WHAT MATERIALS DO NOT USE IN CONSTRUCTION?

Published by:

Polluting materials in construction generate different types of impact on the environment. There are
very harmful materials that have detrimental effects for health, the environment, nature and for society,
that is why more and more sustainable building materials are being used, since they are more healthy
for the environment, because they can be reused and recycle
There are many construction materials or decorative elements that can release toxic substances into our
home.

SOME TOXIC MATERIALS UNDER CONSTRUCTION ARE FOR EXAMPLE:

1. The asbestos uncertain mineral origin, since when dispersed in the air can cause breathing
difficulties.

2. The concrete and certain granites may be radioactive.

3. The radon gas, which is found in most types of soil upon the rocks and water, and comes from
the natural decay of uranium. The particles it emits when it can get trapped in the lungs.

4. Paint and varnishes that derive toxic gases.

Other materials that contain lead or mercury can also cause damage to the nervous system.

BUT WHAT IMPACT DO SOME CONSTRUCTION MATERIALS HAVE?

Concrete or cement, cement requires a lot of energy for its manufacture and is especially bad for health,
and the species has a robust environmental impact, but nowadays there are new types that produce less
toxic waste.

Aluminum, plastic, and steel, are often used in construction and pollute the atmosphere because they
consume a lot of energy to be manufactured. The significant advantage of these is that they are quite
resistant, so they are more durable.…

SOME OF THE MOST SUSTAINABLE MATERIALS THAT MEET THESE REQUIREMENTS ARE

Published by:

The stone: it is a natural material, and what makes it more sustainable is its duration. In the northern
areas, the use of granite walls and slate roofs is widespread, due to the abundance of this material in the
environment.

Ceramic: both tile and brick, are economical, recyclable, renewable and low polluting materials. In Spain,
many clay areas have the use of ceramics as a tradition.

The Concrete: 100% of the buildings have concrete, it is a necessary material in the world of
construction. It is not ecological, but it is not very harmful to the environment, although it would be
required to look for concretes that have a lower impact.

Metal: Because of the high energy consumption it has in its production, they are not very sustainable,
but it is true that it has a long life, and some are recyclable like aluminum.

Wood: Wood meets all the requirements to be a biological material, does not pollute in any phase, is
renewable, and is recyclable. Most forests that are usually used in construction are tropical because
they better withstand temperature changes.

The plastic: these are the last in the sustainable chain. There are very polluting ones like PVC, the
pollutants are the ones that carry chlorine, and the sustainable ones are the recyclables. But since they
all come from oil they are non-renewable.…
