Assessing toxicity of metals in life cycle assessment, MINTox

Reference number
Coordinator RISE IVF AB - Swerea IVF AB, Mölndal
Funding from Vinnova SEK 2 290 000
Project duration August 2016 - August 2019
Status Completed

Purpose and goal

The aim of the project was to improve the possibilities of assessing the environmental impact of metals from a life cycle perspective. By more accurate assessment, the goal was to be able to show benefits of Scandinavian steel production. Particular focus has been on improving methodology for assessing toxicity of metals in life cycle assessment. The project has resulted in improved methodology, which takes into account bioavailability, chromium speciation, and water chemistry. In addition, deficiencies in database data were noted.

Expected results and effects

Through this project, industry knowledge has increased in a number of areas regarding environmental impact of metals. The importance of good slag management and reduction of metal emissions from processes has been discussed with Scandinavian steel producers. Knowledge of chromium specification, bioavailability and recipient´s water chemistry has been raised. This knowledge gives the industry the opportunity to further work towards reduced environmental impact. In discussions with the EU-Commission, the importance of this has been highlighted in relation to ongoing PEF work.

Planned approach and implementation

The project has been carried out through field studies, laboratory studies, modeling and review of databases in order to study the chemical form and bioavailability of metals for various exposure scenarios of relevance to industrial partners. This has been done in collaboration between KTH, RISE IVF and steel producing companies. During the project, information was shared with other actors such as industry organizations, institutes and the EU-Commission. In order to achieve goals regarding dissemination of knowledge, project members have presented results in different forums.

The project description has been provided by the project members themselves and the text has not been looked at by our editors.
