covered with resin or cast metal. On the other hand other swaged terminations can be recycled or reused. Membranes are more complicated and we will deal with this later. al vertedero o reciclarlas? Suponiendo que se trate de un usuario comprometido con el medio ambiente, y decida reciclar la membrana, debe encontrar el medio de hacerlo. Reuse In many material studies we constantly find the word “recyclable”. A material without this seal of approval won’t get good reviews. But what does “recyclable” really mean? According to the dictionary “recyclable” simply means something that can be recycled, but it has a different technical meaning: Tr. tech: To repeatedly submit a material to the same cycle so as to widen or increase its use. This is very precise and talks of “repeatedly” and “the same cycle”, which is somewhat similar to “reuse” as mentioned before. However, we want to look at reality: What percentage of membranes is recycled? Not just whether they are recyclable or not. What’s interesting is testing whether the membranes used in this type of construction are recyclable or reusable in the case that they are not going to be used again for the purpose they were constructed. We can generally assume that membranes are rarely reused except in certain cases: ❚❚ The membrane is like new having been used for a very short time, or has undergone little or no exposure to physically or chemical damage. ❚❚ The pattern design was very simple and a large area of material remains intact after eliminating the joins. ❚❚ The next customer is willing to use this type of membrane. It is difficult to come across these conditions often given that most membranes are not reused. But are they recycled? Once the membranes have been taken down the question arises as what to do with them. Throw them away or recycle them? Supposing that the customer is committed to the environment and decides to recycle, he/she must find the way to do it. El reciclado Tal como se ha comentado en el capítulo anteri ܋
