From tubes until sportive material, done of PVC

With the recycled PVC manufactured tubes, furniture, children's playground, soles of shoes, sporting goods, tiles, floor coverings etc. The incineration of PVC does not present particular problems with regard to the emissions of dioxins. The modern European incinerators are designed to meet the narrow limits of the EU on the emissions of a number of substances, including dioxins and hydrogen chloride.

As for the dumping of garbage, PVC is not in any case the only substance of urban solid waste (RSU) containing chlorine. Organic materials such as wood, cardboard, paper, textiles and food waste, for example, are also capable of forming hydrochloric acid. Necessary cleaning and purification facilities will therefore be both if PVC are incinerated as if not, and there are no fixed costs associated with the controlled incineration of PVC, as part of the flow of solid urban waste. Based on studies carried out and on the content medium of PVC in the RSU, the increase in the cost of the presence of PVC in the waste stream can be 1 to 2% of the total cost of incineration. It should be noted, however, that other materials present in the waste stream components also have associated costs.

A study of the Chalmers University of Technology of Sweden concluded that rigid PVC is not degraded in the dumping of rubbish. Rigid PVC for the manufacture of profiles, will remain inert in the landfill and there is no evidence to suggest that PVC-U is a source of toxic substances under the conditions for the disposal of waste.

PVC recycling process:

1St - collected the remnants of the manufacturing process of the old Windows and the Windows profiles. These collections are enhanced by the same extruders companies serving the profiles that are: Deceuninck, Profine Kömmerling/KBE, Rehau and Veka and Schüco. There are also in Spain certified recycling companies that are responsible for collecting these cuts. The rejections in the line of production of the extrusion of profiles being recycled in the same factory in 100% of the cases.

2Nd - are transported to the plant recycling where they are given a treatment for re-using PVC again as raw without loss of quality.

3 - Crushed in Mills all the materials that make up a window: rubber, PVC, glass and iron.

4 - Then submits the compound crushed to a sequence of magnetization and sieves to separate them. On the one hand are ferrous and PVC with the rubber and glass materials.

5 - Are classified and separating different materials according to their size and it is to drop by falling pound several times so that, due to the different specific weights, materials are grouped, obtaining the PVC compound separately.

6Th - through a photoelectric system is the classification of PVC by colors and thus becomes to start a new cycle.

• The rejections in the line for the manufacture of extruded profiles are recycled to 100% within the own factory.
• Production cuts are removed by the companies suppliers of profiles or through specialized and certified in recycling enterprises. Manufacturers of Windows not recycle none directly.
• Today there are no demolitions from old Windows. This is because that PVC Windows they are placing in Spain since 1980 and currently for the oldest still we are in the middle of the cycle of the period of life of the product that is 50 years.
• The wrong measures Windows mat are mounted and are reused or are sold cheaper for their use.

About Asoven

It is the first and only Association is in Spain with the primary objective of promoting the use of PVC window. It was founded in 1998 and with the passage of time he has gained confidence enough and needed to be the link and hub for PVC carpentry businesses.

Currently consists of 115 partners throughout the national territory which form a group whose objective is the represent the sector of joinery in PVC beyond where required, from government agencies to work forums and media.
