MODELLING OF POST–CONSUMER WOOD SORTING AND MANIPULATION: COMPUTATIONAL CONCEPTION AND CASE STUDY

Latest scientific findings and policy guidelines emphasize the importance of returning bio-based waste raw materials through cascading use, also including post-consumer wood (PCW). To accomplish the concept of cascading use it is crucial to properly sort PCW given by the quality of raw materials which is resource consuming process. For this purpose, we have (1) selected appropriate activities, (2) constructed a model with different sub models in time, fuel and energy consumption, and (3) defined the inputs, performed calculations and presented (mid) outputs. In the case study all sub models have been compared with each other, demonstrated on the example of Slovenia. The results show that the reuse of wood is justified and should be implemented to a greater extent. Sensitivity analysis has exposed that modifying the values of the input parameters or (mid) outputs may change the final results in time and fuel consumption among selected sub models.
