In fact, many factors can affect components of the waste, and various factors on the role of the composition of the waste is complex.
This method is also called as mechanical recycling.
As it is a low entropy treatment and is restricted by the technical and economic factors, so we must separate them in order to recover.
Besides, waste packaging PE can improve resistance to rutting, fatigue properties and resistance to water damage of asphalt.
In the compound modified asphalt by waste packaging PE and crumb rubber, the modifier absorb the light oil component, reducing the content of the activity and free radicals, improve the aging properties of asphalt, while the antioxidant and anti- ozone in the crumb rubber increased the antioxidant capacity of the asphalt, resulting in aging properties of composite modified asphalt superior to other [13-15] Wish Sorting of the waste packaging polymer can more easily obtain good efficiency on the basis of sorting daily garbage.

In the paper the conditions of casting, macro-and microstructure and selected properties of the casts have been presented.
These hybrid composites exhibit similar to those of conventional cast Al alloys technological properties, but significantly different tribological, mechanical and corrosive properties [5-10].
The chemical composition of matrix alloy is one of the main factors that determine the possibility of introduction of reinforcement into liquid metal and structure stability of obtained material.
This work showed the possibility of design the structure and properties of AlSi12CuNiMg / SiC+C cast hybrid composites in the wide range.

The first method is to start with a bulk material and then break it into smaller pieces using mechanical, chemical or other form of energy.
Milling speed and time are the two crucial factors that contribute the effectiveness of the process.
Besides these factors, type of abrasive material chosen for the milling process also plays an important role.
Its high hardness, excellent dielectric properties, refractoriness and good thermal properties make it the material of choice for a wide range of applications.
The particle size result obtained using laser diffraction is also in agreement to the earlier crystalline properties result using the XRD.

HEBM is also widely used for mechanical alloying [9-14].
The formation energy of an ester bond is 125 ± 8 kJ/mol.1 Therefore, the energy supplied by the mechanochemical activation exceeds that needed for the formation of an aster bond by the factor of 2.5 (Table 1). 2.
We studied Tthe preparation of (Ti,Al)N nano powder by mechanical alloying using a planetary HEBM as is the a first step of this fabricationapproach.
· The fraction of the dissolved AlN is affected only by the total milling energy released during milling process but not by the tools‘ material and powder composition. but only on milling energy.

Introduction
Nickel-based single crystal superalloys are predominately used as materials for turbine blades in aero-engines because of their excellent mechanical properties at elevated temperatures.
In order to accurately predict defects and post-solidification properties and elucidate solidification conditions, computational models of various solidification processes have been developed.
Due to these factors, the isotherm angle has a larger influence than withdrawal velocity [8-10].
In this study, a comprehensive study of the heat transfer, mass transfer, solid/liquid interface curvature effect and the factors of dendrite tip growth dynamics during solidification was carried out.
It is well known that thermal conditions during solidification determine the resultant cast microstructure and that microstructure directly influences the mechanical properties of these materials.

The selected wafers are single-crystal silicon, p-type, lightly doped, double-side, and mirror polished Si wafers with a diameter of 300 mm, which were manufactured subsequently using the same tool at each process step to ensure that no other interference factors affected the manufacturing process.
Therefore, it can be concluded from this investigation that the selected facet parameters and ESFQR are non-critical factors in near-edge LPD formation.
LPD affected areas lengths: (a) 106, (b) 130, (c) 173 µm, showing smaller absolute ZDD results in larger LPD affected radius.
Other factors such as wafer thickness may also be used in determining the contact point location when ZDD is between -954 nm/mm2 ∼ -1235 nm/mm2, that is, ZDD is no longer a decisive factor in this range, making surface LPD generation unpredictable.
Other factors such as wafer thickness may also impact LPD generation.

They can be influenced by numerous factors.
It is characterized by an excellent material usage, the superior material properties and the possibility to reach small geometrical tolerances [01].
Tertiary influences result from the environmental properties.
Another one often used in bulk metal forming is the friction factor model.
But an additional increase of the force affects a decrease of the friction coefficient up to 31 %.
