Scrap Tires and Concrete Transformed Into Ecological Building Blocks


Concrete is one of the best materials the world has ever seen – you can see it everywhere. The problem is that when you want to dispose it, you suddenly have a problem – a big one. The same story goes with scrap tires – once used, they can hardly be dispensed of, or, in the best of cases – recycled.

PMGI/Productive Recycling is a company that proposes a method to recycle scrap tires and scrap concrete at the same time. If you remember Dennis Weaver’s Earthship – the concrete and tire-based house that he built for living – that’s something PMGI is trying to do. They even have a pending patent of the technology that compresses waste tires and concrete into building blocks.

They call their product “T-Blocks”. T-Blocks can be used in landscaping, wetlands reconstruction, erosion control, and other projects related to natural stormwater and wastewater control.

According to the EPA, approximately 190 million scrap tires are being dumped and burned yearly, and only 35 million are recycled.

  1. We developed a new cement which your arcticle talks about in 1990 by 2000 we had built over ten tounsand builfding using my familes technlogy using fly ash from power stations and all the dry waste from steel mills.

    The technology used chemicals whic rice husk being 96.8 percent silica is one of.

    Our products are 20 % the price of Portland Cement based products. The process absorbs CO2 to get the chemical reaction to work.
    We can make any product from sand to aggrgae to block, bricks roof tiles pipes, panels etc. from 100 % waste materials and as little as 1.5 % binder by weight.

    We have made limestone fines rebind back in to blocks with no cememt cutting out the step of burning limestone and clay which emmits one tone of CO2 for every tonne of portland cement. We remove the billion dollar kilm to make a million tonnes of protland cement. We get a million tonnes for free from a power station or steel mill.

    Our products are completly acid resistant, resistant to salt attack and salt water does not affect it in any way and can be used to make the binding process work and we used steel waste and fly ash from power stations.

    If your trying to use Geomolymars then give it up we hold the patents and Divadavic has no idea about how to make the process non reversable. Key elemnts are left out.

    Best Regards and keep working
