Possibilities of using recycled concrete as fine aggregate replacement in cement screeds
Nováková, Iveta ; Brožovský,, jiří (referee) ; Hubáček, Adam (advisor)
The bachelor thesis deals with summary of knowledge about cement-based screed with partial replacement of natural aggregates by recycled aggregates. Special emphasis is given to describing and studying characteristics of cement-based flowscreed. In this study are described feedstocks with requirements which they must meet and test methods for testing properties of screeds. One part is also given to practical application of cement-based flowscreed with partial replacement of natural aggregates by recycled aggregates.

Best available techniques for construction and demolition waste treatment
Keprtová, Karolína ; Kolář, Jan
Waste prevention is the best approach according to the waste hierarchy, but there are activities which can‘t avoid waste production. Such activities include construction activities, in particular demolition and landscaping. If waste is generated, its recycling is desirable. Recycling installations should be beneficial to the environment and should therefore meet high environmental standards. For this purpose are BAT (Best Available Techniques) widely used. The paper summarizes the possibilities of using BAT for recycling construction and demolition waste.

BAT Use Treating and Recycling Construction and Demolition Waste
Keprtová, Karolína ; Kolář, Jan
Prevention of waste production is a priority according to a Czech legislation. In cases such as demolition, when the generation of waste cannot be prevented, is desirable to use the material. The material recovery of demolition waste requires technical and technological equipment at the appropriate level, which is very expensive. To obtain the necessary equipment it is possible to use, for example, the grant calls that support new technologies, applying the principles of circular economy and environmental friendliness. For the assessment of environmental friendliness it is possible to compare a particular technique with the best available technique (BAT, Best Available Techniques). Technology, which comply with BAT aspects, ensure compliance with both legislative and performance requirements for a number of years to come while guaranteeing sufficient capacity to recover waste to create valuable and recyclable products.

Construction and demolition waste
Šmídová, Denisa ; Výskala, Miloslav (referee) ; Aigel, Petr (advisor)
This bachelor thesis deals with the analysis of the amount of construction and demolition waste on two-storey flat-roofed houses. It is based on legislation that comes into force this year. The data processing methodology proposes a procedure to determine the amount of demolition waste on a construction site. The breakdown of waste types is proposed according to the expected acceptance of this waste in recycling centres or landfills. The budget for the new construction of the building is used to analyse this quantity. The identified quantity of construction and demolition waste is related to the floor area and the built-up area of the building. The analysis of the amount of waste in the demolition of a building is complemented by a practical example, including a comparison of the current methodology.

Legal regulation of construction waste management in the context of the circular economy
Prucek, Jan ; Sobotka, Michal (advisor) ; Fabšíková, Tereza (referee)
The thesis deals with the legal regulation of construction and demolition waste as a specific group of waste, especially with regard to its placement in the context of the concept of circular economy. In addition to the current state of this topic, the historical development of the legislation is presented, as well as the individual methods of construction waste management and related institutes and entities governed by this legislation are defined. The thesis has an introduction, four chapters, each of which presents the individual topics in detail, and a conclusion. The first chapter introduces the concept of circular economy, its development and legal anchorage, as well as its basic principles. The chapter also defines the concept of waste management, going beyond this to present its hierarchy and basic objectives. The second chapter analyses the development of waste legislation with a focus on construction and demolition waste and in addition presents the strategic documents of waste management, which are the Waste Management Plans. The third chapter is devoted to the object and entities of the legislation, i.e. construction and demolition waste, and waste in general, and the persons involved in waste management. For construction and demolition waste, the emphasis is on its definition and...

Využití odpadů při výstavbě pozemních staveb
ŠIRMEROVÁ, Karolína
This thesis focuses on utilization of waste during buildings construction. The first part of the thesis encompasses a literature search that describes basic information about waste, such as types of waste and its origination. Further, it describes the EU Protocol regarding handling of construction and demolition was-te, waste utilization during construction, problematics of hazardous waste, and han-dling of waste in EU countries. For interest, included is also a description of houses built from waste materials, eg. Earthship. The second half focuses on practical aspects. It includes information about a selected section of highway D3, the process of construction of highway D3, and the proposal for utilization of recycled materials in highway components. Next, are calculations and information about availability of recycled materials.

The Benefit of the Waste Management
Marek, Martin
This article aims to highlight the importance of construction demolition waste management. The emphasis is on fulfilling the principle of circular economy. CDW is the largest mass flow of waste in the EU, which is why the EU is gradually introducing measures to reduce construction waste production. The article analyzes data from the CZSO and EUROSTAT on waste production, which allow to compare separately branches of construction production: building construction, civil engineering and specialized construction. The data will be compared with national economic performance indicators. By comparing the size of CDW production with GDP, the degree of their interdependence will be determined. The aim of the analysis is to assess the link between the GDP of the country and the production of CDW.
