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.

Persistent water pollutants: case of ethylenediaminetetraacetic acid in the Czech Republic
Prášek, Jan ; Šauer, Petr ; Keprtová, Karolína
Reuse and recycling of products composed of natural matter is relatively without significant environmental problems. However, recycling of products produced using modern synthetic technologies often brings new challenges. Our analysis has shown that substitution of citric acid with artificial substance of ethylenediaminetetraacetic acid causes important environmental problems. The case study carried out in the Elbe river basin shows that the ethylenediaminetetraacetic acid concentration standard has been exceeded, particularly from confluence of the Vltava and Elbe rivers. Open questions and tasks for future technological development and environmental policies are formulated, particularly the idea to replace artificial substances with nature-based ones. This would enable better introduction of circular economy ideas in the use of resources.

Methods of landfill gas treatment in landfills in integrated prevention system
Keprtová, Karolína ; Kolář, Jan
The article focuses on the issue of landfill gas man-agement in landfills, which are within the scope of Act No. 76/2002 Coll., on integrated prevention. Al-though landfilling as a way of disposing of municipal waste is in decline, the subsequent care of landfills will continue for another decade after their closure, and landfill gas must be captured even then. The article summarizes infor-mation on the method of landfill gas management ob-tained through the information system of integrated pre-vention as well as the rules for landfill gas management according to the valid Czech technical standards. Accord-ing to data obtained from the public database of the inte-grated prevention system, 136 relevant landfills were identified. The application of a cogeneration has the larg-est share in the way of landfill gas management. If a co-generation unit is installed at the landfill, it is in most cases operated by a company other than the landfill oper-ator. It was also found that the region with the lowest population density has the largest number of landfills with low capacity. Due to the fact that the production of landfill gas decreases over time, it is possible that there will be changes in the way landfill gas is handled at indi-vidual landfills.

Indirect discharge of industrial wastewater into sewerage
Keprtová, Karolína ; Kolář, Jan
Wastewater discharge is one of the sources of environmental pollution. The main sources of wastewater pollution are industrial wastewaters. After treatment, industrial wastewater can be discharged directly into the recipient or indirectly into a sewerage network terminated by another stage of wastewater treatment. Indirect wastewater discharges are governed by the contractual relationship between the wastewater producer and the sewerage network operator. Limits for indirectly discharged wastewater are not set by legislation. It is only in recent years that the regulation of indirect discharges of wastewater has been promoted in Commission implementing decisions establishing best available techniques (BAT) conclusions, under Directive 2010/75/EU of the European Parliament and of the Council (BAT conclusions).

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.

Integrovaná prevence jako nástroj pro efektivní a ekologicky šetrnou výrobu
Keprtová, Karolína ; Kolář, Jan
Životní prostředí funguje jako systém vzájemně provázaných složek, které mezi sebou mohou sdílet živiny, energii, ale i antropogenní znečištění. Fakt, že jsou jednotlivé složky životního prostředí propojené, je třeba reflektovat i v přístupu k prevenci a omezování znečištění. Integrované povolování představuje jeden z průřezových nástrojů ochrany životního prostředí, neboť působí v ochraně životního prostředí jako celku, přičemž komplexní a integrovaná ochrana je zprostředkována jak snahou o regulaci a snižování emisí působících na všechny složky životního prostředí, tak snahou o spojení jednotlivých povolení pro vypouštění emisí do jednotlivých složek životního prostředí.
