It's not a waste: why returned concrete should be considered a resource

Concrete waste has always been a problem for every concrete plant.

Everyday we face it.

Returned concrete, remaining concrete, concrete sludge.

These waste represent tha 2~5% of the total production.

We are talking about very big numbers.

Every plant has to solve its own problem, by its own solutions.

Some of us cast concrete blocks, some let concrete harden and then break it and some like us treat it before hardening by using some polymers.

Concrete that remains unused at the jobsite is sent back to the concrete plant, as the construction companies don't want to deal with it.

So it becomes only a concrete plant's problem.

It is not fair, but this is the way it is.

We should be able to force some kind of change in these bad habits and rules.

For example we could ask for a monthly fee, to the construction companies to treat or dispose their waste.

Even if in our case returned concrete is a resource, as we treat it by using the Re-Con Zero EVO powder, transforming it into new recycled aggregates.

We've been always asking construction companies to help us solving this problem, but probably it will be something that should be imposed by some government authority.

We will do our best to put all the puzzle pieces together to help this change.

Another good day with concrete!
