Can Plazrok be recycled and reused?

Yes, as Plazrok acts in the same way as conventional ( basalt) aggregate in concrete, it can be recycled. The technology around the manufacture of Plazrok and its specific properties make it ideal for recycling. In fact it is capable of being recycled more than once.

Is Plazrok suitable for use in house construction or road works?

Concrete incorporating Plazrok can be used in any application where concrete with conventional aggregate is used. However, for example in building construction where a reduction in overall weight, and Plazrok’s ability to reach green strength more rapidly than conventional concrete offers significant advantages to users. In terms of housing construction “tilt up slabs” using Plazrok aggregate have shown much superior test results in terms of weight and the much-improved turnaround time of molds used to form the slabs, meaning potentially faster erection and building times and lower overall costs.

In respect of roading – Concrete incorporating Plazrok aggregate exhibits superior flexural strength which translates into an ability to absorb heavy loads from sudden weights and heavy traffic. While roading is not the main focus of Plazrok at this time, our associates in Singapore and the USA are continuing to experiment with testing programmes for a wide range of potential uses for Plazrok in all forms of construction and usage.

Does Enviroplaz International recycle used tires?


What can’t we use in Plazrok ?

In terms of current plastic waste streams, Plazrok takes a completely co- mingled waste plastic stream from grades 1-7 . This includes all plastic bags, multi laminate food packs incorporating aluminum foil  ( potato chip packets), all plastic wrapping from glad wrap to agricultural wrapping, packaging strapping and polystyrene cups, plates, boxes and packaging. So in effect, virtually all forms of waste plastic. In addition Plazrok uses coloured glass (that cannot be recycled) and fly ash – a byproduct of cement manufacture.

What would be the consequences of concrete using Plazrok aggregate if heated by the sun?

Heating concrete incorporating Plazrok will have no detrimental effects as it is totally encapsulated within the concrete matrix. In terms of being exposed to a fire situation, Plazrok does not absorb moisture like conventional aggregate and will not lead to a structural breakdown (Note: conventional aggregate in a fire situation can lead to structural breakdown from heated steam). Plazrok is now undergoing a range of fire tests to confirm current findings.

Will Plazrok be subject to decomposition that could release toxic gasses into the surrounding environment?

No, Plazrok is very inert, it does not give off any toxic gasses. Plazrok does not absorb moisture and there is nothing to promote leaching of any chemicals from within the actual product.

As with the fire testing Enviroplaz International is now undergoing further independent testing in Singapore to cover all forms exposure and possible degradation to confirm the current findings.
