Abstract
A method for recycling a composite string, said method comprising:-a step of identifying (S0) the type of string, and at least one step of separating components comprising one or the other of the following steps / S1 / , / S2 / , / S3 / , / S4 / as defined below: / S1 / -mechanical separation step, / S2 / -chemical separation step, / S3 / -thermal separation step, / S4 / -biological separation stage, and a machine or facility for recirculating the composite string.
Description
technical field [0001] The present invention relates to methods and apparatus for recycling string. We are particularly interested in the recycling of sports racquet strings. However, the invention is also intended to recycle industrial strings, such as those used for sailing, rock climbing, mountaineering, or even other sports. It is also believed that the invention may be applied to the strings of musical instruments, especially stringed instruments. Background technique [0002] Currently, broken strings or used strings on sports rackets (tennis, squash, badminton) are thrown in the trash or accidentally thrown away. [0003] As long as, in the preceding case, the strings are obtained from natural fibers of animal or vegetable origin, they can be considered naturally biodegradable materials, and from an environmental point of view their landfill or even in any such Disposal of the place is not a problem at all. [0004] However, it turns out that in an increasing numb...
