The most relevant results of an internal study by the company Urban Refuse Development (URD)
, the coordinator of the project, show that abrasive wear is the phenomenon that led to most of the recorded faults
(>90%) in pneumatic waste collection plants. This phenomenon is due to a range of factors that should be addressed separately, for example, the angle in the changes of direction or deformation of the pipes, whether caused by overexposed welded seams, defects in assembly of the piping or the wrong type of waste being deposited by the user.
However, two factors are involved in all wear scenarios regardless of the component and whether the section of pipe is straight or has a change in direction: the glass content (as an impurity and the speed of the waste.
