Abstract [en]

Synthetic diamond competes with the conventional cemented carbide (WC–Co) tool material in some applications due to its extreme hardness. However, so far, these materials have not been compared from a life cycle perspective regarding their environmental and resource impacts. The aims of this study are i) to provide detailed life cycle assessment (LCA) results for industrial polycrystalline diamond (PCD) production from diamond grit produced via high-pressure high-temperature (HPHT) synthesis and ii) to conduct the first comparative LCA of PCD and WC-Co tools for the cases of wood working and titanium alloys machining. The results show that the main hotspot in HPHT synthesis of diamond grit, which is the main precursor to PCD, is the use of WC-Co in the high-pressure apparatus. In PCD tool production, the electricity input and the use of tungsten and molybdenum contribute the most to environmental and resource impacts. The environmental and resource impacts of the PCD tool production can be reduced with 53–83% if solar electricity and full WC-Co recycling is applied. The comparison shows high environmental and resource improvements when substituting WC-Co tools with PCD tools in wood working, but not in titanium alloys machining. © 2020 The Authors

Abstract [en]

Investigations of metal ecotoxicity in life cycle assessment (LCA) and life cycle impact assessment (LCIA) are becoming important tools for evaluating the environmental impact of a product or process. There is, however, improvement needed for LCIA of metal ecotoxicity in order to make this assessment more relevant and robust. In this work, three issues within the LCIA of metal ecotoxicity are investigated, mainly focusing on topics related to stainless steel manufacturing. The first issue is the importance of considering regional water chemistry when constructing the characterization factor (CF). A model freshwater of relevance for stainless steel manufacturing in a region of Sweden was created with chemistry different from available options. The second issue is related to the lack of consideration on changes in speciation of Cr(VI) in freshwater for a given emission, as Cr(VI) to some extent will be reduced to Cr(III). Two new options are suggested based on relationships between the Cr(VI)-total Cr ratio as a way to improve the relevancy of LCIA for Cr(VI) in freshwater. The last issue is how to treat metal release from slags in LCIA. Metal release from slags was shown to vary significantly between different ways of modelling slag emissions (differences in total metal content, slag leaching tests, estimated emissions to groundwater). © 2019 by the authors.

Abstract [en]

Lithium-air batteries are investigated for propulsion aggregates in vehicles as they theoretically offer at least 10 times better energy density than the best battery technology (lithium-ion) of today. A possible input to guide development is expected from Life Cycle Assessment (LCA) of the manufacture, use and recycling of the lithium-air battery. For this purpose, lithium-air cells are analyzed from cradle to grave, i.e., from raw material production, cathode manufacturing, electrolyte preparation, cell assembly, use in a typical vehicle to end-of-life treatment and recycling. The aim of this investigation is highlighting environmental hotspots of lithium-air batteries to facilitate their improvement, in addition to scrutinizing anticipated environmental benefits compared to other battery technologies. Life cycle impacts are quantified in terms of climate impact, abiotic resource depletion and toxicity. Data is partly based on assumptions and estimates guided from similar materials and processes common to lithium-ion technologies. Laboratory scale results for lithium-air systems are considered, which include expectations in their future development for efficiency gains. At the present level of lithium-air cell performance, production-related impacts dominate all environmental impact categories. However, as the performance of the lithium-air cell develops (and less cells are needed), battery-related losses during operation become the major source of environmental impacts. The battery internal electricity losses become heat that may need considerable amounts of additional energy for its transportation out of the battery. It is recommended that future battery cell development projects already at the design stage consider suitable methods and processes for efficient and environmentally benign cell-level recycling. LCA could provide additional arguments and a quantitative basis for lithium battery recycling. This emphasizes the need to develop LCA toxicity impact methods in order to properly assess lithium.

Abstract [sv]

Hållbar utveckling innefattar såväl social, ekonomisk som miljömässig hållbar utveckling.

I Miljöhandboken kommer dessa tre aspekter av hållbar utveckling att behandlas,

dock ligger störst fokus på miljöaspekterna.

Miljöhandboken ska hjälpa upphandlare att ställa relevanta miljökrav vid upphandling

och är ett komplement till exempelvis Konkurrensverkets (f.d. Miljöstyrningsrådets)

upphandlingskriterier och ska bidra med fakta kring hur miljökrav kan ställas.

Miljökrav vid upphandling kan innefatta bl. a. energianvändning, livslängd, skadliga

ämnen, strålning, återvinning och miljöledningssystem. Kravens betydelse påverkas

bl. a. av upphandlingens omfattning och miljömognaden inom produktsegmentet. I

miljöhandboken presenteras inga specifika kriterier eller gränsvärden för olika miljöaspekter,

i stället ges länkar till exempelvis lagstiftning, myndigheter och miljömärkningar.

Detta för att kriterier och gränsvärden uppdateras kontinuerligt som en följd

av teknikutveckling men också för att den samlade kunskapen om vad som är miljöproblem

ständigt växer och kan ge upphov till nya kriterier och gränsvärden. Tyngdpunkten

i denna handbok ligger på miljöpåverkan ur ett livscykelperspektiv, vilket innebär

att hänsyn tas till miljöpåverkan från utvinning av råmaterial till resthantering av

en produkt.

Abstract [sv]

Mall för miljöutredning hjälper dig att samla in och redovisa kvantitativa data om material- och energiflödet genom det egna företaget. Med hjälp av dessa data skapas en bild som beskriver miljöpåverkan av företagets verksamhet och produkter i ett livscykelperspektiv.

Till skriften hör bland annat:

• en Wordmall för miljöutredningen, där man fyller i tabeller och justerar texten

• ett inventerings- och beräkningsverktyg i Excel, som räknar ut miljöpåverkan av företagets transporter, material, utsläpp och energi

• en översikt av miljölagarna för inventering av lagkrav

• instruktioner och blanketter för Miljö-FMEA; ett sätt att identifiera och värdera miljöpåverkan.
