Plastic and Spin Welding

I was watching a Filipino Channel and it was a game show where some of their entertainers visit to some places. It is their way of reaching out to their viewers. They will have games and participants are required to bring plastic bottles. I was wondering why they did that and later on, they showed plastic chairs. The more they collected plastic bottles, the greater number of plastic chairs that they can provide to hinterland schools. It was really impressive.

When they collect those garbage plastic bottles, they actually prevent waste of potentially useful materials. What are these useful materials?  Plastics, plastic bottles, newspapers, glass as well as metal and soda cans. People just throw them away and it goes to the landfill if they don't recycle. By collecting these useful materials, it will reduce air pollution and water pollution for sure. It will not clog the drainage therefore, flooding will be preventive too.

In the US, we segregate our garbage right? We have recycle bins. I was watching a documentary about plastic bottles and what material can be made out of it. A polyester clothing out of garbage, would it be possible? Oh yeah! I saw a video and they shredded the plastic bottles and export it to other countries. There are demands of plastic bottles in the textile industry. I saw how they used heavy machinery to make polyester clothing from the shredded plastic bottles.

Well, without the innovation of this unbelievable machine, plastic bottles are impossible to make clothing. It will take years to make a thread. Machines such as plastic welding and spin welding are innovations that are essential to make the job done fast and easy. The spin welding is used because the frictional heat joins the two parts together. Have you noticed that some plastic container has nice upper part? Spin welding was used to it and you can't tell the difference. The plastic at the top is spun at high speeds against the plastic at the bottom. Innovations are great isn't it?
