scarcely mentioned. Consequently, we argue that there are relevant scientific tools yet to be adopted in waste management, WEEE and ELV research.

- Improved recycling of end-of-life vehicles (ELVs) may serve as an important strategy to address resource security risks related to increased global demand for scarce metals. However, in-depth knowledge of the magnitude and fate of such metals entering ELV recycling is lacking. This paper quantifies input of 25 scarce metals to Swedish ELV recycling, and estimates the extent to which they are recycled to material streams where their metal properties are utilised, i.e. are functionally recycled. Methodologically, scarce metals are mapped to main types of applications within newly produced Swedish car models and subsequently, material flow analysis of ELV waste streams is used as basis for identifying pathways of these applications and assessing whether contained metals are functionally recycled. Results indicate that, of the scarce metals, only platinum may be functionally recycled in its main application. Cobalt, gold, manganese, molybdenum, palladium, rhodium and silver may be functionally recycled depending on application and pathways taken. For remaining 17 metals, functional recycling is absent. Consequently, despite high overall ELV recycling rates of materials in general, there is considerable risk of losing ELV scarce metals to carrier metals, construction materials, backfilling materials and landfills. Given differences in the application of metals and identified pathways, prospects for increasing functional recycling are discussed.

Tidskriftsartikel (refereegranskat)abstract
- Cars and electronic products are characterised by high metal complexity. Meanwhile, recycling industries are not fully aligned with this complexity, leading to losses of unique scarce metal resources. By utilising the technological innovation system framework we identify, and discuss implications of, factors that impact on recycling of some precious (gold, palladium, silver) and minor metals (gallium, tantalum) in printed circuit boards (PCBs) present in Swedish end-of-life cars (ELVs) and waste electrical and electronic equipment (WEEE). We conclude that while precious metals from WEEE PCBs are currently recycled, recycling precious metals from ELV PCBs will likely remain a challenge in the near-term due to recycling being blocked by the material composition of ELV waste, design of waste legislation, and by accumulated capabilities and business models in current recycling industries. However, some of these blocking factors are open to direct influence from national policymakers or industry actors and may thus be alleviated more easily. In contrast, recycling minor metals from ELV or WEEE PCBs will likely remain challenging also in the long-term due to a larger set of blocking factors. Alleviating these may require a substantial portfolio of metal-specific policies at national and supra national levels supporting the build-up of entirely new recycling value chains.

- End-of-Life Vehicles (ELVs) contain materials that may be beneficial to recycle. While metals such as iron, aluminium and platinum are recycled at high rates, materials such plastics and most scarce metals are recycled at low rates or not at all. Insight into how recycling systems form and develop is limited in current research, but may provide a better understanding for how to increase recycling rates. This paper utilises the technological innovation system framework to identify key functions from 1910 to 2010 that enabled ELV iron recycling in Sweden. Initiatives for improving capabilities to recycle other materials are also discussed. Results indicate that early structural changes in the steel industry were crucial. Subsequently, ELV iron could be utilised by this industry through build-up of an increasingly specialised ELV system. We argue that reproducing the key functions that enabled ELV iron recycling may serve to increase recycling rates also of other ELV materials.

Mapping the content and fates of scarce metals in discarded cars

Konferensbidrag (refereegranskat)abstract
- A great variety of current products make use of components or materials (e.g. electronics, steel and aluminium alloys) that utilise increasing amounts of ‘critical’ or scarce metals (SM). For example, design trends for cars point at increasing SM utilisation in order for regulatory, business and consumer requirements on environmental performance, safety, costs, comfort and infotainment to be met. Modern cars now hold SM in substantial amounts, i.e. the circa one billion cars in use worldwide today, constitute a significant near-term secondary SM resource. However, current end-of-life vehicle (ELV) recycling is mainly aimed at isolating hazardous contents, dismantling spare parts and recycling bulk metals. There is thus a clear risk that ELV SM are not functionally recycled and thus lost for further use.Assessments of the opportunities for increased functional recycling require estimates of SM content of discarded cars and individual waste flows in ELV recycling. However, information on both is limited. Data related to cars is sparse, and challenged by the large range and age span of discarded car brands and models. Measurements of SM in waste flows are few and cover a limited range of SM. Consequently, available data does not allow us to quantify with precision the SM contents of discarded cars reaching the ELV recycling system, or map individual metal flows within it.Instead, our approach relies on mapping 25 ELV SM to main types of applications within three newly produced car models using automotive industry data (International Material Data System, IMDS), and letting these models represent the ELV fleet so that the annual input magnitudes of SM to ELV management can be estimated. Subsequently, we employ material flow analysis of ELV waste streams as basis for identifying potential pathways of these main applications, and the extent to which contained metals may reach processes capable of functional recycling. The approach allows us to qualitatively distinguish subsets of systems flows holding groups of SM, and discuss the potential for functional recycling.Using Swedish ELV management as a case, we conclude that only platinum may be functionally recycled in its main application. Cobalt, gold, manganese, molybdenum, palladium, rhodium and silver may be functionally recycled depending on application and pathways taken. For remaining 17 metals, functional recycling is lacking. Consequently, there is considerable risk of losing SM with current ELV procedures. Given differences in the application of metals and identified pathways, strategies for improving recycling and resource security are considered. Moreover, our case illustrates the considerable challenge, posed by the complexity and range of car configurations and the sparsity of information on SM, to closer assess recycling strategies and advance secondary SM resource utilisation.
