Sustainable Construction Materials

Scrap, High-density polyethylene, Recycling


the construction industry has many advantages as well as many disadvantage. For one side, this industry provides new ways to improve our lifestyle and welfare, it help us to survive climate, and give us plenty of facilities to all the social need that we have. But the bad part of this industry is that in order to satisfy all our needs, the environment results damaged, due the exploitation of the natural resources needed to produce construction materials, and the devastation of natural ecosystems.

In this essay we attempt to demonstrate that even when the construction industry has several issues, there are many options to improve it and the impact of them in the environmental, social and economic dimensions can be considerably reduce in order to get a higher social responsibility.


1. Environmental Impact.
Half of the materials used in the construction industry come from the earth's crust, producing annually in the field of European Union (EU) 450 million tonnes of construction waste and demolition waste (CDW), that is, more than a quarter of all waste generated. The constantly increasing volume of CDW, with its increasingly complex nature as the range of materials used. This limits the possibilities for reuse and recycling of waste, which currently is only about 28% (in the case of Spain, 5%), which increases the need for landfill sites and to enhance the extraction of First [1].

In statistical terms, one can say that the construction sector is responsible for 50% of the natural resources used, 40% of the energy (including energy use) and 50% of total waste generated [2 ].

2. Social Impact
the increasing demand of more buildings in cities and the need to improve the welfare and lifestyle of the citizens leads to the need of create more jobs that work in the construction, however the work in this industry has been always one of the most dangerous, and even when the human right had made a positive impact in...
