Environmental Impact Assessment for Powder Coating Technology
Havlíček, Lukáš ; Mukhametzianova, Leisan (referee) ; Krbalová, Maria (advisor)
This diploma thesis is focused on evaluating an environmental impact of using LCA methodology. LCA is a methodology of powder varnishing. The first part of the thesis is concerned with technologies modifying metal surfaces. An analysis of LCA technology was executed and a technological process was described. As a part of theoretical part, a description of available methods evaluating environmental impact was made. According to description the LCA methodology was chosen. In practical part of the thesis an analysis of material and energetic inputs of each process was made.

Assesment of the Environmental Impact in the Design of Production Machines in Terms of Greenhouse Gas Emissions of Selected
Krbalová, Maria ; Pačaiová,, Hana (referee) ; Demeč, Peter (referee) ; Blecha, Petr (advisor)
The presented doctoral thesis is focused on environmental impact assessment of basic engineering materials used in a production machine construction. Ecological profile of the machine itself develops already in the phase of its design. It is not only about the choice of future machine parameters and materials that it is built from, but also about technologies used for its manufacture and operation conditions of the finished machine (consumption of energy and service fluids). The thesis occupies in detail with environmental impact analysis of the production machine design from the viewpoint of material production that mentioned machine consists of. The output from the performed analysis is methodology for evaluating of machine design from the viewpoint of greenhouse gas emissions. Created methodology enables evaluating of machine ecological profile and its possible adjustments even during pre-production stage. In the first part of the thesis the analysis of current legislation in the field of fighting against climate changes, reducing of products energy consumption and increasing of production machines energy efficiency is presented. Also in this part of the thesis description of methods that were used to achieve thesis goals is stated. Furthermore analysis of production machine as a system of structural components that fulfil the certain functions and description of used basic engineering materials are presented. The second part of the thesis is devoted to environmental impact analysis of the production machine design process. There the design process and environmental impact of machine design are described. This is followed by description of production machine life cycle and detailed analysis of undesirable substances emissions emitted during pre-production phases of machine life cycle (i.e. during the raw materials extraction and materials production). From this analysis the particular constituents’ pre-production phases which are sources of undesirable substances emissions (e.g. greenhouse gas emissions) were derived. The thesis also includes analysis of these constituents’ life cycles and description of electric power generation as a basic constituent of any phase of product life cycle. In this part of the thesis calculations of particular fuel type’s amounts that is required to produce 1 MWh of electric power and carbon dioxide amount produced during electric power generation are presented. The third part of the thesis contains created models of manufacturing processes of basic engineering materials and calculations of related emissions of selected greenhouse gases. The practical output from this part of the thesis is methodology that enables environmental impact assessment of machine design from the viewpoint of engineering materials used in its construction.

Implementation of selected environmental management system elements according to ISO 14001 in company
Bartolšic, Jan ; Kotek, Luboš (referee) ; Krbalová, Maria (advisor)
This diploma thesis deals with creation of environmental management system according to standard ISO 14001:2016 in a manufacturing plant. The theoretical part of the thesis describes the development of ecology worldwide, including its relation to industry, mandatory legislative requirements for an enterprise with the aspect of environmental protection, description of the systems EMAS and ISO 14001: 2016 and the comparison of their requirements. Finally, the theoretical part includes the introduction of the company in which the practical part of the work was implemented. The practical part of the thesis describes the requirements of individual chapters of ISO 14001: 2016 and they are compared with the actual state of company. Subsequently, the author of the thesis created all required documentation for the missing parts of the standard (e.g. environmental policy, environmental aspects, binding obligations of the company and others). This documentation should be implemented by the company in all its departments for successful certification according to ISO 14001: 2016.

Environmental Impact Assessment by Machinery Products/Processes
Navrátilová, Jana ; Rozehnalová, Jana (referee) ; Krbalová, Maria (advisor)
This Diploma thesis is focused on the assessment of environmental load of a bottle crown cork. The theoretical part describes the current global environmental problems and a chosen environmental legislation, which may also apply to engineering companies. In thesis is included the description of a various methodologies for assessing the environmental load, from which was a method LCA (product life cycle assessment) for solving the problem chosen. The thesis describes the crown cork and its production. In practical part is made the environmental load evaluation of this product. Three variants of the crown cork are selected, whose life cycles are simulated and analysed. The results of the variants are afterwards compared.

Environmental Impact Assessment for Chosen product
Durda, Tomáš ; Řezníčková, Hana (referee) ; Krbalová, Maria (advisor)
The Master´s thesis is structurally divided into the theoretical and practical part. In the theoretical part, the author describes current global environmental issues and the impact of the industry on the environment. The current state of the environmental legislation in mechanical engineering, environmental management systems, and methodologies of an environmental impact assessment are described. The practical part deals with the environmental burden of the snowboard production process according to the LCA method. Life cycle inventory is performed to evaluate individual materials whose production is the most environmentally damaging. At the last stage, possible measures are proposed to reduce the environmental burden.

Placing Engineering Products on Market in the European Union
Vývodová, Veronika ; Řezníčková, Hana (referee) ; Krbalová, Maria (advisor)
This bachelor’s thesis concerns placing machinery products on market in the European Union, and summarizes the steps necessary for placing those products on the European market. The theoretical part summarizes the legislative requirements by the European Union, including the Czech Republic, which manufacturers must follow. The practical part applies findings to particular machinery, but is primarily focused on the identification of hazards and system risk analysis of a table drill. The practical part also includes an elaboration on the declaration of conformity.
