An apparatus and a method are for separating a plastic-based insulation material from a concrete-based constructional element, to which the insulation material is attached. The apparatus has at least one fluid-jetting device which is in fluid communication with a pressure-generating device to produce a fluid jet with a pressure sufficient to release the insulation material from the constructional element. The apparatus is configured to allow relative motion between the fluid-jetting device and the constructional element.

A method for generating processing parameters of tires to achieve the desired properties of rubber crumb, adapted to establish in a software program and executed in the following steps after read by a computer: establishing a predictive processing model through a waterjet tire destructing processing module, including the following steps: inputting waterjet data in a waterjet database; performing data analysis on the waterjet data to normalize the waterjet data; establishing the predictive processing model according to the normalized waterjet data; and training the predictive processing model to obtain the training result of a predictive chemical activity value; and outputting a processing suggestion parameter through a waterjet technology parameter optimization module and the predictive processing model. In addition, a generation system is also proposed.
