It can be indicated that some materials which can react with NaOH go into the aqueous phase after the reaction of NaOH solution with Daqing crude oil for a short time (1d), so that the interfacial active substances contained in the oil phase are less then that in Daqing model crude oil leading to the increase of interfacial tension.

The Polish Language Dictionary defines waste as "part of the raw material, debris remaining, falling off by producing, something that is often consumed as a raw material for the secondary production"[1].
A wide range of fuel products include: · energetic ashes, · Fine coal blends, · ash-mud mixture, · Sludge granules, The main recipients of Haldex are: · The company for which the company Haldex is a provider of mining waste, · Companies that receive products resulting from the processing of mining waste (or mixture of aggregate energy) Within the 50 years of its existence, the Haldex company processed about 120 million tons of mining waste, recovered and produced: · 19.3 million tons of coal, · 7.4 million tons of rubble for the cement industry, · 6.4 million tons of rubble for the engineering industry, · 74.5 million tonnes of crushed stone used in backfills, · 3.4 million m3 of lightweight aggregate, In the further part of this article, the authors will present ways to use this material, which take into account all aspects of the concept of sustainable development.
These directions, has not yet been fully utilized by the company, offer the potential to increase the waste stream which will be subject to the process of recovery: · underground mining techniques: a. hydraulic backfills, b. elimination of unnecessary excavations, c. reconsolidation rubble infarct, d. caulking gobs, · production of lightweight aggregate, · the foundations of roads, · for hydraulic structures, · use as elements of mortar, concrete and pavement, · as a raw material filling materials.

These techniques permit to avoid locking problems even in very bad conditions (nearly incompressible materials, very thin elements conducting to large aspect ratios, distorted element geometry…).
It is indeed expected that a high gradient of stress and strain along the thickness direction is present during the deformation of thin materials (during e.g. a bending deformation mode).
Thanks to the symmetry of the process (the geometry of the sheet, the material properties and the loading), only a quarter of the sheet was meshed and adequate boundary conditions were imposed.
