Abstract:

AbstractAfter the implementation of a new waste management system, in which recycling is the most dominating process, landfill disposal still appears to be the most popular method of waste management in Poland, in which waste undergoes gradual decomposition and the influence of climate conditions, for example, air and atmospheric fallout, leads to the production of leachate and biogas emissions, which contribute to continual threats to the natural environment and humans. The above-mentioned threats can be limited by applying suitable techniques of waste treatment before its disposal. A technology that is oriented to these aims is a mechanical biological treatment (MBT) before disposal.The above-mentioned technology results is waste stabilisation and reduction of pollutant emissions. Additionally, it allows to increase the recovery of materials for recycling and to reduce the mass of waste. Finally, it is environmentally friendly.

Abstract:

Improving waste management is currently one of the priorities for Ukraine in the environmental safety. EU experience in the use of mechanical biological waste treatment technologies should be applied now in connection with the development and implementation of Regional Waste Management Plans in Ukrainian regions. The aim of the paper is to analyse the benefits and the preconditions of using mechanical biological waste treatment technologies in Ukraine, as well as barriers that may hinder the construction of mechanical biological waste treatment plants. The analysis of the eight drafts of the Regional Waste Management Plans showed that the mechanical biological waste treatment technologies market is free in Ukraine and the best option for the regions where there are cement plants operating is production of solid recovered fuel. Such types of projects could be affordable for Ukrainians with the cost recovery period more than 8 years. On the other hand there are significant obstacles of economic, organizational and technological nature to their immediate implementation i.e. low rates on waste disposal tax, partly compliance on air emissions monitoring system, absence of necessary standards etc. The priority actions to speed up mechanical biological waste treatment technologies implementation have been defined.

Abstract:

Achieving high efficiency of biological waste treatment in mechanical–biological treatment (MBT) plants requires reliable methods for measuring the degree of biodegradation of organic substances. For this purpose, several physical, chemical, and biological indices are used. This paper presents respirometric activity (AT4), biogas potential (GB21), total and dissolved organic carbon (TOC and DOC, respectively), and loss on ignition (LOI) values, as well as the correlations between the indices selected for stabilized waste produced in 18 MBT plants in Poland, which use various technologies for biological processing of the organic fraction of municipal solid waste. The study confirms that there is a linear relationship between AT4 and GB21 for stabilized waste produced in MBT plants, regardless of the waste treatment technology used. It has also been found that there is a linear relationship between AT4 and the concentration of dissolved carbon in water extract from stabilized waste. This indicates that DOC can be used for monitoring the organic matter stabilization process in mechanical–biological waste treatment plants. Its advantage is a shorter time needed for measurements in comparison to AT4 and GB21 tests.

Abstract:

Fertilization for agriculture and plantation nutrition still dominated by chemical fertilizers. Organic fertilizers utilization for soils is believed has not had the same quality as existing fertilizer standards. On the other hand, increasing waste problems has become environmental issues that have not been properly resolved. MSW process by using MBT Method is able to change the waste management system and produce RDF Fluff products as alternative fuels and compost fertilizers. Research have showed that the quality of organic fertilizer from the Mechanical Biological Treatment (MBT) process met the SNI 19-7030-2004 parameters with the total N = 1.38%, P2O5 = 0.66% and K2O = 2.34%. Production cost of making organic fertilizer is lower than NPK and the amount used for ground application is higher than NPK. Market confidence began gradually improving due to consumer increasing demand.

Abstract:

The exploitation of Mechanical Biological Treatment is quite diffused for treating fractions of Non-Differentiated Waste. A large part of the Italian Mechanical Biological Treatment facilities operate mainly by reducing and stabilizing the Non-Differentiated Waste mass before landfilling. This way of managing Mechanical Biological Treatment can be improved by the adopting a new treatment section, based on the Solid State Anaerobic Digestion process. In this way, the Waste Organic Fraction arising from the mechanical sorting of the Non-Differentiated Waste can be treated before the aerobic stabilization section of the existing Mechanical Biological Treatment. In Italy more than 40% of the working Mechanical Biological Treatment facilities have features suitable for being upgraded with a new Solid State Anaerobic Digestion section. In these plants the amount of the rapidly biodegradable fraction is about 1,100,000 tonnes per year, leading to the production of about 300 GWh of renewable energy. The results concerning a real case study show that, with the adoption of a new Solid State Anaerobic Digestion section, about 150 kWh of electric energy would be able to be produced per each tonne of Waste Organic Fraction. Furthermore, there would be a significant reduction in the Organic Load Rate [kgVS/m3*day] for the existing aerobic section of the plant, leading to additional savings of 160-320 kWh per day, depending on the amount of Waste Organic Fraction diverted from the Solid State Anaerobic Digestion. Results from the economic analysis show that the Solid State Anaerobic Digestion treatment cost ranges from about 6 up to 23 € per each tonne of Non-Differentiated Waste entering the existing Mechanical Biological Treatment plant.

Abstract:

The mechanical treatment of waste using specialized equipment allows the separation of significant amounts of secondary raw materials. To a large extent, the effectiveness of such a process depends on the quality of the input – one efficiency value is achieved during the segregation of mixed municipal waste, and the other one – during preprocessing of waste from separate collection. The work analysed the data on mechanical processing in a mechanical-biological treatment plant for municipal waste. The mechanical part of the installation is equipped with optical-electronic and electromagnetice separators, as well as manual sorting cabins. Results were obtained to compare the efficiency of the separation of secondary raw materials and energy fractions for further use, as well as the amount of undersieve fraction requiring biological stabilization and ballast waste, which are directed to landfilling.

Abstract:

Abstract The article discusses an innovative system used for aerobic biostabilisation and biological drying of solid municipal waste. A mechanical–biological process (MBT) of municipal solid waste (MSW) treatment were carried out and monitored in 5 bioreactors. A two-stage biological treatment process has been used in the investigation. In the first step an undersize fraction was subjected to the biological stabilisation for a period of 14 days as a result of which there was a decrease of loss on ignition, but not sufficient to fulfill the requirements of MBT technology. In the second stage of a biological treatment has been applied 7-days intensive bio-drying of MSW using sustained high temperatures in bioreactor. The article presents the results of the chemical composition analysis of the undersize fraction and waste after biological drying, and also the results of temperature changes, pH ratio, loss on ignition, moisture content, combustible and volatile matter content, heat of combustion and calorific value of wastes. The mass balance of the MBT of MSW with using the innovative aeration system showed that only 14.5% of waste need to be landfilled, 61.5% could be used for thermal treatment, and nearly 19% being lost in the process as CO2 and H2O.

Abstract:

Municipal waste treatment plants are a special kind of municipal facility, which, in addition to the benefits of waste management, are also an important source of energy from the biogas captured. However, the processes and unit operations carried out at waste management plants are associated with the emission of dust and chemical compounds. This paper presents the results of research aimed at analyzing indoor air conditions at a biogas plant having an installation for mechanical-biological waste treatment in places where employees work. Tests include measuring the respirable and non-respirable dust fractions and measuring volatile organic compounds (VOCs) and ammonia (NH3).

Abstract:

Abstract Waste water treatment plants are complex systems consisting of construction, hydro-mechanical, electrical, monitoring and automation equipment. Monitoring activities emphasize that the processes are dynamic; wastewater quality at the entering point of treatment plant varies in a wide range. Treatment technologies adopted must reduce major pollutants; that involves nitrification-denitrification processes and biological and chemical reduction of phosphorus through mechanical-chemical-biological treatment pathways. Increasing the activated sludge concentration in a wastewater treatment plant is an effective method by altering the process dynamics and by reducing the produced sludge volume. There are proposed and discussed in terms of technical and cost efficiency different technological wastewater treatment schemes. In Romania, wastewater treatment plants and sewage systems operating involve processes based on the new systems overrated, there is mandatory to diminish quantities in water supply systems and to exclude improperly working of wastewater pre-treatment stations. Those operations impose technological measures ensuring efficient functioning regardless the service conditions.

Abstract:

In recent times, there have been an enormous increase in the number and capacity of mechanical–biological treatment (MBT) plants all over the world owing to the need for finding sustainable solutions to the mixed municipal solid waste (MSW) problem. The objective of this study was to understand the technical and financial aspects of two MBT plants located in Bengaluru, India. Both plants treat mixed MSW. Of the two plants in Bengaluru, only one is financially stable and operating since 1975. The major product generated by this plant is compost. The second one was started in 2015 and closed after a year of operation. It was generating refuse-derived fuel (RdF) and compost. Compost and RdF generated by these MBT plants have limited market acceptance. Major challenges faced by both MBT plants in Bengaluru are untrained human resources, limited market demand for their products, budgetary constraints, inadequate infrastructure and unreliable MSW generation and composition data.

Abstract:

The dairy-processing industry generates various types of organic wastes, which are utilised as stock feed, for anaerobic digestion, spread on land or alternatively land-filled at high costs. Owing to the generation of renewable energy, anaerobic digestion is an attractive option for many factories. To enhance the biological degradation process, a mechanical disintegration of various waste dairy streams was undertaken. While the successful application of ultrasonic treatment has been reported for various municipal waste streams, limited information was available for dairy industry applications. The results of this study showed that ultrasonic treatment can improve the digestibility of the more problematic dairy waste streams, such as sludges, by breaking down micro-organisms' cell walls and releasing soluble cell compounds. For more soluble streams, such as dairy factory effluent, an increased gas production was observed and attributed to the reduced particle size of the fat globules.

Abstract:

The mechanical-biological waste treatment plants (MBTP), which include the municipal waste biogas plants, have an important role in sustainable urban development. Some plants are equipped with a sewage pre-treatment plant, which is then directed to the sewerage system and the treatment plant. Others, on the other hand, have only a non-drainage tank. The parameters of technological sewage (TS) or processing technology could reduce sewage contamination rates. In addition to the quality of sewage from waste treatment plants, the emission of odours is also an important problem, as evidenced by the results obtained over the sewage pumping station tank. The conducted statistical analysis shows a significant positive correlation between odour concentration (cod) and volatile organic compounds (VOCs). Analysing the individual compounds, a high positive correlation was also found—the strongest being between H2S, NH3 and VOCs. In the case of sewage compounds, the insignificant correlation between P total and other parameters was found. For the rest of the compounds, the highest positive correlation was found between COD and BOD and N-NO2 and N-NH3 as well as COD and N-NO2. The dilution of sewage is only an ad hoc solution to the problem. Further work should be aimed at reducing sewage pollution rates. The obtained results indicate large pollution of technological sewage and a high level of odour and odorants concentration. The novelty and scientific contribution presented in the paper are related to analyses of various factors on technological sewage parameters and odour and odorant emission from TS tank at biogas plant processing municipal waste, which may be an important source of knowledge on the management of TS, its disposal and minimisation of emitted compound emissions.

Abstract:

Mechanical and biological pre-treatment (MBT) of residual Municipal Solid Waste (MSW) is considered as a promising technical option prior to landfilling. The aim of MBT is to control the biological landfill activity to minimize biogas and leachate production. Laboratory-scale bioreactors were set up to study the behaviour of untreated and pre-treated residues. The bioreactors were designed to simulate the anaerobic condition of sanitary landfill. Initial water addition has been performed to ensure optimal condition of biological degradation. The incubation time was 400 days to achieve the biodegradation. Experiments have been carried out with untreated or treated waste collected from a mechanical-aerobic biological treatment plant located in middle south of France. Chemical and biological analyses have been performed to characterise the waste samples before and after the incubation. Results showed that a residual anaerobic activity does exist for the pre-treated waste when incubated in optimal moisture condition: biogas production does still exist even after a long period of aerobic hot fermentation and maturation.

Abstract:

The performances of an integrated system based on mechanical biological treatment and bioreactor landfill with leachate recirculation for managing the mixed municipal solid waste generated in a given Italian district were investigated. In the mechanical biological treatment the municipal solid waste was mechanically sorted into two main streams: a dry and a mechanically sorted organic fraction consisting of 45,000 tonnes year−1. After being sorted the mechanically sorted organic fraction was aerobically pretreated before being disposed of in the 450,000 m3 bioreactor landfill. Experimental runs showed that an aerobic pretreatment period ranging from 15 to 30 days was able to maximize the methane generated by the mechanically sorted organic fraction once landfilled up to 10 Nm3 tonne−1. The aerobic pretreatment leads to a significant volatile solids reduction in the first 30 days, after which the volatile solids concentration remained quite constant. Similarly the potential dynamic respirometer index was significantly reduced in the first 15 days of the aerobic pretreatment decreasing from about 5,000 to about 3,500 mgO2kgVS−1h−1. The whole amount of electrical energy producible by the landfill ranged from 18.5 kWh tonne−1 to 21 kWh tonne−1, depending on the strategies adopted for the activation in bioreactor mode of each landfill cell by the leachate recirculation.

Abstract:

Residual municipal solid waste can be treated by anaerobic digestion after a sorting process in order to remove the unwanted materials. After a mechanical sorting the quality of the final compost can hardly cope with requirements for agriculture use. In this way, a more efficient sorting process using a specific equipment that provides a combined biological and mechanical effect, has been implemented on the plant of Varennes Jarcy prior to anaerobic digestion. This paper presents the main results obtained on this plant. The reduction of biodegradable organics in particle lower than 10 mm allows a very efficient separation by screening. An additional ballistic sorting removes the remaining glass. The composition of the resulting sorted waste was close to a source-sorted organic fraction. The sorted waste exhibit methane yields comparable with raw biodegradable organics, showing that the pre-treatment had little impact on anaerobic digestion performance.

Abstract:

The article describes the diversity of oil products that are the main sources of wastewater pollution. The dissolved or liquefied oil forms a floating layer on the water surface. The large emissions of different crude oil sources and household waste into the environment cause great damage to wildlife. It is evident that many types of oil sources are carcinogens. The article provides information on emissions of toxic compounds of industrial enterprises into the atmosphere and their adverse effects, including on human health because toxic compounds can cause many diseases. The methods of biotechnological treatment by mechanical, physicochemical and biological purification of water sources contaminated with oil waste are discussed. In particular, the importance of biological purification, petroleum technology, and microbiological purification and nanotechnological methods of water purification has been widely examined. The article contains information on water purification method using microalgae, biological filters, and wastewater treatment through aerotanks. Methods to purify phenolic compounds from wastewater such as adsorption, ion exchange, liquid-liquid extraction, chemical oxidation, electrochemical methods, solvent extraction, precipitation and biodegradation are considered. The role of some economically efficient and promising methods of bioremediation to eliminate and neutralize petroleum hydrocarbons and some pollutants in removing phenolic compounds is analysed.

Abstract:

This paper describes the laboratory-scale simulation of the behaviour of rejects from a biological-mechanical treatment (BMT) plant in Castellón (Spain). For this purpose, four lysimeters were built, with different densities. Simulations were carried out for 7 weeks and leachate recirculation was applied to two of them. The experimental results allowed us to determine: (i) dirt in fractions, which was relatively high (up to 15% in some fractions) due to biological processes; (ii) the field capacity for this waste with similar values to other works, which varied depending on the experiment; (iii) variation in the biomass percentage which lowered after experiments in all cases (59.5% lower on average), and the rejects’ calorific value was higher after experiments (28.2% on average); (iv) the evolution of leachate properties with or without recirculation, where percolation, in addition to the dragging of soluble materials, stabilised waste, which diminished its biological activity. Rejects’ increased calorific value will allow combustible material to be recovered in the future as a way to exploit the energy potential stored in landfills.

Abstract:

Abstract The paper presents examples of installations for the mechanical and biological treatment of municipal waste in Poland. Each of the presented installations is defined as a regional municipal waste treatment installation (RIPOK). Their technological solutions and work efficiency have been compared in this study. In addition, the loss of waste mass as a result of processes occurring in the biological part of individual installations was calculated in the research. The paper refers to the National Waste Management Plan (KPGO 2022) regarding the circular economy. As intended by the circular economy, MBP installations will be transformed into installations that will treat selectively collected municipal waste and become Regional Recycling Centers (RCR).

Abstract:

An Austrian research project focused on the development of process indicators for treatment plants with different process and operation modes. The whole treatment scheme was subdivided into four processes, i.e. mechanical pretreatment (Process 1), mechanical-biological waste water treatment (Process 2), sludge thickening and stabilisation (Process 3) and further sludge treatment and disposal (Process 4). In order to get comparable process indicators it was necessary to subdivide the sample of 76 individual treatment plants all over Austria into five groups according to their mean organic load (COD) in the influent. The specific total yearly costs, the yearly operating costs and the yearly capital costs of the four processes have been related to the yearly average of the measured organic load expressed in COD (110 g COD/pe/d). The specific investment costs for the whole treatment plant and for Process 2 have been related to a calculated standard design capacity of the mechanical-biological part of the treatment plant expressed in COD. The capital costs of processes 1, 3 and 4 have been related to the design capacity of the treatment plant. For each group (related to the size of the plant) a benchmark band has been defined for the total yearly costs, the total yearly operational costs and the total yearly capital costs. For the operational costs of the Processes 1 to 4 one benchmark (€ per pe/year) has been defined for each group. In addition a theoretical cost reduction potential has been calculated. The cost efficiency in regard to water protection and some special sub-processes such as aeration and sludge dewatering has been analysed.

Abstract:

In the process of wastewater treatment there are generated products that wastewater treatment plant operators want to eliminate. The most important product – waste generated in mechanical-biological treatment of wastewater – is sludge. Bratislava Water Company (BVS) operates three wastewater treatment plants (WWTP) with different mechanical-biological treatment technologies in the region of the Slovak capital. The total capacity of these WWTP is 1,515,000 population equivalent (p.e.). The WWTP serve the needs of about 557,000 p.e. who produce about 140,000 m3/day of wastewater. Annual production of mechanically dewatered anaerobically stabilized sludge is about 560,000 tons. At present, the biogas obtained from sludge is used for bioenergy production. The resulting thermal energy is used for technological purposes such as heating of operating premises and sludge digestion tanks. The obtained sludge is further recovered as a component in production of industrial compost or it can also be used for direct application to agricultural or forest land (if appropriate composition).
