“…In this regard, ES powder has potential as a mixed-type inhibitor with a predominant cathodic effect (Sannia et al, 2019). Furthermore, micronized ES powder has been exploited as an inert supplement, since partial cement replacement using ES powder produced concrete with a higher compressive modulus (Jhatial et al, 2019). In another application, ES powder was assessed as a fire retardant to produce fire-resistant cotton fabrics.…”

The eggshell (ES) provides protection against pathogenic and physical insults while supplying essential metabolic and nutritional needs for the growing avian embryo. It is constituted mainly of calcium carbonate arranged as calcite crystals. The global chicken egg production in 2018 was over 76.7 million metric tons. In industrialized countries, about 30% of eggs are processed at breaker plants that produce liquid egg products and large quantities of solid ES waste. ES waste is utilized for a variety of low-value applications, or alternatively is disposed in landfill with associated economic and environmental burdens. The number of patents pertaining to ES applications has increased dramatically in recent years; of 673 patents granted in the last century, 536 (80%) were published in the last two decades. This review provides a snapshot of the most recent patents published between 2015 and 2020, with emphasis on different biotechnological applications of ES waste, and summarizes applications for biomedical, chemical, engineering, and environmental technologies. Biomedical technologies include the production of calcium lactate, calcium phosphate, and health-promoting products, while chemical technologies include plant growth promoters, food processing and production, and biodiesel oil catalysis along with active calcium, carbon, soluble proteins, organic calcium, and ultrafine calcium carbonate sources. Engineering technologies address material engineering and nanoparticle production, while environmental technologies pertain to production of biomass, solubilization of sludge as well as production of magnetic ES adsorbents and adsorption of heavy metals, organics, total nitrogen and fluoride, soil pollutants, and radioactive compounds. Although the number of ES-based patents has exponentially increased in the last decade, exploration of innovative top-down approaches and ES development as a physical platform are new endeavors that are expected to further increase the upscaling of ES waste exploitation.

“…The continuous availability of eggshells in large amounts has inspired research on the utilization of this material in sustainable construction material development. Eggshell has been used as a mixing ingredient in the production of certain materials in civil engineering application [28]. Success in utilizing this material as partial sand replacement in concrete would have positive impacts on the environment.…”

The excessive extraction of sand from riverbeds has adverse effects on river ecosystems and aquatic life. Simultaneously, the disposal of eggshells from certain food manufacturing facilities into landfills contributes to pollution. Incorporating crushed eggshells as a partial replacement for sand in concrete can reduce the demand for natural sand, thus decreasing the need for sand mining from rivers. The present research investigates the effect of crushed eggshells as partial sand replacement on workability, compressive strength, and splitting tensile strength of concrete. Five different concrete mixtures were tested, with crushed eggshells replacing sand at percentages ranging from 0% to 20% by weight. All specimens underwent water curing and were subjected to three tests: slump, compressive strength, and splitting tensile strength. The incorporation of eggshells, finer than sand, reduced workability but showed acceptable strength up to a 10% replacement rate. In conclusion, using eggshells as a sand substitute in concrete production can contribute to a cleaner environment and support river ecosystem sustainability.

“…Therefore, there is an urgent need to identify new alternative materials that can replace the traditionally used virgin materials in CEM-II-based concretes, which have longevity in supply and serve as a sustainable solution for reducing both GHG emissions and energy consumption in concrete production. Over the past three decades, the replacement of Portland cements in concrete has gained widespread research interest across the globe [5][6][7][8][9][10][11][12]. Industrial waste materials such as pulverised fly ash (PFA), ground granulated blast furnace slag (GGBS), glass powder amongst other pozzolanic materials have been extensively assessed as partial replacements [4,9,10].…”
