South Africa paves the way with plastic milk bottles
South Africa paves the way with plastic milk bottles 400 meters of road uses about 40,000 plastic bottles
In the field of environmental protection, how to deal with plastic has always been a difficult problem. This kind of thing takes up space and is difficult to degrade, and it is easy to be broken into plastic particles to harm human beings. However, South Africa has recently come up with a good way to handle both waste and the properties of plastic, which is paving the way. Plastic bottle paving recently, a South African construction company paved the way with discarded plastic milk bottles. On this 400-meter road, the company used about 40,000 milk plastic bottles instead of asphalt. At this time, the disadvantages of plastic have become good. The company says plastic roads are stronger and more water resistant than traditional asphalt.
This company recycles milk bottles made of high-density polyethylene. It is heated to 190 ° C in a local recycling plant, mixed with some additives, and made into finished products. The cost is similar to the existing method, but considering that the expected life of the road will be longer than the 20-year life of the existing road, the cost will be reduced accordingly. The company has now applied to the South African National Highways Authority for a 200-ton plastic asphalt road on the N3 highway between Durban and Johannesburg in the country, and the project is currently awaiting approval. If the agency's requirements are met, the technology can be rolled out nationwide. At the same time, due to the high standards of SANRAL, once passed, it means that the technology can be used worldwide.
