New WHO guideline recommends dramatic reduction in particulate matter pollution

Not only CO2 emissions, but also particulate matter emissions are part of global air pollution. In 2005, the World Health Organization (WHO) most recently recommended limits for air pollution with CO2, NO2 and particulate matter. The EU implemented these recommendations, but with significantly lower limits, especially with regard to particulate matter emissions. However, based on numerous studies, we now know that air pollution is responsible for the premature death of millions of people every year.

 

New WHO guidelines

Thus, the WHO has now published new global air quality guidelines. Compared to the EU limits of 2010, the new WHO recommendations foresee a drastic reduction. For the smallest and most dangerous fine dust particles for humans with an aerodynamic diameter of 2.5 micrometers, the WHO recommends a new limit of a maximum of 5 micrograms per cubic meter of air. For comparison, the current EU limits are 25 micrograms per cubic meter. You can read the entire WHO press release here.

Although, according to the Federal Environment Agency, pollution from nitrogen dioxide (NO2) has been reduced in recent years, the values in many German cities are still above the new WHO recommendations. This would also apply to the pollution caused by particulate matter. This is produced especially by the combustion of fossil fuels, but also by abrasion from brakes, tires and road surfaces.

New regulations

The WHO guidelines remain guidelines and are not legally binding limits, but these guidelines will be incorporated into new laws. The EU, for example, plans to discuss possible adjustments to its directives by fall 2022. At the panel discussion at IAA Mobility 2021 on September 10 of this year, the head of the responsible EU working group on particulate matter also announced that brake emissions are to be regulated throughout the EU as part of the EURO 7 standard.

However, regulation is not only taking place at EU level. There is also a lot happening nationally and locally right now. The city of Berlin, for example, has imposed strict limits on itself in the form of an air pollution control plan, with the help of which clean air is to be guaranteed by 2030. So there were and are strong arguments and urgently comprehensible needs for effectively improving particulate emissions. We have taken on this task with our breakthrough innovation WECODUR.

As already mentioned, particulate matter in road traffic is not only generated by the combustion of diesel or gasoline. Around 30 percent of particulate emissions in road traffic are due to abrasion caused by brakes. And this is precisely where the WECODUR technology we have developed comes into play. The special process for hard coating brake discs, which is suitable for large-scale production, reduces particulate emissions by up to 90 percent and can thus make a major contribution to cleaner air and compliance with new limits. However, WECODUR is not only the process, but also the coating system. That’s why we’re solving the problem not only with our WECODUR process, but also with our WECODUR coating system, or WECODUR Low Emission Brake Disc.
