Thesis is focused on the issue of waste production, collection and management in Excalibur Army, s.r.o company, at the facility in Šternberk. I have used registration and operative data acquired directly in cooperation with the service ecologist. I described the process of waste management at the facility, since its creation until its application as a secondary raw material or its transfer to the authorized personnel for its disposal either to deposition in land-fill or its combustion in the incinerator. In my conclusion, I suggest several operational, but also administrative, precautions for overall improvement of waste management in the company.

The Kingdom of Saudi Arabia is the largest country in the golf states and one of the richest oil producing countries. Saudi population is nearly 27million; in addition, Saudi Arabia receives millions of people from around the world for Islamic pilgrimages. Moreover, Saudi is hosting hundreds of thousands of international professionals and labourers. Hence, the country infrastructure and services have been in the top agenda to be modernized in order to cope with new demand for better quality of life for a rich country. The healthcare sector is one of the key sectors which requires a special on going attention, particularly medically generated waste. Therefore, this research work has been conducted to investigate the status of medical waste management in the capital city; Riyadh. The prime aim of this research work is to propose a strategic framework which can be used as a roadmap for the different stakeholders.

The world waste hierarchy is changing under the pressure of growing population, strict standards of living and environmental standards, as well as new technological experiences. Strengthening of environmental standards in Europe leads to restraining the most used and cheapest waste treatment method - landfilling. The limitation of landfilling will force the countries to search for alternative treatments. This diploma thesis is supposed to give certain conclusion whether the incineration of waste with gaining energy (waste-to-energy) can be the right way how to deal with waste in the future. Current market position of waste-to-energy is being examined in selected European countries, focusing on whole environmental, economic and social aspects of using this technology. Incineration as commercially proven state-of-the-art technology is still having problems entering the new markets even if the technology with its sophisticated approach shows a great environmental service. The results of the examinations show the potential for Czech Republic, as well as other countries where WTE is not utilized yet.

Současná pandemická situace ukázala obrovské dopady rozšíření infekce na společnost, i přesto stále ještě chybí jednotný přístup k problematice infekčního odpadu. Cílem této práce je představení metodiky nakládání s infekčním odpadem v rámci regionu v kontextu situace v Česku a Evropské Unii. V teoretické části práce je uveden legislativní rámec, charakter produkce, možnosti dekontaminace a podmínky spalování infekčního odpadu. Na základě těchto poznatků je navržena metodika pro nakládání s infekčním odpadem v rámci regionu. V praktické části práce je pak metodika aplikována na konkrétní region – Královéhradecký kraj. V rámci metodiky jsou navrženy možné scénáře nakládání s infekčním odpadem a vybrány nejvhodnější z nich z pohledu zdravotních rizik, rozpočtové zátěže a dopadu na životní prostředí. Na závěr je metodika kriticky zhodnocena a srovnána s metodikami jiných studií na podobné téma.

1 Abstract Legislation on transboundary shipments of waste This thesis focuses on the legal regulations of transboundary shipments of waste. The aim of the thesis is a comprehensive and systematic summary of the current legislation on cross-border shipments of waste in Czech Republic and an explanation of its individual institutes and regimes based primarily on Regulation No. 1013/2006 and Act No. 185/2001 Coll., on waste. The first chapter is dedicated to the historical development of regulation at the international level, where the Basel Convention and OECD Decision on the Control of Transboundary Movements of Waste Destined for Recovery Operations are discussed in more detail, as well as the historical development of regulation at the European and national levels. The second and third chapters are dedicated to the current legislation, which first defines the individual basic terms and entities used across the regulation and then analyzes the various types and regimes of transboundary shipments of waste. The fourth chapter deals with the function and position of administrative bodies involved in the control and supervision of transboundary shipments of waste. The last chapter deals with the illegal activity and legal liability arising from it in the cross-border movements of waste, there are also cases of...

The use of renewable waste for bioenergy production is in discussion because of the concurrence to the food or animal feed. The treatment of organic waste is necessary in order to keep clean the environment. The combination of those proposals, the waste utilization and the production of renewable energy can be combined with several techniques. In Vietnam the energy demand will increase rapidly in the next years, because a lot of people do not have access to electricity. The development of power sources is limited mainly to large central power plants using hydropower and traditional fossil fuels. So in the country there exists a considerable potential for sustainable energy sources like biomass and residues. The biogas potential is large due to the high livestock population. There are more than 30 million animals in farms, mostly pigs, cattle, and water buffalo. There is a high potential for biogas utilization. Biogas production is economic in small and in big plants, so household biogas digesters are one opportunity for production of renewable energy in small villages or cities with a high livestock population. The advantage of anaerobic treatment of organic waste is the work in closed loops. The treatment of organic waste and the utilization of digested sludge from wastewater treatment plants are samples for the circulation of materials after use. The remaining materials can be used in the natural circulation process, because the nutrients such as nitrogen, phosphorous and carbon, and also trace elements remain in the digested matter. In biogas plants a huge variety of substrates can be used. The adaption of biogas technology to the special conditions of the substrates, the increase of the prices for energy, the aim to replace fossil energies with renewable energies will be forced in the next years. / Việc sử dụng chất thải có thể tái tạo được để sản xuất năng lượng sinh học là vấn đề còn đang được thảo luận vì sự cạnh tranh với thức ăn hoặc thức ăn cho động vật. Việc xử lý các chất thải hữu cơ là cần thiết để giữ sạch môi trường. Sự kết hợp của các đề xuất đó, tận dụng các chất thải và sản xuất năng lượng tái tạo có thể có thể được kết hợp với một số kỹ thuật. Ở Việt Nam, nhu cầu năng lượng sẽ tăng lên nhanh chóng trong những năm tiếp theo, bởi vì rất nhiều người vẫn chưa có điện sử dụng. Sự phát triển của các nguồn năng lượng chỉ giới hạn chủ yếu là các nhà máy điện lớn trung tâm sử dụng thủy điện và các nhiên liệu hóa thạch truyền thống. Vì vậy, trong nước tồn tại tiềm năng đáng kể cho các nguồn năng lượng bền vững như sinh khối và những nguồn khác. Tiềm năng khí sinh học lớn do quần thể động vật nuôi rất lớn. Có hơn 30 triệu động vật trong trang trại, chủ yếu là lợn, bò, trâu nước. Tiềm năng sử dụng khí sinh học rất cao. Sản xuất khí sinh học rất có hiệu quả kinh tế trong các nhà máy nhỏ và lớn, do đó, các thiết bị phản ứng tạo khí sinh học ở các hộ gia đình là một cơ hội để sản xuất năng lượng tái tạo trong các thành phố hay làng mạc nhỏ với số lượng lớn các gia súc được chăn nuôi. Ưu điểm của việc xử lý kỵ khí các chất thải hữu cơ là làm việc trong vòng khép kín. Việc xử lý các chất thải hữu cơ và sử dụng bùn phân hủy từ các nhà máy xử lý nước thải là các ví dụ cho việc tuần hoàn các vật chất sau khi sử dụng. Các vật chất còn lại có thể được sử dụng trong quá trình tuần hoàn tự nhiên, vì các chất dinh dưỡng như phốt pho, nitơ và carbon, và cả các nguyên tố vi lượng vẫn tồn tại trong nguyên liệu đã phân hủy. Trong các nhà máy khí sinh học, rất nhiều loại chất nền có thể được sử dụng. Sự cải tiến công nghệ sản xuất khí sinh học theo các điều kiện đặc biệt của các chất nền, sự gia tăng của giá năng lượng, mục đích thay thế nguồn năng lượng hóa thạch bằng năng lượng tái tạo sẽ là bắt buộc trong những năm tới.

The quick social economic development of Vietnam stimulates great demand of quality as well as quantity on transport service by the increasingly growing needs of customer for transportation. The railway passenger transport is currently still an important branch of a country’s transport system because it is safer, more eco-friendly and much more efficient in comparison to another means. However, the increasing of the number of passengers is the main causes of fast increasing waste amount from the rail service. The aim of this paper is to study how the organic waste from rail service is managed and treated today by the Vietnam railways. The paper ends with some proposal solutions for treating and disposing of organic waste by applying renewable energy technologies for climate change mitigation to protect human health and the environment. / Sự phát triển nhanh chóng của nền kinh tế Việt nam dẫn đến nhu cầu vận chuyển hành khách ngày càng tăng mạnh về số lượng cũng như chất lượng dịch vụ.
