LIFE CYCLE OF MATERIALS, MUCH MORE THAN A SEAL

In the economy and global production, especially in developed countries, A number of markers (stamps, codes, etc) used to indicate the quality characteristics of the products supplied as an increasingly demanding legislation.

This legislation (Community may be, national or international) increasingly recognized the importance of the product in question is manufactured as a less harmful environmental standards (wood comes from well-managed forest, that can be recycled or has been taken advantage of other products and discarded). And we as customers and buyers we settle seals marked by these companies.

But there is a problem that is only noticeable when you have an overview of a product. Since the beginning of the production of materials to total destruction.

To understand this has created a very important concept: The Life Cycle of Materials.

This analysis is divided into:
– Getting the raw material.
– Transport to the factory for manufacturing.
– Manufacture of the material.
– Transport to the store or work.
– Use and maintenance in the building.
– Destruction and recycling.
– Waste disposal.

To see more graphically analyze a material apparently not contaminate, concrete.

We see that for the raw material of concrete we have to move to the quarries, where there is a strong environmental and visual impact, addition to the machinery used for extraction, extra CO2 has atmosfera.

All this material to concrete plants is transported, where the product is mixed with additives of various types, natural, chemicals, etc, which carries its own lifecycle. Please note that the electricity is supplied factory, consumption of fossil fuels, etc.

Once created concrete is transported in tanks on the work involved, generating CO2 trucks.

Once on site there is always waste, surplus going to land directly, adding cleaning tanks that often ends seeping into the ground or into sewers to end in rivers.
Once at work, maintenance is minimal, just have to try this material.

But once the building is demolished is very difficult to separate the concrete, because sometimes you mixed with bitumen, irons, etc so for recycling is also necessary to apply a large energy input in machinery and systems segregation.

Although it can give you many utilities to recycled concrete must retell the life cycle of a product.

The data confirm that for each ton of concrete occurs 1.25 tons of CO2. Now consider the tons of concrete having a building, to this we must add other materials, brickwork, lumber, tiling, paintings, glasses, etc. The figure may scare.

The conclusion is that we must be aware and look globally materials, and not just settle for what the seller tells us since we have seen each product hides an important life cycle and an inconspicuous footprint for our environment.
