“…[17,19,20,32,33] As such, our coating showed the lowest oxygen permeability when compared to other coatings (Figure 4a) and limits the gas transmission better than other coatings. [17,19,20,32,33] In addition to the gas permeability properties, the ability of the coating to prevent water loss is also important as it contributes to the overall weight loss of the egg. The water vapor transmission rate (WVTR) for our coating was measured to be an average of 31.5 ± 9.0 g mm m −2 per day.…”

Egg waste is a major contributor to global food waste, accounting for 15% of discarded food in the United States. Typically, eggs have a shorter shelf life at room temperature and are preserved in refrigeration from production to consumption. However, maintaining constant refrigeration is energy‐intensive and expensive. Here, a bionanocomposite coating has been developed that incorporates each element of eggs – egg white, yolk, and eggshell – to increase the shelf life of fresh eggs without requiring further refrigeration. The quality of eggs has been successfully preserved for up to three weeks at room temperature. The coated eggs maintain the highest grade (AA) and exhibit improved Haugh Unit (HU), Yolk Index (YI), and pH compared to uncoated eggs. The coating reduces weight loss by ≈37% with an increase in HU (≈12.5%) and YI (≈13.9%). Morphological analysis reveals strong adhesion of the coating to the eggshell surface, showcasing promising barrier properties. The coating demonstrates an optimal combination of oxygen permeability (≈12.2 cm3 µm m−2 d−1 kPa−1) and water vapor transmission (≈31.5 g mm m−2 per day) with excellent antimicrobial properties. Overall, this approach of repurposing eggs into a high‐performance coating shows a promising viable alternative to refrigeration and a solution to combat egg waste.

“…Although the global market price of XG substantially decreased during recent decades and is currently USD3=kg on average (Chang et al 2015b(Chang et al , 2016bYegin et al 2017), the material cost of XG for a unit weight (1 ton) of local soil treatment is still more expensive than C8F2 and C6F4 binders. However, the life-cycle cost of XG treatment may be lower than that of cement treatment due to fewer concerns relating to demolition waste of biopolymer-treated soils according to the biodegradability of biopolymers (Niaounakis 2013;Plackett 2011). Moreover, although XG is biodegradable, several studies suggest that this occurs very slowly (Hovland 2015;Liu et al 2005;Ruijssenaars et al 1999) and indicate sufficient strength durability against severe repetitive wetting and drying processes (Chang et al 2017;Qureshi et al 2017).…”

Currently, soil stabilization is used in road construction in Sri Lanka, especially for soft road shoulders. The socioeconomic demand for sustainable development has raised the necessity of new environmentally friendly soil binders for construction engineering practices, including road construction. Industrial residues such as fly and bottom ashes are commonly used to reduce the amount of cement in concrete mixtures or soil stabilization practices, and new biological materials and methods have been introduced by a number of studies to improve the strength of soils without the use of chemical binders such as cement. Among others, microbial-induced biopolymers have been experimented with as a new binder material for soil treatment due to their high strengthening efficiency and low environmental impact. This study verified the feasibility of biopolymer application on local soil stabilization, specifically for road shoulder construction in Sri Lanka, by comparing the unconfined compressive strength (UCS) of local soil samples treated with cement-ash-based binders and xanthan gum biopolymer. The xanthan gum biopolymer-treated condition had significant UCS strengthening and high ductility compared with other treated conditions. Thus, xanthan gum biopolymer shows promising potential as an alternative material for road construction (particularly for shoulders and subbases) in Sri Lanka and in other nations with similar climates and socioeconomic conditions.

Recently, there has been renews interest in chitosan as materials in producing of biocomposite films. The chitosan (CS)/corn cob (CC) biocomposite films were prepared by solvent casting method. The effect of CC content on tensile properties of CS/CC biocomposite films was studied. The tensile strength and elongation at break of CS/CC biocomposite films decreased as increasing of CC content. However, the increasing of CC content was increased the tensile modulus of CS/CC biocomposite films. Scanning electron microscopy (SEM) was indicated that the deceasing of tensile properties was due to the poor interfacial adhesion between CC filler and CS matrix.
