Effective use of industrial waste in building materials
Szép, Melinda Klaudia Virág ; Mészárosová, Lenka (referee) ; Černý, Vít (advisor)
This bachelor´s thesis deals with one of current topics, namely to effective use of industrial waste in building materials. The theoretical part of this work presents changes in legislation of the Czech Republic in field of waste management system, explains the most important terms and defines each method of waste management. The main goal of this work was to formulate a methodological procedure for efficient use of industrial waste. The methodological procedure was compiled on the basis of elaborated base set of possible variants of waste utilization in the construction sector and a set of corresponding criteria of standards and legislative criteria. A table of elementary criteria has also been compiled for the better orientation in corresponding standards. The proposed methodological procedure was demonstrated on specific example, in fact on slag from municipal waste incineration. The slag was examined in two environments – one with standard laboratory condition and the second with controlled condition (8 % concentration of carbon dioxide and 80 % of relative humidity) – for better understanding of its behaviour. The expected acceleration of the aging process in the environment with controlled condition was confirmed based on the degree of carbonation. The expected reduction of volume changes of the sample exposed to the controlled condition was also confirmed.

Magnetic separator
Křupka, Jiří ; Jonák, Martin (referee) ; Malášek, Jiří (advisor)
The aim of this bachelor thesis is to design the structural conception of magnetic separator designated to separate small-sized industrial waste. This report provides an overview of facilities of worldwide manufacturers that are used for magnetic separation of steel scrap. Furthermore, it offers an assessment of variants for technical solutions to structural nodes of magnetic separator; this is followed by a selection of specific solution. According to the input parameters, all the parameters necessary for correct machine design are computed. These computations also include the justification of selected table values, placement, surface roughness, geometric tolerances, materials and heat treatment of the individual parts and assemblies. Attachments to this technical report are documentation drawings of selected parts and assemblies.

Elastomer fillers as a potential raw material for concrete and mortar products
Jankech, Filip ; Balog, Oliver (referee) ; Bodnárová, Lenka (advisor)
To attain a sustainable development in the field of building materials, it is necessary to consider environmental, economic, and social aspects of the industrial production. This thesis addresses the first two aspects. Both theoretical and practical research were implemented in order to study the possibility to replace the commonly used RDPs, that are being used in the dry-mix mortar industry as a primary additive, with the industrially processed elastomer waste materials, such as recycled tire rubber. The review of the scientific literature processed within the theoretical research discloses the state of the art in the field of polymer modification of the mortar products and the effect of the commonly used modifiers and elastomer fillers on the performance of mortar and concrete products. The experimental research was implemented to study the possibility of the replacement of the RDPs for the elastomer fillers. The performance of fresh and hardened mortar containing various amounts of elastomer particles was studied. The results indicate, that the partial replacement could be feasible without worsening the performance of the product.

Influence of Waste Diatomite as a Raw Material on the Properties of the Inorganic Foam Glass
Nguyen, Martin ; Sedlačík, Martin ; Sokolář, Radomír ; Opravil, Tomáš
This article deals with the manufacturing process of inorganic foam glass with utilization of waste diatomite as a raw material. The waste diatomite was first subjected to an analysis of chemical and mineralogical composition. The foam glass was formed by a powder sintering method by pressing into pellets with the addition of a foaming agent. After firing, the properties of the foam glass were investigated using an X-ray diffraction analysis, scanning electron microscopy, bulk density, and compressive strength. The possibility of utilization of waste diatomite in raw material mixtures was investigated in accordance with the influence of firing temperature and the resulting properties of inorganic foam glass.

Analýza produkce a nakládání s odpady vznikajícími ve vybraném podniku
Groman, Martin
The objective of the bachelor work is the analysis of waste production and waste treatment in the industrial company Česká zbrojovka a.s. Within the introduction part I have specialized on legislation of the Czech Republic in the area of waste management, mainly for stated industrial company Česká zbrojovka a.s. Furthermore, I have described the company and her environmental policy. Within the following part I have stated the origin of industry waste, manipulation, management and disposal of the waste produced by the company. In the conclusion I have proposed suggestions for waste decreasing, improvement of the company ecology and Česká zbrojovka a.s. environmental impact empowerment.

Analýza systému nakládání s odpady ve firmě OSMONT,s.r.o.
Homola, Lukáš
The diploma thesis is focused on OSMONT s.r.o.'s waste management system analysis. Basic terms related to valid legal and normative regulations in the area of waste management are characterised within the paper. Under the thesis assignment, waste type and composition is specified, reflecting the production process of the company. The paper also mentions operation and running specifics of production processes within the business entity. Based on the waste management analysis, an evaluation of the current system was conducted. In conclusion, practical recommendations for changes and improvement of the current waste disposal system in OSMONT s.r.o. were proposed.
