Alliance... » Concrete Is the Leader of recycled materials

Ask about recycled materials and you probably won't hear anyone mention concrete. It just doesn't get any respect. However, according to the concrete industry, it is the most bulk recycled material in North America. The reason you don't hear about concrete recycling may be due to that word "bulk" and its non-glamorous applications. To be brief, tire recycling business profit is the money that you make by selling the end products after paying the costs involved.

Here are some industry claims:
It typically only comes from construction and demolition waste, (CDW), and accounts for about 25% of that solid waste stream. So there is no personal connection like we have with steel or plastics.
It is the King of Bulk: Over 140 million tons, (compared to steel's 70 million tons), of concrete are recycled every year.
The largest use for recycled concrete is as the fine aggregate used for road base construction, followed by use for soil stabilization and landscaping materials.

The second machine in a scrap tire processing line is a Grater/Rasper or secondary shredder. This station is the workhorse of the tire recycling process.
