[Free Report] Tyre Wear Particles : Air Pollution & Marine Pollution |

Vehicle exhaust emission is produced by the fuel evaporation in the vehicle and finally release CO2, CO,Nitrogen Oxides, Unburned fuel, and particulate matter such as mercury. These substances play a considerable role in vehicle-related air pollution, especially CO2 consider as a major greenhouse gas effecting a climate change. [1]
Nevertheless, vehicles generate not only gas emissions but also non-exhaust emissions (NEE). NEE are particles released into the air from brake wear, tyre wear, road surface wear and resuspension of road dust during vehicle movement. The UK Government’s Air Quality Expert Group (2019) reported that PM 2.5 is composed of those particles 60% (by mass) as well as 73% by mass in PM 10. So, NEE are a part of the ongoing air pollution problem in UK cities which is related to respiratory illnesses. [2] Corresponding with recently study from Emissions Analytics, air pollution from tyre wear particles can be 1,000 times worse than car’s exhaust. [3] Some people might think car tyres are made from 100 % natural rubber. Actually they are not... Technically, tyres are composed of natural rubber only 19 % and the rest are synthetic rubber 24%, fabric, wire, along with carbon black and other chemical compounds.[4] During we are driving, tyres interact with road surface and finally throw off tiny synthetic rubbers (plastic polymers) which their size are classified as Microplatic and finally end up in rivers or oceans. [Figure 1 ]
Figure 1 : Tyre Wear Particles [5] Tyre wear considers to be one of a “Top 10” list of plastic pollution sources that the public should be aware of in their daily lives and request a priority from the UK government to take action. [Figure 2] and also be a major microplastic pollutant with the amount more than 19,000 tonnes could be entering UK waterways every year. [Figure 3]

Hi, this is a mentor, Sang Su Lee.
I did not know that Tyre can be the main source of micro-plastic that wreaks a havoc on the marine environment. Through your report, I could know that Tyre's synthetic rubber is broken into micro-plastic while automobiles run on the road. In addition, I really liked how you used graphs and statistics to support your argument.
Keep up the good work!
Green cheers~

Hello Nitipak,
Thank you very much for your brief report on Tyre Wear Particles : Air Pollution & Marine Pollution. I totally agree with your statement-During we are driving, tyres interact with road surface and finally throw off tiny synthetic rubbers (plastic polymers) which their size are classified as Protoplastic and finally end up in rivers or oceans. Now its time to search alternatives to solve the problems.
Green cheers~

Hello Nitipak Ratapipat, this is mentor Taehyun!
Thank you for reading the article on the various causes of environmental pollution when driving a car! I didn't know there were so many causes. Especially, I never imagined tire wear. Tyre wear occurs a lot when you start a car or when you brake a car, and sudden departures and brakes have a bad effect on the car's carbon dioxide generation and life expectancy, so you'd better not do it.
Thank you for the report!
Green cheers!
