Practical Impact

Waste treatment consists of activities required to make sure that waste has the least practical impact on the environment. In Slovakia, more than 50% of waste is in storage. Waste development depends on the economic situation of the state. In Slovakia, there is economic intolerance of waste treatment due to the weaker economic situation of the inhabitants. The goal of this contribution is to study the development of waste production in Slovakia in regard to economic indexes of households with the aim of improving waste management. The goal is achieved by searching for a relation between economic indexes and households by a correlation matrix and by verification of polynomial dependence. According to the results of the statistical importance, we found similarity of the regions in chosen indexes by using of cluster analysis. By this method a sustainable economy and healthy environment is guaranteed and waste is used to produce energy.

Abstract Low and medium level waste management means reducing the amount of waste generated during maintenance and operation of the plant, in accordance with the ALARA concept, while keeping not only the quality of the product but also the associated costs under control. All this waste is managed by ONDRAF/NIRAS, the Belgian Federal Agency responsible for waste management, including conditioning, intermediate storage and final disposal. Unfortunately, the actions taken by ONDRAF/NIRAS and the producers in order to reduce waste production have had a negative impact on waste treatment tariffs. It has become necessary to re-examine the relationship between ONDRAF/NIRAS and the producers, in order to control the costs of waste management. This problem concerns not only the treatment costs but also the disposal costs. The volume of waste has fallen from 30M3/Thwh in 1985 to 4.m3/Twh in 2000, not by chance but as the result of a new site organisation geared towards achieving this aim. This paper presents firstly the history of Belgian waste management, taking into account the impact on the associated costs, and secondly the measures that have to be taken in order to be able to decide which new technologies are necessary to go further with the objective of waste volume reduction in a new environment, namely deregulation and consequently high pressure on production costs. Finally, it presents a few conclusions.

The increase of solid waste production is a general problem in municipality, particularly of plastic waste. The durability, light-weight, anticorrosiveness, and inexpensiveness properties of plastic make it favorable to be used in daily life, including in Salatiga. However, plastic is one of some non-biodegradable materials that could lead to soil and water pollution as it contains toxic compounds such as aromatic hydrocarbons, phthalates, and organochlorine. Various studies in municipal solid waste management have been conducted. While those studies often applied various approaches separately, researches in regard to the role of stakeholders in municipal solid waste management are very limited. This study aims to explain the plastic waste management in Salatiga based on the role of the corresponding stakeholders. This qualitative study shows that there are four stakeholders who were involved in municipal plastic waste management in Salatiga. They were the households who generate wastes, the scavengers who sorts the wastes, Bank Sampah and collectors who have the same role in order to collect the wastes and treat the plastic wastes through reusing or recycling processes, and the government. Currently, efforts in waste treatment in Salatiga are focused on the system of collecting-tranferring-disposal mode, waste treatment by reuse and recycle processing, and landfilling. Reducing plastic consumption must take into account the sociocultural aspect and environmental awareness, as the people still interested to use plastic instead of using other materials in substitution. Finally, the role of government is central to educate the community in term of sorting activities and reducing waste production, build the capacity of Bank Sampah, and manage the role of scavengers and collectors. Other alternatives include creating synergy between the collectors and Bank Sampah, as well as ensuring final treatment of the unprocessed wastes disposed by collectors and Bank Sampah.

The constant consumption of resources exerts pressure on the environment. In this sense, waste management has obtained increasing attention from the view of a circular economy. The European Union deals with these mentioned aspects, trying maintain long-term competitiveness and to provide sustainable development in accordance with all related environmental aspects. This paper focuses on the evaluation of the production of communal waste in 36 EU countries. The main aim is to evaluate the success of countries’ efforts to decrease waste production and increase recycling rates. The methodology used for the evaluation included data collected from the publicly available database Eurostat, consequent analyses and evaluation in the statistical software JMP 13 through regression, distribution, and cluster analysis, and the interpretation of the results. The results of the cluster analysis showed that despite clear EU waste management legislation, EU member states have significantly different waste management systems at the national level. However, generally, we could see positive correlation between the generation of waste and recycling rates. Although, Malta, Austria, Greece, and Norway recorded a decreasing level of waste recycling over the last several years, some countries (Slovakia, Poland, Czech Republic, Latvia, Lithuania) had significantly lower recycling rates accompanied by low landfill taxes. The evaluation of waste production and recycling can be used for government policy in the area of waste management, as well as for individual communities dealing with communal waste.

The forecast of waste production and disposal is an important requirement for a future waste management planning. The problem is very often a short time series of the database. This paper suggests an approach to forecast the production of multiple waste types in micro-regions taking into account this challenge by combining many techniques. The heuristic methodology consisting of few steps is formulated. First, the input data are transformed and the methods from cluster analysis are repetitively applied. The second step is  about a determination of quality for trend functions based on historical data. In the last step is performed the  testing. The di erent type of representatives from cluster analysis is used to calculate indices of determination which are compared. This procedure is repeated until the criteria hit. The proposed approach reduced the  computational time and managed to aggregate micro-regions with a similar trend. The forecast should have contributions in terms of building new facilities or adaptations to the existing ones, where it is necessary to estimate the production of waste for several years in advance. The article includes a case study of production forecast for several waste types in territorial units of the Czech Republic. The forecast is based on data in years 2009{2014 and following year 2015 was used to assess the quality of the nal models. In the future, the database will expand and thus it will be possible to make more precise estimates and to develop statistical methods to measure this prognostic tool.

Introduction: Waste is becoming a problem until recently in many countries. Globally, the amount of wastes has increased with the growing population and the level of consumerism in society. One investment in the future to control waste production is by providing the value of waste treatment from an early age of children. The purpose of this study was to describe the knowledge, attitude, and practice regarding waste management among primary school children. Study Design: Pre-experimental, with a one-shot case study design, was used in this study. Methodology: Forty children in primary school, aged between 11 and-12 years, were sampled in this study. The intervention was delivered through an oral presentation and play video followed by a survey using tested questionnaires contained knowledge, attitude and practice towards waste management questions. Results: More than 70% of respondents answered with a satisfying score in all questions. However, respondents had less than 70% in knowledge about waste type. Most of the respondents said there was no waste treatment facility in their schools. Respondents disliked the enactment of punishment for those who did not imbibe the spirit of waste disposal effectively and efficiently. Conclusion: Our result implies respondent knowledge about waste management is sufficient, but it is essential to push them to practice the knowledge in their daily life.

This paper discusses the topical issue which examines the development of CO2 emissions in individual countries of the European Union (EU28) for the period between 2000 and 2017. Carbon footprint is monitored in four basic economic sectors of the EU28 countries—energy, other industries, agriculture, and waste management. The purpose of this paper is to conduct a structural analysis of the percentage contribution of individual sectors while determining the average conversion of emissions in tonnes per capita for individual countries, subsequently identifying the tendencies in the development of the detected rates. A cluster analysis for the EU28 that demonstrate similar carbon footprint values in the examined economic areas is conducted for the findings. The partial aim of the paper is to perform a comparison of the monitored countries and detect whether the differences between those striving for decarbonisation are diminishing. The energy industry is the most significant contributor to emission levels. The index analysis indicates that the level of emissions throughout the EU28 in all the monitored sectors has decreased, predominantly in waste management (by 40%,) which is followed by industry (17%), energy (by 16.2%), and agriculture (by 5%). The cluster analysis conducted for 2000 and 2017 has confirmed the convergence of the identified groups of the EU28. Individual clusters of the countries thus display minor differences and converge in general.

The purpose of the study presented in this text is to show the influence of COVID-19 on waste management systems and circular economy stream, and their impact on circular economy, particularly the economic impact of the pandemic on the waste management sector, impact on circular economy objectives’ implementation as well as additional challenges like the need for hygienization of waste streams during different implementation efforts, such as changes in the municipal solid waste market and different waste processes of their disposal. Additionally, some methods—such as thermal treatment—which seemed to be not fully aligned with the circular economy approach have advantages not taken into account before. Incineration of higher volume of waste affects the waste structure and will change some of the circular economy objectives. The analysis was carried out on the example of the Polish market.

The waste management practices in primary healthcare centres of Iran were investigated in the present study. A total of 120 primary healthcare centres located across the country were selected using the cluster sampling method and the current situation of healthcare waste management was determined through field investigation. The quantities of solid waste and wastewater generation per outpatient were found to be 60 g outpatient—1 day—1 and 26 L outpatient—1 day— 1, respectively. In all of the facilities, sharp objects were separated almost completely, but separation of other types of hazardous healthcare solid waste was only done in 25% of the centres. The separated hazardous solid waste materials were treated by incineration, temporary incineration and open burning methods in 32.5, 8.3 and 42.5% of the healthcare centres, respectively. In 16.7% of the centres the hazardous solid wastes were disposed of without any treatment. These results indicate that the management of waste materials in primary healthcare centres in Iran faced some problems. Staff training and awareness, separation of healthcare solid waste, establishment of the autoclave method for healthcare solid waste treatment and construction of septic tanks and disinfection units in the centres that were without access to a sewer system are the major measures that are suggested for improvement of the waste management practices.

Due to enhanced healthcare needs brought upon by the COVID-19 pandemic, the amount of biomedical waste generated has also increased manifold across the globe. With the world in global crisis due to the recent outbreak of the COVID-19 pandemic, it has put great pressure on the biomedical waste management system in India and around the world. To control the spread of the COVID-19 virus, proper disposal of the waste is essential to reduce any risk of secondary transmission. This paper investigates the situation of biomedical waste management in the city of Thane in Maharashtra due to the onset of COVID-19 and suggests some key recommendations to the policymakers to help handle biomedical waste from possible future pandemics. The study found that there was an 81% increase in the total biomedical waste (BMW) generation in 2020, when compared to 2019 and the yellow category waste from COVID-19 centres was the highest contributor to this waste. It was also found that though there was a slight increase in yellow category waste, the total biomedical waste from non- COVID healthcare facilities (HCFs) was comparable to that of the waste generated in HCFs during 2019, revealing that there was conscious reduction in the usage of single use PPEs at non- COVID HCFs. The city, despite owning a Central Biomedical Waste Treatment Facility (CBWTF), was dependent on another incinerator at the Hazardous Waste Management Treatment facility (HWTF) for treatment of the additional waste generated. Unforeseen situation like these, expose the vulnerability of our existing biomedical waste management system and reinforces the need for investing and improving them for strengthening preparedness in the future. The situation also demands periodic education on importance of source segregation and waste reduction through rational use, disinfection and disposal of PPEs.
