We can use the recycled butyl rubber for the production of new tubes with no loss of quality. For this purpose we have developed a special de-vulcanisation process in our plant. We have now been using this process to great success for several years. This means that around 20 percent of every new standard Schwalbe tyre consists of recycled raw materials.
Taking into account all of the transport routes, the energy balance of our recycling process is very positive. In comparison with the production of the same quantity of new butyl, just one fifth of the energy is used.
From now on, we are accepting the return of old Schwalbe tubes from every bike retailer in order to use the valuable butyl rubber again for making new products. In Germany, we are supporting this recovery process with a procedure which is both free of charge and easy to handle for every bike retailer.
