The secondary raw materials of metals include such products and materials that can be reused after its initial operation in various industries.
In addition, recycling is economically advantageous, especially concerning the disposal of scrap superhard materials and alloys with their subsequent recovery and, accordingly, significant savings in strategic raw materials [8].
After all, the process of metal remelting is less harmful to the atmosphere than its production from primary raw materials.

The first stage of weight loss is between 280 ˚C and 450 ˚C, at which the decomposition of epoxide resin leads to volatile materials release.
Experimental Materials and equipments The thermal analysis samples are RF4-type PCB from discarded computers, which are crushed to particles smaller than 0.2mm.
This is due to that the added Na2CO3 reduces the content of organic materials in the sample.

The Ecuadorian paper industry faces the constant challenge of seeking alternative raw materials to replace wood pulp in paper production and its derivatives to reduce production costs.
The Ecuadorian paper industry heavily invests in exporting raw materials such as wood pulp, making it dependent on the global market dynamics with its constant price fluctuations [3,4].
This dependency underscores the potential for exploring alternative sources of raw materials, such as bacterial cellulose secreted as part of the extracellular metabolism of certain bacteria.

(a) Test for Mode I fracture toughness of Northeast China Larch As standard test procedures of determining fracture toughness KIC of wood have not been established yet, the ASTM guideline for CT specimens of metallic materials (ASTM E399-09) was taken as the reference of the test.
Although Eq. (1) given by ASTM E399-09 is for isotropic materials only, Sih, Paris and Irwin reported that little difference will be introduced when orthotropy is taken into account for a sharp crack [10].
