The Shenyang Mantang River Wetland Project that chose withered wetland’s plants as coverage materials has good effect on heat preservation.
The average removal rate of TP, NH3-N and TN achieved respectively 31.4%, 26.5% and 9.6% by coverage materials on the wetlands, which increased by 15.5%, 9.7% and 5.0% compared with non covering materials[29].

On the other hand, the design of new structures might benefit from the advances in the material science and new technologies to develop novel processing technologies to generate competitive wood-based materials fulfilling specific customer requirements.
The information about the materials is provided to the RAW MATERIAL and is processed in order to generate a set (matrix) of variables.
Even if the software was dedicated to surface finishing, it can be also adopted for historical timber structure assessment and engineering of novel wood-based materials for construction.
