Waste management

Food waste issues in relation to the mandatory reporting of its production for the needs of the Waste Framework Directive

Ing. Dagmar Vološinová, Ing. Robert Kořínek, Ph.D. and Dr. Yelizaveta Chernysh – 4/2022

From this year, the European Union member states are obliged to introduce preventive measures that will reduce the amount of food waste at all stages of the food chain. The presented paper deals with this current topic, presents possible procedures for obtaining data on food waste production at various stages of the food chain and shows the results of our own research and analysis
about the usability of these data for reporting obligations and demonstrating
future reductions.

Interview with Dr. Yelizaveta Chernysh, a new Ukrainian researcher at TGM WRI

Redakce – 4/2022

Doctor, we know that in Ukraine you worked as a researcher focusing on wastewater and waste as such. Can you briefly describe your experience? I have 10-years’ experience in research related to wastewater and sludge treatment and a long-standing collaboration in this area in Sumy region (Ukraine). I previously dealt with the basic stages of… Read more »

Grey water footprint of pollution discharged from wastewater treatment plants in the Czech Republic registered in the water balance in the period 2002–2018 – data set

Ing. Libor Ansorge, Ph.D., Mgr. Lada Stejskalová and Ing. Jiří Dlabal – 4/2022

Koncept vodní stopy byl představen v roce 2002 [1] a dnes je jedním z rozšířených nástrojů pro hodnocení udržitelnosti užívání vodních zdrojů [2]. Vodní stopa patří do rodiny environmentálních stop [3], které umožňují podívat se na problémy užívání přírodních zdrojů z jiné perspektivy. Šedá vodní stopa je kvalitativní ukazatel převádějící vypouštěné znečištění na objem vody potřebný k jeho naředění na koncentrace neškodné pro životní prostředí [4].

Study of the effectiveness of the small municipal sourcess sewage sludge extensive stabilization for their use as a fertilizer

Ing. Josef Kratina, Ph.D., Ing. Miloš Rozkošný, Ph.D., Ing. Hana Hudcová, Ph.D., Mgr. Michal Šereš and Ing. Ondřej Holubík – 6/2021

The article is devoted to the presentation of partial results of a study aimed at determining the potential use of extensive sludge dewatering technology for small municipal WWTPs (up to 1000 PE) in the conditions of the Czech Republic. The study has shown that the use of technology based on extensive sludge dewatering and their stabilization in sludge dewatering reed beds with suitable wetland vegetation can be an alternative to other technologies. Especially in combination with constructed wetland (CW) based WWTPs, which are characterized by lower sludge production.

Ash management in the circular economy of municipalities

Ing. Dagmar Vološinová, Ing. Václav Vachuška, Ing. Elžbieta Čejka, Ing. Robert Kořínek, Ph.D., Ing. Aleš Vachuška and Ing. Jan Vachuška – 6/2021

Ash from small heat sources is produced by burning solid fuels such as wood and coal. Based on a survey conducted by the article authors, ash from small heat sources can be considered the most significant waste stream in smaller municipalities in the Czech Republic. This material has considerable potential for reducing waste production, landfilling and consumption of primary raw materials.

Municipal waste management in the light of new regulations

Ing. Dagmar Vološinová, Ing. Robert Kořínek, Ph.D. and Ing. Jiří Kučera – 5/2021

Modern municipal services in solid waste management usually include cleaning and cleaning of public spaces, collection, transport, recycling and disposal of generated waste. Solid waste management services are among the most expensive and complicated municipal work systems for the public. At the same time, it can also be the least awarded communal service. Water, electricity, firefighting and police protection meet the daily needs of residents and businesses fundamentally and immediately. Therefore these services are given a much higher priority by the community and its leadership. Waste management services are usually one of the most minor „fragrant“ public services, but their flawless functionality and efficiency have far-reaching implications.

Littering

Ing. Dagmar Vološinová, Bc. David Rohovec, DiS. and Ing. Elžbieta Čejka – 3/2021

This article is available in Czech only. For translation or more information on this topic, please contact author. Úvod Při nakládání s odpady a údržbě veřejných ploch zainteresované strany čelí problému výskytu litteringu. Littering je popisován jako ekologický, sociální a estetický problém, ale málokdy je zmiňován i jeho ekonomický dopad. Uvědomění si rozsahu jeho vlivu je prvním důležitým… Read more »

Possibilities of combined ways of treatment for selected waste types using an experimental equipment for physical waste treatment with the intention of their further use

Ing. Tomáš Sezima, Ph.D., Ing. Eugen Sikora, Ph.D. and doc. Dr. Ing. Radmila Kučerová – 6/2020

This article presents possibilities of a unique device for industrial waste treatment using a patented process, and outlines possible future directions. This device, using different physical processes, individually or in synergy, e.g. combined effects of ultrasonic waves, focused microwave field, arc discharges, electrostatic field and the exposure to ultra-violet radiation, is intended to degrade dangerous substances in waste, reducing its hazardous properties for the environment and to prepare the waste for future applications (material or energy), i.e. separately or in combination with other technology processes, such as biotechnology.

Determination of selected illicit drugs in wastewater using liquid chromatography tandem mass spectrometry

Ing. Danica Pospíchalová, RNDr. Diana Marešová, Ph.D., Ing. Věra Očenášková, Bc. Tereza Šafránková and Ing. Eva Bohadlová – 2/2020

The wastewater-based epidemiology approach to the analysis of illicit drugs was conceptualized in 2001 and for the first time was applied in 2005 for cocaine estimation in Italy. Further, other illicit drugs as heroine, cannabis and amphetamine have been estimated.

Monitoring of waste services for sorted components of municipal waste in the Capital City of Prague

Ing. Dagmar Vološinová, Ing. Robert Kořínek, Ph.D. and Ing. Marcela Makovcová – 6/2019

Management of each municipality, region or state needs for its decision-making and planning basic input data, which prove actual facts. The easiest way to obtain data on production and waste management is to monitor at pre-set regular intervals.

Contribution to the history of research of wastewater treatment technologies in the Water Research Institute

Ing. Václav Šťastný – 5/2019

In the past, research on water purification technologies was carried out according to a different key than now. In addition to achieving the highest possible cleaning effect, the aim was also to reduce costs, simplify construction processes and often bypass the ignorance of know-how in operating abroad technologies.

Ways of biowaste management in Prague and in selected major cities of the European Union

Ing. Dagmar Vološinová, Ing. Robert Kořínek, Ph.D. and Ing. Elžbieta Čejka – 3/2019

Biowaste or waste subject to the anaerobic or aerobic decomposition has become a problematic component of the municipal waste due to the use of green spaces, especially in the large cities with a high population density.

Biochar – a new perspective in wastewater treatment technology, or a dead end?

Ing. Václav Šťastný – 3/2019

Biochar has a wide range of applications in the field of water technology, not only as part of the technological solution for water purification and treatment, but also as a material produced from waste products of this technology. In the article we consider the perspective of this application and the possibility and need for its research.

At the time of changing climatic conditions and reducing the quantity of raw material it is necessary to start saving water and raw materials.

Quality of sludges and wastes from household and small wastewater treatment plants and their utilization in agriculture management

Ing. Miloš Rozkošný, Ph.D., Ing. Hana Hudcová, Ph.D., Ing. Miroslav Plotěný, Ing. Radek Novotný and Ing. Jana Matysíková – 6/2015

The aim of this article is to introduce partial sections of the research projects TA02020128 and TA02021032 (Technology Agency of the Czech Republic). These parts of the projects pay attention to the issue of quality of sludge and other wastes produced in wastewater treatment plants (WWTP) using activated sludge process, anaerobic processes (including septics) and extensive (natural) wastewater treatment plants (with horizontal subsurface flow reed-beds), which also include mechanical pre-treatment.
