“…Detailed action plans are included in the 17 SDGs to end poverty and protect the planet by 2030, as shown in Figure 3. As shown, all aspects of social, economic, and environmental sustainability are considered so that an action in one area will affect outcomes in others [8]. Some of the 17 SDGs are clearly supported by geosynthetics, particularly in the environmental and economic categories, including goals such as clean water and sanitation, clean energy, infrastructures, and sustainable cities [8][9][10].…”

Geosynthetic engineering has made significant advances during the past decade in the areas of manufacturing and practical applications. As a result, geosynthetics have become essential materials that facilitate construction, better improve short- and long-term performance, and reduce long-term maintenance costs in routine civil engineering projects. Geosynthetics are also being recognized as fundamental to sustainable infrastructure development as they reduce the carbon footprint generated by infrastructure development by minimizing the use of natural construction materials. Creative use of geosynthetics in geo-engineering practices is expected to continue to expand as innovative materials and products are becoming available. In this paper, we begin by discussing issues related to climate change. The sustainable benefits of geosynthetics are then presented by demonstrating the potential of geosynthetics to significantly reduce carbon footprints compared to traditional solutions. Finally, recent geosynthetic technologies have been introduced for use in transportation infrastructure. The pathway forward of the geosynthetic technology is also discussed from the view of sustainable infrastructure development.

“…Table 2 below summarizes carbon emission resulting from construction of 1 m2 of both types of structurestypical and optimised. Embodied CO2 emission (eCO2)an equivalent measure of all GHG emissions related to production, transport and installation of material -values for each type of material were adopted from publications by Chappat and Bilal [11] and Raja et al [12]; some of the values had to be estimated as not all materials are discussed in these publications. In case of this project Pavement Optimisation reduced the carbon emission by about 8,4 kg (or 17%) of eCO2 per every square meter of the pavement.…”

There is a growing demand on reduction of greenhouse gases emission from all branches of industry. Roads construction is responsible for a substantial part of building industry carbon footprint. One of the ways to reduce its carbon footprint is the use of Pavement Optimisation (PO) with hexagonal geogrids technology. This technology utilizes the phenomenon of aggregate stabilisation by interlock within apertures of geogrid. When aggregate is placed and compacted on a layer of geogrid, a geogrid/aggregate composite – called Mechanically Stabilised Layer (MSL) - is created. Stiff geogrid ribs resist particle movement reducing layer deformation, which increases its stiffness. Increased stiffness of aggregate can be utilized in design, and has a substantial influence on pavement life. This provides the possibility to reduce the thickness of a pavement, including thickness of asphalt. Thinner pavement will require less materials, workforce, time and energy. It will be cheaper, and its construction will result in lesser emission of CO2. This paper presents the overview of Pavement Optimisation technology and results of full scale accelerated pavement tests confirming the influence of hexagonal geogrids. Case studies of projects with optimised pavements and calculations of carbon footprint savings achieved thanks to the use of PO are presented.

“…The past few years have seen an improved mastery of techniques of LCA in the field of geosynthetics. The latest calculations [44][45][46] are indicative of the progress made in this field, in which an ever-more constructed standard approach is evolving by using EC values representative of geosynthetics [47] and by comparing the EC values for entire construction solutions. Thus, results are recognized and trusted when the conclusion indicates that solutions using geosynthetics significantly reduce environmental impact.…”

Dykes, or levees, are structures designed and constructed to keep the water in a river within certain bounds in the event of a flood. In relation with climate change, more frequent floods, of higher intensity, can be expected due to anthropogenic emissions of greenhouse gases into the atmosphere. The objective of this review paper is to address the many ways in which geosynthetics contribute to sustainable construction of dykes and thus to water systems management. This review paper, prepared by the four Technical Committees and the Sustainability Committee of the International Geosynthetics Society, briefly describes geosynthetics and their function, dykes and dyke failure modes, before presenting the main focus of the use of geosynthetics for the design and construction of durable dykes to ensure the protection of life and infrastructure. The optimization of dyke construction with geosynthetics to increase their resilience not only results in performance advantages, but also in economic advantages. The way geosynthetics can contribute to mitigating greenhouse gas emissions for a sustainable river management is discussed. This is done not only by allowing more economic construction methods to be implemented, but also solutions with increased resilience to face the extreme stresses related to climate change, while at the same time bringing about a positive contribution to the reduction of greenhouse gas emissions during the construction process itself. Finally, it is shown that by following state of the art standards and design practice any possible risk associated with the use of geosynthetics in dykes can be mitigated.
