Impact of type of housing on waste recycling - case study of the Písek region
VACKOVÁ, Jana
My thesis aims to clarify issues regarding waste sorting and the willingness of the population according to the type of their residence to sort waste. The theoretical part focuses on waste management in the Czech Republic and neighbouring countries. The main objective was to describe the waste management in the Písek region. I concentrated on the description of particular technologies, especially recycling. Another chapter describes the relationship of the population to waste sorting, as human behaviour and lifestyle are the main causes of environmental damage. Recycling may be the right way to decrease the negative impact of human society on the environment. The practical part presents the results of the quantitative research conducted by means of a questionnaire. According to the respondents´ answers, I was able to conclude the differences of waste separation between the town and village. From the total of 247 respondents, 80 % sort the waste, 16 % sometimes sort it, and 4 % never do so. The categories of respondents differ in the amount of waste sorting, however, the difference is not statistically significant (Chi Squared test = 2,075; s. v. = 4; p = 0,722). Depending on the type of residence, the highest percentage 87 % - of waste sorting occurs in the housing estate category and zero percentage of respondents in this category never sorts. I was also concerned with the difference in the degree of sorting of individual commodities depending on the type of residence. It is significant only in the amount of sorting hazardous waste (Chi Squared test = 18,5; s. v. = 4; p = 0,001). In the case of other commodities, the type of residence does not affect the amount of their separation. It is obvious that the type of build-up area affects the way of life of the population and thus the amount of waste they produce. In general, the degree of diversity in respondents´ waste sorting depends on their education, experience, life priorities and public awareness of waste management.

Toy or Toxic Waste?: Our study is a continuation of the investigations of IPEN and Arnika that found octaBDE, decaBDE and HBCD in Rubik's cubes, children's toys and hair accessories, i.e., products that were not treated with these substances but made of recycled plastic.
Petrlík, Jindřich ; Straková, Jitka
Our study is a continuation of the investigations of IPEN and Arnika that found octaBDE, decaBDE and HBCD in Rubik's cubes, children's toys and hair accessories, i.e., products that were not treated with these substances but made of recycled plastic. The previous study indicates that banned brominated flame retardants commonly found in hazardous electronic and building waste are recycled into new products where they were not present historically. We conducted additional sampling to further examine whether toxic substances are being recycled into children’s toys on the Czech market.

Health Risk Assessment of Selected Factors of Working Environment and Occupational Health Services in the Field of Recycling and Processing of Secondary Raw Materials and Waste
DVOŘÁKOVÁ, Sára
This thesis deals with the evaluation of health risks of chosen factors in the work environment and medical services in the recycling and secondary raw materials and waste processing field. The goal of the thesis is to chart companies which handle recycling and secondary raw materials and waste processing in the South Bohemian Region, to find out the risk factors that go in hand with this work and to determine in which work category these workers belong. I have determined three hypotheses within the research. Hypothesis 1: The nature of the work activities does not correspond with suggested risks. Hypothesis 2: The workers are not equipped with tools in accordance with detected risks. Hypothesis 3: The workers of companies dealing with recycling and secondary raw materials and waste processing do not attend the necessary medical check-ups. The thesis consists of a theoretical and a practical part. In the theoretical part I have introduced the risk factors connected to recycling and secondary raw materials and waste processing. I have covered the problematics of medical services for the employees, occupational disease and the protection of health from unfavorable effects of the work environment. To reach my goal, I have utilized quantitative research methods. For data collecting I have used anonymous surveys in the area of the South Bohemian Region. In the survey, I have adressed scrapyards, composting plants, collection yards and waste dumps. The collected data were processed by the Microsoft Excel program. The obtained data may be used as an information source for students as well as for employers and employees in companies handling secondary raw materials and waste processing.

Zhodnocení možností využití stavebních recyklátů do konstrukčních vrstev železničního spodku
Bělunek, Jakub
This thesis deals with recycled construction materials used in the structural layers of rail track substructure. The thesis describes the construction of rail track substructure, current situation in recycling of aggregates, waste management, the impact of railway structure on the environment, sampling and uncleaned rail track ballast. At the end of the theoretical part is the chapter Recycling of aggregates of the railway track bed. In the practical part, is provided the specification of properties recycled construction materials which are produced in selected facility and an assessment of the established facts. First, the selected facility is characterized. Next, the technical and environmental requirements are described and then the tests of physical properties to conclusiveness quality of recycled construction materials are defined. To evaluate the possibilities of utilization is performed long-term monitoring of physical properties and then are individual results overall are valorized. Finally, the practical recommendations are formulated.
