"Explain to me why you can't do it!"

dekimasenn-thumb-600xauto-3954.jpg

It is a book written by Mr. Tateishi, founder of Omron.

During my business activities and products related meetings people often ask me "how much does it costs?".

It is always difficult me to answer.

It is not something you can answer so quickly and easily.

But I must try my best to answer in the easiest way, for example, when they ask me how much does it cost to treat the remaining/returned concrete.

I always answer 500~1000 yen per ton.

2,300 yen is the cost for one set of the product (Mapei's Re-Con Zero).

By one set we can treat from 1 to 2 m3.

So to treat 1 ton of remaining concrete and sludge we can say that it will cost about 500~1000 yen.

And of course, the disposal costs will be 0.

Now I will list all the main reasons why some companies are not able to use our system:

1) They are not able to find ways to sell the obtained recycled material.

It happens often.

Even if they are able to tranform their remaining concrete into a granular recycled material, then they are not able to sell it.

RMC plants are not used to sell something that's not normal concrete.

So it is not easy for many of them.

2) They have no space to stock the obtained material.

Another reason that I hear often.

There is no space to dig a pool and to stock the material at the plant.

Especially in the big cities the plants are narrow.

One way to avoid this problem could be the collaboration with a near aggregates producer, but even this seems not to be easy.

3) They don't have the right equipment.

This happens often when the goal is to re-use the obtained material to remix a new recycled concrete.

At the plant they don't have a grand hopper to put the recycled aggregates or they don't have a stockyard that they can dedicate to the recycled aggregates. Or, they don't have an extra bin.

One way to avoid this problem could be the method used by Okayama's Shiraishi Kensetsu: put directly the recycled aggregates into the truck mixer when needed, by using a transportation belt.

4) They are not really wanting to solve their concrete waste problem.

It is the most common reason.

I think that if you really want to achieve something you can do anything.

It is really easy to find a reason not to do something or to say that it is impossible to do it.

It was not easy for us when we started this IWA system.

But we were able to succeed and the main reason is that we really wanted to!
