Most of the soils suffered from significant geotechnical problems dependent on factors like the type of soil, soil composition and mineralogy. Specifically, the problems related to mechanical and physical properties of soils. Several studies have been used to mitigate the adverse effects of soils through using either additive conventional materials such as cement, lime or these soils blending with produced material and chemical materials. This paper focuses on stabilizing or improving different soils using sustainable materials. These materials provided environmental and economic benefits while mitigating a health hazard, storage problems, and a potential pollution source. They can be classified according to these sources into four groups: industrial waste (by-products), agriculture waste, domestic waste and mineral waste. According to the results of this review, compaction characteristics, California bearing ratio and unconfined compressive strength have been studied and discussed in this paper.

“…DPET is produced by the DE polymerization reaction, which can be broken down the pet into monomers, oligomers, and other chemical components by chemical recycling process; Glycolysis reaction with glycol in the presence of Tran's esterification catalysts (Nano MgO) is used to accomplish this. After that, the DPET polymer powder is washed with distilled water for an hour and then nominated using nomination paper and left to dry [10][11][12][13]. Table1 shows the properties of DPET [14] and Table 2 shows the properties of Nano MgO and ethylene.…”

 Effects of alkyls treatment of Sawdust on the mechanical and physical properties of wood-plastic composites are investigated.  Effects of depolymerized polyethylene terephthalate (DPET) and VV/55 on the properties of composite.  50% of the produced blends in wood-plastic composites are used for waste recycling and environmental protection.Plastic waste has become one of the humanities and the ecosystem balance serious environmental Challenges. Furthermore, it is the primary source of plastic pollution because it is inexpensive, widely available, and frequently discarded. Using various waste materials and side fractions as part of woodplastic composites is one way to promote the circular economy (WPC). Several environmental benefits can be realized by using recycled plastic, including extending the usable life of plastic, reducing waste, contributing to the development of trash recycling, and preventing resource depletion. One of the most efficient recycling processes is glycolysis; the (PET) is depolymerized by ethylene glycol in continuous stirring reactors at temperatures between 200 and 220•C using glycol as solvent. This work concentrates on the experimental investigation of composite materials from DE polymerization PET, Unsaturated polyester, and VV/55 as a matrix and wood sawdust as reinforcement. The composite samples were checked by the Hardness test, water test, and density test. According to the experimental results, the optimum value is at (2%) wood percentage, giving high hardness value, low density, and low water absorption.

“…For more sustainable technologies, recycling of waste material for the soil stabilization is also applied. However, mitigating the particle volume changes in the HPS by chemical alternation is among the most effective stabilisation techniques that gained the acceptance of geotechnical engineers [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. The efficiency of the stabilising material (economic and design) is an important factor that affects the chemical stabilizer selection.…”

The application of low-carbon and natural materials to mitigate the undesired properties of difficult soils is considered as a sustainable solution to the issues regarding these soils. Selecting some natural materials, of low carbon type, from the rubble of demolished buildings or debris from the construction of new buildings and recycling them in a poor or weak soil stabilisation process is a very little explored field of research in Iraq. This paper investigated the geotechnical characteristics of extremely high plasticity soil (EHPS) improved with a low-carbon building stone debris (BSD). Five dosages from coarse and fine soil-size ((BSDC) and (BSDF)) of BSD have been prepared to use in the EHPS-BSD mixtures. The laboratory tests included Atterberg limits, linear shrinkage, unconfined compression, consolidation, and swelling. The effect of the BSD on the time to zero-water content and the maximum swell was included. The efficiency of the BSD was proved by the amelioration of the compressibility and strength, and by reducing the shrinkage, swell pressure, and the potential of swelling. The shrinkage, compressibility, and swelling properties of the EHPS were reduced depending on the gradation and content of BSD. The gradation of BSD had a major role in strength development and controlling the time required to reach the final shrinkage and maximum swell stage.
