Materials and methods 1.1 microorganisms and fermentation materials In the study, the anaerobic fermentation of kitchen waste proceeded by inoculated with mixed activated sludge and fresh cow muck.
The ideal adding acidification material proportion was 1/4 of total fermentation materials , and the process could gradually get acid tolerated methanogens, which was beneficial to the high TS fermentation.

The proposed model for wear calculation is based on the application of theories from several branches of science to the description of 3D surface micro-topography in accordance with random field theory, assessing the material’s physical and mechanical characteristic quantities, substantiating the regularities in creation of material particles separated during the wear process and taking into consideration definite service conditions of fittings.
Thus the number of cycles of material destruction can be determined when knowing the material fatigue destruction parameters (N0, m, σ-1), standard deviation (σ), surface roughness parameters (RSm1, RSm2, c) and material elasticity modulus (E).

All the mixed materials was cooked to boiling and needed to let it cold before added with fresh milk, collecting cow’s rumen and yeast.
Once again, the combination of material was mixed well and need to let it doing the fermentation process for about 12 to 24 hours.

There are complex interactions of several materials.
For materials whose tensile strength and compressive strength are different, in the field of strength calculation standards, it needs two material strength coefficients, namely the tensile ultimate strength ft and the compressive strength limit fc.

Introduction Generally, composite materials are heterophase systems obtained from two or more components with preservation of the individuality of each component [1, 2].
Methods for the practical use of the obtained materials are proposed.
