“…Rahayu and Hanifa (2017) have shown that eggshells can increase growth and facilitate digestion in piglets by mixing in pig food. Habeeb et al (2014) have investigated the benefits of eggshells that can be used for alternative cement materials. The same thing has also been revealed by Dapas (2020), Nandhini and Karthikeyan (2021) and Sathiparan (2021) that the high content of calcium carbonate in eggshells when powdered can be used as a substitute for Portland cement which has calcium carbonate as the main element (55-60%).…”

Eggshell waste and husk ash are abundant in Indonesia, with a population of 263 million, which is estimated to reach 483,920 tons and 10 million tons, respectively. However, this waste has not been utilized optimally, so it has a negative impact on the environment. This study aims to analyze the quality (compressive strength and water absorption) of a mixture of eggshells and husk ash as paving blocks for buildings to reduce the environmental burden. The experiment was carried out using a 2 factor factorial design: eggshells (4 levels: 0%, 5%, 7% and 15%); and husk ash (4 levels: 0%, 5%, 8% and 10%). The data were analyzed using analysis of variance, followed by analysis of mean using the least significant difference (LSD). The results showed that the mixture of eggs and husk ash had good quality, so it could reduce the need for Portland cement, which has a negative impact on the environment during production process. The best quality of a paving block was a mixture of 10% of husk ash and 15% of eggshells (A4B4 treatment) with the compressive strength value of 39 Mpa and water absorption of 5.8% (good).

“…From the application of the calcined eggshell in the treatment of real electroplating wastewater, the calcined eggshell showed a promising removal capacity of heavy metal ions as well as it had a good neutralization capacity in the treatment of strong acidic wastewater. Habeeb et al 2014 evaluated the characterization and application of chicken eggshell as green and economical adsorbents for the treatment of hydrogen sulfide from wastewaters, which is fatal to benthic aquatic lives as it depletes the dissolved oxygen in their ecosystem. The results showed that the calcinate waste eggshell had the highest adsorption capacity.…”

Eggshell is a solid waste, with production of several tons per day. Eggshell is mostly sent to the landfill with a high management cost. It is economical to transform the eggshell waste to create new values from these waste materials. The present article is an attempt to summarize the possible applications of eggshell. The eggshell waste can be used (a) at biodiesel production as a solid base catalyst used for biodiesel pollutants minimization, reducing the production costs of biodiesel and making the process of biodiesel production fully ecological and environment-friendly; (b) as an absorbent of heavy metals from wastewater as it is a serious environmental problem in the ecosystem; (c) as biomaterial in order to replace bone tissues due to the rise in the number of patients; (d) as a fertilizer and calcium supplement in nutrition for human, animals, plants, etc. Number of research articles have been included in this review to describe a methodical growth in this subject matter.

Background The Environmental Protection Agency has listed eggshell waste as the 15th most significant food industry pollution hazard. Using eggshell waste as a renewable energy source has been a hot topic recently. Therefore, finding a sustainable solution for the recycling and valorization of eggshell waste by investigating its potential to produce acid phosphatase (ACP) and organic acids by the newly-discovered B. sonorensis was the target of the current investigation. Results Drawing on both molecular and morphological characterizations, the most potent ACP-producing B. sonorensis strain ACP2, was identified as a local bacterial strain obtained from the effluent of the paper and pulp industries. The use of consecutive statistical experimental approaches of Plackett–Burman Design (PBD) and Orthogonal Central Composite Design (OCCD), followed by pH-uncontrolled cultivation conditions in a 7 L bench-top bioreactor, revealed an innovative medium formulation that substantially improved ACP production, reaching 216 U L−1 with an ACP yield coefficient Yp/x of 18.2 and a specific growth rate (µ) of 0.1 h−1. The metals Ag+, Sn+, and Cr+ were the most efficiently released from eggshells during the solubilization process by B. sonorensis. The uncontrolled pH culture condition is the most suitable and favoured setting for improving ACP and organic acids production. Quantitative and qualitative analyses of the produced organic acids were carried out using liquid chromatography-tandem mass spectrometry (LC–MS/MS). Lactic acid, citric acid, and hydroxybenzoic acid isomer were the most common organic acids produced throughout the cultivation process. The findings of TGA, DSC, SEM, EDS, FTIR, and XRD analysis emphasize the significant influence of organic acids and ACP activity on the solubilization of eggshell particles. Conclusions This study emphasized robust microbial engineering approaches for the large-scale production of a newly discovered acid phosphatase, accompanied by organic acids production from B. sonorensis. The biovalorization of the eggshell waste and the production of cost-effective ACP and organic acids were integrated into the current study, and this was done through the implementation of a unique and innovative medium formulation design for eggshell waste management, as well as scaling up ACP production on a bench-top scale.
