The aim of this paper is to determine upcoming trends for use of the energy potential of municipal solid waste in Kyiv city, Ukraine. The current state and development prospects of this area of waste management is considered. This article presents the approaches to the use of energy potential of municipal solid waste in Poland.  It is demonstrated that the amount of Waste-to-Energy Plant in Poland has been growing dynamically after 2015. This approach is consistent with the goals set by the National Waste Management Strategy in Ukraine. An analysis of the energy potential of municipal solid waste in Kyiv showed that the energy efficiency of mixed solid waste incineration differs slightly from incineration of RDF combined with biogas. The main factors affecting the economic efficiency of thermal treatment of MSW are capital costs of the construction of plants with a high-quality system for flue-gas cleaning, operating costs of energy production and the cost of raw materials. Combined mixed waste incineration at Waste-to-Energy Plant entails only capital costs. The introduction of the technology of mechanical and biological treatment of MSW requires additional capital costs of the construction of MBT systems. Operating costs of the production of RDF and biogas increase fuel costs. It has been demonstrated that the most appropriate approach for burning of MSW in Kiev is the construction of a Waste-to-Energy Plant. The discrepancy between the amount of MSW produced in Kyiv city and the statistical population of the last is shown, which confirms that a significant number of unregistered residents live in the capital.

Abstract Refuse-derived fuel (RDF) can be produced from combustible materials contained in municipal waste. After pre-treatment of waste it is possible shipping RDF a waste-to-energy plant (WtE). This article investigates energy and material flow of waste for different scenarios for production of RDF from bulky waste, separately collected waste, and mixed municipal solid waste (MSW). We compare the proportion of energy consumption in transportation, handling waste, and processing using data from the waste collection company in the South of Poland. The findings show the components of the reverse supply chain consuming the highest value of the energy. A model of material and energy flow has taken into consideration collection of waste and transportation by two categories of waste collection vehicles light commercial vehicles and garbage trucks. The shipping of RDF from pre-treatment facility uses – tipper semi-trailers and walking floor trailers. The findings of the study show production of RDF from municipal solid waste is consuming almost 10% of energy potential in RDF. Less energy is required for the production of RDF from bulky waste 2.2% – 4.8% or separately collected waste 1.7% – 4.1% depending on the efficiency of collection and selected vehicles. The transportation is consuming greatest portion of energy. For mixed municipal solid waste (MSW) it can reach 79%, for separated collection waste 90% and for bulky waste up to 92% of the total energy consumed. Comparing emissions for two categories of the collection vehicles there is no significant difference for the bulky waste collections. For mixed MSW and separately collected waste the emissions are higher for garbage trucks. As a recommendation for practitioners is optimization of routing to achieve higher collection rate for minimized route length. Transportation of RDF to WtE plant the vehicles with higher loading capacity are essential.

Energy Potential

Conversion of Solid waste into energy is the most resourceful process to combat landfill saturation and environmental impression. Bhutan, with an exponential rise in the waste production, Waste to Energy (WTE) conversion is an alternative solution for municipal solid waste management (MSW). The study for MSW composition and its energy potential analysis for Memelakha (Thimphu) and Pekarshing (Phuntsholing) landfills was done to resolve the waste management challenges in the country. The standard number of samples from two dumpsites were used to analyze for the waste characterization (waste composition, proximate analysis, chemical analysis) and high heating value (HHV) of MSW. MSW of two landfills showed that the main elemental constituents were Carbon and Oxygen with 17.26% and 9.97% by mass respectively for Pekarshing and 16.52% (Carbon) and 11.07% (Oxygen) by mass for Memelakha landfill. Based on the physio-chemical analysis of MSW, the average calorific HHV of MSW obtained were 10.028 MJ/kg (26.04% of coal energy) for Pekarshing dumpsite and 9.6 MJ/kg (24.94% of coal energy) for Memelakha. The analysis showed that by the year 2050 Memelakha landfill has the potential to generate the power of 8.85 Megawatt (MW) and 1.44 Megawatt (MW) for Pekarshing. For (WTE) conversion, incineration, pyrolysis, and gasification technologies are found suitable based on the current composition MSW of Bhutan. Furthermore, in terms of energy efficiency and percentage of wastage, the gasification process was the most feasible method for WTE conversion at two locations with a waste volume reduction of 80 to 90 percent at the landfill.

Air Pollution Control Residues

A common perception of plasma arc treatment systems for municipal solid waste incineration ash is that the resulting vitrified slag is inert from an environmental perspective. Research was conducted to examine this hypothesis and to assess whether reduced pollutant release results from pollutant depletion during the process of the ash with plasma, or encapsulation in the glassy vitrified matrix. The concentrations of four discrete municipal solid waste incineration ash samples before and after plasma arc vitrification in a bench-scale unit were compared. Slag and untreated ash samples were leached using several standardized approaches and mobility among the four metals of interest (e.g. As, Cd, Pb and Sb) varied across samples, but was generally high (as high as 100% for Cd). Comparison across methods did not indicate substantial encapsulation in the vitrified slag, which suggests that reduced pollutant release from plasma arc vitrified slag is due to pollutant depletion by volatilization, not encapsulation. This has significant implications for the management of air pollution control residues from waste-to-energy facilities using plasma arc vitrification.

This study determines the tipping fee of municipal solid waste in the city of Depok. Two methods used to determine the fee were the income and outcome approach, and the limited resource approach. Two conditions were assumed (i.e., waste management and landfill gas bioreactor availability). From the results, the ideal tipping fee was 97,704 IDR/tonne and the application of a landfill gas reactor could boost income, thus reduced the amount of the fee collected, especially in the early years of the landfill bioreactor in operation. The fees were 40,032 and 63,337 IDR/tonne for scenario 1 and 2, respectively.

The need for resilience and an agile waste management system in Saudi Arabia is vital to control safely the rapid growth of its municipal solid waste (MSW) with minimal environment toll. Similarly, the domestic energy production in Saudi Arabia is thriving and putting a tremendous pressure on its huge reserves of fossil oil. Waste to energy (WTE) plants provides a golden opportunity for Saudi Arabia; however, both challenges (MSW mitigation and energy production) are usually looked at in isolation. This paper at first explores the potential of expanding the WTE energy production in the eastern province in Saudi Arabia under two scenarios (complete mass burn with and without recycling). Secondly, this study analyzes the effect of 3Rs (reduce, reuse, recycle) practices implementation in a residential camp (11,000 population) to influence the behavior of the camp’s citizens to reduce their average waste (kg/capita). The results of the 3R-WTE framework show a potential may reach 254 Megawatt (MW) of electricity by year 2030. The 3R system implementation in the camp reduced MSW production from 5,625 tons to 3000 tons of household waste every year, which is considered lower than what the surrounding communities to be produced in the same area.
