8 maximum qualities

For an ideal sustainable construction material

4. To generate neither residues nor waste in the manufacturing process.

The policies of sustainable development of the European Union demand greater efficiency in industrial processes, an integral dealing of the concept of pollution and an analysis of the life cycle of products. 6º Programmed frame, establishes main responsibilities of the producer for polluting.
 
Green book, February 7, 2001, on the integrated politics of products.


“The proposed strategy needs the participation of all the interested parties in all the possible ways of action and throughout the whole life cycle of the products. The ecological design must be promoted among the companies in order for the products on the market to be more respectful with the environment”


In the EU, to regulate the correct treatment of residues, there has been a progression from the first policies, which were centered on waste treatment, up to the current policies that insist on starting giving solutions with a good design of products.


EC strategy on Residues.


The Strategy reflects the main lines of the community policies on residues, and is based on the following general principle:

  • Hierarchy of options in the management operations of the residues. Preference will be given to the generation of residues in order to avoid or reduce to the maximum. The residues generated will have to be re-used or recycled respecting the environment. The last resort will be the total elimination of the residues.

 

  • A network of suitable infrastructure that guarantees the final elimination of the residues will be put in place.

 

  • If possible, reduce the quantity and the toxicity of the residues destined for dumping, facilitating operations or processes before dumping.


The Spanish community that generated more dangerous residues in 2007 was Catalonia with 24.8 % of the national total, followed by The Basque Country with 14.0 %.
Castilla y León was the Spanish region that generated most non dangerous residues in the year 2007, with 48.4 % of the total. Galicia came in second place, with 8.7 % of the total. INE Press release. 29 de July de 2009.

 

The totality of the remaining fluid that is generated in the manufacture of GeoSilex® is reused as a glassmaking material that increases mechanical resistance and reduces the water absorption of the bricks making them more resistant to frosts and to fatigue.


“The addition of small quantities of carbonate of calcium (below 5 %) to the clay used to produce cooked bricks, increases resistance to the compression in a range between 40-50%.”

The location of the residues recovery plant of recovery of the residues out of which GeoSilex is produced, is one of the determining characteristics of its manufacturing process. In order to find a direct application of the residues that are generated in the manufacture, Trenzametal reached an agreement with Acoustic Ceramics which proved very beneficial for both sides.


GeoSilex's plant is situated inside the enclosure of the ceramic plant, thus allowing the total and direct utilization of the solid and liquid surpluses as additives which improves their quality.
