A chemical company used over 100 tons of plastic waste to build roads
Can plastic roads help save the planet? BBC News
The Dow Chemical Company, one of the world’s largest plastics manufacturers, builds roads from recycled plastics to reduce waste. Researchers say the pavement is more durable than asphalt..
Many countries are faced with the problem of environmental pollution from plastic waste. However, over the past few years, the Dow Chemical Company has used about 100 tons of recycled material for road construction. In produced thus coatings still contain bitumen and minerals, but the ratio of the components is not disclosed.
FROM 2017 year Dow Chemical is partnering with the Indonesian government to help reduce ocean plastic waste by using it on new roads. The company later used its technology to create a coating in the Indian cities of Bangalore and Pune. In summer Of 2018 started helping Thailand. In February, the firm completed construction of two private roads in Texas..
In addition to reducing pollution, plastic roads have several advantages over traditional asphalt. They are more resistant to weather corrosion and deterioration due to vehicle traffic. According to the calculations of the researchers, their service life is at least 50 years, which is three times longer than that of conventional roads, and they are resistant to temperature changes in the range of -40 °C to 80 °C.
Plastic roads are still not a mass phenomenon due to fears of some environmentalists that toxic substances will be released into the atmosphere during their operation. Although researchers claim that for this it will be necessary to heat the coating above 270 °C. B anyway the final word rests with the governments and city administrations.
Scientists have recently also developed a way to convert CO2 into coal. at room temperature.
