Mikroplast från däck- och vägslitage: en kunskapssammanställning


This literature review concerns microplastics from tyre and road wear caused by road traffic. As there is limited knowledge about microplastics in general, and microplastics from road traffic in particular, the Swedish Government has asked the Swedish National Road and Transport Research Institute (VTI) to, during 2018-2020, develop and disseminate knowledge about microplastics from road traffic. The chapters in this report summarises existing knowledge about microplastics from road traffic with respect to the following aspects: sources, spread and occurrence; effects on and risk to the environment and human health; characteristics and chemical composition; tyre and road wear; sampling methods; analysis and sample preparation; measures. The report also includes a chapter with overall conclusions, and a chapter about further research, development and investigation needs.

The purpose of this report is to provide a basis for reducing the generation and spread of microplastics from road traffic. One aim of the report is to collate and disseminate knowledge about microplastics generated by tyre and road wear, and to review the current level of knowledge. A second aim is to identify knowledge gaps and research requirements in relation to microplastics from road traffic. This literature review is based on a review of scientific articles and reports, as well as technical literature and some information from experts and industry.

Additional policy instruments are needed to achieve Swedish environmental quality objectives for maritime transport

Achieving the national and international environmental objectives for maritime airborne emissions requires a combination of new and more powerful policy instruments. The policies already in place are not enough. This is one of the conclusions of a research...


Opportunities for a new market in electrified regional flight

Large, electrified aircraft is far off in the future. On the other hand, there may be potential for a new market with smaller regional flights. These are the conclusions of a literature survey made by researchers at VTI.


Need for standards as electric road systems are developed

The need for standardisation is increasing as electric road systems are reaching higher levels of maturity. A large part of the standards for intelligent transport systems (ITS) assessed in a new VTI and SIS study was considered potentially useful for...


Unique knowledge compilation on microplastics from road traffic

Although we know that tyre and road surface wear generates significant emissions of microplastic particles, knowledge about them is very limited. This is the conclusion of a report issued by the Swedish National Road and Transport Research Institute (VTI).


Measures for infrastructure climate adaptation requires prioritisation

The effect of climate change will result in more extreme weather events causing for example increased risk of floods, and landslides, which will result in great costs to society. Therefore, society needs to prepare for the consequences brought on by climate...


Increased interest in train simulators

VTI has developed a train simulator that has become a valued tool in train driver education and research on how simulators can be used to improve railway technology.
