Adding value to waste material - eggshells
Zlámal, Filip ; Pernica, Marek (referee) ; Brummer, Vladimír (advisor)
The submitted thesis deals with the utilization of waste materiál – eggshells and the evaluation of this waste raw material to obtain interesting and valuable products. In the introduction of the thesis are described properties, composition and structure of the eggshell rich in minerals and the composition of its membranes. In the next part of the thesis is evaluated potential utilization of this waste as a fertilizer, adsorbent, possible uses in medicine and pharmacy, utilization in electronics, as a catalyst in the production of biodiesel and its further uses.

Treatment of bilogical waste from egg processing
Zich, Jan ; Brummer, Vladimír (referee) ; Máša, Vítězslav (advisor)
The main target of this final thesis is to compile possible uses of eggshell waste with emphasis on pharmaceutical industry. Firstly, the common handling of this waste, including legislation, is described. It is also explained what eggshell waste is mainly composed of – eggshell containing calcium and eggshell membrane rich on collagen and other substances. In addition, various ways of using eggshell waste are presented and evaluated, including manufacture of pharmaceutical products. Finally, a search for commercial solutions, patents and other sources dealing with the process of processing egg waste is carried out. It showed that although there are many patents, the offer of equipment for this purpose is very limited on the market. The acquired knowledge is used in the design of a unique process line enabling processing of both components of eggshell waste as pharmaceutical products.

Doležalová, Eliška
Eggs are now recognised not only as a dietary ingredient but also as a starting material providing many valuable bioactive compounds that are used primarily in food processing but also in medicine, veterinary medicine, pharmacology and biotechnology. Egg yolk is an important source of antioxidants, aromatic amino acids, carotenoids, vitamins, phospholipids and proteins. Egg white is an excellent natural source of high quality protein that is rich in essential amino acids. Eggshell mainly contains calcium and other minerals. Hen egg yolk has a number of technological functions, including emulsifying, gelling and film-forming. Different types of modification can be used to improve the functional properties of egg components. For example, enzymatic hydrolysis can be used to modify the egg yolk and deamidation is used to modify the egg white. Eggshells are primarily considered as zero-value waste, although they are rich in organic and inorganic compounds that can be used in various forms.
