Applying a Systems Thinking Approach to Circular Economy Transitions: Insights From the Use of a Sociotechnical Systems Approach Within the UK Hospitality Sector

Business Strategy and the Environment, EarlyView.
ABSTRACT Despite more than 20 years of research into sustainable tourism, the environmental impact of the UK hospitality sector remains high. A growing body of research into the concept of a circular economy (CE) demonstrates that transitioning to this way of working has significant benefits both for the environment and business outcomes.

A Review Study of Eggshell Powder as Cement Replacement in Concrete

SULAIMANI JOURNAL FOR ENGINEERING SCIENCES, 2022
The extensive usage of cement concrete leads to a 5% to 7% release of Carbon Dioxide (CO2) gas into the atmosphere resulting in increased global warming. Also, the increase in world population and industry has led to the generation of by-product waste materials such as eggshells.

Microemulsion‐Based Drilling Fluids Incorporating Seashell Residue Powder: A Sustainable Approach to Fluid Loss Control

Journal of Surfactants and Detergents, EarlyView.
Two microemulsion‐based drilling fluids incorporating SSRP were formulated using pine oil, the nonionic surfactant Alkonat L100W, and a glycerol/water solution. The results provide valuable insights into how surfactant‐assisted microemulsion systems can be engineered to enhance the performance and eco‐efficiency of drilling fluids.

Improvement of water absorption behavior and mechanical properties of woven jute fiber‐reinforced epoxy composites with waste eggshell filler

Polymer International, EarlyView.
This study investigates the influence of waste eggshell powder on the water absorption and mechanical properties of jute fiber‐reinforced epoxy composites. Optimal eggshell filler content (2 wt%) significantly enhances composite performance by reducing water absorption and improving mechanical properties.

Experimental Evidence for Mobilization of Mercury From the Eggshell by the Developing Embryo in an Avian Model Organism

Environmental Toxicology, EarlyView.
ABSTRACT Of the many pollutants wildlife is exposed to, mercury ranks among the most toxic. In birds, mercury does not only accumulate within generations, but also is transferred across generations via maternal offloading in eggs, with higher mercury concentrations found in shells of unhatched eggs.

Procurement of Senonian Flint for Bladelets Production at the Early PPNB Site of Nahal Zahal in the Northern Negev Established for the First Time Using Chemical Composition Analysis

Archaeometry, EarlyView.
ABSTRACT The hypotheses of Senonian flint to be a prime source of prehistoric “chalcedony” flint artefacts from the Negev Desert (Israel) was not investigated in detail thus far. By combining trace‐element profiling with statistical interpretation, ten flint items from Nahal Zahal, an Early Pre‐Pottery Neolithic B site in the northern Negev, were ...

A novel air-polishing powder from natural eggshell

Journal of Oral Science
This study compares the ability of extrinsic stain removal and surface roughness changes on tooth surfaces after using two different types of dental air polishing powder: Sodium bicarbonate and novel eggshell powder.For the study of extrinsic stain removal, twenty bovine teeth were soaked in coffee for extrinsic stain formation.

Spectromicroscopy Analysis of Chicken Egg Shells

X-Ray Spectrometry, Volume 55, Issue 4, Page 587-596, July/August 2026.
ABSTRACT Chicken egg shells, taken from farm and backyard eggs of different suppliers from different regions in Brazil were collected for chemical/structural analysis, in order to try to find if there is a relation between egg shells composition and the type of production (farm or backyard), the egg shell color and the region of production.

Sustainable Glass Foams From Recycled Glass and Rice Husk Ash: Thermal Insulation Performance for Ceiling Applications

International Journal of Applied Glass Science, Volume 17, Issue 3, July 2026.
Glass foams were produced using recycled glass and rice husk ash as raw materials. After deep characterization, miniature masonry model tests demonstrated effective thermal insulation when applied as a ceiling lining. The study validates the technical and environmental feasibility of glass foams for sustainable insulating materials in building ...
