Research on Using Eggshells and Membranes for Calcium and Collagen Production Launched

Image author: No LBTU arhīva

Eggshells and membranes are usually considered waste, but they contain valuable substances that can be converted into high-value products. To explore this potential, a project has been launched in Latvia titled "Study of Eggshell and Egg Membrane Morphology and Their Industrial Use for Calcium and Collagen Production" (No. 25-00-C0LA1602-0000006). The goal of the project is to develop a sustainable technology for processing eggshells and membranes to produce high-quality calcium and collagen products.

The study will analyze eggshells’ morphology and chemical composition, assessing microbiological safety based on different pre-treatment methods. It will provide fundamental knowledge on Latvian eggshells and develop a scientifically grounded, economically viable method for their use in food or cosmetics.

Advanced technologies will separate shells from membranes, with analyses using microscopy, mass spectrometry, and spectroscopy. Shells will be converted into calcium carbonate and calcium salts, while membranes will provide collagen. This approach reduces food waste and creates sustainable, high-value raw materials for cosmetics, dietary supplements, and pharmaceuticals, supporting Latvia’s circular bioeconomy.

"Our goal is to show that valuable new products can be created from food waste. By applying scientifically proven methods and modern technologies, we can transform eggshells and membranes into innovative raw materials with wide applications in the food, cosmetics, and pharmaceutical industries. This project marks a significant step toward advancing a sustainable bioeconomy in Latvia," emphasizes the project leader, Dr.sc.ing. Vitalijs Radenkovs.

The project will run from August 1, 2025, to October 15, 2026, with a total budget of EUR 91,640.19, fully funded by the European Union. The leading partner is A/S Balticovo, with participation from the Latvian University of Life Sciences and Technologies (LBTU) and SIA Standel.
