“…Furthermore, durability indexes under wet-dry cycles were placed in the permissible range. It is also notable that biopolymer treated soil is capable of enhancing the heavy metal attenuation capacity of the soil, causing less harmful leachate containing heavy metal to pass through the soil to groundwater [143]. Therefore, with the great potential of biopolymer-treated soil in landfill application, further use of biopolymers in research and practical applications is expected in the future.…”

Soil improvement using biopolymers has attracted considerable attention in recent years, with the aim to reduce the harmful environmental effects of traditional materials, such as cement. This paper aims to provide a review on the environmental assessment of using biopolymers as binders in soil improvement, biopolymer-treated soil characteristics, as well as the most important factors affecting the behavior of the treated soil. In more detail, environmental benefits and concerns about the use of biopolymers in soil improvement as well as biopolymer–soil interaction are discussed. Various geotechnical properties are evaluated and compared, including the unconfined compressive strength, shear strength, erosion resistance, physical properties, and durability of biopolymer-treated soils. The influential factors and soil and environmental conditions affecting various geotechnical characteristics of biopolymer-treated soils are also discussed. These factors include biopolymer concentration in the biopolymer–soil mixture, moisture condition, temperature, and dehydration time. Potential opportunities for biopolymers in geotechnical engineering and the challenges are also presented.

“…Such properties also put them in the center of attention for soil investigations. Xanthan with microbial source, guar, taragacanth and ghatti with plant origin, sodium alginate and agar as sea weed gums are examples of natural gums' application in soil environment with the purpose of erosion reduction and mechanical behavior improvement (Ayeldeen et Kumar et al 2021). The enhanced mechanical and physical properties of the soil caused by hydrocolloids on one hand and the increasing global need for renewable and green materials on the other hand have encouraged investigators to seek new sources of hydrocolloids as soil stabilizers.…”
